Successful treatment of combined intraarterial (5-fluorouracil and adriamycin and cisplatin) infusion chemotherapy for advanced hepatocellular carcinoma with multiple intrahepatic metastases and/or portal vein thrombosis--two case reports

Hepatic arterial infusion chemotherapy has been often selected as a therapeutic option for advanced hepatocellular carcinoma with multiple intrahepatic metastases and/or portal vein thrombosis. We successfully treated and obtained CR in the 2 cases of far advanced hepatocellular carcinoma with intraarterial infusion chemotherapy (FAP). Case 1 was a 71-year-old male who had advanced hepatocellular carcinoma with intrahepatic metastasis (IM3) which was recurrent after two surgeries. He received hepatic arterial infusion chemotherapy (FAP: 5-fluorouracil 500 mg/day: continuous infusion, day 1-5, adriamycin 10 mg/day, day 1, CDDP 10 mg/day, day 1). After 10 courses, abdominal CT revealed that the viable lesions had completely disappeared (CR). This patient is still alive with no recurrence after 21 months from the beginning of this treatment. Case 2 was a 74-year-old male who had advanced hepatocellular carcinoma with portal vein thrombi (Vp4) and intrahepatic metastasis (IM3). He received FAP arterial infusion chemotherapy with the same protocol as case 1. After 8 courses of this therapy, CT revealed that these lesions had disappeared (CR). This patient is still alive with no recurrence after 9 months from the beginning of this treatment. For 15 patients with advanced hepatocellular carcinoma using a same protocol, the response rate of this therapy was 33.3% (CR & PR). These findings suggested that combined arterial infusion chemotherapy of FAP may be feasible and a promising modality for the advanced HCC with intrahepatic metastases and/or portal vein thrombosis.
