- The programmed cell death-1 (PD-1) and programmed cell death-ligand-1 (PD-L1) signaling pathways are potent T-cell inhibitory pathways that cancer cells use to evade tumor control by host autoimmunity. Immune checkpoint inhibitors, which use antibodies to block this pathway, have been shown to have potent anti-tumor effects in some cancers.In Japan, nivolumab has been approved for the treatment of cancer. In Japan, nivolumab (Opdivo) was approved for the treatment of malignant melanoma that is not curatively resectable, followed by renal cell carcinoma, recurrent non-small cell carcinoma, and Hodgkin lymphoma.In Japan, nivolumab (Opdivo) was approved for the treatment of incurable malignant melanoma, followed by renal cell carcinoma, recurrent non-small cell carcinoma, Hodgkin lymphoma, and gastric cancer, and is likely to be rapidly expanded to other cancer types in the future. However, the drug is extremely expensive.However, this drug is not only extremely expensive, but also has a certain frequency of poor therapeutic effects and is known to cause serious side effects.Therefore, it is essential to establish an appropriate method for selecting patients who are expected to benefit from treatment. PD-L1 expression in tumors is a biomarker that predicts response to anti-PD-1/anti-PD-L1 therapy.Although direct immunostaining with biopsy has been the only method to evaluate PD-L1 expression, biopsy of all lesions is not feasible, especially for multiple lesions.
However, biopsy of all lesions is impractical, especially in patients with multiple metastases. However, biopsy of all lesions is not feasible, especially in patients with multiple metastases. In addition, PD-L1 expression may be heterogeneous in multiple lesions within the same individual and may change dynamically with treatment.Therefore, it is desirable to establish a non-invasive evaluation method. Recently, a method to image PDL1 expression using positron emission tomography has been reported.The purpose of this study is to prepare 18F-PD-L1, which is labeled with 18F, and to apply it clinically through animal experiments. Since it is a new tracer, there are few reports of clinical studies.Since it is a new tracer, there have been few reports of clinical studies, and its clinical usefulness has not yet been confirmed, so the results of clinical studies are awaited at an early stage. In this fiscal year, we constructed a facility for the synthesis of radionuclides suitable for antibody labeling and prepared for the synthesis. - To demonstrate the usefulness of FDG-PET/CT for the diagnosis of fever of unknown origin (FUO), we will compare the sensitivity of FDG-PET/CT and that of gallium SPECT for the detection of fever origin.

A reverse relationship between iodine and FDG accumulation is found in thyroid cancer lesions, the so-called “flip-flop” phenomenon. The aim of this study was to assess the relationship between iodine and FDG uptake in bone metastasis lesions from thyroid cancer.Methods: The cases of 20 patients who underwent radioiodine therapy for bone metastasis were studied retrospectively (age, 27-74 yrs; median, 62 yrs; males : females, 6 : 14). Iodine uptake was evaluated visually and the lesions showing iodine uptake more than background were determined as positive. FDG uptake was assessed using SUVmax. We compared FDG uptake between the lesions with (n=19) and without (n=88) iodine uptake in bone metastasis.Results: The bone metastasis lesions without iodine showed significantly higher FDG uptake than those with iodine uptake (p 5). Enormously high degree of FDG uptake (SUVmax>10) was rare in the lesions with iodine uptake, while it was common in those without iodine uptake.. |

We undertook this study to directly compare visual and semiquantitative analysis for the evaluation of recurrence in brain tumors. Method Thirty-nine patients with a history of treated brain tumors (32 primary brain tumor and 7 metastatic tumor) referred for evaluation of recurrent disease were initially included in the study. There were 24 males and 15 females (mean age: 39.1. ± 15.4 years; range: 15 to 69 years). All patients are suspected recurrence, persistence, or necrotic post-therapeutic changes and underwent the MET PET/CT study. Visual image interpretation was performed independently by 2 PET physicians using the fused PET/CT images. Images were also analyzed semiquantitatively using ratio of SUVmax of tumor and normal contralateral white matter (T/Nw) and grey matter (T/Ng). Imaging results were compared with histopathology on tumor excision or biopsy in 12 patients and with clinical follow-up in 27 patients. Results The final diagnosis was tumor recurrence in 28 patients and no recurrence/stable disease in 11 patients. Visual analyses were positive in 25 (64.1%) and negative in 9 (35.9%). The sensitivity, specificity and accuracy were 82.1%, 81.8% and 82.1% respectively. For the semiquantitative analysis, positive cases were seen in 26 (66.7%) (TNw) and 25 (64.1%) (TNg). The sensitivity, specificity and accuracy were [89.3(TNw); 85.7(TNg)], [90.9(TNw); 90.9(TNg)] and [89.7(TNw); 87.2(TNg)] respectively. Highest AUC of 0.93 was seen in TNw using the cut-off value of 1.95. There was no statistically significant differences among three methods. Conclusion Although, it was a slight difference, diagnostic performance using semiquantitative analysis using T/Nw was the best among the three method used in this study. MET-PET/CT was a useful technique to differentiate post-therapeutic changes from tumor presence in treated patients with brain tumor in whom diagnosis was nonconclusive. . |
| 10. | Shingo Baba, Takuro Isoda, Yoshiyuki Kitamura, Clinical Impact of radiolabeled amino acid PET for the diagnosis of cerebral gliomas, THE 13TH ASIA OCEANIA CONGRESS OF NUCLEAR MEDICINE AND BIOLOGY, 2019.05, BACKGROUND: Magnetic resonance imaging (MRI) is the investigation of choice for diagnosing cerebral glioma, but its capacity to differentiate tumor tissue from non-specific tissue changes is limited. 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) is a molecular imaging technique, which provides information on the metabolic behavior of the tumor. However, FDG-PET often leads to several controversies in making clinical decisions due to their high uptake of normal surrounding tissues, and pose difficulty in delineating treatment-induced necrosis, edema, inflammation, and pseudoprogression. Thus, it is imperative to find new approach to demarcate normal and tumor tissues. PET using radiolabeled amino acids is a promising technique and it increases diagnostic accuracy for brain tumor. PURPOSE: We have provided some cases and literature of 11C methionine-PET (MET-PET) and other amino acid PET for gliomas, along with prognostic and diagnostic significance. METHODS: Review based on the authors' own research results and a selective literature review RESULTS: The use of radiolabeled amino acids allows better delineation of tumor margins and improves targeting of biopsy and radiotherapy, and planning surgery. In addition, amino acid imaging appears useful in distinguishing tumor recurrence from non-specific post-therapeutic necrosis, in predicting prognosis in low grade gliomas, and in monitoring metabolic response during treatment. CONCLUSION: Amino acid PET including MET-PET can lead to a better understanding of the existing controversies and can enhance our knowledge for future treatment of GBM patients based on their tumor gene signatures to achieve better prognosis and treatment outcome.. |

We undertook this study to directly compare F-18 flurodeoxyglucose (FDG) PET and C-11 methionine (MET) PET for the evaluation of recurrence in brain tumors. Method Thirty-seven patients with a history of treated brain tumors (31 primary brain tumor and 6 metastatic tumor) referred for evaluation of recurrent disease were initially included in the study. There were 22 males and 15 females (mean age: 38.7 ± 14.4 years; range: 15 to 65 years). All patients underwent the MET and FDG study within 2 weeks. Visual image interpretation was performed independently by 2 PET physicians for each tracer using the fused PET/CT images. Images were analyzed semiquantitatively using tumor to normal contralateral cortex ratios (T/N). Imaging results were compared with histopathology on tumor excision or biopsy in 10 patients and with clinical follow-up in 27 patients. Results The final diagnosis was tumor recurrence in 27 patients and no recurrence/stable disease in 10 patients. On FDG, findings in 23/37 (62.2%) were suggestive of recurrent tumors. On MET, findings in 28/37 (75.7%) cases were suggestive of recurrent tumors. Spatially separated secondary lesions were clearly delineated in 4 cases, 3 were glioblastoma multiforme (GBM) and 1 were anaplastic astrocytoma. Two of the secondary lesions were missed on FDG PET. Using a cutoff for T/N ratio on FDG of >0.90 to differentiate recurrence from no recurrence, sensitivity of FDG was 74.1%, whereas specificity was 70.0%. Area under the curve was 0.86. Using a cutoff for T/N ratio of >2.1 to differentiate recurrence from no recurrence, sensitivity of MET was 92.6%, whereas specificity was 80.0%. Area under the curve was 0.95. Conclusion Semiquantitative analysis of MET can provide more informative values than FDG to aid in the differentiation of tumor recurrence from radiation necrosis. . |

Materials and Methods: Previously reported recovery-collection using simple table look-up method was used in this study. Recovery coefficient was estimated using size and signal-background ratio by phantom experiment. Fifty three patients of malignant lymphoma (DLBCL; 37, FL; 16) were subjected to FDG-PET/CT for initial staging. Recovery-collected SUVs (SUVcor) were calculated and average±SD, coefficient of variation (CV) of SUVcor were compared with those of conventional SUV within the patient and between the groups divided by histology and prognosis. Result: Average±SD of SUVmax, SUVcor were higher in DLBCL (14.5±9.1, 18.6±9.6) than in FL(8.5±2.6, 11.7±3.24)( pConclusion: Uptakes of FDG free from partial-volume effect can be measured correctly with this method. Variability of pretreatment SUVs with size-collection is one of the independent predictor of the prognosis of patient with DLBCL. . |
