Hepatocellular carcinoma (HCC) is one of the cancers with poor prognosis. Especially potal vein invasion is a grave prognostic indicator in the setting of HCC. There is currently no effective method for treatment of HCC with portal vein invasion. A 61-year-old female patient was diagnosed a massive HCCs in both hepatic lobe with portal vein thrombosis, based on computed tomography (CT) and increased tumor marker, α-fetoprotein. She was treated with intrahepatic arterial CDDP (10 mg on 1~5 day), 5-FU (250mg on 1~5 day) and leukovorin (12mg on 1~5 day) infusion via percutaneously implantable port system (PIPS) every 3 weeks, totally seven times. The patient was still living 6 months after first hepatic arterial infusion chemotherapy (HAIC) and follow-up CT showed partial response with necrosis of HCCs. We report here a case of advanced HCC with portal vein thrombosis that was effectively treated with HAIC via PIPS.
