Focal Ultrasound Prostate Ablation Shows Promising Results with Fewer Side Effects
A procedure that eliminates only the diseased part of the prostate in prostate cancer patients has shown promising results while causing fewer side effects, including incontinence and impotence, compared to traditional surgery and radiation therapy. The approach is known as high-intensity focal ultrasound (HIFU). Findings from the first U.S. group study of focal therapy were presented during the Southeastern Section of the American Urological Association in a poster titled, “Functional and Oncologic Outcomes of High Intensity Focused Ultrasound (HIFU) for Focal Treatment of Prostate Cancer: A single Institution Experience.” The study, conducted at the University of Miami's Miller School of Medicine, enrolled 50 prostate cancer patients with a median age of 68, who underwent partial ablation of the prostate gland using EDAP TMS' HIFU system, called Ablatherm Robotic HIFU. Because the process only ablates the diseased part of the prostate, healthy tissue is preserved, minimizing side effects. Following the procedure, patients had prostate-specific antigen (PSA) tests every three months, and magnetic resonance imaging–fusion biopsy at six or 12 months, depending on whether they were high- or low-to-intermediate-risk patients, respectively. Median PSA levels before treatment were 5.5 ng/mL. Three months after HIFU, however, most patients' levels (83%) had dropped to below 2 ng/mL. Among the 18 patients who u
