ImportanceFocal therapy involves treating only the cancerous area within the prostate rather than the whole gland. Comparative effectiveness data for oncological and functional outcomes are lacking.
ObjectiveTo evaluate oncological and functional outcomes of focal therapy in comparison to radical prostatectomy in patients with clinically significant, non-metastatic prostate cancer.
DesignA 1:1 propensity score matched study, reviewing patients undergoing focal therapy or radical prostatectomy between November 2005-September 2018.
SettingProspective multicentre databases for focal therapy (high intensity focused ultrasound and cryotherapy) and radical prostatectomy were analysed for eligibility.
ParticipantsPatients with PSA<20ng/ml, Gleason=4+3 and stage=T2c that underwent radical prostatectomy or focal therapy were matched for treatment year, age, PSA, Gleason score, T-stage, maximum cancer core length and neoadjuvant androgen deprivation therapy use.
InterventionFocal therapy compared to radical prostatectomy.
Main outcome and measuresPrimary outcome was failure-free survival (FFS) defined by need for salvage whole-gland or systemic therapy or metastases. Secondary outcomes were all-cause mortality, erectile and urinary functional outcomes.
Results335/572 patients underwent radical prostatectomy, and 501/761 patients underwent focal therapy, high intensity focused ultrasound (n=626) and cryotherapy (n=135) were eligible for matching. After propensity score matching, 246 radical prostatectomy (mean [SD] age 63.4 [5.6] years, median [IQR]
