Lenvatinib For Hepatocellular Carcinoma Patients With Nonviral Infection Who Were Unlikely To Respond To Immunotherapy: A Retrospective, Comparative Study
ONCOLOGY(2021)
Abstract
Aim: Atezolizumab plus bevacizumab (atezo + bev) shows a good overall survival (OS) in advanced hepatocellular carcinoma (HCC) patients. However, the OS of patients with nonviral infection is quite worse than that in those with viral infection. The present study investigated the efficacy and safety of lenvatinib in patients with nonviral infection, who were unlikely to obtain benefit from atezo + bev. Methods: We conducted a multicenter retrospective study that included 139 advanced HCC patients treated with lenvatinib between March 2018 and September 2020. Results: The median age was 72 years, and 116 patients (83.5%) were male. Based on the etiology of liver disease, 84 (60.4%) and 55 patients (39.6%) were assigned to the viral infection and nonviral infection groups, respectively. The significant extents in patient characteristics were not observed in both groups. The objective response rate per mRECIST and progression-free survival (PFS) did not differ significantly between the viral infection and nonviral infection groups (36.0 vs. 33.0%, p = 0.85; and 7.6 vs. 7.5 months, p = 0.94, respectively). The 1-year survival rates were 68.7% (95% confidence interval [CI] 57.7-79.7%) in the viral infection group and 59.5% (95% CI 45.2-73.8%) in the nonviral infection group. The viral infection group was not a significant factor associated with the PFS or OS in a multivariate analysis. Conclusions: Lenvatinib shows no significant difference in response between patients with and without viral infection. Treatment strategies based on the etiology of liver disease may lead to good clinical outcome.
