- Abstract
- Background and AimsThe outcomes of hepatitis C virus (HCV)-related liver cirrhosis was limitedly studied in a hepatitis B virus-endemic area. This multicenter, prospective cohort study was conducted to elucidate the incidence of hepatocellular carcinoma (HCC) and mortality in the Korean patients with HCV-related cirrhosis. MethodsFrom January 2007 through June 2012, 196 patients with HCV-related cirrhosis were prospectively enrolled and regularly followed at six university hospitals to determine HCC occurrence and mortality. A multivariable analysis using Cox proportional hazards regression was performed to clarify the related factors to the outcomes. ResultsDuring a mean follow-up period of 39.2 months, 31 (15.8%) patients developed HCC, and 33 (16.8%) patients died or underwent liver transplantation. The estimated HCC incidence was 5.8 per 100 person-years, and the independent factors for HCC were absence of anti-HBV surface antibody (HBs hazard ratio [HR], 5.018; 95% confidence interval [CI], 1.710-14.726; P=0.003) and serum albumin<3.8g/dL (HR, 3.051; 95% CI, 1.318-7.067; P=0.009). The overall mortality rate was 5.1 per 100 person-years, and the related independent factors were the presence of ascites (HR, 2.448; 95% CI, 1.142-5.210; P=0.022), serum albumin<3.8g/dL (HR, 3.067; 95% CI, 1.254-8.139, P=0.014), and nonachievement of sustained virologic response (SVR) (HR, 0.066; 95% CI, 0.001-0.484, P=0.002). ConclusionThe incidence of HCC in HCV-related cirrhosis seems to be high in Korea, and advanced liver disease and no achievement of SVR were associated with mortality. The absence of anti-HBs in hepatocarcinogenesis related to HCV warrants further study.
