Addition of Bevacizumab to Chemotherapy and Its Impact on Clinical Efficacy in Cervical Cancer: A Systematic Review and Meta-Analysis.

: Cervical cancer is the third leading cause of cancer-related mortality in females. One of the most successful therapeutic modalities to date is suppressing vascular endothelial growth factor (VEGF)-mediated angiogenesis. Bevacizumab is a monoclonal antibody that targets VEGF-A. The outcomes for cervical cancer patients treated with bevacizumab in combination with platinum-based chemotherapy have been explored in several studies. This study aimed to assess the impact of bevacizumab on progression-free survival (PFS) and overall survival (OS) in patients with metastatic cervical cancer. : This systematic review was registered in PROSPERO (CRD42023456755). Following PRISMA guidelines, a comprehensive literature search on PubMed and Google Scholar identified 28 studies meeting the inclusion criteria. The outcomes of interest were PFS and OS. The statistical analysis computed hazard ratios (HRs) with 95% confidence intervals (CIs). The study also included a subgroup analysis by cervical cancer stage. : The pooled analysis revealed that bevacizumab-based therapy significantly improved both PFS with HR 0.77 (95% CI: 0.58-0.96; < 0.01; I = 58%) and OS with HR 0.63 (95% CI: 0.45-0.89; < 0.01; I = 41%) in cervical cancer patients. Subgroup analysis by stage of cervical cancer demonstrated better efficacy of bevacizumab in metastatic stage IVB cervical cancer patients indicated by HR for PFS (0.69, 95% CI: 0.54-0.79; < 0.01) and HR for OS (0.57, 95% CI: 0.46-0.73; < 0.01). : Bevacizumab exhibits a significant increase in PFS and OS, underscoring the efficacy of anti-angiogenesis therapy in cervical cancer, particularly in stage IVB metastatic cervical cancer patients.
