Efficacy and Safety of Nivolumab for Advanced Renal Cell Carcinoma: A Systematic Review and Meta-Analysis

Abstract

Objective. To assess the efficacy and safety of nivolumab for advanced renal cell carcinoma (RCC) via meta-analysis. Methods. In this systematic review and meta-analysis, we searched PubMed, Embase, Science Citation Index Expanded, The Cochrane Library, and Web of Science for randomized controlled trials (RCTs) using nivolumab for patients with advanced RCC published before 30 December 2021. Quality assessments and meta-analyses were performed on all the literature assessed for eligibility. Results. Of 203 studies identified as potentially eligible from 3214 studies in a preliminary search, three RCTs including 2550 RCC cases met the inclusion criteria and were of high quality. Meta-analysis showed benefits of nivolumab in the progression-free survival (PFS) (HR = 0.73, 95% CI: 0.54 to 0.99, $P=0.04$ ) and overall survival (OS) (HR = 0.70, 95% CI: 0.63 to 0.78, $P<0.001$ ) of patients with advanced RCC, and no increase in documented adverse events was recorded. Conclusion. Nivolumab plus ipilimumab has significant benefits versus sunitinib in the treatment of advanced RCC in terms of tumor progression control and prolongation of OS and PFS, with a manageable safety profile.
