PG - 108876 LID - S1521-6616(21)00213-8 [pii] LID - 10.1016/j.clim.2021.108876 [doi] AB - PURPOSE: To evaluate the efficacy and safety of immune checkpoint inhibitor combination therapy in advanced renal cell carcinoma (RCC). METHODS: We searched PubMed/Embase/Cochrane Library for relevant randomized controlled trials (RCTs). Clinical outcome measures including overall survival (OS), progression-free survival (PFS), objective response rates (ORRs), and adverse events (AEs) were analyzed by Stata 15.1 software. RESULTS: Seven RCTs involving 3461 patients were included. The pooled hazard ratios of OS and PFS for combination therapy were 0.67 (0.53-0.82, p < 0.001) and 0.68 (0.52-0.83, p < 0.001), respectively. Longer OS and PFS for combination therapy was also observed in the PD-L1 expression leve >/=1% group. The pooled odds ratios of ORRs and grade 3 or higher AEs were 2.31 (1.61-3.32, p < 0.001) and 0.94 (0.65-1.37, p = 0.753), respectively. CONCLUSIONS: Immune checkpoint inhibitor combination therapy showed more clinical benefit in the first-line treatment for advanced RCC, with a safety profile. CI - Copyright (c) 2021 Elsevier Inc.
