The ablated tumor is non-enhancing (black).
The main disadvantage is time; the ablation can take anywhere from 2-3 hours. In comparison, radiation therapy or surgery may take less time depending on the operator. However, in contrast to surgery, patients do not have to undergo general anesthesia. Also, in contrast to radiation oncology, MR guidance allows for avoidance of neurovascular bundles and other sensitive sensitive surrounding structures.
The trial was for safety purpose only and has completed as of today. We do not yet know the oncologic outcomes. The study enrolled patients who were low to intermediate risk only based on targeted biopsy data and PSA.
The collected data will be analyzed to help refine the current approach, so stay tuned!
