Popis: Purpose: to investigate the prognostic utility of the prognostic nutritional index (PNI) in stage IIIB non-small-cell lung carcinoma (NSCLC) patients undergoing concurrent chemoradiotherapy (CRT). Methods: a total of 358 stage IIIB NSCLC patients who received a total dose of 60-66 Gy (2 Gy/fraction) radiotherapy and >= 1 cycle(s) of platinum-based chemotherapy were analyzed. The receiver operating curve analysis was utilized to identify the optimal PNI cut-off value demonstrating a significant connection with the overall survival (OS), locoregional progression-free survival (LRPFS), and progression-free survival (PFS). Results: at a median follow-up time of 22.5 months (range: 2.4-123.5), 30.2% and 14% of the patients were still alive and free of disease progression, respectively.The median OS, LRPFS, and PFS were 25.2 [95% confidence interval (CI): 36.3-46.6 months], 15.4 (95% CI: 26.6-35.3 months), and 10.7 (95% CI: 36.8-69.9 months), individually, for the whole study accomplice. The ROC analysis revealed an optimum rounded cut-off that associated meaningfully with each of the OS [area under the curve (AUC): 84.1%; sensitivity: 75.9%;72.4% specificity], LRPFS (AUC: 92.4%; sensitivity: 87.9%; 85.1% specificity), and PFS (AUC: 80.1%; sensitivity: 73.7%; 71.6% specificity) at a value of 40.5. Comparative analyses revealed that the patients presenting with PNI 40.5. In univariate analyses, lower T-stage (1-2 vs 3-4; P< 0.001), lower N-stage (N2 vs N3; P< 0.001), anemia status (absent vs present; P< 0.001), weight loss status (= 5%; P< 0.001), and PM group (40.5; P
