Abstract

A case control study consisting of 102 patients with HCC, 102 sex‐matched and age‐matched patients with nonhepatic disease, and 204 matched healthy controls was carried out to investigate the effect of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection on the development of hepatocellular carcinoma (HCC). The prevalence of antibody to HCV (anti‐HCV) in HCC (34.3%) was higher than in nonhepatic disease (10.7%, P< 0.001) or in healthy controls (2.4%, P< 0.001). The prevalence of hepatitis B surface antigen (HBsAg) in HCC (77.4%) was higher than in nonhepatic disease (16.6%, P< 0.001) or in healthy controls (19.6%, P< 0.001). Anti‐HCV positivity in nonhepatic disease was higher than in healthy controls (P<0.01). Using patients with nonhepatic disease as controls, stepwise logistic regression analysis indicated that both anti‐HCV (odds ratio, 3.4; 95% confidence interval, 2.1‐5.6) and HBsAg (odds ratio, 5.6; 95% confidence interval, 3.6–8.5) are independent risk factors for HCC. Using healthy controls, the development of HCC was also strongly associated with anti‐HCV (odds ratio, 8.0; 95% confidence interval, 4.3–14.6) and HBsAg (odds ratio, 5.5; 95% confidence interval, 3.7–8.2). Calculation of incremental odds ratio indicated that there is no interaction between HBV and HCV. In conclusion, HBV and HCV are risk factors of HCC. They act independently and without interaction. © 1994 Wiley‐Liss, Inc.
