Contemporary analysis of erectile, voiding, and oncologic outcomes following primary targeted cryoablation of the prostate for clinically localized prostate cancer

Abstract

Purpose: To evaluate erectile function (EF) and voiding function following primary targeted cryoablation of the prostate (TCAP) for clinically localized prostate cancer (CaP) in a contemporary cohort. Materials and Methods:We retrospectively reviewed all patients treated between 2/2000-5/2006 with primary TCAP. Variables included age, Gleason sum, pre-TCAP prostate specific antigen (PSA), prostate volume, clinical stage, pre-TCAP hormonal ablation, pre-TCAP EF and American Urologic Association Symptom Score (AUASS). EF was recorded as follows: 1 = potent; 2 = sufficient for intercourse; 3 = partial/insufficient; 4 = minimal/insufficient; 5 = none. Voiding function was analyzed by comparing pre/post-TCAP AUASS. Statistical analysis utilized SAS software with p < 0.05 considered significant. Results: After exclusions, 78 consecutive patients were analyzed with a mean age of 69.2 years and follow-up 39.8 months. Thirty-five (44.9%) men reported pre-TCAP EF level of 1-2. Post-TCAP, 9 of 35 (25.7%) regained EF of level 1-2 while 1 (2.9%) achieved level 3 EF. Median pre-TCAP AUASS was 8.75 versus 7.50 postoperatively (p = 0.39). Six patients (7.7%) experienced post-TCAP urinary incontinence. Lower pre-TCAP PSA (p = 0.008) and higher Gleason sum (p = 0.002) were associated with higher post-TCAP AUASS while prostate volume demonstrated a trend (p = 0.07). Post-TCAP EF and stable AUASS were not associated with increased disease-recurrence (p = 0.24 and p = 0.67, respectively). Conclusions: Stable voiding function was observed post-TCAP, with an overall incontinence rate of 7.7%. Further, though erectile dysfunction is common following TCAP, 25.7% of previously potent patients demonstrated erections suitable for intercourse. While long-term data is requisite, consideration should be made for prospective evaluation of penile rehabilitation following primary TCAP.

Focal therapy with high-intensity focused ultrasound for prostate cancer in the elderly: a feasibility study with 10 years follow-up

“…The ongoing evolution of imaging is also an exciting and important variable in the development of focal therapy (31). As previously defined for open radical prostatectomy, the trifecta remains the essential group of variables to evaluate for any focal therapy approach (1,32). At the beginning of the HIFU experience, we neither had a definition of risk of recurrence, nor a definition for focal therapy.…”
