METHOD FOR DETECTING AND DETERMINING INTRAHEPATIC CHOLANGIOCARCINOMA

摘要

Disclosed is a method for detecting and determining intrahepatic cholangiocarcinoma, which is a malignant tumor primarily occurring in the liver, in the early stage in a simple manner with high sensitivity and high reliability. Also disclosed is a kit for achieving the method. In the method, intrahepatic cholangiocarcinoma can be detected by detecting a cancer marker in a sample, wherein the cancer marker is a sugar chain biomarker comprising a lectin WFA (wisteria fioribunda agglutinin)-binding glycoprotein derived from intrahepatic cholangiocarcinoma. The intrahepatic cholangiocarcinoma detection method enables the clear distinction of intrahepatic cholangiocarcinoma from hepatocellular carcinoma, and also enables the detection and determination of intrahepatic cholangiocarcinoma in the early stage with clinically acceptable applicability, sensitivity and accuracy.
