Clinical study of lenvatinib in the treatment of hepatitis virus-related hepatocellular carcinoma and antiviral therapy.

Abstract

Background: Lenvatinib is recommended as a first-line tyrosine kinase inhibitor for advanced hepatocellular carcinoma (HCC) since 2017. The aim of this study was to compare the clinical action of lenvatinib in hepatitis B virus (HBV)-related HCC and hepatitis C virus (HCV)-related HCC. Methods: A continuous cohort of advanced HCC was retrospectively enrolled. And the patients were divided into HBV-related HCC and HCV-related HCC based on previous history of hepatitis virus infection. Then propensity score matching (PSM) was conducted to compare objective response rate (ORR),disease control rate (DCR),progression-free survival (PFS),overall survival (OS) and safety between the two groups. Results: A total of 203 eligible patients were included, with 72 HBV-related HCC and 36 HCV-related HCC after PSM. Both ORR (20.8% vs. 5.6%, P = .0759) and DCR (76.4% vs. 52.8%, P = .0232) were significantly higher in the HBV-related HCC than in the HCV-related HCC. Although no statistical differences in PFS (6.1months vs. 3.3months, P = .17) and OS (14.9months vs. 17.7months, P = .96) were observed between the two groups, there was a trend of difference in the PFS survival curve. On multivariate regression analysis of PFS, both HBV infection (HR, .54; 95% CI, .31-.95; P = .0332) and antiviral time >5years (HR, .49; 95% CI, .26-.9; P = .0219) were identified as independent favorable factors, and AFP >200ng/mL (HR, 1.88; 95% CI, 1.1-3.22; P = .0216) were found to be an independent adverse factor. In addition, compared with HCC who received the first dose of antiviral drugs less than 5years, the patients who were administered those drugs over 5years had a significantly favorable PFS (11.27months vs. 3.87 months, P = .0011). Lenvatinib was well tolerated in all patients and the adverse events (AEs) were similar between the two groups. Conclusion: It seemed that lenvatinib benefited more in HBV-related advanced HCC in delaying disease progression, compared to those with HCV-related advanced HCC.
