The bile duct is a network of tubes\nthat carry bile from the liver and gallbladder to the small intestine. Tumors that start in bile\nduct branches that lie inside the liver are called intrahepatic bile duct cancer, while those that\nform outside the liver are called extrahepatic bile duct cancer. About 10% of all cholangiocarcinoma\nare intrahepatic and 90% are extrahepatic. TCGA studied both subtypes of cholangiocarcinoma.\n Although cholangiocarcinoma is a rare cancer, the incidence and mortality rates for the disease\nhave been increasing worldwide in the last three decades. Between 2,000 and 3,000 Americans are\ndiagnosed with cholangiocarcinoma each year, the majority of them with tumors at advanced stages.\nThis cancer is more prevalent in Asia and the Middle East, where parasitic infection of the bile\nduct increases the risk of cholangiocarcinoma. Other diseases of the bile duct or liver, such as\nbile duct stones and liver disease, obesity, diabetes, and smoking are also risk factors. When\nintrahepatic and extrahepatic cholangiocarcinoma spread to other parts of the body, only 2% of\npatients survive five years after diagnosis.\nPlease see the\n DICOM converted Slide Microscopy images for the TCGA-CHOL collection (https://doi.org/10.5281/zenodo.12689990)\n page to learn more about the histopathology\nimages and to\nobtain any supporting metadata for this collection.","patients":51,"studies":51,"series":110,"instances":531,"size_TB":0.1,"modalities":["SM"],"licenses":[{"license_short_name":"CC BY 3.0","series":110,"size_TB":0.1}]}
