Hepatocellular Carcinoma in Primary Biliary Cholangitis.

Hepatocellular carcinoma (HCC) is potentially fatal complication affecting patients with primary biliary cholangitis (PBC). The incidence of HCC is 13 per 1000 person-years in patients with PBC cirrhosis, but much lower at 2.7 per 1000 person-years among patients with PBC without cirrhosis. Risk factors for the development of HCC in PBC include the presence of advanced fibrosis or cirrhosis and male sex, with some studies suggesting that treatment with ursodeoxycholic acid (UDCA) and UDCA response may reduce risk.
