From MD Anderson’s website on Dr. Curley...
Seven years ago, we began preclinical studies utilizing radiofrequency ablation for thermal destruction of hepatic malignancies. The preclinical studies led to clinical trials that began 5 years ago. Our group has now performed radiofrequency ablation in more than 450 patients with primary or metastatic hepatic malignancies, and we have defined the indications, limitations, and complications associated with this treatment. The results of our phase I and II clinical trials utilizing radiofrequency ablation led to successful United States Food and Drug Administration approval of radiofrequency ablation as a treatment in patients with hepatic malignancies.
Forgot to add this is getting ready to go to phase III clinical trials, could be very positive but far away from curing all types of cancer. This is my opinion only.
