Impact of Patients' Gender on Efficacy of Immunotherapy in Patients With Metastatic Kidney Cancer: A Systematic Review and Meta-analysis. Review uri icon

Overview

abstract

  • Recent meta-analyses on checkpoint inhibitors in cancer report conflicting data regarding the association of patient gender with inhibitor efficacy. In advanced kidney cancer, checkpoint inhibitors have shown improved outcomes in first- and second-line settings compared with standard of care, but the role of patient gender on treatment outcome is unclear. We aimed to assess the efficacy of immunotherapy according to patient gender in advanced kidney cancer. We performed a systematic review and meta-analysis according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A literature search was performed using PubMed, Scopus, Web of Science, and The Cochrane Library to identify eligible studies published through February 16, 2019. Studies were included if they reported on the differential outcomes of male and female patients with metastatic kidney cancer receiving immunotherapy. Our outcomes of interest were overall survival (OS) or progression-free survival (PFS). Four randomized controlled trials comprising a total of 3664 patients (2715 males and 949 females) met our inclusion criteria. Both men and women with metastatic kidney cancer had an OS and PFS advantage with immunotherapy compared with standard-of-care, but no statistically significant difference between the genders was observed (OS hazard ratio [HR] for men, 0.69; 95% confidence interval [CI], 0.59-0.8; P = .40; HR for women, 0.62; 95% CI, 0.48-0.81; P = .13; PFS HR for men, 0.7; 95% CI, 0.59-0.82; P = .24; HR for women, 0.68; 95% CI, 0.52-0.90; P = .105). In patients with advanced kidney cancer receiving checkpoint inhibitors, there seems to be no association of patient gender with treatment outcome.
