Prognostic Value of Modified Glasgow Prognostic Score (mgps) and Neutrophil-Lymphocyte Ration (NLR) after Curative Resection for Gastric Cancer

295 Background: Several biomarkers based on serum chemistry have been reported to be associated with the prognosis of several types of cancers. This retrospective study aimed to investigate the prognostic value of preoperative mGPS and NLR after curative resection for gastric cancer. Methods: A total of 295 patients who underwent curative gastrectomy for primary gastric cancer at our institution from January 2013 to December 2017 were enrolled in this study. The mGPS was calculated by CRP and Alb using standard thresholds ( > 0.5 mg/dL for CRP and < 3.5 g/dL for Alb). The NLR was defined as absolute neutrophil count divided by absolute lymphocyte count. The survival curves of patients stratified by each parameter were plotted by the Kaplan-Meier method and compared by log-rank test. Multivariate Cox proportional hazards regression models were used to select parameters independently correlated with prognosis. Results: The median follow-up time was 36.7 months, and 29 patients died during follow-up. The estimated 5-year survival rate was 83.1%. Results from the univariate analyses showed mGPS2 (CRP > 0.5 mg/dL and Alb < 3.5 g/dL) was associated with poor survival while NLR and NLRc was not (P < 0.001, P = 0.506, and P = 0.423, respectively). In the multivariate analyses, the mGPS2 was identified as an independent predictive factor for OS in gastric cancer patients after curative resection (HR: 2.624; 95% CI: 1.058-6.505; P = 0.037). Conclusions: Preoperative mGPS2 was associated with worse survival after curative resection of gastric cancer patients. Based on our study, those with mPGS2 may be warranted to receive additional therapy or nutritional support to acquire better survival.
