However, HCC still develop in a portion HCV patients after sustained virologic response (SVR). The aim of present study is to evaluate the

risk factors of HCC development in HCV patients after SVR to peg-IFN combination therapy.Methods: Seven hundred and six CHC patients receiving peg-IFN and oral ribavirin for 24 or 48 weeks who achieving SVR were analyzed from March 2002 to October 2009. Cumulative incidence of HCC was estimated by the Kaplan-Meier method. The prognostic relevance of clinical variables and HCC occurrence was evaluated by univariate analysis with the log-rank test and by multivariate 's regression analysis.Results: During a median follow-up period of 32.9 months , HCC developed in 13 patients with SVR. Cumulative incidence of HCC was 0.8 % in 1-yr, 1.2 % in 3-yr, and 3.0 % in 5-yr. Kaplan-Meier analysis revealed that old age (≥60 years) (P < 0.001), male gender (P=0.013), advanced fibrosis (3-4) (P< 0.001), low platelet count (< 100x109/L) (P < 0.001) and AFP levels (≥ 20ng/ml) (P< 0.001) were associated with HCC occurrence.

Multivariate analysis revealed old age (hazard ratio (HR):12.47, 95% confidence interval (CI): 1.60-96.67), male gender (HR: 5.71, 95% CI: 1.27-25.91), low platelet count (HR: 3.47, 95% CI: 1.13-10.62) and advanced fibrosis (HR: 8.91, 95% CI: 1.11-71.42) were independent risk factors.Conclusions: The current study demonstrated that HCV patients with old age, male gender, advanced hepatic fibrosis, and low platelet count at baseline of HCV therapy need more close follow-up even after SVR to peg-IFN combination therapy.http://www1.easl.eu/easl2011/program/Posters/Abstract215.htm
