METHOD FOR DETECTING AND DETERMINING INTRAHEPATIC CHOLANGIOCARCINOMA

摘要

Disclosed are a method for early, sensitively and reliably detecting and distinguishing intrahepatic cholangiocarcinoma in a malignant tumor occurring primarily in the liver in a simple way, and a kit therefor. In the method, a glycan biomarker consisting of a lectin WFA (Wisteria floribunda Agglutinin)-binding glycoprotein derived from intrahepatic cholangiocarcinoma is used as a cancer marker to detect intrahepatic cholangiocarcinoma by detecting the cancer marker in a test specimen. The method for detecting intrahepatic cholangiocarcinoma can clearly differentiate intrahepatic cholangiocarcinoma from hepatocellular carcinoma and enables early detection and determination with a performance clinically acceptable in terms of applicability, sensitivity and precision.
