Simple score to predict risk of hepatocellular carcinoma in chronic hepatitis C patients with advanced fibrosis after pegylated interferon and ribavirin therapy

Eradication of chronic hepatitis C virus (HCV) after interferon-based therapy and its association with the reduction of risk of hepatocellular carcinoma (HCC) in HCV-infected patients with advanced fibrosis is controversial. The study is aimed to develop a simple scoring model for HCC prediction among advanced fibrotic chronic hepatitis C (CHC) patients after pegylated interferon (pegIFN) and ribavirin (RBV) therapy. We enrolled 271 biopsy-proven CHC patients with advanced fibrosis between 2003 and 2016, and divided them into non-HCC (n=211) and HCC (n=60) groups. The median observation duration was 6.0 years (range: 0.9-12.6 years). The HCC prevalence after pegIFN and RBV therapy in CHC patients with sustained virologic response (SVR) and without SVR was 14.7% and 32.2%, respectively. Multivariate Cox regression showed age ≥59.5 years old at initiation of therapy (HR: 2.542, 95% CI: 1.390-4.650, =0.002), pretreatment total bilirubin ≥1.1 mg/dL (HR: 2.630, 95% CI: 1.420-4.871, =0.002), pretreatment platelet counts
