WINSTON-SALEM, N.C. – A relatively new, minimally invasive treatment was 100 percent successful in eradicating small malignant kidney tumors in a study of more than 100 patients, report researchers from Wake Forest University Baptist Medical Center.The patients underwent CT-guided radiofrequency ablation (RFA) at Wake Forest Baptist for kidney tumors ranging in size from 0.6 cm to 8.8 cm. A total of 125 tumors in 104 patients were treated over the period 2000 to 2006. In all of the patients, a biopsy had confirmed the presence of renal cell carcinomas (RCC), a common type of renal malignancy.
