title: Antihepatitis C virus status in hepatocellular carcinoma and the influence on clinicopathological findings and operative results.
abstract: Antihepatitis C virus (HCV) status was investigated in 100 patients undergoing hepatectomy for hepatocellular carcinoma (HCC) between 1980 and 1989. The clinicopathological findings and operative results, in patients with or without HCV marker, were compared retrospectively. The positivity rate of anti-HCV was 51 per cent. In this group there was a higher mean age, fewer symptoms, raised alanine aminotransferase level, higher 15-min indocyanine green clearance rate and earlier tumour stage compared with the anti-HCV negative group. Positive tumour margins and vascular invasion were seen less frequently in the anti-HCV positive group. HCC with HCV marker showed characteristic features of chronic non-A non-B hepatitis and of HCC originating from liver cirrhosis. There was a better cumulative 1-year survival rate for anti-HCV positive patients, but 3- and 5-year survival rates after hepatectomy were similar in both groups. Although HCV-related HCC had typical features of chronic non-A non-B hepatitis and a relatively early stage of tumour, biological features and operative results were similar with or without the HCV marker.
