Background: Surgical resection is the treatment of choice for hepatic tumors; however, for various reasons, the vast majority of patients are not operative candidates. As a result, several local ablative therapies have emerged as alternatives to resection or as adjuncts in total oncologic care. Presently, the most widely employed liver-directed treatment is radiofrequency thermal ablation.
Methods: To define the current status of radiofrequency ablation (RFA), the authors reviewed available safety and efficacy data from select studies on RFA. A MEDLINE search was performed using the keywords "tumor type" + "radiofrequency ablation" + "survival." Only those studies containing long-term survival data on greater than 50 patients were included in this analysis.
Conclusions: Although RFA has been readily adopted into treatment paradigms, more rigorous trials are needed to solidify its place in the armamentarium of therapeutic strategies for hepatic malignancy.
