[Clinical Features and Treatment for Cholangiolocellular Carcinoma(CoCC)-Report of Three Cases]

We report 3 cases of cholangiolocellular carcinoma(CoCC)experienced from April 2017 to March 2021 in our hospital. The average age of the cases is 74.3 years old, 2 males and 1 female respectively. Hepatectomy was performed in 2 cases, and transcatheter arterial embolization(TAE)and radiofrequency ablation(RFA)therapy was performed in 1 case because of old age and his wishes as the background liver disease. Chronic hepatitis C was found in 1 case, fatty liver in 1 case, and alcoholic liver disease in 1 case. Two patients who underwent hepatectomy had good long-term prognosis, but another patient who underwent TAE and RFA developed early recurrence at bone and died in 3 months after treatment. Therefore, we consider that the risk of recurrence should be examined and the treatment should be performed accordingly.
