Background:Locally advanced non-small cell lung cancer (NSCLC) is often associated with unfavorable clinical outcomes. This study aims to examine the association between peripheral immuno-inflammatory biomarkers, the effectiveness of radiotherapy, and 1-year survival rates in stage III NSCLC. Materials and Methods: This study reviewed 180 stage III NSCLC patients treated with radical radiotherapy from 2020 to 2024. Pretreatment neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune inflammation index (SII), and lymphocyte-to-monocyte ratio (LMR) levels were measured and compared with healthy controls. Biomarker differences were analyzed across clinical subgroups and between radiotherapy response groups. Using median values as cutoffs, one-year survival data were assessed, with Cox regression determining prognostic factors. Results: Patients with NSCLC had significantly higher NLR, PLR, and SII and lower LMR than the control group (P<0.05). The good-response group had lower NLR, PLR, and SII and higher LMR (P<0.05). Higher NLR, PLR, and SII were associated with worse 1-year survival, while higher LMR predicted better outcomes (P<0.05). Cox analysis confirmed that all four markers were independent prognostic factors (P<0.05). Conclusion: The peripheral blood markers NLR, PLR, SII, and LMR are closely associated with radiotherapy efficacy and 1-year survival in stage III NSCLC.
