[A case of Vp4 hepatocellular carcinoma treated with surgical resection and continuous intrahepatic artery infusion chemotherapy of low-dose cisplatin and 5-fluorouracil].

A 49-year-old woman was admitted to our hospital because of hepatocellular carcinoma (HCC). She had no hepatitis virus. Serum AFP and PIVKA-II levels were as high as AFP 329.4 ng/ml (AFP-L3% 73.1%) and 281 AU, respectively. Portal venous thrombus was observed from the right portal branch to left portal branch and superior mesenteric vein. An extended right hemihepatectomy with extraction of portal venous thrombus was performed. On postoperative day 8, low-dose cisplatin (10 mg/day for 5 days/week) and 5-fluorouracil (250 mg/day for 5 days/week) were administered through the hepatic artery for 4 weeks. After chemotherapy, one intrahepatic metastasis appeared and RFA was performed for this tumor. At 16 months after surgery, she had multiple lymph node metastases and died at 20 months after the surgery without intrahepatic metastasis. Low-dose CDDP/5-FU intra-hepatic artery infusion chemotherapy was effective for prevention of intrahepatic recurrence after resection of HCC with portal venous thrombus.
