RFA safe for treating liver tumors pushing on GI tract; Alcohol injection makes RFA more effective
Radiofrequency ablation (RFA), the use of electrodes to heat and destroy abnormal tissue, is a safe and effective treatment for eradicating liver tumors that are in contact with the gastrointestinal (GI) tract, says one study in the November 2004 issue of the American Journal of Roentgenology, while a separate study in that same issue says that RFA becomes even more effective when alcohol is injected into a liver tumor before an RFA procedure.
