    Prion disease is an infectious and fatal neurodegenerative disease. Western blotting (WB)-based identification of proteinase K (PK)-resistant prion protein (PrPres) is considered a definitive diagnosis of prion diseases. In this study, we aimed to detect PrPres using formalin-fixed paraffin-embedded (FFPE) specimens from cases of sporadic Creutzfeldt–Jakob disease (sCJD), Gerstmann–Sträussler–Scheinker disease (GSS), glycosylphosphatidylinositol-anchorless prion disease (GPIALP), and V180I CJD. FFPE samples were prepared after formic acid treatment to inactivate infectivity. After deparaffinization, PK digestion was performed, and the protein was extracted. In sCJD, a pronounced PrPres signal was observed, with antibodies specific for type 1 and type 2 PrPres exhibited a strong or weak signals depending on the case. Histological examination of serial sections revealed that the histological changes were compatible with the biochemical characteristics. In GSS and GPIALP, prion protein core-specific antibodies presented as PrPres bands at 8–9 kDa and smear bands, respectively. However, an antibody specific for the C-terminus presented as smears in GSS, with no PrPres detected in GPIALP. It was difficult to detect PrPres in V180I CJD. Collectively, our findings demonstrate the possibility of detecting PrPres in FFPE and classifying the prion disease types. This approach facilitates histopathological and biochemical evaluation in the same sample and is safe owing to the inactivation of infectivity. Therefore, it may be valuable for the diagnosis and research of prion diseases.

    Background and Aims: Because the accuracy of the Fibrosis-4 (FIB-4) index for predicting liver fibrosis changes with age, the need for different cut-offs in various age groups has frequently been discussed. We developed the age-independent score, the Fibrosis-3 (FIB-3) index, and have shown its usefulness in patients with metabolic dysfunction-associated steatotic liver disease (MASLD). This study aimed to validate the diagnostic ability of the FIB-3 index to predict fibrosis progression using a large new patient cohort. Methods: The ability of the FIB-3 index to predict liver fibrosis was analyzed by comparing it with that of the FIB-4 index using data from 1398 patients with MASLD enrolled in the Asia-based clinical outcome NAFLD study. Results: The areas under the receiver operating characteristic curves for predicting fibrosis stage F3 or higher were not different between the FIB-3 and FIB-4 indices in the entire cohort. Using the single ideal cut-offs of the indices (3.41 for FIB-3 index and 2.01 for FIB-4 index), the predictive accuracy of the FIB-3 index was not significantly different from that of the FIB-4 index among patients aged <60 years; however, the accuracy of the FIB-3 index was significantly higher than that of the FIB-4 index in those aged ≥60 years (0.645 and 0.529, respectively; p < 0.0001). Conclusion: The high ability of the FIB-3 index with a single cut-off to predict liver fibrosis in patients with MASLD was confirmed. The FIB-3 index could serve as a useful tool for assessing liver fibrosis regardless of age.

    KEY CLINICAL MESSAGE: Accurately identifying fulminant demyelinating diseases is important for sudden onset of asymmetric cerebral white matter lesions with mass effect. Initially, immunotherapy should be administered; however, surgical intervention should be performed with poor response to medical management and evident signs of cerebral herniation. ABSTRACT: A case of fulminant demyelinating disease of the central nervous system that required decompressive craniectomy 8 days after symptom onset is presented. The patient recovered without sequelae after a combination of neurosurgery and immunotherapy with steroids and has remained relapse-free for 4 years.

    Aims: A multi-stakeholder consensus has proposed MASLD (metabolic dysfunction-associated steatotic liver disease). We aimed to investigate the pathological findings related to the mid-term mortality of patients with biopsy-proven MASLD in Japan. Methods: We enrolled 1349 patients with biopsy-proven MASLD. The observational period was 8010 person years. We evaluated independent factors associated with mortality in patients with MASLD by Cox regression analysis. We also investigated pathological profiles related to mortality in patients with MASLD using data-mining analysis. Results: The prevalence of MASH and stage 3/4 fibrosis was observed in 65.6% and 17.4%, respectively. Forty-five patients with MASLD died. Of these, liver-related events were the most common cause at 40% (n = 18), followed by extrahepatic malignancies at 26.7% (n = 12). Grade 2/3 lobular inflammation and stage 3/4 fibrosis had a 1.9-fold and 1.8-fold risk of mortality, respectively. In the decision-tree analysis, the profiles with the worst prognosis were characterised by Grade 2/3 hepatic inflammation, along with advanced ballooning (grade 1/2) and fibrosis (stage 3/4). This profile showed a mortality at 8.3%. Furthermore, the random forest analysis identified that hepatic fibrosis and inflammation were the first and second responsible factors for the mid-term prognosis of patients with MASLD. Conclusions: In patients with biopsy-proven MASLD, the prevalence of MASH and advanced fibrosis was approximately 65% and 20%, respectively. The leading cause of mortality was liver-related events. Hepatic inflammation and fibrosis were significant factors influencing mid-term mortality. These findings highlight the importance of targeting inflammation and fibrosis in the management of patients with MASLD.

    Importance of ALT levels of >30 in patients with MASLD: Nara Declaration 2023
    The Nara Declaration 2023 recommends that patients with ALT levels of >30 U/L and those who have steatosis, diabetes, hypertension, and/or dyslipidemia should be referred to a hepatologist, considering the results of the FIB4 index and/or platelet count. ALT levels of >30 U/L is a simple and useful indicator and, when combined with the FIB4 index and platelet count, can detect MASLD cases that require further treatment and follow-up. Moreover, among patients with MAFLD and ALT levels of ≤30 U/L, the FIB4 index may be useful for identifying those at risk of MASLD. The Nara Declaration 2023 is an important and convenient guideline that provides primary care doctors with specific indications for referral to a hepatologist. When combined with the FIB4 index, ALT levels of >30 U/L is expected to predict high-risk MASLD cases.

    Background/Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) was recently proposed as an alternative disease concept to nonalcoholic fatty liver disease (NAFLD). We aimed to investigate the prognosis of patients with biopsy-confirmed MASLD using data from a multicenter study. Methods: This was a sub-analysis of the Clinical Outcome Nonalcoholic Fatty Liver Disease (CLIONE) study that included 1,398 patients with NAFLD. Liver biopsy specimens were pathologically diagnosed and histologically scored using the NASH Clinical Research Network system, the FLIP algorithm, and the SAF score. Patients who met at least one cardiometabolic criterion were diagnosed with MASLD. Results: Approximately 99% of cases (n=1,381) were classified as MASLD. Patients with no cardiometabolic risk (n=17) had a significantly lower BMI than patients with MASLD (20.9 kg/m2 vs. 28.0 kg/m2, P<0.001), in addition to significantly lower levels of inflammation, ballooning, NAFLD activity score, and fibrosis stage based on liver histology. These 17 patients had a median follow-up of 5.9 years, equivalent to 115 person-years, with no deaths, liver-related events, cardiovascular events, or extrahepatic cancers. The results showed that the prognosis for pure MASLD was similar to that for the original CLIONE cohort, with 47 deaths and one patient who underwent orthotopic liver transplantation. The leading cause of death was extrahepatic cancer (n=10), while the leading causes of liver-related death were liver failure (n=9), hepatocellular carcinoma (n=8), and cholangiocarcinoma (n=4). Conclusions: Approximately 99% of NAFLD cases were considered MASLD based on the 2023 liver disease nomenclature. The NAFLD-only group, which is not encompassed by MASLD, had a relatively mild histopathologic severity and a favorable prognosis. Consequently, the prognosis of MASLD is similar to that previously reported for NAFLD.

    Current WHO terminology and recent publications have classified tumoral (grossly visible) intraductal pre-invasive neoplasms of bile duct (TIDN) into three categories: intraductal papillary neoplasm of bile duct (IPNB), intraductal papillary oncocytic neoplasm (IOPN), and intraductal tubulopapillary neoplasm (ITPN). A total of 227 cases of TIDN and related lesions ≥3 mm in height were examined by 10 biliary pathologists referring to these 3 categories and two pathologic gradings: two-tiered system (low- and high-grade dysplasia) and modified types 1 and 2 subclassification. Among them, IPNB was the most frequent (183 cases), followed by IOPN (28 cases), while ITPN was rare (2 cases), and interobserver agreement in this classification was “substantial” (κ-value, 0.657). The interobserver agreement of two-tiered grading system of TIDN was “slight” (κ-value, 0.201), while that of modified types 1 and 2 subclassification was “moderate” (κ-value, 0.515), and 42 % were of type 1, and 58 % were of type 2. Type 1 TIDN showed occasional stromal invasion (6.7 %), whereas type 2 TIDN was frequently associated with stromal invasion (49.6 %) (p < 0.01). In conclusion, the classification of TIDN into three categories and modified types 1 and 2 subclassification are a practically applicable classification and grading system for TIDN.

    Background and Aims: The diagnostic performance of the Fibrosis-4 (FIB-4) index and nonalcoholic fatty liver disease (NAFLD) fibrosis score (NFS) is poor in patients with type 2 diabetes mellitus (T2DM). We determined the usefulness of the Enhanced Liver Fibrosis (ELF) test in patients with T2DM. Methods: A total of 1228 patients with biopsy-proven NAFLD were enrolled. The diagnostic performance of the ELF test for predicting advanced fibrosis in participants with or without T2DM was evaluated in comparison with the FIB-4 index and NFS. Results: Overall, the area under the curve of the ELF test for predicting advanced fibrosis was greater (0.828) than that of the FIB-4 index (0.727) and NFS (0.733). The diagnostic performance of the ELF test (area under the curve, 0.820) was also superior to that of the FIB-4 index (0.698) and NFS (0.700) in patients with T2DM. With the low cutoff values for each noninvasive test, the ELF test provided an acceptable false negative rate (cutoff value 9.8, 6.7%) in this population, unlike the FIB-4 index (1.30, 14.5%) and NFS (−1.455, 12.4%). After propensity score matching to avoid selection bias including age, sex, body mass index, and the prevalence of advanced fibrosis, the ELF test with a low cutoff value showed a high sensitivity (≥91.4%) and a high negative predictive value (≥96.8%), irrespective of the presence or absence of T2DM. Conclusions: The high diagnostic performance of the ELF test for predicting advanced fibrosis in individuals with or without T2DM could address an unmet medical need for accurate assessment of liver fibrosis in patients with diabetes and NAFLD.

    Background: Papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma (FTC) are common differentiated thyroid cancers, but the detection of a collision tumor is an extremely rare event. Case presentation: The patient was a 69-year-old Japanese female with multiple cervical lymph node swellings and a thyroid tumor. Preoperative fine needle aspiration cytology of the enlarged lymph node revealed a cytological diagnosis of papillary thyroid carcinoma (PTC). A total thyroidectomy, right cervical dissection and paratracheal dissection were performed. Histopathological and immunohistochemical analyses of resected specimens revealed a collision tumor of PTC and FTC. Multiple metastases of papillary carcinoma were found in the dissected lymph nodes. In the PTC lesion, IHC for BRAF (V600E) was positive but negative for the FTC lesion. Genetic analyses further revealed a TERT promoter C228T mutation in PTC and a NRAS codon 61 mutation in FTC. The patient died of recurrent cancer 8 months after surgery. Conclusions: A case of a collision tumor of PTC and FTC is very rare, and even fewer cases have been subjected to genetic scrutiny. The present case was successfully diagnosed by pathological examination using immunohistochemical and genetic analyses. The TERT promoter mutation in the PTC lesion was consistent with the aggressive behavior of the cancer.

    Background: Elevated creatinine concentrations often indicate acute renal injury and renal biopsies are considered in this situation. However,pseudohypercreatininemia is potential cause of elevated creatinine concentrations, and invasive interventions should be avoided. Case presentation: A 54-year-old woman underwent surgery for descending aortic dissection.Nine days postoperatively, her creatinine concentration increased from 1 mg/dl to 5.78 mg/dl (normal range, 0.47–0.7 mg/dl). Azotemia and hyperkalemia were absent and physical examination findings were unremarkable. Cystatin C concentration was 1.56 mg/l (normal range, 0.56–0.8 mg/l) and pseudohypercreatininemia was suspected. Testing with different reagents showed a creatinine concentration of 0.84 mg/dl. Immunoglobulin (Ig)G was markedly elevated, and creatinine and IgG fluctuated in parallel, suggesting the cause of the pseudohypercreatininemia. IgG4 was also elevated at 844 mg/dl. Immunosuppressive steroid therapy effectively decreased the IgG concentration and resolved the pseudohypercreatininemia. Conclusions: In cases of elevated creatinine concentration with the presence of abnormal proteins, pseudohypercreatininemia should be considered. We report a rare case of pseudohypercreatininemia caused by polyclonal IgG.

    Subcutaneous transplantation aims to enhance the growth and functionality of transplanted cells for therapeutic outcomes in tissue engineering. However, the limited subcutaneous vascular network poses a challenge. Conventional methods involve co-transplantation with endothelial cells or angiogenic scaffold implantation, but they have drawbacks like tissue inflammation, compromised endothelial cell functionality, and the risk of repeated scaffold transplantation. Effective techniques are needed to overcome these challenges. This study explores the potential of G/O-NGD, a gel-in-oil nanogel dispersion, as a transdermal carrier of proliferative factors to promote angiogenesis in subcutaneous graft beds before cell transplantation. We observed robust subcutaneous angiogenesis by delivering varying amounts of bFGF using the G/O-NGD emulsion. Quantitative analysis of several parameters confirmed the efficacy of this method for building a subcutaneous vascular network. G/O-NGD is a biodegradable material that facilitates localized transdermal delivery of bFGF while maintaining its activity. The findings of this study have significant implications in both medical and industrial fields.

    Aim: The noninvasive tests (NITs) Agile 3+ and Agile 4 effectively identify patients with nonalcoholic fatty liver disease (NAFLD) complicated with advanced fibrosis (F3–4) and cirrhosis (F4), respectively. Little information is available on associations between Agile scores and intra-/extrahepatic events. The aim of this study was to determine the predictive performance of Agile scores for intra-/extrahepatic events in Asian patients with biopsy-proven NAFLD. Methods: We undertook a retrospective multicenter cohort study to investigate associations between intra-/extrahepatic events and two Agile scores, Agile 3+ and Agile 4. The scores were obtained by combining clinical parameters and liver stiffness measurement using transient elastography. Results: Among 403 enrolled patients, 11 had liver-related events (LREs), including seven with hepatocellular carcinoma (HCC). The incidence of LREs and HCC showed a stepwise increase in the advanced fibrosis group (F3–4), Agile 3+ rule-in (F3–4, highly suspected), and Agile 4 rule-in (F4, highly suspected) groups, compared to their counterparts. Hazard ratios for LREs in the advanced fibrosis group, Agile 3+ rule-in, and Agile 4 rule-in groups were 4.05 (p = 0.03), 23.5 (p = 0.003), and 45.5 (p < 0.001), respectively. The predictive performance results for Agile 3+ and Agile 4 were 0.780 and 0.866, respectively, which were higher than for fibrosis (0.595). Unlike for LREs, Agile scores failed to identify patients with extrahepatic events, including cardiovascular events and extrahepatic cancer. Conclusions: Agile 3+ and Agile 4 scores are excellent NITs for predicting LREs in patients with NAFLD, possibly without histological assessment.

    Adenocarcinoma, not otherwise specified (NOS) is a heterogenous group of salivary gland tumors that likely contains distinct tumors that have not yet been characterized. Indeed, in recent years, cases previously diagnosed as adenocarcinoma, NOS have been recategorized into novel tumor designations such as secretory carcinoma, microsecretory adenocarcinoma, and sclerosing microcystic adenocarcinoma. We sought to describe a distinctive, hitherto-undescribed salivary gland tumor encountered in the authors' practices. Cases were pulled from the surgical pathology archives of the authors' institutions. Histologic, immunohistochemical, and clinical findings were tabulated, and targeted next-generation sequencing was performed on all cases. Nine cases were identified, arising in 8 women and 1 man ranging from 45 to 74 years (mean, 56.7 y). Seven tumors (78%) arose in the sublingual gland, while 2 (22%) arose in the submandibular gland. The cases shared a distinctive morphologic appearance. They were biphasic, with ducts scattered among a predominant polygonal cell with round nuclei, prominent nucleoli, and pale eosinophilic cytoplasm. These cells were arranged as trabeculae and palisaded as pseudorosettes around hyalinized stroma and vessels, resembling a neuroendocrine tumor. Four of the cases were well-circumscribed, while the remaining 5 showed infiltrative growth including perineural invasion in 2 (22%) and lymphovascular invasion in 1 (11%). Mitotic rates were low (mean, 2.2/10 HPFs); necrosis was absent. By immunohistochemistry, the predominant cell type was strongly positive for CD56 (9 of 9) and variably positive for pan-cytokeratin (AE1/AE3) (7 of 9) with patchy S100 (4 of 9), but negative for synaptophysin (0 of 9) and chromogranin (0 of 9), while the ducts were strongly positive for pan-cytokeratin (AE1/AE3) (9 of 9) and CK5/6 (7 of 7). Next-generation sequencing did not reveal any fusions or obvious driver mutations. All cases were resected surgically, with external beam radiation also done in 1 case. Follow-up was available in 8 cases; there were no metastases or recurrences after 4 to 160 months (mean, 53.1 mo). A dual population of scattered ducts with a predominance of CD56-positive neuroendocrine-like cells characterizes a unique salivary gland tumor which is often encountered in the sublingual glands of women, for which we propose the term "palisading adenocarcinoma." Although the tumor was biphasic and had a neuroendocrine-like appearance, it lacked convincing immunohistochemical evidence of myoepithelial or neuroendocrine differentiation. Although a subset showed unequivocally invasive growth, this tumor appears to behave in an indolent manner. Moving forward, recognition of palisading adenocarcinoma and its separation from other salivary adenocarcinomas, NOS will facilitate a better understanding of the characteristics of this previously unrecognized tumor.

    Background and Aims: Both fibrosis status and body weight are important for assessing prognosis in nonalcoholic fatty liver disease (NAFLD). The aim of this study was to identify population clusters for specific clinical outcomes based on fibrosis-4 (FIB-4) index and body mass index (BMI) using an unsupervised machine learning method. Methods: We conducted a multicenter study of 1335 biopsy-proven NAFLD patients from Japan. Using the Gaussian mixture model to divide the cohort into clusters based on FIB-4 index and BMI, we investigated prognosis for these clusters. Results: The cohort consisted of 223 cases (16.0%) with advanced fibrosis (F3–4) as assessed from liver biopsy. Median values of BMI and FIB-4 index were 27.3 kg/m2 and 1.67. The patients were divided into four clusters by Bayesian information criterion, and all-cause mortality was highest in cluster d, followed by cluster b (P = 0.001). Regarding the characteristics of each cluster, clusters d and b presented a high FIB-4 index (median 5.23 and 2.23), cluster a presented the lowest FIB-4 index (median 0.78), and cluster c was associated with moderate FIB-4 level (median 1.30) and highest BMI (median 34.3 kg/m2). Clusters a and c had lower mortality rates than clusters b and d. However, all-cause of death in clusters a and c was unrelated to liver disease. Conclusions: Our clustering approach found that the FIB-4 index is an important predictor of mortality in NAFLD patients regardless of BMI. Additionally, non-liver-related diseases were identified as the causes of death in NAFLD patients with low FIB-4 index.

    Background: Multicystic biliary hamartoma (MCBH) is an extremely rare benign liver lesion characterized by a gross well-circumscribed multicystic honeycomb appearance. This report presents a MCBH case with a marked peribiliary gland component which showed unusual histology. Case Presentation: A 63-year-old Japanese male was admitted to our hospital for a detailed examination of a hepatic cystic lesion, which was originally detected 14 years ago and had slowly enlarged. A preoperative imaging study revealed a well-demarcated multicystic lesion without communication to the biliary tracts. The possible clinical diagnoses were mucinous cystic neoplasm (MCN) or MCBH. The lesion was successfully resected by purely laparoscopic right anterior sectionectomy. The cut surfaces of resected specimens grossly exhibited a well-circumscribed multicystic lesion with a thick septum. Histologically, the cyst wall was covered by cuboidal epithelial cells resembling epithelium of the bile duct while abundant small ducts, which morphologically resembled peribiliary glands, were observed among the fibrous stroma of the thick septum. Although possible pathological diagnosis varied, including intrahepatic cholangiocarcinoma, intraductal papillary neoplasm of the bile duct, biliary adenofibroma, MCN and MCBH, the lesion was finally diagnosed as MCBH with a marked peribiliary gland component. Conclusions: MCBH can contain abundant peribiliary glands in the fibrous stroma. A pathologist should be careful not to diagnose such peribiliary glands in MCBH as neoplastic glands.

    Background: Clinical trials enroll patients with active fibrotic nonalcoholic steatohepatitis (NASH) (nonalcoholic fatty liver disease [NAFLD] activity score ≥ 4) and significant fibrosis (F ≥ 2); however, screening failure rates are high following biopsy. We developed new scores to identify active fibrotic NASH using FibroScan and magnetic resonance imaging (MRI). Methods: We undertook prospective primary (n = 176), retrospective validation (n = 169), and University of California San Diego (UCSD; n = 234) studies of liver biopsy-proven NAFLD. Liver stiffness measurement (LSM) using FibroScan or magnetic resonance elastography (MRE), controlled attenuation parameter (CAP), or proton density fat fraction (PDFF), and aspartate aminotransferase (AST) were combined to develop a two-step strategy—FibroScan-based LSM followed by CAP with AST (F-CAST) and MRE-based LSM followed by PDFF with AST (M-PAST)—and compared with FibroScan-AST (FAST) and MRI-AST (MAST) for diagnosing active fibrotic NASH. Each model was categorized using rule-in and rule-out criteria. Results: Areas under receiver operating characteristic curves (AUROCs) of F-CAST (0.826) and M-PAST (0.832) were significantly higher than those of FAST (0.744, p = 0.004) and MAST (0.710, p < 0.001). Following the rule-in criteria, positive predictive values of F-CAST (81.8%) and M-PAST (81.8%) were higher than those of FAST (73.5%) and MAST (70.0%). Following the rule-out criteria, negative predictive values of F-CAST (90.5%) and M-PAST (90.9%) were higher than those of FAST (84.0%) and MAST (73.9%). In the validation and UCSD cohorts, AUROCs did not differ significantly between F-CAST and FAST, but M-PAST had a higher diagnostic performance than MAST. Conclusions: The two-step strategy, especially M-PAST, showed reliability of rule-in/-out for active fibrotic NASH, with better predictive performance compared with MAST. This study is registered with ClinicalTrials.gov (number, UMIN000012757).

    Background and Aims: This study aimed to histologically validate atrial structural remodelling associated with atrial fibrillation. Methods and results: Patients undergoing atrial fibrillation ablation and endomyocardial atrial biopsy were included (n = 230; 67 ± 12 years old; 69 women). Electroanatomic mapping was performed during right atrial pacing. Voltage at the biopsy site (Vbiopsy), global left atrial voltage (VGLA), and the proportion of points with fractionated electrograms defined as ≥5 deflections in each electrogram (%Fractionated EGM) were evaluated. SCZtotal was calculated as the total width of slow conduction zones, defined as regions with a conduction velocity of <30 cm/s. Histological factors potentially associated with electroanatomic characteristics were evaluated using multiple linear regression analyses. Ultrastructural features and immune cell infiltration were evaluated by electron microscopy and immunohistochemical staining in 33 and 60 patients, respectively. Fibrosis, intercellular space, myofibrillar loss, and myocardial nuclear density were significantly associated with Vbiopsy (P =. 014, P <. 001, P <. 001, and P =. 002, respectively) and VGLA (P =. 010, P <. 001, P =. 001, and P <. 001, respectively). The intercellular space was associated with the %Fractionated EGM (P =. 001). Fibrosis, intercellular space, and myofibrillar loss were associated with SCZtotal (P =. 028, P <. 001, and P =. 015, respectively). Electron microscopy confirmed plasma components and immature collagen fibrils in the increased intercellular space and myofilament lysis in cardiomyocytes, depending on myofibrillar loss. Among the histological factors, the severity of myofibrillar loss was associated with an increase in macrophage infiltration. Conclusion: Histological correlates of atrial structural remodelling were fibrosis, increased intercellular space, myofibrillar loss, and decreased nuclear density. Each histological component was defined using electron microscopy and immunohistochemistry studies.

    Objective: Liver stiffness measurements (LSMs) and controlled attenuation parameters (CAPs) obtained using vibration-controlled transient elastography (VCTE) are recognized non-invasive methods of assessing liver histology. The usefulness of CAP for predicting liver-related events (LREs: hepatocellular carcinoma, decompensation, bleeding varices) is not well understood worldwide. Our aim was to re-evaluate the cutoff values of LSM/CAP in Japan and to examine whether LSM/CAP can predict LRE. Methods: Japanese NAFLD patients (n = 403) who underwent both liver biopsy and VCTE were enrolled. We determined optimal cutoff values of LSM/CAP diagnoses for fibrosis stage and steatosis grade and investigated their clinical outcome based on LSM/CAP values. Results: The LSM cutoff values for F1 to F4 are 7.1, 7.9, 10.0 and 20.2 kPa, and the CAP cutoff values for S1 to S3 are 230, 282 and 320 dB/m. During a median follow-up of 2.7 y (range: 0.0–12.5 y), 11 patients developed LREs. The incidence of LREs in the LSM Hi (≥8.7) group was significantly higher than that in the LSM Lo (<8.7) group (p = 0.003), and the incidence in the CAP Lo (<295) group was higher than that in CAP Hi (≥295) group (p = 0.018). Considering LSM and CAP together, the risk of LRE was higher in the LSM Hi CAP Lo group than in the LSM Hi CAP Hi group (p = 0.03). Conclusion: We set LSM/CAP cutoff values to diagnose liver fibrosis and steatosis in Japan. Our study determined that NAFLD patients with high LSM and low CAP values are at high risk for LREs.

    Background and Aims: Noninvasive tests (NITs) have prognostic potential, but whether NITs are comparable with liver biopsy is unclear. This study aimed to examine the prognostic accuracy of NITs for liver-related mortality (LRM) and events (LREs) in patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD). Methods: We investigated 1313 patients with NAFLD. Patients were assigned to low-risk, indeterminate-risk, and high-risk groups using conventional cutoff values of each FIB-4 and NAFLD fibrosis score (NFS) and to stage 0–2 and stage 3–4 groups using the fibrosis stage. Survival and Cox regression analyses of the prognostic potential of NITs for LRM/LREs were conducted. Results: During a median follow-up of 4.5 years, regarding to FIB-4, the incidence rate (/1000 person-years) in the low risk was zero for LRM and 0.5 for LREs. In contrast, the rate in stage 0–2 was 1.3 for LRM and 2.8 for LRE. The adjusted hazard ratios (aHRs) for LREs in the high risk compared with the low risk were 32.85 (P < 0.01). The aHRs in stage 3–4 compared with stage 0–2 were 2.68 (P = 0.02) for LREs and 2.26 (P = 0.582) for LRM. In the same fibrosis stage, the incidence of LRM/LREs was more frequent with a higher risk stratification. The same trend was observed for NFS. Conclusions: NITs accurately predict LRM and LREs as well as a liver biopsy in Japanese patients with NAFLD. Patients in the low risk may not require close follow-up for at least 5 years. The simple NITs could be an acceptable alternative method to performing a liver biopsy for the prognosis of NAFLD.

    Aim: Agile 3+ and Agile 4 scores, based on liver stiffness measurement (LSM) by transient elastography and clinical parameters, were recently reported to be effective in identifying advanced fibrosis and cirrhosis in nonalcoholic fatty liver disease (NAFLD). This study aimed to validate the utility of these scores in Japanese patients with NAFLD. Methods: Six hundred forty-one patients with biopsy-proven NAFLD were analyzed. The severity of liver fibrosis was pathologically evaluated by one expert pathologist. The LSM, age, sex, diabetes status, platelet count, and aspartate aminotransferase and alanine aminotransferase levels were used to calculate Agile 3+ scores, and the parameters above excluding age were used for Agile 4 scores. The diagnostic performance of the two scores was evaluated using receiver operating characteristic (ROC) curve analysis. Sensitivity, specificity, and predictive values of the original low cut-off (for rule-out) value and high cut-off (for rule-in) value were tested. Results: For diagnosis of fibrosis stage ≥3, the area under the ROC (AUROC) was 0.886, and the sensitivity of the low cut-off value and the specificity of the high cut-off value were 95.3% and 73.4%, respectively. For diagnosis of fibrosis stage 4, AUROC, the sensitivity of the low cut-off value, and the specificity of the high cut-off value were 0.930, 100%, and 86.5%, respectively. Both scores had higher diagnostic performance than the FIB-4 index and the enhanced liver fibrosis score. Conclusions: Agile 3+ and Agile 4 are reliable noninvasive tests to identify advanced fibrosis and cirrhosis in Japanese NAFLD patients with adequate diagnostic performance.

    The relationship between baseline serum albumin level and long-term prognosis of patients with nonalcoholic fatty liver disease (NAFLD) remains unknown. This is a sub-analysis of the CLIONE (Clinical Outcome Nonalcoholic Fatty Liver Disease) study. The main outcomes were: death or orthotopic liver transplantation (OLT), liver-related death, and liver-related events (hepatocellular carcinoma [HCC], decompensated cirrhosis, and gastroesophageal varices/bleeding). 1383 Japanese patients with biopsy-confirmed NAFLD were analyzed. They were divided into 3 groups based on serum albumin: high (>4.0 g/dL), intermediate (3.5–4.0 g/dL), and low (<3.5 g/dL). Unadjusted hazard ratio [HR] of the intermediate albumin group, compared with the high albumin group, were 3.6 for death or OLT, 11.2 for liver-related death, 4.6 for HCC, 8.2 for decompensated cirrhosis, and 6.2 for gastroesophageal varices (all risks were statistically significant). After adjusting confounding factors, albumin remained significantly associated with death or OLT (intermediate vs. high albumin group: HR 3.06, 95% confidence interval [CI] 1.59–5.91, p < 0.001; low vs. high albumin group: HR 22.9, 95% CI 8.21–63.9, p < 0.001). Among biopsy-confirmed NAFLD patients, those with intermediate or low serum albumin had a significantly higher risk of death or OLT than those with high serum albumin.

    Aim: Impacts of platelet counts at the time of liver biopsy on hepatocellular carcinoma (HCC) development in patients with nonalcoholic fatty liver disease (NAFLD) remain unknown. The aim of this study was to investigate the prognostic value of platelet counts in patients with biopsy-confirmed NAFLD using data from a multicenter study. Methods: One thousand three hundred ninety-eight patients were included in this subanalysis of the CLIONE (Clinical Outcome Nonalcoholic Fatty Liver Disease) in Asia study. Liver biopsy specimens were pathologically diagnosed, and histologically scored using the NASH Clinical Research Network system. Demographic, clinical, laboratory, and pathological data were collected. Results: During a median follow-up period of 4.6 years (range, 0.3–21.6 years), which corresponds to 8874 person-years, 37 patients developed HCC. Using a cut-off baseline platelet count of 192 × 109/L, the lower platelet group had a higher HCC rate than the higher platelet group (6.7% vs. 0.4%; p < 0.001). This cut-off value significantly stratified the event-free rate for HCC. Lower platelet counts were associated with an increased risk of HCC development. Relative to patients with platelet counts of 192 × 109/L, patients with platelet counts of 100 × 109/L had an unadjusted hazard ratio (HR) for HCC development of 7.37 (95% confidence interval [CI], 3.81–14.2) and an adjusted HR of 11.2 (95% CI, 3.81–32.7; p < 0.001), adjusting for age, sex, NASH, and diabetes. Conclusions: Baseline platelet counts of 192 × 109/L and lower are associated with a higher risk of developing HCC in patients with biopsy-confirmed NAFLD and require active surveillance.

    Injuries to the nervous system account for the widespread morbidity, mortality, and discomfort worldwide. Artificial nerve guidance conduits (NGCs) offer a promising platform for nerve reconstruction, however, they require extracellular matrix (ECM)-like features to better mimic the in vivo microenvironment. Consequently, this research was aimed to fabricate heparin/growth factors (GFs)-immobilized artificial NGCs. Heparin was covalently immobilized onto aligned electrospun polycaprolactone/gelatin (PCL/Gel) nanofibers. Thereafter, basic fibroblast growth factor (bFGF) and nerve growth factor (NGF) were preferentially immobilized on heparinized nanofibers; the immobilization efficiency of GFs was found to be 50% with respect to (w.r.t.) their initial loaded amounts. The in vivo implantation of NGCs in a sciatic nerve defect model revealed the successful retention (~ 10% w.r.t the initial loaded amount) and bioactivity of NGF for up to 5 days. The permeability of bovine serum albumin (BSA) from nanofibrous membranes was further assessed and found to be comparable with the commercialized cellulose acetate membranes. The bioactivity of NGCs was assessed in a sciatic nerve defect model in rats for short-term (1 week) and long-term (1-month). The NGCs displayed good structural stability and biocompatibility in vivo. The in vivo evaluation revealed the accumulation of host cells into the transplanted NGCs. Taken together; these heparin/GFs-immobilized artificial NGCs may have broad implications for nerve regeneration and related tissue engineering disciplines.

    Aim: The enhanced liver fibrosis (ELF) test is a noninvasive method for diagnosing hepatic fibrosis in patients with nonalcoholic fatty liver disease (NAFLD). This multicenter cohort study aimed to evaluate the accuracy of the ELF test and compare it with other noninvasive tests in Japan. Methods: We analyzed 371 Japanese patients with biopsy-proven NAFLD. We constructed area under the receiver operator characteristic curves (AUROC) to determine the diagnostic accuracies of the ELF test, the Mac-2-binding protein glycosylation isomer (M2BPGi), the Fibrosis-4 (FIB-4) index, and combinations of these indices. Results: In patients with F0/F1/F2/F3/F4 fibrosis, the median values of the ELF test were 8.98/9.56/10.39/10.92/11.41, respectively. The AUROCs of the ELF test for patients with F0 versus F1–4, F0–1 versus F2–4, F0–2 versus F3–4, and F0–3 versus F4 fibrosis were 0.825/0.817/0.802/0.812, respectively. The AUROCs of the ELF test were greater than those of the FIB-4 index and M2BPGi at each fibrosis stage. Respective low and high cut-off values yielded sensitivities and specificities for predicting advanced fibrosis (≥F3) of 91.1% and 50.8%, and 38.5% and 92.8%, respectively. For F3 or F4 fibrosis, the combined values from the ELF test and FIB-4 index showed a sensitivity of 98.5%, and the combined values from the ELF test and M2BPGi assay showed a specificity of 97.5%. Conclusions: In Japan, the ELF test predicts NAFLD-related fibrosis from its early stages. The diagnostic ability of the ELF test was not inferior to that of other indices, and the combined values of ELF plus other indices were more accurate.

    Skin regeneration is hindered by poor vascularization, prolonged inflammation, and excessive scar tissue formation, which necessitate newer strategies to simultaneously induce blood vessel regeneration, resolve inflammation, and induce host cell recruitment. Concurrent deployment of multiple biological cues to realize synergistic reparative effects may be an enticing avenue for wound healing. Herein, we simultaneously deployed SDF (stromal cell-derived factor)− 1α, VEGF (vascular endothelial growth factor)-binding peptide (BP), and GLP (glucagon like peptide)− 1 analog, liraglutide (LG) in core/shell poly(L-lactide-co-glycolide)/gelatin fibers to harness their synergistic effects for skin repair in healthy as well as diabetic wound models in rats. Microscopic techniques, such as SEM and TEM revealed fibrous and core/shell type morphology of membranes. Boyden chamber assay and scratch-wound assay displayed significant migration of HUVECs (human umbilical vein endothelial cells) in SDF-1α containing fibers. Subcutaneous implantation of membranes revealed higher cellular infiltration in SDF-1α loaded fibers, especially, those which were co-loaded with LG or BP. Implantation of membranes in an excisional wound model in healthy rats further showed significant and rapid wound closure in dual cues loaded groups as compared to control or single cue loaded groups. Similarly, the implantation of dressings in type 2 diabetes rat model revealed fast healing, skin appendages regeneration, and blood vessel regeneration in dual cues loaded fibers (SDF-1α/LG, SDF-1α/BP). Taken together, core/shell type fibers containing bioactive peptides significantly promoted wound repair in healthy as well as diabetic wound models in rats.

    Ultraviolet (UV) radiation from the sun or artificial sources is one of the primary causes of skin damage, including sunburns, tanning, erythema, and skin cancer. Among the three different types of UV rays, UVB rays have a medium wavelength that can penetrate the epidermal layer of the skin, resulting in sunburn, suntan, blistering, and melanoma in case of chronic exposure. This study aimed to evaluate the preventive and therapeutic effects of a gel-in-oil nanogel dispersion (G/O-NGD) as a transdermal delivery biomolecular carrier for skin damage caused by UVB light. The efficacy of this carrier against UVB-induced skin damage was investigated in vivo by delivering different growth factors (GFs) encapsulated in a G/O-NGD. Artificial UVB light was used to induce skin damage in nude mice, followed by the transdermal application of five GF [vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), epidermal growth factor (EGF), transforming growth factor (TGF)-1, and insulin-like growth factor (IGF)-α]-immobilized G/O-NGD. Among these GFs, VEGF and bFGF promoted angiogenesis, while EGF, TGF-1, and IGF-α promoted the repair and regeneration of damaged cells. The results showed that G/O-NGD was superior to heparin-immobilized G/O-NGD in reducing UVB-induced skin damage, such as erythema, epidermal water reduction, inflammation, and dermis thickening. In addition, G/O-NGD could prevent and treat abnormal follicle proliferation caused by UVB rays and exhibited potential to repair lipid glands. Overall, our results demonstrate the potential of G/O-NGDs for the treatment of UVB-induced skin damage.

    Background & Aims: There are no detailed reports of clinical outcomes in Asian patients with nonalcoholic fatty liver disease (NAFLD) who undergo liver biopsy. We aimed to investigate the clinical outcomes of a large cohort of Asian patients with biopsy-proven NAFLD and evaluate the specific effects of nonalcoholic steatohepatitis and fibrosis stage. Methods: This multicenter registry-based retrospective cohort study, called the CLIONE (Clinical Outcome Nonalcoholic Fatty Liver Disease) in Asia, included 1398 patients. Results: The median follow-up period was 4.6 years (range, 0.3–21.6 years), representing a total of 8874 person-years of follow-up. During that time, 47 patients died, and 1 patient underwent orthotopic liver transplantation. The leading cause of death was nonhepatic cancer (n = 10). The leading causes of liver-related death were liver failure (n = 9), hepatocellular carcinoma (HCC) (n = 8), and cholangiocellular carcinoma (n = 4). During follow-up, 37 patients developed HCC, 31 developed cardiovascular disease, and 68 developed nonhepatic cancer (mainly breast, stomach, and colon/rectum). Among our cohort of patients with NAFLD, liver-specific mortality was 2.34/1000 person-years (95% confidence interval [CI], 1.52–3.58), overall mortality was 5.34/1000 person-years (95% CI, 4.02–7.08), and HCC incidence was 4.17/1000 person-years (95% CI, 3.02–5.75). Liver fibrosis was independently associated with liver-related events but not overall mortality. Conclusions: Liver-related mortality was the leading cause of mortality in Asian patients with biopsy-confirmed NAFLD. Although fibrosis stage was independently associated with liver-related events, it was not associated with overall mortality after adjusting for confounders, such as histologic features of steatohepatitis.

    Purpose: To assess the dependency of the Time to enhancement (TTE) of breast lesions and normal breast parenchyma from menopausal status and menstrual cycle using ultrafast compressed sensing (CS) -accelerated dynamic contrast-enhanced (DCE) MRI. Methods: This institutional review board approved retrospective study included 89 breast cancers, 22 benign lesions and 131 normal breast parenchymal foci. A prototypical ultrafast DCE sequence obtained 30 phases with 2.9 s temporal resolution. Mean and median TTE of all breast cancers, benign lesions and normal breast parenchymal foci were assessed. we also assessed whether there were any differences in TTE regarding the menopausal status and menstrual cycle. Results: The TTE of breast cancer was significantly shorter than that of benign lesions and normal breast parenchymal foci in both the premenopausal status (5.8 vs. 8.7 and 8.7 s, respectively) (p = 0.0028 and < 0.0001, respectively) and postmenopausal status (5.8 vs. 11.6 and 11.6 s, respectively) (p < 0.0001 in both). The TTE of parenchymal foci in the premenopausal status was significantly shorter than that in the postmenopausal status (p = 0.0025). Although the TTE interval between cancer and parenchymal foci in premenopausal status is shorter than that in postmenopausal status, the AUCs in the pre- and postmenopausal status for differentiating breast cancer and parenchymal foci were comparable with using different cutoff TTE values. There were no differences in TTE regarding the menstrual cycle. Conclusions: The TTE derived from ultrafast CS-accelerated DCE MRI was useful to differentiate breast cancer from benign lesions and normal breast parenchymal foci in both pre- and postmenopausal status.

    Background and Aims: Nonalcoholic fatty liver diseases (NAFLD) and nonalcoholic steatohepatitis (NASH) can cause hepatocellular carcinoma (HCC). We examined histological features and reported noninvasive markers/models for stratifying the risk of HCC development in patients with biopsy-proven NAFLD or NASH. Methods: A total of 1389 patients who had a histological diagnosis of NAFLD or NASH based on liver biopsy and underwent regular surveillance for HCC were included. The ability to predict HCC development was compared between histological features including liver fibrosis and NAFLD activity score, and noninvasive markers/models including aMAP (age, male, albumin–bilirubin, and platelet) score, FIB-4 (Fibrosis-4) index, and ALBI (albumin-bilirubin) score calculated at the time of biopsy. Results: The C index of aMAP score was 0.887, which was consistent with the original report, comparable to FIB-4 index (0.878), and higher than those of ALBI score (0.789), histological liver fibrosis (0.723), and NAFLD activity score (0.589). The hazard ratios for HCC development in the aMAP intermediate and high-risk groups were 21.0 (95% confidence interval [CI], 3.6–402.0) and 110.3 (95% CI, 16.3–2251.4), respectively, in comparison to the aMAP score low-risk group. Those in the FIB-4 index moderate- and high-fibrosis groups were 10.3 (95% CI, 1.7–199.8) and 93.1 (95% CI, 16.3–1773.8), respectively, in comparison to the FIB-4 index mild-fibrosis group. No patients in the aMAP score low-risk group developed HCC during the study period. Conclusion: For stratifying the risk of HCC development in patients with biopsy-proven NAFLD or NASH, both aMAP score and FIB-4 index showed high discriminative ability as noninvasive markers, which were superior histological features.

    Background: Anaplastic lymphoma kinase rearrangement-associated renal cell carcinoma (ALK-RCC) is an extremely rare tumor and ALK-RCC that mimics mucinous tubular and spindle cell carcinoma (MTSCC) has been very reported only in one instance. Case presentation: A 42-year-old Japanese woman was admitted to our hospital for the treatment of a left renal tumor measuring 5 cm in maximum dimension. She underwent a laparoscopic left nephrectomy. Histologically, the tumor formed tubular or focally papillary structures with a small amount of spindle-shaped tumor cells against the background of prominent extracellular mucin. Although the tumor cells were negative for immunohistochemistry (IHC) of alpha-methylacyl-CoA racemase (AMACR) and lymph node metastasis was presented (these are atypical findings for MTSCC), we initially diagnosed the tumor as MTSCC based on its morphological characteristics with mucin deposition. However, an additional IHC analysis revealed that the tumor cells were diffusely positive for ALK-IHC. In addition, TPM3 exon 8 – ALK exon 20 fusion gene was detected by RNA sequencing. The tumor was thus correctly diagnosed as ALK rearrangement-associated renal cell carcinoma (ALK-RCC). Conclusions: Since the use of molecular targeted therapy with an ALK inhibitor for ALK-RCC is promising, the correct pathological diagnosis of ALK-RCC is quite important. We strongly recommend that ALK-IHC be routinely performed for renal tumors with negative AMACR staining that mimic MTSCC.

    GPI anchorless prion diseases (GPIALPs) show numerous coarse prion protein (PrP) deposits in the CNS but neuropil spongiform changes are mild and the incidence of dementia is low. Here, we examined differences in resident microglial phenotypes between GPIALP (D178fs25) and the other prion diseases Gerstmann-Sträussler-Scheinker (GSS) disease and sporadic Creutzfeldt-Jakob disease (sCJD) with respect to homeostasis and activation. Immunohistochemistry was performed on 2 GPIALP (D178fs25), 4 GSS (P102L), and 4 sCJD cases. Homeostatic microglia expressing TMEM119 and P2RY12 were preserved in GPIALP compared to GSS and sCJD. Microglia/macrophage activation in GSS and sCJD was associated with the extent of spongiform change. Immunoelectron microscopy revealed TMEM119 and P2RY12 in PrP plaque cores. Activated microglia/macrophages expressing HLA-DR and CD68 were predominant in GSS and sCJD whereas in GPIALP, homeostatic microglia were retained and activated microglia/macrophages were rarely observed. These data suggest that PrP deposition in GPIALP is less toxic and that microglia may be immune-tolerant to PrP deposition. This may be associated with milder tissue damage and a low incidence of dementia. Whereas microglia/macrophage activation is considered to be a reaction to tissue injury, this study shows that the degree of microglia/macrophage activity might influence the extent of tissue damage.

    Background and Aim: Older age, type 2 diabetes mellitus (T2DM), and obesity are known risk factors for liver-related events (LREs). We investigated the impacts of T2DM and obesity on LRE according to age in Japanese patients with non-alcoholic fatty liver disease (NAFLD). Methods: We performed a subanalysis of a retrospective cohort study (CLIONE in Asia), including 1395 patients with biopsy-proven NAFLD. The median follow-up was 4.6 years. Results: The median age was 57 years, and 36.2% had T2DM. The median body mass index (BMI) was 27.4, and 28.5% were severely obese (BMI ≥ 30). During follow-up, 37 patients developed hepatocellular carcinoma (HCC), and 58 patients developed LRE. In patients younger than 65 years, advanced fibrosis (hazard ratio [HR] 7.69, P < 0.001) and T2DM (HR 3.37, P = 0.017) were HCC risk factors, and advanced fibrosis (HR 9.40, P < 0.001) and T2DM (HR 2.51, P = 0.016) were LRE risk factors. In patients 65 years and older, advanced fibrosis (HR 4.24, P = 0.010) and obesity (HR 4.60, P = 0.006) were HCC risk factors, and advanced fibrosis (HR 4.22, P = 0.002) and obesity (HR 4.22, P = 0.002) were LRE risk factors. Conclusion: Type 2 diabetes mellitus and obesity contributed to LRE in younger and older patients, respectively, along with advanced fibrosis. Therefore, controlling T2DM in patients younger than 65 years and controlling weight in patients 65 years and older could prevent LRE. The development of age-dependent screening and management strategies is necessary for patients with NAFLD.

    Purpose: Pancreatic undifferentiated carcinoma (UDC) is a rare tumor with a worse prognosis than pancreatic ductal adenocarcinoma (PDAC). Recent study showed that UDC exhibits loss of SMARCB1, which is one of the subunits of the SWI/SNF complex. However, whether there are abnormalities of other SWI/SNF complex subunits in UDC has remained unknown. In this study, we attempted to clarify whether the loss of SWI/SNF complex subunits is related to the pathogenesis of UDC by comparing undifferentiated component (UC) and ductal adenocarcinoma component (DAC). Methods: Genetic analysis of the ten UCs and six DACs was performed. The expression of ARID1A, SMARCA2, SMARCA4, SMARCB1, SMARCC1, and SMARCC2 in formalin-fixed, paraffin-embedded tumor tissues collected by surgical resection from 18 UDC patients was evaluated immunohistochemically. Moreover, two pancreatic cell lines were evaluated for the effects of siARID1A on the mRNA and protein expression of E-cadherin, vimentin, and epithelial-mesenchymal transition (EMT)-related markers by qRT-PCR, western blotting, and immunofluorescence staining. Results: UCs tended to have a higher frequency of mutation in ARID1A, SMARCA4, and SMARCC2 than DACs. Immunohistochemically, UCs revealed reduced/lost expression of ARID1A (72%), SMARCB1 (44%), SMARCC1 (31%), and SMARCC2 (67%). Reduced/lost expression of ARID1A, SMARCB1, and SMARCC2 was significantly more frequently observed in UCs than in DACs. In the pancreatic cell lines, western blotting and qRT-PCR showed that the downregulation of ARID1A increased the expression of vimentin and EMT-related markers. Conclusion: Our results suggest that the abnormality of SWI/SNF complex subunits, especially ARID1A, is one of the factors behind the morphological change of UDC.

    The differential effects of sporadic Creutzfeldt-Jakob disease (sCJD) on the hippocampus and other neocortical areas are poorly understood. We aimed to reveal the histological patterns of cellular prion protein (PrPC) and abnormal prion protein (PrPSc) in hippocampi of sCJD patients and normal controls (NCs). Our study examined 18 postmortem sCJD patients (MM1, 14 cases; MM1 + 2c, 3 cases; MM1 + 2t, 1 case) and 12 NCs. Immunohistochemistry was conducted using 4 primary antibodies, of which 3 targeted the N-terminus of the prion protein (PrP), and 1 (EP1802Y) targeted the C-terminal domain. PrPC expression was abundant in the hippocampus of NCs, and the distribution of PrPC at CA3/4 was reminiscent of synaptic complexes. In sCJD cases with a disease history of <2 years, antibodies against the N-terminus could not detect synapse-like PrP expression at CA4; however, EP1802Y could characterize the synapse-like expression. PrPSc accumulation and spongiform changes became evident after 2 years of illness, when PrPSc deposits were more noticeably detected by N-terminal-specific antibodies. Our findings highlighted the chronology of histopathological alterations in the CA4 region in sCJD patients.

    Background and Aim: Non-alcoholic fatty liver disease (NAFLD) can progress in non-obese patients as in obese patients. Reports on long-term prognosis in non-obese NAFLD patients are controversial. Therefore, we aimed to examine the long-term prognosis of non-obese patients with NAFLD. Methods: This single-center, retrospective cohort study enrolled biopsy-proven non-obese and obese NAFLD patients between January 2002 and December 2011 and followed them up until 31 March 2021, for death and clinical events (cardiovascular and liver-related events and extrahepatic cancers). Results: Of the 223 NAFLD patients, 58 (26.0%) were non-obese. Compared with obese patients, they had a lower fibrosis stage (0.8 ± 0.80 vs 1.2 ± 0.91; P = 0.004), milder lobular inflammation (0.9 ± 0.7 vs 1.1 ± 0.7; P = 0.02), and significantly lower serum creatinine, total bilirubin, ferritin, and type IV collagen 7S and higher high-density lipoprotein levels. After a median follow-up of 8.9 years, no significant difference was noted in mortality between the two groups (2 [3.4%] non-obese vs 5 [3.0%] obese; log-rank test, P = 0.63). Twelve patients (20.7%) in the non-obese group and 32 (19.4%) in the obese group had clinical events. Although the obese group had a higher incidence of clinical events during the first 10 years of follow-up, the non-obese group had a higher incidence after that (log-rank test, P = 0.67). The non-obese group had a high incidence of malignancy (9 [15.5%] non-obese vs 14 [8.3%] obese; P = 0.13). Conclusion: Non-obese NAFLD does not necessarily have a good prognosis, and some cases have a poor prognosis such as extrahepatic cancers. Further validation is required in the future.

    Objectives This study aimed to establish a reliable and reproducible categorized diagnostic classification system with identification of key features to achieve accurate pathological diagnosis of endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNAB) samples of pancreatic lesions. Methods Twelve pathologists examined virtual whole-slide images of EUS-FNAB samples obtained from 80 patients according to proposed diagnostic categories and key features for diagnosis. Fleiss κ was used to assess the concordance. Results A hierarchical diagnostic system consisting of the following 6 diagnostic categories was proposed: inadequate, nonneoplasm, indeterminate, ductal carcinoma, nonductal neoplasm, and unclassified neoplasm. Adopting these categories, the average κ value of participants was 0.677 (substantial agreement). Among these categories, ductal carcinoma and nonductal neoplasm showed high κ values of 0.866 and 0.837, respectively, which indicated the almost perfect agreement. Key features identified for diagnosing ductal carcinoma were necrosis in low-power appearance; structural atypia/abnormalities recognized by irregular glandular contours, including cribriform and nonuniform shapes; cellular atypia, including enlarged nuclei, irregular nuclear contours, and foamy gland changes; and haphazard glandular arrangement and stromal desmoplasia. Conclusions The proposed hierarchical diagnostic classification system was proved to be useful for achieving reliable and reproducible diagnosis of EUS-FNAB specimens of pancreatic lesions based on evaluated histological features.

    Objectives: Weight loss improves the liver pathophysiological status of nonalcoholic fatty liver disease (NAFLD) patients. However, there are few studies that investigate the accurate relationships between nutritional intake and disease progression in NAFLD patients. Methods: A total of 37 biopsy-confirmed NAFLD patients were enrolled in this study. Clinical and nutritional control data of 5074 persons were obtained from the National Institute of Health and Nutrition. Each NAFLD subject recorded dietary intake for seven consecutive days using a dietary questionnaire and photographs of each meal. A dietitian analyzed and quantified the nutritional data in each patient. We further analyzed the nutritional intake of NAFLD patients in three groups according to the following criteria: (1) liver fibrosis degree (advanced, early), (2) gender (male, female), and (3) body mass index (BMI) (high, low). Results: Excesses or deficiencies of multiple nutrients were found in NAFLD patients compared with control subjects. In addition, there were variations in nutritional intake. (1) The intake of vitamins A, B6, and E, pantothenic acid, soluble dietary fiber, and salt was lower in the advanced fibrosis group than in the early fibrosis group. (2) Fat intake was higher in male patients, and dietary fiber intake was lower in both male and female patients compared with control subjects. (3) Saturated fatty acid intake was higher, and copper and vitamin E intakes were lower in patients with high BMI than with low BMI. Conclusions: Our study demonstrates that differences were found in some nutrient intake of NAFLD patients and controls and according to the severity of the conditions (liver fibrosis degree, BMI).

    We compared the preplanned histopathological responses of resected liver metastases from patients who received modified FOLFOX6 plus bevacizumab or modified FOLFOX6 plus cetuximab for liver-limited colorectal metastases in the ATOM trial. Fibrosis and viable tumor cells in tumor regression grade (TRG), infarct-like necrosis in modified TRG (mTRG), and dangerous halo (DH) were assessed. Fifty-five patients (28 and 27 patients in the bevacizumab and cetuximab arms, respectively) were divided into the low (viable tumor cells ≤ 50%) and high (>50%) TRG or mTRG groups. DH was characterized as absent/rare or focal/diffuse. Compared to the bevacizumab arm, the cetuximab arm was more effective, with respect to low TRG (13 vs. 23 patients) and absent/rare DH (14 vs. 19 patients), respectively. Low mTRG was similarly observed in both arms. Low TRG/mTRG and absent/rare DH showed better relapse-free survival (RFS) than high TRG/mTRG and focal/diffuse DH. In the bevacizumab arm, a significant difference in RFS existed between the low and high TRG groups, while in the cetuximab arm, for TRG, mTRG, and DH, the low and absent/rare groups demonstrated significantly longer RFS than the high and focal/diffuse groups, respectively. TRG could estimate RFS in patients who underwent liver metastasectomy after bevacizumab or cetuximab chemotherapy.

    Consultation by subspecialty experts is the most common mode of rendering diagnosis in challenging cases in pathological practice. Our study aimed to highlight the diagnostic benefits of whole-slide image (WSI)-based remote consultation. We obtained diagnostically challenging cases from two institutions from the years 2010 and 2013, with histological diagnoses that contained keywords “probable,” “suggestive,” “suspicious,” “inconclusive,” and “uncertain.” A total of 270 cases were selected for remote consultation using WSIs scanned at 40 ×. The consultation process consisted of three rounds: the first and second rounds each with 12 subspecialty experts and the third round with six multi-expertise senior pathologists. The first consultation yielded 44% concordance, and a change in diagnosis occurred in 56% of cases. The most frequent change was from inconclusive to definite diagnosis (30%), followed by minor discordance (14%), and major discordance (12%). Out of the 70 cases which reached the second round, 31 cases showed discrepancy between the two consultants. For these 31 cases, a consensus diagnosis was provided by six multi-expertise senior pathologists. Combining all WSI-based consultation rounds, the original inconclusive diagnosis was changed in 140 (52%) out of 266 cases. Among these cases, 80 cases (30%) upgraded the inconclusive diagnosis to a definite diagnosis, and 60 cases (22%) changed the diagnosis with major or minor discordance, accounting for 28 cases (10%) and 32 cases (12%), respectively. We observed significant improvement in the pathological diagnosis of difficult cases by remote consultation using WSIs, which can further assist in patient healthcare. A post-study survey highlighted various benefits of WSI-based consults.

    症例は70歳代男性。夜間頻尿を主訴に近医を受診。血液検査でPSA値が11.0ng/mlと高値であり前医紹介となった。前医施行の単純MRIで前立腺に多房性嚢胞性腫瘤を認め、STUMP(stromal tumors of uncertain malignant potential)やcystadenoma、cystadenocarcinomaなどが疑われた。更なる精査、加療目的に当院泌尿器科紹介となった。当院施行の造影MRIでは前立腺背側の両葉で移行域、辺縁域にまたがる48×46×55mmの辺縁分葉状の腫瘤を認めた。内部はT2強調像でやや不均一かつ著明な高信号を呈し、隔壁様の構造が多発していた。T1強調像では大部分は低信号を呈し、腫瘤右側には出血や高粘稠度の液貯留を疑う高信号域を認めた。有意な拡散制限は認めず、dynamic studyでは辺縁優位に漸増性の増強効果を認めた。CTでは腫瘤辺縁にわずかに石灰化を認めた。前立腺生検が施行され、10/10本よりmucinous adenocarcinomaの所見が得られた。他部位に原発巣を示唆する所見はなく、前立腺原発のmucinous adenocarcinomaが強く疑われた。前立腺のmucinous adenocarcinomaは全前立腺癌の0.4%と稀な疾患である。腫瘍内に少なくとも25%以上のムチンを含むと定義されている。今回の症例は手術未施行であるが、全身検索および局所の画像所見からは前立腺原発のmucinous adenocarcinomaとして矛盾しない所見であった。画像所見上の鑑別としてSTUMPやcystadenoma、cystadenocarcinomaなどが挙げられたが、所見によってはこれらとの鑑別は困難となる場合も多い。前立腺のmucinous adenocarcinomaの画像所見についての報告は少なく、今回文献的考察を含めて報告する。(著者抄録)

    INTRODUCTION: No reports on both blood and fecal bile acids (BAs) in patients with nonalcoholic fatty liver disease (NAFLD) exist. We simultaneously assessed the serum and fecal BA patterns in healthy participants and those with NAFLD. METHODS: We collected stool samples from 287 participants from 5 hospitals in Japan (healthy control [HC]: n = 88; mild fibrosis: n = 104; and advanced fibrosis group: n = 95). Blood samples were collected and analyzed for serum BAs and 7α-hydroxy-4-cholesten-3-one (C4)-a surrogate marker for BA synthesis ability-from 141 patients. Concentrations of BAs, including cholic acid (CA), deoxycholic acid (DCA), chenodeoxycholic acid, ursodeoxycholic acid, and lithocholic acid (LCA), were measured using liquid chromatography-mass spectrometry. RESULTS: The total fecal BA concentration was significantly higher in the NAFLD group with worsening of fibrosis than in the HC group. Most of the fecal BAs were secondary and unconjugated. In the fecal BA fraction, CA, DCA, chenodeoxycholic acid, ursodeoxycholic acid, and LCA were significantly higher in the NAFLD than in the HC group. The total serum BA concentration was higher in the NAFLD group with worsening of fibrosis than in the HC group. In the serum BA fraction, CA, LCA, and C4 concentrations were significantly higher in the NAFLD than in the HC group. DISCUSSION: Fecal and serum BA and C4 concentrations were high in patients with NAFLD with worsening of fibrosis, suggesting involvement of abnormal BA metabolism in NAFLD with fibrosis progression. Abnormalities in BA metabolism may be a therapeutic target in NAFLD with fibrosis.

    Background and Aims: Despite that hepatic fibrosis often affects the liver globally, spatial distribution can be heterogeneous. This study aimed to investigate the effect of liver stiffness (LS) heterogeneity on concordance between MR elastography (MRE)-based fibrosis staging and biopsy staging in patients with NAFLD. Approach and Results: We retrospectively evaluated data from 155 NAFLD patients who underwent liver biopsy and 3 Tesla MRE and undertook a retrospective validation study of 169 NAFLD patients at three hepatology centers. Heterogeneity of stiffness was assessed by measuring the range between minimum and maximum MRE-based LS measurement (LSM). Variability of LSM was defined as the stiffness range divided by the maximum stiffness value. The cohort was divided into two groups (homogenous or heterogeneous), according to whether variability was below or above the average for the training cohort. Based on histopathology and receiver operating characteristic (ROC) analysis, optimum LSM thresholds were determined for MRE-based fibrosis staging of stage 4 (4.43, kPa; AUROC, 0.89) and stage ≥3 (3.93, kPa; AUROC, 0.89). In total, 53 had LSM above the threshold for stage 4. Within this group, 30 had a biopsy stage of <4. In 86.7% of these discordant cases, variability of LSM was classified as heterogeneous. In MRE-based LSM stage ≥3, 88.9% of discordant cases were classified as heterogeneous. Results of the validation cohort were similar to those of the training cohort. Conclusions: Discordance between biopsy- and MRE-based fibrosis staging is associated with heterogeneity in LSM, as depicted with MRE.

    There is an association between nonalcoholic fatty liver disease (NAFLD) and atherosclerosis, but the genetic risk of atherosclerosis in NAFLD remains unclear. Here, a single-nucleotide polymorphism (SNP) of the heat shock 70 kDa protein 8 (HSPA8) gene was analyzed in 123 NAFLD patients who had been diagnosed using a liver biopsy, and the NAFLD phenotype including the maximum intima–media thickness (Max-IMT) of the carotid artery was investigated. Patients with the minor allele (A/G or G/G) of rs2236659 showed a lower serum heat shock cognate 71 kDa protein concentration than those with the major A/A allele. Compared with the patients with the major allele, those with the minor allele showed a higher prevalence of hypertension and higher Max-IMT in men. No significant associations between the HSPA8 genotype and hepatic pathological findings were identified. In decision-tree analysis, age, sex, liver fibrosis, and HSPA8 genotype were individually associated with severe carotid artery atherosclerosis (Max-IMT ≥ 1.5 mm). Noncirrhotic men aged ≥ 65 years were most significantly affected by the minor allele of HSPA8. To predict the risk of atherosclerosis and cardiovascular disease, HSPA8 SNP genotyping might be useful, particularly for older male NAFLD patients.

    Purpose: At present, ≥ 20% of patients experience clinically relevant postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP). Methods: We developed a new bioabsorbable pancreatic clip (BioPaC) made of polycaprolactone that does not crush the pancreatic parenchyma during occlusion of the pancreatic stump. We confirmed the efficacy of this BioPac in a porcine DP model and compared it to a linear stapling device (Reinforce®). Results: Pigs were killed at 1 month after DP. In the BioPaC group, all swine (n = 3) survived well without POPF. In the Reinforce® group (n = 2), one pig died early at postoperative day 7 with Grade C POPF (amylase 43 700 U/l), and the other survived until 1 month at scarification with biochemical leakage of POPF (amylase 3 725 U/l). Pathologically, the main pancreatic duct and pancreatic parenchyma were well closed by BioPaC. Conclusion: The newly developed BioPaC is effective in a porcine DP model.

    We herein report the effectiveness of contralateral osteotomy of the pedicle and posterolateral elements for en bloc resection (COPPER) of paraspinal and spinal tumours. This surgical method allows for complete resection of the localized tumour in the lateral posterior lesion without removing the entire vertebral body, as in total en bloc spondylectomy. Complete resection of paraspinal and spinal tumours is challenging for spinal surgeons because of anatomical complexities. Although the COPPER method has been introduced as a less invasive surgical procedure for wide resection of spinal tumours, no studies have reported the usefulness of this technique. We identified three patients with paraspinal or spinal tumours who underwent wide resection using the COPPER method and reviewed their clinical, radiological, and pathological outcomes. In all cases, we resected the spinal and paraspinal tumours extending to the anterior column and extravertebral component using the modified COPPER method. All patients underwent en bloc resection with a negative margin. We report three cases of spinal and paraspinal tumours extending to the anterior column and extravertebral component.

    To investigate useful cytological features for differential diagnosis of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC), this study cytologically compared HCC to ICC using image analysis software. Touch smear specimens of surgically resected specimens were obtained from a total of 61 nodules of HCC and 16 of ICC. The results indicated that the major/minor axis ratio of ICC is significantly larger than that of HCC (1.67 ± 0.27 vs. 1.32 ± 0.11, p < 0.0001) in Papanicolaou staining. This result means that the nucleus of HCC is close to round and the nucleus of ICC is close to an oval. This significant difference in the major/minor axis ratio between ICC and HCC was consistently observed by the same analyses using clinical samples of cytology (4 cases of HCC and 13 cases of ICC) such a fine-needle aspiration, brushing and ascites (ICC: 1.45 ± 0.13 vs. HCC: 1.18 ± 0.056, p = 0.004). We also confirmed that nuclear position center-positioned nucleus (p < 0.0001) and granular cytoplasm (p <0.0001) are typical features of HCC tumor cells compared to ICC tumor cells. The research study found a significant difference in the nuclear morphology of HCC (round shape) and ICC (oval shape) in Papanicolaou-stained cytology specimens. This simple and objective finding will be very useful for the differential cytodiagnosis of HCC and ICC.

    Background & Aims: As alternatives to the expensive liver biopsy for assessing liver fibrosis stage in patients with nonalcoholic fatty liver disease (NAFLD), we directly compared the diagnostic abilities of magnetic resonance elastography (MRE), vibration-controlled transient elastography (VCTE), and two-dimensional shear wave elastography (2D-SWE). Methods: Overall, 231 patients with biopsy-proven NAFLD were included. Intra- and inter-observer reproducibility was analyzed using intraclass correlation coefficient in a sub-group of 70 participants, in whom liver stiffness measurement (LSM) was performed by an elastography expert and an ultrasound expert who was an elastography trainee on the same day. Results: Valid LSMs were obtained for 227, 220, 204, and 201 patients using MRE, VCTE, 2D-SWE, and all three modalities combined, respectively. Although the area under the curve did not differ between the modalities for detecting stage ≥1, ≥2, and ≥3 liver fibrosis, it was higher for MRE than VCTE and 2D-SWE for stage 4. Sex was a significant predictor of discordance between VCTE and liver fibrosis stage. Skin-capsule distance and the ratio of the interquartile range of liver stiffness to the median were significantly associated with discordance between 2D-SWE and liver fibrosis stage. However, no factors were associated with discordance between MRE and liver fibrosis stage. Intra- and inter-observer reproducibility in detecting liver fibrosis was higher for MRE than VCTE and 2D-SWE. Conclusions: MRE, VCTE, and 2D-SWE demonstrated excellent diagnostic accuracy in detecting liver fibrosis in patients with NAFLD. MRE demonstrated the highest diagnostic accuracy for stage 4 detection and intra- and inter-observer reproducibility. UMIN Clinical Trials Registry No. UMIN000031491.

    BACKGROUND: Low-voltage areas (LVAs) in the atria of patients with atrial fibrillation are considered local fibrosis. We hypoth-esized that voltage reduction in the atria is a diffuse process associated with fibrosis and that the presence of LVAs reflects a global voltage reduction. METHODS AND RESULTS: We examined 140 patients with atrial fibrillation and 13 patients with a left accessory pathway (con-trols). High-density bipolar voltage mapping was performed using a grid-mapping catheter during high right atrial pacing. Global left atrial (LA) voltage (VGLA) in the whole LA and regional LA voltage (VRLA) in 6 anatomic regions were evaluated with the mean of the highest voltage at a sampling density of 1 cm2. Patients with atrial fibrillation were categorized into quartiles by VGLA. LVAs were evaluated at voltage cutoffs of 0.1, 0.5, 1.0, and 1.5 mV. Twenty-eight patients with atrial fibrillation also underwent right atrial septum biopsy, and the fibrosis extent was quantified. Voltage at the biopsy site (Vbiopsy) was recorded. VGLA results by category were Q1 (<4.2 mV), Q2 (4.2–5.6 mV), Q3 (5.7–7.0 mV), and Q4 (≥7.1 mV). VRLA at any region was reduced as VGLA decreased. VGLA and VRLA did not differ between Q4 and controls. The presence of LVAs increased as VGLA decreased at any voltage cutoff. Biopsies revealed 11±6% fibrosis, which was inversely correlated with both Vbiopsy and VGLA (r=–0.71 and –0.72, respectively). Vbiopsy was correlated with VGLA (r=0.82). CONCLUSIONS: Voltage reduction in the LA is a diffuse process associated with fibrosis. Presence of LVAs reflects diffuse voltage reduction of the LA.

    The histological diagnosis of type 1 autoimmune pancreatitis (AIP) based on the findings obtained by an endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is feasible, but the diagnostic consistency of this method has not been confirmed. We determined the interobserver agreement among 20 pathologists regarding the diagnosis of type 1 AIP, including the distinction from pancreatic ductal adenocarcinoma (PDAC) using large tissue samples obtained by EUS-FNB. After guidance for diagnosing AIP with biopsy tissues was provided, a round 2 was performed. The median sensitivity and specificity for diagnosing PDAC vs. non-neoplastic diseases were 95.2% and 100%, respectively. In groups of specialists (n = 7) and the generalists (n = 13), Fleiss’ к-values increased from 0.886 to 0.958 and from 0.750 to 0.816 in round 2. The concordance was fair or moderate for obliterative phlebitis and storiform fibrosis but slight for ductal lesion of type 1 AIP. Discordant results were due to ambiguous findings and biopsy tissue limitations. Among the specialists, the ratio of cases with perfect agreement regarding the presence of storiform fibrosis increased in round 2, but agreement regarding obliterative phlebitis or ductal lesions was not improved. Although the histological definite diagnosis of type 1 AIP was achieved by most observers in > 60% of the cases, the confidence levels varied. Because some ambiguities exist, the histological diagnostic levels based on the diagnostic criteria of type 1 AIP should not be taken for granted. Guidance is effective for improving accurate PDAC diagnoses (notably by recognizing acinar-ductal metaplasia) and for evaluating storiform fibrosis.

    Sodium glucose cotransporter-2 inhibitors (SGLT2is) are now widely used to treat diabetes, but their effects on nonalcoholic fatty liver disease (NAFLD) remain to be determined. We aimed to evaluate the effects of SGLT2is on the pathogenesis of NAFLD. A multicenter, randomized, controlled trial was conducted in patients with type 2 diabetes with NAFLD. The changes in glycemic control, obesity, and liver pathology were compared between participants taking ipragliflozin (50 mg/day for 72 weeks; IPR group) and participants being managed without SGLT2is, pioglitazone, glucagon-like peptide-1 analogs, or insulin (CTR group). In the IPR group (n = 25), there were significant decreases in hemoglobin A1c (HbA1c) and body mass index (BMI) during the study (HbA1c, −0.41%, P < 0.01; BMI, −1.06 kg/m2, P < 0.01), whereas these did not change in the CTR group (n = 26). Liver pathology was evaluated in 21/25 participants in the IPR/CTR groups, and hepatic fibrosis was found in 17 (81%) and 18 (72%) participants in the IPR and CTR groups at baseline. This was ameliorated in 70.6% (12 of 17) of participants in the IPR group and 22.2 % (4 of 18) of those in the CTR group (P < 0.01). Nonalcoholic steatohepatitis (NASH) resolved in 66.7% of IPR-treated participants and 27.3% of CTR participants. None of the participants in the IPR group developed NASH, whereas 33.3% of the CTR group developed NASH. Conclusion: Long-term ipragliflozin treatment ameliorates hepatic fibrosis in patients with NAFLD. Thus, ipragliflozin might be effective for the treatment and prevention of NASH in patients with diabetes, as well as improving glycemic control and obesity. Therefore, SGLT2is may represent a therapeutic choice for patients with diabetes with NAFLD, but further larger studies are required to confirm these effects.

    Cerebral infarction (CI) severely affects the prognosis of patients with malignancy. The aim of the study was to compare the pathology of CI between cases with and without malignancy focusing on intracranial Mönckeberg's atherosclerosis. Among 778 autopsy cases of craniotomy, 53 cases of "cerebral infarction without malignancy group" (CI group), 50 cases of "malignant tumor without CI group" (MT group), and 39 cases of "cerebral infarction with malignancy group" (CM group) were identified. Mönckeberg's atherosclerosis was mainly found in the basal ganglia and its prevalence in the CM group (38.5&#37;) was significantly higher than in the MT group (12.0&#37;, p = 0.005), and apparently higher than in the CI group (18.9&#37;, p = 0.057). The CI group was significantly older, had higher BMIs, and a greater prevalence of hypertension and atrial fibrillation compared to the CM group. In addition, the prevalence of chronic renal disease was significantly lower in the CM group (2.6&#37;, p = 0.012) than in the CI group (20.8&#37;). Our results indicated that Mönckeberg's atherosclerosis was often found in the basal ganglia of CM cases and that intracranial Mönckeberg's atherosclerosis is a potential risk factor for CI in patients with advanced stage malignancy.

    Language:English   Publishing type:Research paper (scientific journal)  

    BACKGROUND: Few studies have evaluated both liver fibrosis and steatosis in patients with nonalcoholic fatty liver disease (NAFLD) using both FibroScan® M and XL probes. This study was performed to investigate the accuracy of both FibroScan® probes to diagnose liver fibrosis and steatosis in patients with NAFLD. METHODS: We prospectively enrolled 137 consecutive patients with clinically suspected NAFLD in our joint-research facilities. Liver biopsies, liver stiffness measurements (LSMs), and controlled attenuation parameter (CAP) measurements were performed, and 122 patients with NAFLD diagnosed pathologically by central pathologists were included in the final analysis. RESULTS: Reliable LSM results were obtained in 85.2% (M) and 89.3% (XL) of patients, and CAP was reliable in 90.2% (M) and 90.2% (XL). The median LSM was significantly lower with the XL than M probe, and CAP was significantly higher with the XL than M probe. The optimal cut-off values for diagnosing the fibrosis stage were lower for LSM with the XL than M probe (stage ≥ 2, 6.7 vs. 7.0; stage ≥ 3, 8.2 vs. 10.8; stage 4, 14.3 vs. 16.8, respectively), whereas those of CAP were higher for the XL than M probe (score of ≥ 2, 273 vs. 267; score of 3, 302 vs. 286, respectively). There were no significant differences in accuracy of the LSM and CAP between the probes. CONCLUSIONS: Liver fibrosis and steatosis could be equally evaluated with FibroScan® M and XL probes in patients with NAFLD. There was no significant difference in diagnostic accuracy between the two probes using probe-specific cut-off values.

    BACKGROUND: Tumor immune reactions not only provide host defense but also accelerate tumor immune escape and phenotype switching. Here, we examined the association of programmed cell death ligand 1 (PD-L1) expression with epithelial-mesenchymal transition (EMT)-associated markers in pancreatic ductal adenocarcinoma (PDA) within the context of the tumor microenvironment. MATERIALS AND METHODS: PDA samples from 36 patients were analyzed for PD-L1, vimentin, E-cadherin, and Snail expressions and for PDA cell and immune cell infiltration. PD-L1 expression and EMT in PDA cell lines under conditions of altering interferon gamma (IFN-γ) signals were also assessed. RESULTS: Immunohistochemistry revealed a significant correlation between vimentin and PD-L1 expression, whereas double staining showed them to be simultaneously expressed by PDA cells. Positive vimentin expression was associated with the infiltration of a lower number of CD8+ T cells and a higher number of FoxP3+ cells and poor patient prognosis (P = 0.03). PDA tumor cells promoted PD-L1 expression and EMT under the presence of IFN-γ, which was inhibited by the signal transducer and activator of transcription (STAT)1 small interfering RNA. CONCLUSIONS: Strong correlations were observed between PD-L1 expression, EMT, and the immunosuppressive tumor microenvironment. Targeting STAT1 combined with PD-1/PD-L1 immunotherapy may improve outcomes for patients with PDA.

    Language:English   Publishing type:Research paper (scientific journal)  

    BACKGROUND: Small hepatocellular carcinomas (HCC ≤3 cm) are generally considered to have low malignant potential; however, some of them display pathological microvascular invasion (MVI). METHODS: Between 1991 and 2013, 414 patients with a single HCC ≤3 cm underwent curative hepatic resection (HR). Predictors for MVI were identified. Using another cohort (149 patients during 2000-2014), our predictors for MVI in HCC ≤3 cm were validated. In 428 patients with a single HCC ≤3 cm who had predictors for MVI, survival was compared among anatomical HR (n = 149), partial HR (n = 227), and radiofrequency ablation (RFA) (n = 52). RESULTS: The positive rate of MVI reached 40.6% (168/414 patients). Independent predictors for MVI were as follows: tumor diameter ≥2 cm (odds ratio 1.84, P = .0052), alpha-fetoprotein (AFP) ≥200 ng/mL (odds ratio 1.82, P = .0466), and des-gamma-carboxy prothrombin (DCP) ≥40 mAU/mL (odds ratio 1.79, P = .0126). Matching at least one predictor among these three could predict MVI in HCC ≤3 cm well (sensitivity 82.8%, positive predictive value [PPV] 48.7%). This criterion could also predict MVI in HCC ≤3 cm well in another cohort (sensitivity 82.8%, PPV 30.3%). In patients with single HCC ≤3 cm matching our criterion for predicting MVI, anatomical HR led to significantly better survival in both disease-free (hazard ratio 0.689, P = .0231) and overall (hazard ratio 0.589, P = .0316) survivals. CONCLUSION: Matching at least one factor among three (tumor diameter ≥2 cm, AFP ≥200 ng/mL, or DCP ≥40 mAU/mL) can predict MVI in HCC ≤3 cm. In such patients, anatomical HR would be recommended to improve survival.

     More details

    Language:English   Publishing type:Research paper (scientific journal)  

    The present study aimed to investigate the prognostic usefulness of the expression of glucose transporter type 1 (GLUT-1) and GLUT-2, hypoxia-inducible factor 1α (HIF-1α) and insulin-like growth factor II messenger RNA-binding protein 3 (IMP3) in pancreatic neuroendocrine tumors (pNETs). Immunohistochemical staining for GLUT-1, GLUT-2, HIF-1α and IMP3 was performed in 70 pNET specimens. The expression of GLUT-1 and HIF-1α was significantly higher in the World Health Organization grade 2 (G2), neuroendocrine carcinoma cases and mixed-type pNETs compared with the G1 cases. Vessel invasion, a high Ki-67 labeling index and a high mitotic count were significantly more frequent in the GLUT-1- and HIF-1α-positive cases compared with the negative cases. Lymph node metastasis was significantly higher in the GLUT-1-positive cases than in the negative cases. Insulin expression was significantly higher in the IMP3-positive cases than the negative cases. The GLUT-1 expression group experienced a significantly poor disease-free survival rate compared with the negative GLUT-1 expression group. HIF-1α expression was significantly correlated with poor disease-free survival and overall survival rates. A multivariate analysis revealed that lymph node metastasis was an independent risk factor for disease-free survival in all cases. In the G1/G2 group, tumor size and lymph node metastasis were independent risk factors for disease-free survival. Overall, the results suggested that GLUT-1 is a useful prognostic biomarker for pNETs.

  • Dysregulated YAP1/TAZ and TGF-β signaling mediate hepatocarcinogenesis in Mob1a/1b-deficient mice. International journal

     More details

    Language:English   Publishing type:Research paper (scientific journal)  

    Mps One Binder Kinase Activator (MOB)1A/1B are core components of the Hippo pathway that coactivate large tumor suppressor homolog (LATS) kinases. Mob1a/1b double deficiency in mouse liver (LMob1DKO) results in hyperplasia of oval cells and immature cholangiocytes accompanied by inflammatory cell infiltration and fibrosis. More than half of mutant mice die within 3 wk of birth. All survivors eventually develop liver cancers, particularly combined hepatocellular and cholangiocarcinomas (cHC-CCs) and intrahepatic cholangiocellular carcinomas (ICCs), and die by age 60 wk. Because this phenotype is the most severe among mutant mice lacking a Hippo signaling component, MOB1A/1B constitute the critical hub of Hippo signaling in mammalian liver. LMob1DKO liver cells show hyperproliferation, increased cell saturation density, hepatocyte dedifferentiation, enhanced epithelial-mesenchymal transition and cell migration, and elevated transforming growth factor beta(TGF-β)2/3 production. These changes are strongly dependent on Yes-Associated Protein-1 (Yap1) and partially dependent on PDZ-binding motif (Taz) and Tgfbr2, but independent of connective tissue growth factor (Ctgf). In human liver cancers, YAP1 activation is frequent in cHC-CCs and ICCs and correlates with SMAD family member 2 activation. Drug screening revealed that antiparasitic macrocyclic lactones inhibit YAP1 activation in vitro and in vivo. Targeting YAP1/TAZ with these drugs in combination with inhibition of the TGF-β pathway may be effective treatment for cHC-CCs and ICCs.

    BACKGROUND: Hepatocellular carcinoma (HCC) ≤ 2 cm in diameter is considered to have a low potential for malignancy. METHODS: A retrospective review was undertaken of 149 patients with primary solitary HCC ≤ 2 cm who underwent initial hepatic resection between 1994 and 2010. The independent predictors of the microinvasion (MI) such as portal venous, hepatic vein, or bile duct infiltration and/or intrahepatic metastasis were identified by multivariate analysis. Prognosis of patients with HCC ≤ 2 cm accompanied by MI was compared to that of patients with HCC ≤ 2 cm without MI. RESULTS: Forty-three patients with HCC ≤ 2 cm had MI in patients (28.9%). Three independent predictors of the MI were revealed: invasive gross type (simple nodular type with extranodular growth or confluent multinodular type), des-γ-carboxy prothrombin (DCP) >100 mAU/ml, and poorly differentiated. Disease-free survival rates of patients with HCC ≤ 2 cm with MI (3 year 44%) were significantly worse than those for HCC ≤ 2 cm without MI (3 year 72%). This disadvantage of disease-free survival rate of patients with HCC ≤ 2 cm with MI could be dissolved by hepatic resection with a wide tumor margin of ≥ 5 mm (P = 0.04). CONCLUSIONS: Even in cases of HCC ≤ 2 cm, patients who are suspected of having invasive gross type tumors in preoperative imaging diagnosis or who have a high DCP level (>100 mAU/ml) are at risk for MI. Therefore, in such patients, hepatic resection with a wide tumor margin should be recommended.

    Language:English   Publishing type:Research paper (scientific journal)  

    BACKGROUND: The object of the current study was to review the outcomes of hepatic resection for hepatocellular carcinoma (HCC) ≥ 10 cm. METHODS: Between 1995 and 2007, fifty-three patients with HCC ≥ 10 cm underwent hepatic resection, and clinical data were compared to those of patients with non-surgical treatment (n = 12). Surgical results for HCC ≥ 10 cm were compared to those of patients with HCC < 10 cm (n = 412). The independent poor prognostic factors of the patients with HCC ≥ 10 cm were identified. RESULTS: Overall survival was significantly better in patients with hepatic resection for HCC ≥ 10 cm than in those with non-surgical treatment (P < 0.01). Survival rates of patients with hepatic resection for HCC ≥ 10 cm were 35&#37; at 5 years. Morbidity and mortality rate were statistically equal. The independent poor prognostic factors of patients with hepatic resection for HCC ≥ 10 cm were revealed: T4 status, macroscopic tumor thrombus in portal vein (VP+), and the use of intra-operative transfusion. CONCLUSION: Hepatic resections for HCC ≥ 10 cm are safe and efficacious. Minimizing intra-operative blood loss and the establishment of an effective systemic treatment for patients with HCC ≥ 10 cm in T4 appear to be critical.

    Language:English   Publishing type:Research paper (scientific journal)  

    Ovarian mucinous neoplasms of gastro-intestinal type (GI-type) are known to be a heterogeneous tumor composed of benign, borderline and non-invasive and invasive malignant lesions. The presence of infiltrative invasion is also known to be an important prognostic factor of this neoplasm. Laminin γ 2 chain, known to stimulate tumor cell invasion and migration, has not been sufficiently investigated in ovarian mucinous neoplasms. The purpose of this study was thus to clarify the role of laminin γ 2 in ovarian mucinous neoplasms of GI-type. We selected each morphological phase of tumor development from 61 cases of mucinous neoplasms of the GI-type: 55 adenoma lesions, 60 borderline lesions, 20 microinvasive lesions, 17 intraepithelial carcinoma lesions, 38 expansile invasive carcinoma lesions, 19 infiltrative invasive carcinoma lesions and 5 mural nodules lesions; and evaluated the localization of laminin γ 2 in the lesions using immunohistochemical method. The staining pattern was classified into i) basement membranous (BM), ii) cytoplasmic (CYT) and iii) stromal (S) pattern. The BM pattern was characteristic in adenoma, borderline, and interaepithelial and expansile invasive carcinoma lesions. The CYT and S patterns were characteristic in infiltrative invasive lesions. The staining pattern of mural nodules was similar to that of infiltrative invasion. The infiltrative invasion of GI-type ovarian mucinous neoplasms may be promoted by cytoplasmic and/or stromal expression of laminin γ 2 chain.

    Language:Others   Publishing type:Research paper (scientific journal)  

    We aimed to clarify the clinical significance of des-γ-carboxy prothrombin (DCP) levels in both hepatocellular carcinoma (HCC) and liver tissues with a special reference to the relationship between DCP level in non-cancerous parts of the liver and the multicentric occurrence of HCC. Twenty-eight patients with HCC, who underwent hepatectomy, were studied. Surgical specimens were obtained from both HCC and non-cancerous liver of each patient. After the preparation of the liver tissues, including tissues with HCC, the DCP levels both in HCC and non-cancerous liver tissue were measured using an electro-chemiluminescence immunoassay. The correlation was investigated between DCP levels and other clinicopathological factors. The DCP level of HCC ranged from 55 to 77 735 U/0.1 g tissue weight, with a median of 2801, while the DCP level of non-cancerous parts of the liver ranged from 24 to 721 U/0.1 g tissue weight, with a median of 86. The DCP level in the liver tissue in patients having a multicentric occurrence of HCC was significantly higher than that in patients without multicentric occurrence of HCC. The logarithm of the plasma DCP level correlated with that of the DCP level in HCC (correlation coefficient = 0.46; P < 0.05). No significant correlation was found between the DCP level in HCC and other clinicopathological parameters. The DCP level in non-cancerous parts of the liver with simultaneous multicentric occurrence of HCC was significantly higher than that in the liver without multicentric HCC. Furthermore, the DCP level in non-cancerous parts of the liver was one of the most important predictable factors of the multicentric occurrence of HCCs among various clinicopathological factors. Therefore, the DCP level may have an important role in hepatocarcinogenesis. (C) 2000 Elsevier Science Ireland Ltd.

  • Validation study of age‐independent fibrosis score (Fibrosis‐3 index) in patients with metabolic dysfunction‐associated steatotic liver disease Reviewed

    2024.4

     More details

    Language:Others  

    Abstract

    Background and Aims

    Because the accuracy of the Fibrosis‐4 (FIB‐4) index for predicting liver fibrosis changes with age, the need for different cut‐offs in various age groups has frequently been discussed. We developed the age‐independent score, the Fibrosis‐3 (FIB‐3) index, and have shown its usefulness in patients with metabolic dysfunction‐associated steatotic liver disease (MASLD). This study aimed to validate the diagnostic ability of the FIB‐3 index to predict fibrosis progression using a large new patient cohort.

    Methods

    The ability of the FIB‐3 index to predict liver fibrosis was analyzed by comparing it with that of the FIB‐4 index using data from 1398 patients with MASLD enrolled in the Asia‐based clinical outcome NAFLD study.

    Results

    The areas under the receiver operating characteristic curves for predicting fibrosis stage F3 or higher were not different between the FIB‐3 and FIB‐4 indices in the entire cohort. Using the single ideal cut‐offs of the indices (3.41 for FIB‐3 index and 2.01 for FIB‐4 index), the predictive accuracy of the FIB‐3 index was not significantly different from that of the FIB‐4 index among patients aged <60 years; however, the accuracy of the FIB‐3 index was significantly higher than that of the FIB‐4 index in those aged ≥60 years (0.645 and 0.529, respectively; p < 0.0001).

    Conclusion

    The high ability of the FIB‐3 index with a single cut‐off to predict liver fibrosis in patients with MASLD was confirmed. The FIB‐3 index could serve as a useful tool for assessing liver fibrosis regardless of age.

     More details

    Language:Others  

    Summary

    Aims

    A multi‐stakeholder consensus has proposed MASLD (metabolic dysfunction‐associated steatotic liver disease). We aimed to investigate the pathological findings related to the mid‐term mortality of patients with biopsy‐proven MASLD in Japan.

    Methods

    We enrolled 1349 patients with biopsy‐proven MASLD. The observational period was 8010 person years. We evaluated independent factors associated with mortality in patients with MASLD by Cox regression analysis. We also investigated pathological profiles related to mortality in patients with MASLD using data‐mining analysis.

    Results

    The prevalence of MASH and stage 3/4 fibrosis was observed in 65.6&#37; and 17.4&#37;, respectively. Forty‐five patients with MASLD died. Of these, liver‐related events were the most common cause at 40&#37; (n = 18), followed by extrahepatic malignancies at 26.7&#37; (n = 12). Grade 2/3 lobular inflammation and stage 3/4 fibrosis had a 1.9‐fold and 1.8‐fold risk of mortality, respectively. In the decision‐tree analysis, the profiles with the worst prognosis were characterised by Grade 2/3 hepatic inflammation, along with advanced ballooning (grade 1/2) and fibrosis (stage 3/4). This profile showed a mortality at 8.3&#37;. Furthermore, the random forest analysis identified that hepatic fibrosis and inflammation were the first and second responsible factors for the mid‐term prognosis of patients with MASLD.

    Conclusions

    In patients with biopsy‐proven MASLD, the prevalence of MASH and advanced fibrosis was approximately 65&#37; and 20&#37;, respectively. The leading cause of mortality was liver‐related events. Hepatic inflammation and fibrosis were significant factors influencing mid‐term mortality. These findings highlight the importance of targeting inflammation and fibrosis in the management of patients with MASLD.

    A 71-year-old man who had been pointed out having gallstone was diagnosed with cholelithiasis and adenomyomatosis by preoperative abdominal MRI. Laparoscopic cholecystectomy was performed. The resected specimen included a 25-mm submucosal tumor-like ridging that was found to be a multilocular cystic lesion on the section. Histopathology disclosed adenmyomatosis and multilocular cystic lesion due to mucinous epithelium localized in the gallbladder wall. The cystic epithelium was partly positive for MUC5AC and MCU6, that characterized of gastric-type mucus, with a part comprising low-grade atypical epithelium. Our case was of an intramurally growing cystic lesion localized in the gallbladder wall. Morphologically, it is designated as intramural multicystic mucinous neoplasm with low-grade intraepithelial neoplasia. Due to the rarity of pathological features, we here present this case.

    非アルコール性脂肪肝疾患(nonalcoholic fatty liver disease:NAFLD)とは臨床所見に加え病理学的形態学の概念に基づくもので,大きく非アルコール性脂肪肝(nonalcoholic fatty liver:NAFL)と非アルコール性脂肪性肝炎(nonalcoholic steatohepatitis:NASH)に分類される.NASHは肝硬変や肝細胞癌へと進行する可能性があるので,NAFLとNASHの鑑別診断は重要である.NAFLは肝細胞の傷害を伴わない単純な脂肪肝であるが,NASHは主に小葉中心帯領域(ゾーン3)に分布する大滴性脂肪変性,炎症,風船様肝細胞が特徴である.肝生検はNAFLDを診断する上で有用な検査であるが侵襲的である.ゆえに,診断画像法を含むさまざまな非侵襲性手法が近年開発されている.NAFLDにおける画像診断の有用性を検証するためには,画像診断と組織病理学的所見は密接に関連しているので,病理組織所見が画像所見にどのように反映されているのかを明らかにする必要がある.ここでは,NAFLDの主な病理学的所見,すなわち肝細胞の脂肪変性,炎症,風船様肝細胞,Mallory-Denk体,線維化について概説し,肝硬変への進行過程についても説明を加えた.(著者抄録)

    A 54-year-old woman was diagnosed with acute adult T-cell leukemia (ATL) in November 2015 and underwent allogeneic hematopoietic stem cell transplantation in March 2016. Cognitive impairment appeared suddenly around May 2019, and MRI of the brain showed cerebral white matter lesions. Cerebrospinal fluid examination showed no significant findings other than elevated protein. Brain biopsy showed inflammatory cells, (mainly CD8-positive T lymphocytes), infiltrating the white matter. Based on the pathological findings and the history of chronic graft versus host disease (GVHD) in the lungs and intestines, we diagnosed central nervous system involvement of GVHD (CNS-GVHD). Immunotherapy with steroids and mycophenolate mofetil resulted in improvement of the cognitive dysfunction and inflammatory findings in the spinal fluid. This case is the first report of CNS-GVHD in ATL, suggesting the importance of diagnosis by brain biopsy and the efficacy of immunotherapy.

    Nonalcoholic fatty liver disease (NAFLD) is based on the concept of pathological morphology as well as clinical findings, and is broadly categorized into nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH). The differential diagnosis between NAFL and NASH is important because NASH has the potential to progress to cirrhosis and hepatocellular carcinoma. NAFL is simple hepatic steatosis without hepatocellular injury, while NASH is characterized by macrovesicular steatosis, inflammation, and ballooning hepatocytes with a predominantly centrilobular (zone 3) distribution. Liver biopsy is a useful test for diagnosing NAFLD, but it is invasive. Therefore, various noninvasive methods including diagnostic imaging have been developed in recent years. To verify their usefulness, it is necessary to clarify in detail how the pathological findings are reflected in the image findings as imaging and histopathological findings are closely related. We describe the main histological features of NAFLD, i.e., steatosis, inflammation, ballooning hepatocytes, Mallory-Denk bodies, and fibrosis, as well as the evolutional process to liver cirrhosis.

    Language:English  

    BACKGROUND: Few studies have evaluated both liver fibrosis and steatosis in patients with nonalcoholic fatty liver disease (NAFLD) using both FibroScan® M and XL probes. This study was performed to investigate the accuracy of both FibroScan® probes to diagnose liver fibrosis and steatosis in patients with NAFLD. METHODS: We prospectively enrolled 137 consecutive patients with clinically suspected NAFLD in our joint-research facilities. Liver biopsies, liver stiffness measurements (LSMs), and controlled attenuation parameter (CAP) measurements were performed, and 122 patients with NAFLD diagnosed pathologically by central pathologists were included in the final analysis. RESULTS: Reliable LSM results were obtained in 85.2&#37; (M) and 89.3&#37; (XL) of patients, and CAP was reliable in 90.2&#37; (M) and 90.2&#37; (XL). The median LSM was significantly lower with the XL than M probe, and CAP was significantly higher with the XL than M probe. The optimal cut-off values for diagnosing the fibrosis stage were lower for LSM with the XL than M probe (stage ≥ 2, 6.7 vs. 7.0; stage ≥ 3, 8.2 vs. 10.8; stage 4, 14.3 vs. 16.8, respectively), whereas those of CAP were higher for the XL than M probe (score of ≥ 2, 273 vs. 267; score of 3, 302 vs. 286, respectively). There were no significant differences in accuracy of the LSM and CAP between the probes. CONCLUSIONS: Liver fibrosis and steatosis could be equally evaluated with FibroScan® M and XL probes in patients with NAFLD. There was no significant difference in diagnostic accuracy between the two probes using probe-specific cut-off values.

     More details

    Language:English  

    BACKGROUND: Tumor immune reactions not only provide host defense but also accelerate tumor immune escape and phenotype switching. Here, we examined the association of programmed cell death ligand 1 (PD-L1) expression with epithelial-mesenchymal transition (EMT)-associated markers in pancreatic ductal adenocarcinoma (PDA) within the context of the tumor microenvironment. MATERIALS AND METHODS: PDA samples from 36 patients were analyzed for PD-L1, vimentin, E-cadherin, and Snail expressions and for PDA cell and immune cell infiltration. PD-L1 expression and EMT in PDA cell lines under conditions of altering interferon gamma (IFN-γ) signals were also assessed. RESULTS: Immunohistochemistry revealed a significant correlation between vimentin and PD-L1 expression, whereas double staining showed them to be simultaneously expressed by PDA cells. Positive vimentin expression was associated with the infiltration of a lower number of CD8+ T cells and a higher number of FoxP3+ cells and poor patient prognosis (P = 0.03). PDA tumor cells promoted PD-L1 expression and EMT under the presence of IFN-γ, which was inhibited by the signal transducer and activator of transcription (STAT)1 small interfering RNA. CONCLUSIONS: Strong correlations were observed between PD-L1 expression, EMT, and the immunosuppressive tumor microenvironment. Targeting STAT1 combined with PD-1/PD-L1 immunotherapy may improve outcomes for patients with PDA.

  • Microvascular invasion of single small hepatocellular carcinoma ≤3 cm: Predictors and optimal treatments.

    2018.5

     More details

    Language:English  

    BACKGROUND: Small hepatocellular carcinomas (HCC ≤3 cm) are generally considered to have low malignant potential; however, some of them display pathological microvascular invasion (MVI). METHODS: Between 1991 and 2013, 414 patients with a single HCC ≤3 cm underwent curative hepatic resection (HR). Predictors for MVI were identified. Using another cohort (149 patients during 2000-2014), our predictors for MVI in HCC ≤3 cm were validated. In 428 patients with a single HCC ≤3 cm who had predictors for MVI, survival was compared among anatomical HR (n = 149), partial HR (n = 227), and radiofrequency ablation (RFA) (n = 52). RESULTS: The positive rate of MVI reached 40.6&#37; (168/414 patients). Independent predictors for MVI were as follows: tumor diameter ≥2 cm (odds ratio 1.84, P = .0052), alpha-fetoprotein (AFP) ≥200 ng/mL (odds ratio 1.82, P = .0466), and des-gamma-carboxy prothrombin (DCP) ≥40 mAU/mL (odds ratio 1.79, P = .0126). Matching at least one predictor among these three could predict MVI in HCC ≤3 cm well (sensitivity 82.8&#37;, positive predictive value [PPV] 48.7&#37;). This criterion could also predict MVI in HCC ≤3 cm well in another cohort (sensitivity 82.8&#37;, PPV 30.3&#37;). In patients with single HCC ≤3 cm matching our criterion for predicting MVI, anatomical HR led to significantly better survival in both disease-free (hazard ratio 0.689, P = .0231) and overall (hazard ratio 0.589, P = .0316) survivals. CONCLUSION: Matching at least one factor among three (tumor diameter ≥2 cm, AFP ≥200 ng/mL, or DCP ≥40 mAU/mL) can predict MVI in HCC ≤3 cm. In such patients, anatomical HR would be recommended to improve survival.

     More details

    Language:English  

    The present study aimed to investigate the prognostic usefulness of the expression of glucose transporter type 1 (GLUT-1) and GLUT-2, hypoxia-inducible factor 1α (HIF-1α) and insulin-like growth factor II messenger RNA-binding protein 3 (IMP3) in pancreatic neuroendocrine tumors (pNETs). Immunohistochemical staining for GLUT-1, GLUT-2, HIF-1α and IMP3 was performed in 70 pNET specimens. The expression of GLUT-1 and HIF-1α was significantly higher in the World Health Organization grade 2 (G2), neuroendocrine carcinoma cases and mixed-type pNETs compared with the G1 cases. Vessel invasion, a high Ki-67 labeling index and a high mitotic count were significantly more frequent in the GLUT-1- and HIF-1α-positive cases compared with the negative cases. Lymph node metastasis was significantly higher in the GLUT-1-positive cases than in the negative cases. Insulin expression was significantly higher in the IMP3-positive cases than the negative cases. The GLUT-1 expression group experienced a significantly poor disease-free survival rate compared with the negative GLUT-1 expression group. HIF-1α expression was significantly correlated with poor disease-free survival and overall survival rates. A multivariate analysis revealed that lymph node metastasis was an independent risk factor for disease-free survival in all cases. In the G1/G2 group, tumor size and lymph node metastasis were independent risk factors for disease-free survival. Overall, the results suggested that GLUT-1 is a useful prognostic biomarker for pNETs.

  • Dysregulated YAP1/TAZ and TGF-β signaling mediate hepatocarcinogenesis in Mob1a/1b-deficient mice.

    2016.1

     More details

    Language:English  

    Mps One Binder Kinase Activator (MOB)1A/1B are core components of the Hippo pathway that coactivate large tumor suppressor homolog (LATS) kinases. Mob1a/1b double deficiency in mouse liver (LMob1DKO) results in hyperplasia of oval cells and immature cholangiocytes accompanied by inflammatory cell infiltration and fibrosis. More than half of mutant mice die within 3 wk of birth. All survivors eventually develop liver cancers, particularly combined hepatocellular and cholangiocarcinomas (cHC-CCs) and intrahepatic cholangiocellular carcinomas (ICCs), and die by age 60 wk. Because this phenotype is the most severe among mutant mice lacking a Hippo signaling component, MOB1A/1B constitute the critical hub of Hippo signaling in mammalian liver. LMob1DKO liver cells show hyperproliferation, increased cell saturation density, hepatocyte dedifferentiation, enhanced epithelial-mesenchymal transition and cell migration, and elevated transforming growth factor beta(TGF-β)2/3 production. These changes are strongly dependent on Yes-Associated Protein-1 (Yap1) and partially dependent on PDZ-binding motif (Taz) and Tgfbr2, but independent of connective tissue growth factor (Ctgf). In human liver cancers, YAP1 activation is frequent in cHC-CCs and ICCs and correlates with SMAD family member 2 activation. Drug screening revealed that antiparasitic macrocyclic lactones inhibit YAP1 activation in vitro and in vivo. Targeting YAP1/TAZ with these drugs in combination with inhibition of the TGF-β pathway may be effective treatment for cHC-CCs and ICCs.

    Language:English  

    BACKGROUND: Hepatocellular carcinoma (HCC) ≤ 2 cm in diameter is considered to have a low potential for malignancy. METHODS: A retrospective review was undertaken of 149 patients with primary solitary HCC ≤ 2 cm who underwent initial hepatic resection between 1994 and 2010. The independent predictors of the microinvasion (MI) such as portal venous, hepatic vein, or bile duct infiltration and/or intrahepatic metastasis were identified by multivariate analysis. Prognosis of patients with HCC ≤ 2 cm accompanied by MI was compared to that of patients with HCC ≤ 2 cm without MI. RESULTS: Forty-three patients with HCC ≤ 2 cm had MI in patients (28.9&#37;). Three independent predictors of the MI were revealed: invasive gross type (simple nodular type with extranodular growth or confluent multinodular type), des-γ-carboxy prothrombin (DCP) >100 mAU/ml, and poorly differentiated. Disease-free survival rates of patients with HCC ≤ 2 cm with MI (3 year 44&#37;) were significantly worse than those for HCC ≤ 2 cm without MI (3 year 72&#37;). This disadvantage of disease-free survival rate of patients with HCC ≤ 2 cm with MI could be dissolved by hepatic resection with a wide tumor margin of ≥ 5 mm (P = 0.04). CONCLUSIONS: Even in cases of HCC ≤ 2 cm, patients who are suspected of having invasive gross type tumors in preoperative imaging diagnosis or who have a high DCP level (>100 mAU/ml) are at risk for MI. Therefore, in such patients, hepatic resection with a wide tumor margin should be recommended.

    2010.12

     More details

    Language:English  

    Ovarian mucinous neoplasms of gastro-intestinal type (GI-type) are known to be a heterogeneous tumor composed of benign, borderline and non-invasive and invasive malignant lesions. The presence of infiltrative invasion is also known to be an important prognostic factor of this neoplasm. Laminin γ 2 chain, known to stimulate tumor cell invasion and migration, has not been sufficiently investigated in ovarian mucinous neoplasms. The purpose of this study was thus to clarify the role of laminin γ 2 in ovarian mucinous neoplasms of GI-type. We selected each morphological phase of tumor development from 61 cases of mucinous neoplasms of the GI-type: 55 adenoma lesions, 60 borderline lesions, 20 microinvasive lesions, 17 intraepithelial carcinoma lesions, 38 expansile invasive carcinoma lesions, 19 infiltrative invasive carcinoma lesions and 5 mural nodules lesions; and evaluated the localization of laminin γ 2 in the lesions using immunohistochemical method. The staining pattern was classified into i) basement membranous (BM), ii) cytoplasmic (CYT) and iii) stromal (S) pattern. The BM pattern was characteristic in adenoma, borderline, and interaepithelial and expansile invasive carcinoma lesions. The CYT and S patterns were characteristic in infiltrative invasive lesions. The staining pattern of mural nodules was similar to that of infiltrative invasion. The infiltrative invasion of GI-type ovarian mucinous neoplasms may be promoted by cytoplasmic and/or stromal expression of laminin γ 2 chain.

  • The role of des-γ-carboxy prothrombin levels in hepatocellular carcinoma and liver tissues

    We aimed to clarify the clinical significance of des-γ-carboxy prothrombin (DCP) levels in both hepatocellular carcinoma (HCC) and liver tissues with a special reference to the relationship between DCP level in non-cancerous parts of the liver and the multicentric occurrence of HCC. Twenty-eight patients with HCC, who underwent hepatectomy, were studied. Surgical specimens were obtained from both HCC and non-cancerous liver of each patient. After the preparation of the liver tissues, including tissues with HCC, the DCP levels both in HCC and non-cancerous liver tissue were measured using an electro-chemiluminescence immunoassay. The correlation was investigated between DCP levels and other clinicopathological factors. The DCP level of HCC ranged from 55 to 77 735 U/0.1 g tissue weight, with a median of 2801, while the DCP level of non-cancerous parts of the liver ranged from 24 to 721 U/0.1 g tissue weight, with a median of 86. The DCP level in the liver tissue in patients having a multicentric occurrence of HCC was significantly higher than that in patients without multicentric occurrence of HCC. The logarithm of the plasma DCP level correlated with that of the DCP level in HCC (correlation coefficient = 0.46; P < 0.05). No significant correlation was found between the DCP level in HCC and other clinicopathological parameters. The DCP level in non-cancerous parts of the liver with simultaneous multicentric occurrence of HCC was significantly higher than that in the liver without multicentric HCC. Furthermore, the DCP level in non-cancerous parts of the liver was one of the most important predictable factors of the multicentric occurrence of HCCs among various clinicopathological factors. Therefore, the DCP level may have an important role in hepatocarcinogenesis. (C) 2000 Elsevier Science Ireland Ltd.
