Radiofrequency Ablation and Microwave Ablation for Liver Tumors

Chapter

Abstract

The development of image-guided percutaneous techniques for local tumor ablation has been one of the major advances in the treatment of liver malignancies. Among these methods, radiofrequency (RF) ablation is currently established as the primary ablative modality at most institutions. RF ablation is accepted as the best therapeutic choice for patients with early stage hepatocellular carcinoma (HCC) when liver transplantation or surgical resection is not a suitable option [1, 2]. In addition, RF ablation is considered a viable alternative to surgery in patients with limited hepatic metastatic disease, especially from colorectal cancer, in patients deemed ineligible for surgical resection, because of the extent and location of the disease or concurrent medical conditions [2]. Microwave (MW) ablation is a new, promising technique that seems to offer many of the advantages of RF ablation while possibly overcoming some of the limitations [3]. The following is a practical guide for performing image-guided thermal ablation of liver tumors.
