Intrahepatic cholangiocarcinoma: Intrahepatic cholangiocarcinoma, i.e. cholangiocarcinoma, refers to cancer occurring in the intrahepatic cholangiocarcinoma (i.e. above the 1st intrahepatic branch of the left and right hepatic ducts) and is a kind of primary liver cancer. Clinical symptoms vary depending on the site of occurrence. Terminal cholangiocarcinoma is asymptomatic in the early stage, and may have epigastric discomfort, hepatomegaly and weight loss in the late stage; cholangiocarcinoma of the hilar region often has jaundice as the initial symptom. The prognosis of cholangiocarcinoma is very poor. Without any surgery and drainage, most of them die within 3 months after making the diagnosis. The 1-year and 3-year survival rates for more complete tumor resection are 90% and 40%, respectively. While the palliative surgery is only at 55% and 10%. Advanced patients with drainage alone rarely survive longer than 1 year.
