Abstract Background Chemotherapy has been confirmed as an effective treatment for advanced cervical cancer. However, whether combining PD-1/PD-L1 inhibitors with chemotherapy (PIC) offers superior efficacy remains a subject of debate. This meta-analysis aims to compare the antitumor effects and safety profile of PIC versus chemotherapy. Methods We conducted a comprehensive search across six databases to identify eligible randomized controlled trials (RCTs). The primary outcomes assessed were overall survival (OS) and progression-free survival (PFS), while the secondary endpoints included response rates and adverse events (AEs). Results Four RCTs (BEATcc, CALLA, KEYNOTE-826, and KEYNOTE-A18) analyzing 2,857 patients were included. The PIC regimen notably enhanced OS (hazard ratio [HR]: 0.70 [0.61, 0.80], P
