Primary Cryotherapy for High-Grade Clinically Localized Prostate Cancer: Oncologic and Functional Outcomes from the COLD Registry.

Journal Article

OBJECTIVE: To evaluate the oncological and functional outcomes of primary cryotherapy in men with clinically localized, high-grade prostate cancer. SUBJECTS AND METHODS: We included all men with biopsy Gleason score ≥8, localized (cT1-2) disease with a serum prostate-specific antigen (PSA) ≤50 ng/mL from the Cryo On-Line Data (COLD) registry. The primary outcome was biochemical progression free survival (BPFS) as defined by the Phoenix criteria (nadir PSA +2 ng/mL). Secondary outcomes of continence (defined as strictly no leak) and potency (able to have intercourse) were patient reported. Factors influencing BPFS were evaluated individually using Kaplan Meier and in a multivariate model using Cox regression. RESULTS: Altogether, 300 men were included for analysis. The median follow-up was 18.2 months (mean 28.4) and median BPFS was 69.8 months. Based on Kaplan-Meier analysis, the estimated 2- and 5-year BPFS rate was 77.2% and 59.1%, respectively. Neoadjuvant hormonal therapy was administered to 41% of men and this tended to occur in men with larger prostates, likely as a technical consideration for downsizing before cryosurgery. At multivariate analysis, the presence of Gleason score 9 or 10 (Hazard Ratio [HR] 1.9) and a posttreatment PSA nadir of ≥0.4 ng/mL (HR 5.7) were the only significant variables associated with biochemical progression using Cox regression. Complete continence was noted in 90.5% of men and potency in 17% of men at the 12-month follow-up. The incidence of rectourethral fistulae and urinary retention requiring intervention beyond temporary catheterization was 1.3% and 3.3%, respectively. CONCLUSION: Primary cryotherapy appears to be effective and safe in the community setting for high-grade, clinically localized prostate cancer in the short term.
