In answer to Postop's request from Tudpuck to provide radiation studies that show superior results to surgery:
EFFECTIVENESS OF BRACHYTHERAPY
The following are published studies supporting the effectiveness of Brachytherapy in achieving cure rates higher than or equal to surgery.

Cleveland Clinic, 11 years: 96% low; 84% intermediate; 71% high. “Brachy more successful than surgery in low risk cases”
MSK, 1819 patients, 5 year follow up; “Reoccurrence rates similar with surgery, Brachytherapy, and External beam.”
Journal of Urology, 173, 2005
12 year follow up: 1449 patients; 93% disease free survival. Biochemical reoccurrence:
89% low; 78% intermediate, 63% high.
Seattle Prostate Institute: 10 year follow up: metastic free survival 97%; local control 97%.
ICER, Dec, 2008: “Brachytherapy is the most cost effective method of treating prostate ca.”
The largest study was the just released Prostate Cancer Study Group Results which showed Brachy superior to surgery in all risk catagories.
Data from the Dattoli Cancer Center shows similar results.
All of these are retrospective studies, but the data comes from well respected organizations and are published and peer reviewed.
