The new treatment relies on MRI guided transurethral ultrasound to focus heat directly on the cancer cells, while sparing the delicate non-cancerous tissues. Sunnybrook researchers Dr Michael Bronskill and Dr Rajiv Chopra have licensed their innovation and formed Profound Medical Inc., which will develop the technology for clinical use.
Unlike surgical removal of the prostate, the treatment is minimally invasive and could be performed without a lengthy hospital stay. In preclinical studies, treatment takes less than 30 minutes. The therapy, on which clinicians at Sunnybrook will conduct preliminary testing in preparation for a clinical trial, could help limit the number of men living with the common, debilitating and often permanent side effects of surgery and radiation treatments currently used. More of these invasive therapies are being performed now because improved awareness among younger men has converged with better clinical detection tools.
