RESUMO
Hepatitis C virus (HCV) is one of the major etiologies of hepatocellular carcinoma with approximately 30% of HCC being due to HCV infection worldwide. HCV eradication by antivirals greatly reduces the risk of HCC; nevertheless, HCC remains to occur in CHC patients who have achieved a sustained virological response (SVR). The proportion of post-SVR HCC among newly diagnosed HCC patients is increasing in the DAA era and might be due to preexisting inflammatory and fibrotic liver background, immune dysregulation between host and virus interaction, as well as host epigenetic scar, genetic predispositions and alternations. By means of applying surrogate markers and adopting risk stratification, HCC surveillance should be consistently performed in high-risk populations. In this review, we discuss the possible molecular mechanism, risk factors and surveillance strategy for HCC development after HCV eradication.
