ORLANDO, FL (UroToday.com) - Stern and colleagues report on their experience with tissue biopsy more than 1 year after radiofrequency ablation (RFA) of small renal masses. The study included 19 patients with 20 renal masses (17 pre-treatment proven RCC and 3 oncocytomas) that had previously undergone RFA ablation, were stable in size on follow-up, and showed no evidence of enhancement on imaging. These lesions were percutaneously biopsied at a mean follow-up of 26.9 (13.1 - 58.0) months. Pathological evaluation, using H&E staining, revealed coagulation necrosis, hyalinization, immune cell infiltration, residual ghost cells, and no evidence of residual viable tumor.

Previous studies reported preserved tumor architecture for several months following RFA; therefore, current findings with longer-term follow up are significant. The biology of tumor-kill following RFA ablation is not clear-cut and deserves research efforts.

Presented by Joshua Stern, MD, Jay D. Raman, MD, and Jeffrey Cadeddu, MD, at the Annual Meeting of the American Urological Association (AUA) - May 17 - 22, 2008. Orange County Convention Center - Orlando, Florida, USA.
