Daisuke Tsurumaru, Yusuke Nishimuta, Toshio Muraki, Yoshiki Asayama, Hiroshi Honda, Prediction of gastric cancer with synchronous hepatic metastasis by enhancement pattern of primary lesion using multiphasic contrast-enhanced computed tomography, European Congress of Radiology 2018, 2018.03, Purpose: To examine contrast-enhanced computed tomography (CECT) features of primary site of gastric cancers with synchronous hepatic metastasis.
Methods and Materials: One hundred eleven consecutive patients with pathologically proven advanced gastric cancers who were evaluated with CECT were enrolled. CT images were obtained 40s (arterial phase), 70s (portal phase) and 240s (delayed phase) after injection of nonionic contrast material. Eleven patients were diagnosed having hepatic metastasis at the time of diagnosis. Two radiologists in consensus determined the “peak enhancement phase” in which the lesion showed the highest attenuation value among the three phases for each case. The readers traced the entire tumor as the region of interest (ROI) of the gastric lesion, and measured the CT attenuation value for each phase. We compared the peak enhancement phase of positive hepatic metastasis group (n=11) and negative hepatic metastasis group (n=100) using Chi-square tests, and compared the CT attenuation values of the two groups in each phase using analysis of variance (ANOVA).
Results: The peak enhancement was significantly different between the two groups (p=0.0007); most of the positive hepatic metastasis cases had peak enhancement in the arterial phase. The CT attenuation values of positive hepatic metastasis cases were significantly lower than those of negative hepatic metastasis cases in the delayed phase.
Conclusion: Hepatic metastasis of gastric cancer may be predictable according to enhancement pattern of primary lesion on multiphasic CECT..
