Significance of the Glasgow prognostic score for short-term surgical outcomes: A nationwide survey using the Japanese National Clinical Database.

Aim: Preoperative inflammation-based Glasgow prognostic score (GPS) is a useful tool for predicting long-term prognosis in cancer patients. However, its association with postoperative short-term outcomes remains unknown. The aim of this study is to investigate the association between GPS and postoperative morbidity and mortality among patients undergoing surgery for various gastrointestinal malignancies.
