Preoperative NAR values were calculated using neutrophil count and serum albumin levels obtained within 24 hours of admission. Patients were stratified into high-NAR and low-NAR groups using an optimal cut-off value determined by receiver operating characteristic analysis. Kaplan-Meier curves, univariate, and multivariate Cox regression analyses were used to evaluate overall survival and recurrence-free survival.Results: The optimal NAR cut-off value was identified as 2.8. Patients with high NAR exhibited significantly worse overall survival and recurrence-free survival compared to the low-NAR group. High NAR was significantly associated with advanced tumor stage, incomplete resection status, administration of chemotherapy and radiotherapy, and poor histological differentiation (all P < 0.0001). Multivariate analyses confirmed NAR as an independent prognostic factor for both overall survival (HR=2.67; 95% CI, 1.97– 4.25; p = 0.002) and recurrence-free survival (HR=3.51; 95% CI, 1.58– 5.26; p = 0.003).Conclusion: The preoperative neutrophil-to-albumin ratio is an independent and reliable prognostic biomarker for overall and recurrence-free survival in patients with advanced gastric cancer undergoing radical gastrectomy. Due to its accessibility, simplicity, and predictive value, the neutrophil-to-albumin ratio can effectively facilitate risk stratification, personalized clinical decision-making, and targeted interventions to improve patient outcomes.Keywords: gastric cancer, neutrophil-to-albumin ratio, prognostic biomarker, radical gastrectomy, systemic inflammation |
