Surgery is the mainstay of treatment, but less than 20%-30% of patients are good candidates. Actually, thermal ablation is considered the best treatment with curative intent for cirrhotic patients with unresectable HCC≤ 3 cm. Unfortunately, radio frequency efficacy in obtaining the complete ablation of HCC nodules diminishes with increasing tumor size and local tumor progression is more frequent in larger nodules. To overcome these problems, higher-powered generators, different devices and techniques have been attempted. Furthermore, microwave ablation has been introduced with the promise of a large ablative capacity. The aim of this review is to describe the role of thermal ablation for the treatment of large unresectable HCC.展开更多
