NPS were calculated using preoperative albumin concentration, total cholesterol concentration, neutrophil/lymphocyte ratio, and lymphocyte/monocyte ratio and used to allocate patients into three groups: NTS-0 (0 points), NTS-1 (1-2 points) and NTS-2 (3-4 points). Kaplan-Meier was used to calculate disease-free survival (DFS) and overall survival (OS) in each NPS group and the log-rank test to compare these groups. Univariate and multivariate survival analyes were performed using the Cox regression model. Time-dependent receiver operating characteristic curves were constructed to compare the relationships between four commonly used tools for evaluating inflammatory responses and nutritional status:NPS, systemic inflammatory response scores, nutrient control status (CONUT), and prognostic nutrition index (PNI). <b>Results:</b> The study cohort comprised 221 patients with AEG of median age 63.0 (36.0-87.0) years. There were 190 men (86.0%) and 31 women (14.0%). As to pTNM stage, 47 patients (21.3%) had Stage I disease, 68 (30.8%) Stage II, and 106 (48.0%) Stage III. One hundred and forty-seven patients (66.5%) had Siewert Type II disease and 74 (33.5%) Siewert type III. There were 45 patients (20.4%) in the NPS-0, 142 (64.2%) in the NPS-1 and 34 (15.4%) in the NPS-2 groups. Higher NPS scores were significantly associated with older patients (χ²=5.056, <i>P</i>=0.027) and higher TNM stages (<i>H</i>=5.204,<i>P</i><0.001). The median follow-up was 39 (6-105) months; 16 patients (7.2%) were lost to follow-up. The median OS in the NPS-0, NPS-1, and NPS-2 groups were 78.4, 63.1, and 37.0 months, respectively; these differences are statistically significant (<i>P</i>=0.021). Univariate and multivariate Cox regression analysis identified the following as independently and significantly associated with OS in patients with Siewert Type II-III: TNM stage (Stage II: HR=2.182, 95%CI: 1.227-3.878, <i>P</i>=0.008; Stage III: HR=3.534, 95%CI: 1.380-6.654, <i>P</i><0.001), tumor differentiation (G3: HR=1.995, 95%CI: 1.141-3.488, <i>P</i>=0.015), vascular invasion (HR=2.172, 95%CI: 1.403-3.363, <i>P</i><0.001), adjuvant chemotherapy (HR=0.326, 95%CI: 0.200-0.531, <i>P</i><0.001), NPS (NPS-1: HR=2.331, 95%CI: 1.371-3.964, <i>P</i>=0.002; NPS-2: HR=2.494, 95%CI: 1.165-5.341, <i>P</i>=0.019), SIS group (NPS-1: HR=2.170, 95%CI: 1.244-3.784, <i>P</i>=0.006; NPS-2: HR=2.291, 95%CI: 1.052-4.986, <i>P</i>=0.037), and CONUT (HR=1.597, 95% CI: 1.187-2.149, <i>P</i>=0.038).
