Histopathological findings after radiofrequency (RITA) treatment for prostate cancer

Radiofrequency interstitial tumor ablation (RITA) is a thermal ablation method that uses needles and low radiofrequency (RF) energy. The aim of our study was to evaluate the histopathology of thermal lesions induced by RF energy delivered interstitially in prostate cancer patients who subsequently underwent prostatectomy, and to determine the feasibility, effectiveness and safety of this new method in a pilot study.
