Hepatitis C virus infection in the development of hepatocellular carcinoma in cirrhosis (original) (raw)

1997, Journal of Hepatology

Backgvoun&Xms: The role of hepatitis C virus replication and different genotypes in the progression of cirrhosis to hepatocellular carcinoma is examined on the basis of a prospective follow-up of 1438 patients with histologically proven cirrhosis. Methods: The presence of HCV RNA, anti-HCV and characterisation of virus genotypes were determined in 72 cases who developed hepatocellular carcinoma after a median follow-up of 5.3 years (range 1 to 16) and compared to 72 controls who had cirrhosis only, after a median follow-up of 4.8 years (range 1 to 16). Patients in the hepatocellular carcinoma group and controls were matched, one to one, for age, sex, nationality, HBsAg seropositivity, duration of followup and aetiology of cirrhosis. Results: HCV RNA was detected in 31 of 72 (44%) patients who developed hepatocellular carcinoma, significantly more frequently than in 17 of 72 (23%) controls with cirrhosis (odds ratio 2.4, 95% confidence LTHOUGH the pathogenesis of hepatocellular carci-
