Efficacy and Safety of Sorafenib or Lenvatinib for Advanced Hepatocellular Carcinoma after Failure of First-Line Atezolizumab Plus Bevacizumab: A Systematic Review and Meta-Analysis.

BACKGROUND

Although atezolizumab plus bevacizumab (hereinafter, atezolizumab-bevacizumab) is the standard first-line treatment for patients with advanced HCC, the optimal second-line regimen remains unknown. This study evaluated the efficacy and safety of sorafenib and lenvatinib in patients with advanced HCC that progressed under atezolizumab-bevacizumab treatment.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we searched PubMed, Embase, and the Cochrane Library for articles published before November 2023. Random-effects meta-analysis was performed to determine the pooled objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS), comparing patients who received sorafenib versus lenvatinib.

RESULTS

Seven studies involving 387 patients were included. The pooled ORR, DCR, OS, and PFS for sorafenib and lenvatinib together were 26% (95% CI: 14-43%), 63% (95% CI: 47-77%), 11.45 months (95% CI: 7.12-15.77, = 92%, < 0.01), and 3.78 months (95% CI: 2.34-5.23, = 67%, = 0.02), respectively. Although lenvatinib users had a longer median OS (12.42 vs. 10.75 months) and PFS (5.15 vs. 2.58 months) than sorafenib users, the pooled ORR, DCR, median OS, and PFS for these medications were comparable. Additionally, the distributions of all-grade and grade ≥ 3 adverse events for sorafenib and lenvatinib were comparable to those for these two medications when used as first-line therapies.

CONCLUSIONS

Sorafenib or lenvatinib can provide effective treatment with manageable toxicity in patients with advanced HCC after disease progression under atezolizumab-bevacizumab.
