Radio-frequency ablation of large, nonresectable hepatic tumors.

Patients with nonresectable hepatic metastases who are not treated survive an average of 6 months. We report our experience with radio-frequency ablation (RFA) of nonresectable hepatic tumors 4 cm or greater in size. A retrospective chart review of all patients undergoing RFA of hepatic tumors 4 cm or greater from October 1, 1999, through August 31, 2002, was performed.
