Prognostic value of preoperative inflammatory markers in resectable biliary tract cancer – Validation and comparison of the Glasgow Prognostic Score and Modified Glasgow Prognostic Score in a Western cohort

Introduction Established preoperative prognostic factors for risk stratification of patients with biliary tract cancer (BTC) are lacking. A prognostic value of the inflammation-based Glasgow Prognostic Score (GPS) and Modified Glasgow Prognostic Score (mGPS) in BTC has been indicated in several Eastern cohorts. We sought to validate and compare the prognostic value of the GPS and the mGPS for overall survival (OS), in a large Western cohort of...
