15064 Background: Radio-frequency ablation (RFA) and microwave coagulation therapy (MCT) have been developed as a useful locoregional treatment for hepatocellular carcinoma (HCC). It is still unclear which ablation therapy is superior for the patients with HCC, from the viewpoint of not only short term but also long term outcome. Methods: Between January 1991 and December 2005, 430 patients with HCC were treated with ablation therapy (230 RFA and 200 MCT) in our institution. Enroll criteria of this therapy were as follows; 1) unresectable HCCs, 2) each smaller than 3 cm, 3) up to three nodules, 4) without vascular invasion. Either percutaneous (P), endoscopic (E) or open (O) approach was selected individually based on location, size, number, or other factors. Treatment was repeated until complete ablation of HCC. Results: 1. Proportion of Child B or C was 62% and 60%; Stage III or IV was 56% and 58% in the patients with RFA and MCT, respectively. 2. Average tumor size and tumor number was 27mm/2.5 and 26mm/1.9 in the two groups. 3. Approaches were P: 55%, E: 33%, O: 12% in RFA and P: 48%, E: 30%, O: 22% in MCT. 4. Number of treatment was 1.1 in RFA and 1.2 in MCT. 5. Recurrence rate at the therapeutic site was 8% in RFA and 12% in MCT. Especially, endoscopic RFA provided a quite low recurrence rate (3%). 6. Cumulative 5-year survival was 52% versus 45% in the two groups. 7. Complication rate was significantly lower in RFA (5%) compared to MCT (11%). Intraabdominal tumor seeding (1% in MCT) and liver abscess formation (4% in MCT) was never encountered in RFA. Conclusions: Radio-frequency ablation for hepatocellular carcinoma is a safer procedure and can provide a similar favorable long- term prognosis compared to microwave coagulation therapy. No significant financial relationships to disclose.
