Abstract
Background
Atezolizumab plus bevacizumab and lenvatinib are the current first-line systematic therapy for unresectable hepatocellular carcinoma (uHCC). However, the selection of initial treatment among the two therapies are controversial. This meta-analysis aims to compare efficacy and safety between atezolizumab plus bevacizumab and lenvatinib.
Methods
We systematically searched for studies on atezolizumab plus bevacizumab and lenvatinib in the online databases PubMed, Embase, Web of Science and Cochrane Library. The outcome data including overall survival (OS), progression free survival (PFS), tumor response and adverse events (AEs), were independently extracted by two authors in a standardized way.
Results
Eight retrospective cohort studies with 3690 patients (atezolizumab plus bevacizumab: 1680, lenvatinib: 2010) were included in the meta-analysis. The atezolizumab plus bevacizumab group had significant longer PFS [hazard ratio (HR) 0.76, 95% confidence intervals (CI) 0.65–0.88; I squared statistic (I2) = 0.0%, p = 0.590], compared with lenvatinib group but no significant difference in OS (HR 0.87, 95% CI 0.75–1.01; I2 = 0.0%, p = 0.597), objective response rate (ORR) [risk ratio (RR) 0.89, 95% CI 0.79–1.02; I2 = 19.3%, p = 0.283] and disease control rate (DCR) (RR 1.03, 95% CI 0.98–1.09; I2 = 0.0%, p = 0.467) among them. Moreover, patients receiving atezolizumab plus bevacizumab exhibited lower incidences of grade 3/4 AEs than those receiving lenvatinib (RR 0.65, 95% CI 0.51–0.83; I2 = 69.3%, p = 0.003). However, in non-viral patients group, lenvatinib delivered favorable outcomes in OS (HR 1.32, 95% CI 1.04–1.67; I2 = 0.0%, p = 0.380) compared with atezolizumab plus bevacizumab.
Conclusion
Atezolizumab plus bevacizumab provides potential advantage in efficacy and better safety than lenvatinib in the treatment of uHCC. Lenvatinib is an appropriate effective alternative to atezolizumab plus bevacizumab in patients without viral infecting.
