Abstract
We conducted a prospective randomized trial to evaluate the efficacy of Lipiodol in intrahepatic arterial infusion chemotherapy for patients with hepatocellular carcinoma (HCC). A total of 38 patients with unresectable HCCs and underlying cirrhosis were entered in this trial, and 36 of them were evaluable. Every 4 weeks, 17 patients received 70 mg of 4′-epidoxorubicin (epirubicin) alone (group A), whereas 19 patients received a Lipiodol emulsion containing the same dose of epirubicin (group B) through the hepatic artery. A tumor response (CR+PR) was observed in 12% of group A patients and in 42% of group B patients. The group B patients showed a significantly higher response rate than the group A patients. There was a tendency for an increased duration of survival (P=0.09) in the group B patients. These results suggested that the infusion of the Lipiodol emulsion with epirubicin was more effective than epirubicin alone for the treatment of these patients with HCC.
