Combination therapy with transcatheter arterial infusion chemotherapy using miriplatin and percutaneous radiofrequency ablation for hepatocellular carcinoma

Abstract

Miriplatin is a platinum complex developed to treat hepatocellular carcinoma (HCC) via administration into the hepatic artery as a sustained-release suspension in iodized oil. We retrospectively evaluated the efficacy of combination therapy with transcatheter arterial infusion chemotherapy using miriplatin and percutaneous radiofrequency ablation for HCC in 11 patients. Immediately after transcatheter arterial infusion chemotherapy using miriplatin, we performed radiofrequency ablation. The greatest long-axis and short-axis dimensions of the area coagulated after combination therapy were 42 mm (35-80 mm) and 34 mm (32-60 mm), respectively. During follow-up (median 12 months), there was no recurrence from the same subsegment. No serious adverse events were observed. These results suggested that using the combination therapy, it is possible to finish one treatment session for patient with HCC.
