Abstract
Previous infection with hepatitis B virus (HBV), which is assessed by HBV core antibody (HBcAb) or surface antibody (HBsAb) titres, has reportedly been associated with an increased risk of developing hepatocellular carcinoma (HCC). We investigated the influence of previous HBV infection on the incidence of HCC in patients with hepatitis C virus (HCV) infection who achieved eradication of HCV, that is sustained virologic response (SVR). Both HBcAb and HBsAb were measured in a total of 1214 patients with HCV infection who had not been coinfected with HBV, as determined by both negative HBs antigen and HBV DNA, and in whom SVR was confirmed. Patients were followed up for a median of 5.7 years, and the incidence of post-SVR HCC was compared based on HBcAb and/or HBsAb. In both univariate and multivariate analyses, the incidence of post-SVR HCC did not differ based on the presence of HBcAb or HBsAb. In conclusion, previous HBV infection has no impact on the incidence of HCC in patients with HCV after SVR.
