Surgical results in patients with hepatitis virus-related hepatocellular carcinoma in Taiwan.

Abstract

To investigate the surgical results of hepatectomy for hepatocellular carcinoma in relation to hepatitis virus status in Taiwan, 252 patients (196 men and 56 women; March 1992 to August 1998) were reviewed. The patients were divided into four groups: 30 patients (11.9%) seronegative for both hepatitis B surface antigen (HBsAg) and antihepatitis C antibody (HCVAb) (N-HCC group); 133 patients (52.8%) seropositive for HBsAg and seronegative for HCVAb (B-HCC group); 66 patients (26.2%) seronegative for HBsAg and seropositive for HCVAb (C-HCC group); and 23 patients (9.1%) seropositive for both HBsAg and HCVAb (BC-HCC group). Patients in group C-HCC were older (p = 0.001) and had a higher incidence of diabetes mellitus (p = 0.004). Also, they had a higher indocyanine green retention rate at 15 minutes (p = 0.021), longer international normalization ratio for the prothrombin time (p = 0.049), and smaller tumor (p = 0.006). Postoperative complications and hospital mortality were significantly higher in patients in the C-HCC and BC-HCC groups (p = 0.046, 0.021). All patients were followed 12 to 76 months after hepatectomy (mean 23.5 +/- 16.3 months). The 1-, 3-, and 5-year overall cumulative survival rates of the 252 patients in this series were 80%, 54.3%, and 34.2%, respectively. The cumulative intrahepatic recurrence rates were 46.5%, 64.9%, and 72.9% at 1, 3, and 5 years, respectively. The mean disease-free survival time was longest in group C-HCC and shortest in group BC-HCC (p = 0.020). The overall survival time and cumulative survival rates in the four groups were not significantly different (p = 0.146).
