Hylemon, Huiping Zhou – 22 February 2014 – Cholangiocarcinoma (CCA) is an often fatal primary malignancy of the intra‐ and extrahepatic biliary tract that is commonly associated with chronic cholestasis and significantly elevated levels of primary and conjugated bile acids (CBAs), which are correlated with bile duct obstruction (BDO). BDO has also recently been shown to promote CCA progression.
