In the current study, 7538 men with localized disease were analyzed. Prostate cancer risk was assessed using the Kattan preoperative nomogram and the Cancer of the Prostate Risk Assessment (CAPRA) score, both well validated instruments that are calculated from clinical data at the time of diagnosis. A parametric survival model was constructed to compare outcomes across treatments adjusting for risk and age.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS:<\/jats:title><jats:p>In total, 266 men died of prostate cancer during follow\u2010up. Adjusting for age and risk, the hazard ratio for cancer\u2010specific mortality relative to prostatectomy was 2.21 (95% confidence interval [CI], 1.50\u20103.24) for radiation therapy and 3.22 (95% CI, 2.16\u20104.81) for androgen deprivation. Absolute differences between prostatectomy and radiation therapy were small for men at low risk but increased substantially for men at intermediate and high risk. These results were robust to a variety of different analytic techniques, including competing risks regression analysis, adjustment by CAPRA score rather than Kattan score, and examination of overall survival as the endpoint.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS:<\/jats:title><jats:p>Prostatectomy for localized prostate cancer was associated with a significant and substantial reduction in mortality relative to radiation therapy and androgen\u2010deprivation monotherapy. Although this was not a randomized study, given the multiple adjustments and sensitivity analyses, it is unlikely that unmeasured confounding would account for the large observed differences in survival.
