This trial is testing a new treatment called the TULSA Thermal Therapy System—a device that uses focused ultrasound waves guided by MRI imaging to heat and destroy prostate cancer tumors. The goal is to treat small, slow-growing cancers more precisely, destroying only the cancer itself while preserving healthy prostate tissue and avoiding the urinary and sexual side effects that come with traditional surgery or radiation therapy.
Many men with small, low-grade prostate cancers face a difficult choice: undergo major surgery or radiation that can cause permanent incontinence and erectile dysfunction, or do nothing and watch their cancer. This treatment aims to fill that gap by offering a gentler option that targets the tumor directly without harming the rest of the prostate.
If you qualify, you will undergo the TULSA Thermal Therapy System procedure, which uses focused ultrasound waves guided by real-time MRI imaging to carefully heat and destroy the targeted cancer tissue. The procedure is performed while you are under anesthesia. You will also be enrolled in a companion study that tracks your cancer and tissue samples over time to monitor how well the treatment works and whether you experience any side effects.
