    Abstract:
    OBJECTIVE: We have reported that radiofrequency (RF) ablation with balloon occlusion of the hepatic artery (balloon-occluded RF ablation) increases the coagulation area compared with standard RF ablation. In this study, we evaluated the efficacy and safety of combination therapy with transcatheter arterial infusion chemotherapy (TAI) using iodized oil and balloon-occluded RF ablation in patients with hepatocellular carcinoma. PATIENTS AND METHODS: We studied 12 patients with 12 HCC nodules (mean tumor diameter, 27.3 mm). All patients were classified as Child-Pugh Class A. Immediately after TAI using iodized oil, we performed balloon-occluded RF ablation. RESULTS: One treatment session of the combination therapy was done for 10 of 12 nodules (83%). The greatest long-axis and short-axis dimensions of the area coagulated after the combination therapy were 48.8+/- 5.5 mm and 41.9 +/- 4.1 mm, respectively. During follow-up (mean, 33.4 months), there was no local recurrence. The 1, 2, and 3-year survival rates were 100%, 92%, and 83%, respectively. No fatal complications were observed. CONCLUSIONS: The combination therapy is an effective and safe treatment under favorable liver reserve capacity. Using the combination therapy, it is possible to finish one treatment session for patients with HCC nodules measuring less than 3 cm in greatest dimension.
