Focal Prostate Cryotherapy – Summary
Thomas J. Polascik, MD, FACS, Professor of Surgery at Duke University and Director of Surgical Technology at the Duke Prostate and Urological Cancer Center, discusses focal prostate cryotherapy and recent data on the treatment’s outcomes. He begins by describing the ideal patient for focal cryotherapy as someone with a greater than ten-year life expectancy and single or multiple mpMRI-visible, biopsy-proven Gleason Grade 2 prostate cancer (PCa) in locations amenable to ablation. Dr. Polascik outlines the procedure and states that the goals of the treatment are eradication of PCa, avoiding urinary and sexual dysfunction, and being a fast and simple outpatient procedure. He then begins discussing data on focal cryotherapy that shows that vitamin D3 functions as a sensitizer to cryoablation and that it is reasonable to re-treat about 20% of PCa patients with focal therapy. Dr. Polascik reviews the latest cryotherapy outcomes that all show focal cryotherapy to be approaching 100% rates of metastasis-free survival, cancer-specific survival, and urinary continence. He summarizes several studies that also show continence to be at about 95-100%, while potency was shown to be between 40-80%. Dr. Polascik then considers a study of long-term outcomes of focal therapy for low-intermediate risk cancer that found focal cryotherapy capable of increasing the time until radical or systemic therapy. He summarizes another study on anterior gland focal cryoablation showing that it can be effective based on erectile function and International Prostate Symptom Score (IPSS) not changing post-treatment. Dr. Polascik discusses expert consensus on how to surveil focal cryotherapy patients post-op, focusing on how in-field failure is a sign of poor treatment while out-of-field failure signals poor patient selection. He concludes by giving an overview of the Focal Therapy Society and by considering the future of focal cryotherapy.
