RFA is a technology that safely heats of “cooks” tumors using radiofrequency induced temperature changes. RFA produces heat-generated coagulation of targeted tissues resulting in tumor necrosis of tumor “death.” The procedure is performed under CT scan and Ultrasound guidance. Through a tiny nick in the skin in the right lower chest, a probe is placed directly into the liver tumor. Once in the proper position, the wires are deployed and the interstitial heating process begins. Heating is applied for about 10 minutes. The probe is withdrawn and the procedure is over. Subsequent CT scans are performed a few times a year to monitor results and for possible new growth. This technique is currently applied to monitor results and for possible new growth. This technique is currently applied to the liver only and is performed on patients who are otherwise poor surgical candidates or who do not wish to undergo major abdominal surgery. Patients with primary liver cancers as well as cancer that spread to the liver (metastasis) are considered candidates. The procedure’s major strength includes its minimally invasive approach without requiring open surgery. Like surgery, however, it is potentially curative.
