Sex differences in adverse events among cancer patients receiving immune checkpoint inhibitors: the MOUSEION-07 systematic review and meta-analysis
Abstract
Immune checkpoint inhibitors have revolutionized cancer treatment, but they are associated with a range of immune-related adverse events (irAEs), and emerging evidence suggests significant sex differences in the incidence, type, and severity of these toxicities, suggesting an influential factor and understanding sex-related differences in irAEs as crucial for optimizing patient care and improving clinical outcomes. In MOUSEION-07 study, we aimed to assess the association between sex and treatment-related adverse events in cancer patients treated with immunotherapy through a large up-to-date meta-analysis of available clinical trials. The present systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis. The protocol was registered with PROSPERO no. CRD42024549518. Sixteen studies encompassing a total of 4658 patients were included, and 2133 adverse effects were highlighted. The analysis observed a not statistically significant difference in terms of immune-related adverse events (irAEs) between males and females (Odds Ratio 1.19; CI 0.88–1.63) and revealed the presence of publication bias (β = −2.53; 95% CI = [−4.03; −1.04]; P = 0.006). Sex differences in immunotherapy-related adverse events are a significant factor in cancer treatment, necessitating a personalized approach to patient care. Further research is needed to fully understand the mechanisms driving these differences and to develop…
