ObjectivesTo systematically review the efficacy and safety of anti-PD-1/PD-L1 antibody in the treatment of advanced non-small cell lung cancer (NSCLC).MethodsNon-comparative binary data on anti-PD-1/PD-L1 monoclonal antibodies in the treatment of advanced NSCLC from PubMed, EMbase and The Cochrane Library databases were collected from inception to August 1st 2017. Two reviewers screened literature, extracted data and independently evaluated the risk of bias of included studies, then meta-analysis was conducted by RevMan 5.3 software.ResultsForty-four trials were included. The results of meta-analysis showed that the pooled objective response rate (ORR), overall 1-year survival rate (OSR1 year) and progression-free survival rate at 1 year (PFSR1 year ) of anti-PD-1/PD-1 antibodies were 22% (RD=0.22, 95%CI 0.20 to 0.25, P<0.001), 54% (RD=0.54, 95%CI 0.46 to 0.63,P<0.001) and 27% (RD=0.27, 95%CI 0.20 to 0.33,P<0.001), respectively. The rate of adverse effects (AEs) was 61% (RD=0.61, 95%CI 0.54 to 0.68,P<0.001), and the rate of grade 3 to 5 AEs was 13% (RD=0.13, 95%CI 0.10 to 0.15,P<0.001).ConclusionsAnti- PD-1/PD-1 antibodies show good efficacy and safety in the treatment of advanced NSCLC. Due to limited quality and quantity of included studies, more high-quality studies are needed to verify the above conclusions.
