title: Prognosis after hepatic resection in patients with hepatocellular carcinoma, estimated on the basis of the morphometric indices.
abstract: To determine whether the morphometric indices of hepatocellular carcinoma (HCC) correlated with the prognoses, the microscopic morphometric values for 84 HCC cases treated by hepatic resection were studied using an image analyzer in relation to the survival rate and the gross classification. The mean survival time (MST) was 58 months in cases with a nucleocytoplasmic area ratio (N/C) of less than 0.28; this was significantly longer than the 38-month MST in cases with an N/C of more than 0.28 (P < 0.05). In stage III disease, the MST for cases with an N/C of less than 0.28 was 63 months, which was significantly longer than the MST of 13 months for cases with an N/C of more than 0.28. After relatively noncurative hepatic resection, the MST for cases with an N/C of less than 0.28 was 49 months, and this was significantly longer than the MST of 8 months for cases with an N/C of more than 0.28. The MST was 71 months for cases with a coefficient of variance of the nuclear form factor (NCV) of less than 5.5%, which was significantly longer than the MST of 33 months for cases with an NCV of more than 5.5% (P < 0.05). In stage III disease, the MST was 69 months for cases with an NCV of less than 5.5%, and this was significantly longer than the MST of 29 months for cases with an NCV of more than 5.5% (P < 0.05). In cases with an N/C of less than 0.28, 18% had vascular invasion and 38% had intrahepatic metastases, whereas in those with an N/C of more than 0.28, 62% had vascular invasion and 67% had intrahepatic metastases (P < 0.01, P < 0.05). Based on the results of these morphometric studies on HCC cases treated by hepatic resection, N/C and NCV may be useful as prognostic factors.
