In advanced stage stomach cancer, the disease may spread (i.e., metastasize) to other parts of the body such as the liver. One tool doctors at Cancer Treatment Centers of America use to kill small, metastatic tumors in the liver is radiofrequency ablation.
With radiofrequency ablation, doctors use ultrasound guidance to place a thin, needle-like device into the center of a liver tumor. The tip of the device then emits electrical energy (i.e., radiofrequency waves), which heats and destroys the cancer cells.
Radiofrequency ablation is less invasive and less painful than traditional, open surgery. It can be applied through the skin or during a surgical procedure. It may be an appropriate treatment for stomach cancer patients who have multiple liver tumors, or who have been previously treated with surgery.
