%X <B>UNASSIGNED: </B>Immune checkpoint inhibitor plus platinum-etoposide (PE) improved overall survival (OS) in patients with extensive-stage small cell lung cancer (ES-SCLC). While the CASPIAN trial demonstrated the efficacy of durvalumab plus PE, the clinical trial results may not be representative of the general, real-world population because clinical trials often have strict inclusion and exclusion criteria. We herein report the efficacy and safety of durvalumab plus PE in patients with ES-SCLC in real-world, clinical practice.<BR><B>UNASSIGNED: </B>The present, monocentric, retrospective study evaluated patients with ES-SCLC or recurrent, limited-stage SCLC who received durvalumab plus PE between September 2020 and February 2023. The efficacy and incidence of adverse events (AEs) were also evaluated.<BR><B>UNASSIGNED: </B>The study included 40 patients, of whom 17 were elderly (age >70 years), and 15 had performance status (PS) 2 or 3. The median follow-up time was 13.0 months [95% confidence interval (CI): 8.0-22.2 months]. The objective response rate was 80.0% (95% CI: 63.1-91.6%), and the disease control rate was 88.6% (95% CI: 73.3-96.8%). The median progression-free survival (PFS) was 5.9 months (95% CI: 4.9-6.9), and the median OS was 25.4 months (95% CI: 4.6-46.2). Factors such as advanced age, poor PS, and presence of brain metastases were not associated with lower PFS and OS. Twenty-six patients (65.0%) experienced grade 3 or higher AEs, mainly hematological toxicity. AEs leading to treatment discontinuation occurred in three patients (8%).<BR><B>UNASSIGNED: </B>Durvalumab plus PE in patients with ES-SCLC showed good efficacy and safety according to our real-world data, suggesting that this treatment is well tolerated in clinical practice, even in elderly patients and those with poor PS.
