Introduction:
Prostate cryotherapy is an available treatment option for localized prostate cancer (PC) included on minimal invasive therapies but still under evaluation. We started our cryotherapy program in 2008 for selected patients with localized PC. Our objective is to evaluate the oncologic and functional outcomes of primary cryotherapy in men with clinically localized PC.
Subjects And Methods:
We retrospectively evaluated all patients who underwent primary cryotherapy for localized PC treatment at our center between January 2008 and December 2017. In order to downsize prostates between 40 and 60cc neoadjuvant 3-month hormonal therapy was administered. Primary endpoint was biochemical progression-free survival (BPFS) rate as defined by the Phoenix criteria. Secondary endpoints were cancer-specific survival (CSS), overall survival (OS), patient reported functional outcomes and complication rates. Factors influencing de BPFS were evaluated individually using Kaplan-Meyer and Cox regression models and in a multivariate model using Cox regression.
Results:
During the mentioned period, a total of 177 men were treated with cryotherapy. With a mean follow-up of 60 months (SD 32.9), the Kaplan-Meier analysis shows an overall BPFS rate was 67%. BPFS by risk group was 70.2%, 70.3% and 50.0% for the low, intermediate and high risk groups, respectively (p = 0.925). Overall time to BR was 93.67 months (SD 2.84, IC95%: 88.10-99.24): 95.91 (SD 3,44), 93.23 (SD 4.81) and 89.77 (SD 6.67) months for the low, intermediate and high risk groups, respectively. In both univariate and multivariate analysis, the only predictor of biochemical progression was de PSA nadir (HR 1.56 IC95%: 1.50-1.63). Continence was fully maintained in 95% of patients after the procedure. Postoperative complications included UTI (17.5%), hematuria (9.6%), perineal hematoma (11%) and postoperative pain (4.5%). No fistulas were reported. 8.5% of patients had acute urinary retention solved conservatively.
Conclusion:
Cryotherapy is a safe option for selected patients with localized prostate cancer that provides competitive oncologic outcomes and a low morbidity profile.
