Thermal Ablation is the destruction of cancer by extreme heat or freezing. The most common technique uses radio waves (microwaves) to generate heat. This technique is called radiofrequency ablation (RFA). The destruction of cancer by freezing is known as cryoablation.
Radiofrequency Ablation is a minimally invasive procedure in which a hollow needle is placed directly into the tumor. The physician guides the placement of this needle using image guidance, such as Computed Tomography or Ultrasound. Once the needle is properly placed, metal tines are deployed from the hollow core of the needle. These tines penetrate and envelope the tumor.
When the tines are in place, radio waves are transmitted to the needle tip and though the tines. These radiowaves generate heat which "cooks" the tumor. This technique can be used to treat lung, liver, bone, kidney, adrenal and breast cancers, including patients with metastatic disease. RFA is especially appropriate for patients who cannot tolerate surgery.
Radiofrequency ablation is not the same as radiation therapy. Radiofrequency ablation uses low-frequency radio waves, which generate localized heat, not the destructive radiation given off by radioactive elements.
Radiofrequency ablation can be used to target some large tumors by repositioning of the needle. Because of its versatility, RFA has become a treatment option for a growing number of cancer patients.
