Navigating first-line therapies for extensive-stage small-cell lung cancer: a frequentist network meta-analysis and...

Aim: To identify the optimal first-line treatment for patients with extensive-stage small-cell lung cancer (ES-SCLC).Materials & methods: We conducted a network meta-analysis (CRD42023486863) to systematically evaluate the efficacy and safety of eight first-line treatment regimens for ES-SCLC, including 15 clinical trials.Results: Our analysis showed that the PD-1/PD-L1 + etoposide combined with platinum (EP) and PD-L1 + vascular endothelial growth factor (VEGF) + EP regimens significantly enhanced overall survival and progression-free survival, with subgroup analysis revealing that serplulimab ranked as the most promising option for improving overall survival. Integrating anti-angiogenesis drugs into immunochemotherapy presents potential benefits, with an increased incidence of adverse events necessitating further investigation.Conclusion: Our findings offer valuable insights for future research and for developing more effective treatment strategies for ES-SCLC, underscoring the critical need for continued innovation in this therapeutic area.
