Core Tip

Core Tip: Distal cholangiocarcinoma (DCC) is a rare malignant tumor in the digestive system and has a poor long-term prognosis. Curative resection is currently the best treatment for patients with DCC because of the lack of effective adjuvant therapies. Therefore, it is important to accurately predict the prognosis for formulating a reasonable treatment plan and avoiding unnecessary surgical trauma. Carbohydrate antigen 19-9 to serum γ-glutamyltransferase (CA19-9/GGT) ratio was adapted as an indicator to minimize the interference of obstructive jaundice CA19-9 level, to determine the strong associations between CA19-9/GGT and postoperative neoplasm recurrence and long-term outcome of DCC.
