INTRODUCTION: Ten-year disease-specific survival for clinically localized prostate cancer after radiation is 93%, 88%, and 80% for low-, medium-, and high-risk groups, respectively. The objective of this study was to report long-term cancer survival outcomes for patients who had undergone prostate cryotherapy at our institution more than 10 years ago. To date, this is the longest reported follow-up after cryotherapy. MATERIALS AND METHODS: A retrospective patient chart review, conducted of an Institutional Review Board (IRB)- approved cryotherapy database, identified 76 men who had undergone prostate cryotherapy before January 1999. Pre-, intra-, and posttreatment data were collected. Primary study endpoints were overall mortality and prostate-cancer-specific death. Secondary endpoints were disease recurrence and clinical progression. RESULTS: Mean patient age was 69.2 (47.4-86.3) years; median preoperative prostate-specific antigen was 5.3 (0.2-208.0); mean Gleason score was 7. Forty of 76 (52.6%) were confirmed D'Amico high risk. Median follow-up was 10.1 (0.2-14.9) years; 25 patients underwent primary treatment; 51 postradiation. After 10 years of follow-up, 43 of 76 men (56.6%) were still alive; 33 men (43.4%) had died-10 (13.2%) from prostate cancer, 18 (22.4%) from noncancerous causes, and 5 (6.6%) unknown. CONCLUSIONS: The long-term results of prostate cryotherapy in our series indicate an 87% overall 10-year prostate-cancer-specific survival, despite early cryotherapy technology and the majority of patients being D'Amico high risk.
