Comparison of Inflammation-based Prognostic Scores in Patients With Biliary Tract Cancer After Surgical Resection.

BACKGROUND/AIM Inflammation-based prognostic scores are proven prognostic biomarkers in various cancers. This study aimed to identify a useful prognostic score for patients with biliary tract cancer (BTC) after surgical resection. PATIENTS AND METHODS This retrospective study recruited 115 patients with BTC during 2010-2020. The relationship between clinicopathological variables, including various prognostic scores and overall survival (OS), was investigated using univariate and multivariate analyses. RESULTS BTC included 58 cholangiocarcinoma, 29 gallbladder carcinoma, 16 ampullary carcinoma, and 12 perihilar cholangiocarcinoma cases. A significant difference was detected in OS of patients with a Japanese modified Glasgow prognostic score (JmGPS) 0 (n=62) and JmGPS 1 or 2 (high JmGPS) (n=53). In the multivariate analysis, tumour differentiation (p=0.014) and a high JmGPS (p=0.047) were independent prognostic factors. CONCLUSION The high JmGPS was an independent prognostic predictor after surgical resection and was superior to other prognostic scores.
