5. Study Description
Brief Summary
Conventional treatment options for localized prostate cancer include prostatectomy, radiotherapy and active surveillance. However, prostatectomy and radiotherapy carry certain degree of morbidity, including the risks of urinary incontinence, erectile dysfunction and injury to the structures in the proximity. Active surveillance carries the risk of disease progression and psychological distress to the patients. Focal therapy employs the concept of only destroying the significant lesion, resulting in disease cure and improved functional outcome. Among the different options of focal therapy, high-intensity focused ultrasound (HIFU) is one of the most commonly employed energy sources. It exerts its effect through thermal and mechanical destruction of cancer tissue. This study aims at assess the effectiveness of such treatment in prostate cancer management.
In this study, investigators evaluate the early oncological outcome and objective functional outcome of patients undergoing HIFU for the treatment of localized intermediate risk prostate cancer.
