Abstract

The aim of this study was to evaluate the significance of the Glasgow prognostic score (GPS) in patients with resected gastrointestinal stromal tumors (GISTs). Forty-six GIST patients who underwent radical resection between January 2004 and December 2011 were enrolled in this retrospective study. The clinicopathological parameters examined included predictors of recurrence-free survival (RFS). Univariate and multivariate analysis of prognostic factors related to RFS were calculated using Cox proportional hazards model. The GPS classification system revealed 37 (80.4%), 6 (13.1%), and 3 (6.5%) patients with a GPS of 0, 1, and 2, respectively. Patients with GPS 1/2 had a significantly shorter RFS compared to those with GPS 0 (P = 0.01). The 3- and 5-year RFS rates for patients with GPS 0 were 94.0% and 90.9%, respectively, compared to 66.7% and 53.3%, respectively, for patients with GPS 1/2. Univariate analyses indicated that tumor size (P < 0.01), mitotic rate (P < 0.01), higher GPS (P < 0.01), and platelet count (P = 0.04) were prognostic factors for RFS; tumor size (P = 0.01) and GPS (P = 0.04) were independent prognostic factors in multivariate analysis. Preoperative high GPS were predictors of long-term prognosis in patients with resected GISTs.
