title: Intrahepatic cholangiocarcinoma and cholangiolocellular carcinoma in cirrhosis and chronic viral hepatitis.
abstract: Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver cancer. Cirrhosis and chronic viral hepatitis are known to be important risk factors for ICC, especially the mass-forming (MF) type of ICC at the periphery of the liver. Cholangiolocellular carcinoma (CoCC) is a rare type of primary liver cancer, which is thought to originate from hepatic progenitor or stem cells. CoCC often exhibits the similar MF type at the periphery of the liver, as ICC, and CoCC is also associated with cirrhosis or chronic viral hepatitis. Better survival rates after surgery have been reported for ICC patients with chronic viral hepatitis than for those without chronic viral hepatitis, although survival rates did not differ significantly in relation to cirrhosis. On the other hand, patients with CoCC had better surgical results than those with MF-type ICC. This review summarizes the clinical characteristics and surgical outcomes of ICC and CoCC associated with cirrhosis or chronic viral hepatitis.
