In men with low-risk prostate cancer, European and American guidelines recommend either active surveillance or whole-gland treatments, with significant induced morbidity and burden on quality of life. Focal treatments of the index tumor are currently under investigation to decrease morbidity while proposing active treatment.~The purpose of this study is to determine the feasibility, precision and safety of a novel ablation treatment using microwaves, delivered transrectally under real-time guidance with MRI-transrectal ultrasound image registration. The index tumor will be detected with prostate MRI and characterized with targeted biopsies using MRI-transrectal ultrasound image registration. It will then be ablated with microwaves using the same transrectal approach and guidance system (KOELIS).
The purpose of this study is to determine if trans-rectal microwave ablation of the index tumor of patients with low-risk prostate cancer is sufficiently precise and safe, using MRI-transrectal ultrasound image registration.
