Long-Term Results of Optimized Focal Therapy for Prostate Cancer
Doctor GARY ONIK
Gary M. Onik, MD, while still in radiology residency training in 1982, at the University of California – San Francisco, described a brand new cancer treatment concept – a radiological procedure based on the possibility of image-guided thermal tumor ablation (destruction). His new procedure demonstrated a brand new approach and novel techniques for destroying a tumor through freezing or heating and then leaving it in place to be removed by the body rather than by surgery.
At the same time as his work on hepatic cancer ablation, Dr. Onik. developed the instrumentation and techniques that allowed for the cryosurgical ablation of prostate cancer, which is now an accepted alternative to radiation and radical prostatectomy and the preferred treatment for patients with radiation-recurrent prostate cancer. His concept of “focal therapy” for prostate cancer, treating only the prostate tumor rather than the whole gland, similar to a breast lumpectomy, is now a major research and treatment initiative in all of the major prostate cancer centers in the world.
