BACKGROUND: Radiofrequency ablation has recently become a viable treatment option for unresectable primary or secondary lesions confined to the liver. OBJECTIVE: To study the local therapeutic efficacy, side effects and complications of radiofrequency ablation for the treatment of @entity157 and liver @entity3 . This is the first reported experience of radiofrequency ablation for treating malignant @entity99 in Israel. METHODS: Fifteen consecutive @entity1 , aged 53-73 years, with 23 lesions (8 @entity1 with @entity157 and 7 with secondary @entity96 ) underwent radiofrequency ablation under general anesthesia. RITA nine-array 5 cm thermal ablation catheter and the model 1500 generator were used. The mean diameter of all @entity5 was 4.28 cm (range 1-10 cm). Three lesions were 1-3 cm in diameter (small), 17 lesions measured 3.1-5 cm (medium), and 3 measured 5.1-10 cm (large). RESULTS: Complete @entity39 was found in 8 (66%) of 12 HCCs by computed tomography scan. Of the remainder, diffuse @entity5 recurrence was demonstrated in three lesions (25%) after @entity4831 injection and there was one local @entity5 recurrence. In the @entity3 group complete @entity39 was found in 5 of 11 lesions (45%). One major complication ( @entity298 ) was treated with antibiotics and four (26%) minor complications (right @entity1143 , small subcapsular @entity1410 ) were monitored. CONCLUSIONS: Radiofrequency ablation appears to be an effective, safe and relatively simple procedure for the treatment of @entity96 .
