Background: The phase III trial IMpower133 showed that platinum and etoposide plus atezolizumab was associated with improved overall survival (OS) and progression free‐survival (PFS) when compared to the placebo group in treatment‐naïve extensive stage (ES) small cell lung cancer (SCLC). Due to superiority in clinical outcomes, combination immunotherapy plus chemotherapy have become mainstay treatment modalities as first‐line treatment in ES‐SCLC. Nevertheless, real‐world data are still lacking and the search for potential biomarkers is essential. This study aimed to evaluate potential predictive biomarkers applicable in ES‐SCLC under combination therapy. Methods: Patients with ES‐SCLC under etoposide‐platinum‐atezolizumab enrolled from seven university hospitals affiliated to the Catholic University of Korea were evaluated. Pretreatment clinical parameters were evaluated for association with OS and PFS. Adverse events (AEs) during induction and maintenance phases were also evaluated. p‐values below 0.05 were considered statistically significant. Results: A total of 41 patients were evaluated. Six‐month survival was 68.6%. As best response to treatment, 26 (63.4%) showed partial response, nine (22.0%) showed stable disease, and four (9.8%) showed progressive disease. During the induction phase, grade I–II AEs occurred in 22 (53.7%) patients, and grade III–IV AEs occurred in 26 (63.4%) patients. During the maintenance phase, nine out of 25 (36.0%) patients experienced any grade AEs. In multivariate analysis for OS, lactate dehydrogenase (LDH), c‐reactive protein (CRP), and forced vital capacity (%) were significant factors. In multivariate analysis for PFS, sex, and LDH were significant. Conclusion: In ES‐SCLC under etoposide‐platinum‐atezolizumab, pretreatment CRP, LDH and FVC (%) were independent predictive factors.
