Physician Information: RFA MethodRadiofrequency ablation is the most widely used method of percutaneous tumor ablation. It has been predominantly used to destroy tumors of the liver, with good results. Current research indicates that RFA treatment of small primary tumors of the liver is as effective as surgical resection. Physician Information: Other Forms of Tumor AblationWhile RFA uses heat to destroy tumors, cryoablation uses freezing temperatures to the same end. It has been less studied than RFA, but the method is showing promise in treating tumors that may not be ideal candidates for heat treatment. Physician Information: RFA OverviewPercutaneous tumor ablation is a minimally invasive method of destroying tumors. Physician Information: Safety and Side EffectsBecause RFA and other tumor ablation methods are minimally invasive, they carry a much lower rate of complications than surgical procedures. Complications occur in 1% to 4% of cases. Physician Information: RFA in PracticeRFA is not a new technology; the method has been used for decades to treat benign bone tumors and cardiac arrhythmia. RFA devices are currently FDA-approved to treat liver tumors that are not eligible for surgery, painful bone tumors, and other soft-tissue tumors. Physican Information: Tumor Ablative Therapies ExplainedAt its most basic, tumor ablation is a method of destroying a tumor without major surgery. A needle electrode guided to and inserted inside the tumor produces either extreme heat or extreme cold, which destroys the tumor from the inside out. Physician Information: Frequently Asked QuestionsTumor ablation therapies are a method of targeting and destroying a tumor from the inside out. The most common type of tumor ablation is radiofrequency ablation (RFA). |
