Blood glucose has been demonstrated to serve as prognostic indicators in various malignancies. This study aimed to explore the relationship between fasting blood glucose (FBG) levels and the prognosis in patients with gastrointestinal stromal tumor (GIST) undergoing complete resection. Data were retrospectively collected from 256 patients with primary GIST underwent complete surgical resection or endoscopic excision. Patients were stratified into euglycemic group and hyperglycemic group. Patients' characteristics between groups were compared. Cox regression model was conducted to identify independent prognostic factors of disease-free survival (DFS). Both univariate analysis and multivariate analyses revealed that FBG ≥ 100 mg/dl was associated with poor outcomes. Patients with FBG ≥ 100 mg/dl tended to have more adverse features, more likely to suffer recurrence and a worse 5-year DFS than patients with FBG < 100 mg/dl. Moreover, FBG levels helped distinguishing between patients with different survival outcomes in different risk categories defined by modified NIH systems. Our data provided the evidence that FBG is a useful prediction marker prognosis in patients with GIST undergoing curative surgery.
