Meta-analysis of efficacy and safety of pembrolizumab for the treatment of advanced or recurrent cervical cancer
This meta-analysis seeks to assess the efficacy and safety of pembrolizumab in individuals with advanced or recurrent cervical cancer. Databases from PubMed, Embase, and the Cochrane Library were all thoroughly searched for pertinent research. Outcomes include complete response (CR), partial response (PR), stable disease (SD), disease progression (PD), overall response rate (ORR), disease control rate (DCR), median progression-free survival (mPFS), median overall survival (mOS), and adverse events (AEs) were retrieved for further analysis. Ten trials with 721 patients were included in this meta-analysis. The pooled results for patients with cervical cancer receiving pembrolizumab were as follows: CR (0.06, 95%CI: 0.02-0.10), PR (0.15, 95%CI: 0.08-0.22), SD (0.16, 95%CI: 0.13-0.20), PD (0.50, 95%CI: 0.25-0.75), ORR (0.26, 95%CI: 0.11-0.41) and DCR (0.42, 95%CI: 0.13-0.71), respectively. Regarding survival analysis, the pooled mPFS and mOS were 3.81 and 10.15 months. Subgroup analysis showed that pembrolizumab in combination was more beneficial in CR (0.16 vs. 0.03, For patients with advanced or recurrent cervical cancer, this systematic review and meta-analysis demonstrated that pembrolizumab had a favourable efficacy and tolerability. Future research will primarily focus on optimising customised regiments that optimally integrate pembrolizumab into new therapies and combination strategies.
