Locally Advanced Intrahepatic Cholangiocarcinoma Successfully Resectedafter Transcatheter Arterial Chemoembolizationwith Degradable Starch Microspheres:Report of a Case

摘要

We describe a case of initially unresectable locally advanced intrahepatic cholangiocarcinoma that showed remarkable regression after transcatheter arterial chemoembolization with degradable starch microspheres, allowing for subsequent successful curative resection. A 75-year-old female was referred to our hospital with a large hepatic mass. Computerized tomography examination showed a huge mass in the right liver extended partially to the left liver. Intrahepatic cholangiocarcinoma was strongly suspected, but surgical resection was abandoned due to the local spread in the liver. Three courses of transcatheter arterial chemoembolization with degradable starch microspheres were performed. The anti-cancer agents, mitomycin C and epirubicin, combined with degradable starch microspheres were injected from the catheter for chemoembolization. After three courses of transcatheter arterial chemoembolization, the tumor size decreased from 10cm to 5.5cm in diameter. Then right trisegmentec-tomy together with extra-hepatic bile duct excision was performed. At 25 months after the first therapy and 21 months after operation, the patient remains healthy without recurrence. Transcatheter arterial chemotherapy with degradable starch microspheres may be a treatment of choice with locally advanced intrahepatic cholangiocarcinoma.
