Hepatitis C virus eradication prolongs overall survival in hepatocellular carcinoma patients receiving molecular-targeted agents.

BACKGROUND: The aim of this multicenter retrospective study was to evaluate the impact of the eradication of hepatitis C virus (HCV) on the clinical outcomes of patients with hepatocellular carcinoma (HCC) treated with molecular-targeted agents (MTAs). METHODS: Among 877 patients who received any MTA as first-line systemic therapy for HCC between June 2009 and March 2019, 569 patients with HCV-related HCC were enrolled in this retrospective study. Of these, 109 patients achieved sustained virological response (SVR) before starting MTA. After propensity score matching, the clinical outcomes of 109 patients in the SVR group and 109 patients in the non-SVR group were compared. RESULTS: The median time to progression in the SVR group (7.8 months) was similar to that in the non-SVR group (5.6 months) (p = 0.212). The median time to treatment failure in the SVR group (5.3 months) was longer than that in the non-SVR group (2.8 months) (p = 0.059), and post-progression survival and overall survival in the SVR group were significantly longer than those in the non-SVR group (12.0 months vs 7.2 months; p = 0.039, and 18.1 months vs 11.3 months; p = 0.019). At the end of first-line MTA therapy, the albumin-bilirubin (ALBI) score in the SVR group ( - 2.25) was significantly lower than that in the non-SVR group ( - 2.10) (p = 0.008). CONCLUSIONS: The eradication of HCV before MTA therapy maintained liver function and led to a prolonged treatment period and improved overall survival of HCV-related HCC patients. We should not overlook the benefits of HCV eradication in HCC patients.
