OBJECTIVES: To report the 10-year oncologic and functional outcomes of whole-gland HIFU as first-line treatment for localized prostate cancer (PCa).
PATIENTS AND METHODS: Patients were retrospectively included between January 2005 and July 2018 from a prospectively maintained database at a single academic institution. No patient underwent androgen deprivation therapy prior to HIFU. Primary endpoint was biochemical recurrence-free survival (BRFS). Secondary oncological endpoints included salvage treatment-free survival (STFS), cancer-specific survival (CSS) and overall survival (OS).
RESULTS: A total of 97 patients met our inclusion criteria and were included in the final analysis. According to D'Amico classification, the numbers of patients with low-, intermediate-, and high-risk disease were 38 (39.2%), 52 (53.6%), and 7 (7.2%). A total of 21 (21.6%) patients received salvage treatment at a mean of 4.1 years (± 2.8) after HIFU. The 10-year OS, CSS and BRFS rates were 91.8%, 100% and 40.3% in the overall cohort, respectively. In multivariate analysis, predictive factors for biochemical recurrence were intermediate-risk group (RR = 2.065; 95% CI 1.008-4.230; p = 0.047) and PSA nadir > 0.5 ng/mL (RR = 4.963; 95% CI 2.251-10.947; p < 0.001). Symptoms related to bladder outlet obstruction were the most frequently recorded adverse events. In multivariate analysis, positive biopsy on the prostatic apex was predictor of obstructive complications (RR = 3.2, 95% CI 1.092-9.476, p = 0.034). Only four patients developed severe urinary incontinence (> 1 pad/day).
CONCLUSIONS: HIFU showed low PCa-specific mortality, but biochemical recurrence rates were highly variable among patients. Future studies are needed to improve patient selection.
