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

Abstract

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.
