Abstract Introduction Chemoimmunotherapy is widely used as the first‐line management of advanced non‐small cell lung cancer (NSCLC) in clinical settings. However, predictive factors associated with the development of immune‐related adverse events (irAEs) and prognostic factors for NSCLC patients undergoing chemoimmunotherapy remains largely unexplored. Therefore, in this study, we aimed to evaluate predictive factors for irAE development and prognostic factors associated with chemoimmunotherapy in NSCLC patients. Methods This study enrolled 199 patients with advanced and recurrent NSCLC who underwent chemoimmunotherapy across eight institutions in Nagano prefecture from December 2018 to January 2023. We examined predictive factors associated with irAE development and prognostic factors associated with overall survival (OS). Results Among the patients, 106 experienced irAEs, while 93 patients did not. A total of 44 (22.1%) patients developed multiple irAEs. High serum albumin levels (Alb >3.5 g/dL) emerged as an independent predictive factor associated with irAE development in logistic regression analysis (odds ratio; 2.35, 95% confidence interval 1.27–4.34, p = 0.007). Furthermore, the development of multiple irAEs (p = 0.016), lower lactate dehydrogenase level (<223 U/L, p = 0.002), and decreased neutrophil‐to‐lymphocyte ratio (<3, p = 0.049) were identified as independent favorable prognostic factors associated with OS in multivariate Cox hazard analyses. Conclusion The study results suggest that high serum Alb is a predictive factor for irAE development and that the presence of multiple irAEs is a favorable prognostic indicator for NSCLC patients undergoing chemoimmunotherapy.
