Abstract


Background: The Glasgow prognostic score (GPS) has been reported as a sensitive prognostic marker for gastric cancer. This study aimed to investigate whether the GPS is equally applicable to patients with early-stage and advanced-stage gastric cancers.

Methods: Patients (n = 544) who underwent elective gastrectomy for gastric cancer between 2007 and 2015 were retrospectively studied. GPSs of 2, 1, and 0 were allocated to patients with both an elevated C-reactive protein level (> 1.0 mg/dL) and hypoalbuminemia (< 3.5 mg/dL), patients with only one of these abnormalities, and patients with neither abnormality, respectively. The prognostic factors relevant to patients with early-stage (pStage I, n = 304) and advanced-stage (pStage II, III, and IV, n = 240) gastric cancer were analyzed through univariate and multivariate analyses.

Results: In the early-stage group, only the serum carbohydrate antigen (CA) 19-9 level (P = 0.037) was a significant prognostic factor in the multivariate analysis; the GPS was not significant (P = 0.095). In the advanced-stage group, an American Society of Anesthesiologists physical status of 3 or 4 (P = 0.032), elevated carcinoembryonic antigen (CEA) (P = 0.043) and CA19-9 (P = 0.045) levels, a GPS 1 - 2 (P = 0.017), and type 4 tumor (P = 0.020) correlated significantly with worse overall survival.

Conclusions: GPS is a simple and useful prognostic score for patients with advanced-stage, but is not applicable to early-stage patients.
