Prognostic Value of Combined Carbohydrate Antigen 19-9 and Duke Pancreatic Monoclonal Antigen Type 2 Assessment in Biliary Tract Cancer

Key Points

• The aim is to evaluate the prognostic value of combined CA19-9 and DUPAN-2 biomarkers in biliary tract cancer.
• Assessed preoperative levels of CA19-9 and DUPAN-2
• Evaluated outcomes in patients with biliary tract cancer
• Considered the influence of Lewis antigen and FUT3 function on results
• Concurrent normal levels of CA19-9 and DUPAN-2 predicted favorable patient outcomes
• Combined assessment improved prognostic stratification for biliary tract cancers
