New perspectives in hepatocellular carcinoma surveillance after hepatitis C virus eradication.

Achieving a sustained virologic response (SVR) through direct-acting antivirals for hepatitis C virus (HCV) infection significantly reduces the long-term risk of hepatocellular carcinoma (HCC), particularly in patients with advanced fibrosis (F3) or cirrhosis (F4). However, despite this improvement, the risks associated with HCC and the optimal surveillance strategies for patients who have achieved SVR remain topics of debate. This controversy is compounded by challenges in reliably staging liver fibrosis non-invasively, especially at advanced fibrosis (F3), and the unclear cost-effectiveness, modality, frequency, and duration of HCC surveillance in individuals with SVR but without cirrhosis. These factors contribute to significant variations in surveillance guidelines recommended by different professional societies. Therefore, there is a pressing need for an optimal surveillance strategy that is both simplified and cost-effective to facilitate wider adoption by clinicians. This review article evaluates the existing data, addresses ongoing controversies, and aims to provide new perspectives on HCC surveillance strategies for patients who have achieved SVR from HCV.
