Population-based comparative effectiveness of salvage radical prostatectomy vs cryotherapy - Abstract

OBJECTIVE: To characterize population-based practice patterns, disease-specific and overall mortality, and cost associated with salvage cryotherapy (SCT) vs salvage radical prostatectomy (SRP).

METHODS: We retrospectively identified 440 men who failed primary radiation therapy and subsequently underwent SCT (n = 341, 77.5%) or SRP (n = 99, 22.5%) between 1992 and 2009 from Surveillance, Epidemiology, and End Results-Medicare linked data. Propensity score analyses were used to compare overall and prostate cancer-specific mortality and associated Medicare expenditures for SRP vs SCT.

RESULTS: Men undergoing SCT were more likely to be white (P < .001), less likely to be high school graduates (P = .008), and experienced shorter median time from diagnosis to salvage therapy (44.1 vs 60.1, P < .001) and from primary radiotherapy to salvage therapy (38.7 vs 55.8 months, P < .001). In adjusted analyses, overall mortality was higher (21.6 vs 6.1 deaths/100 person years, P < .001) for SRP vs SCT. There was a trend for higher prostate cancer-specific death rates with SRP vs SCT (6.5 vs 1.4 deaths/100 person years, P = .061). Medicare expenditures for SRP vs SCT were more than 2-fold higher ($19,543 vs $8,088, P < .001).

CONCLUSION: SRP vs SCT is associated with higher overall mortality and greater health care expenditures. However, longer follow-up is needed to assess long-term functional outcomes and cancer control.
