EDAP TMS SA announced a recent presentation of positive results from a large, multicenter, non-inferiority study comparing Focal One high intensity focused ultrasound (HIFU) versus radical prostatectomy (RP) at the 38th Annual Congress of the European Association of Urology (EAU), which was held March 10-13, in Milan, Italy. The study, which ran from April 2015 through September 2019, compared Focal One HIFU versus RP as a first line treatment for patients with localized prostate cancer (grade groups <3). A total of 3,328 patients from 42 treatment centers were included: 1,967 were treated with Focal One HIFU and 1,361 underwent radical prostatectomy surgery.

Patients were followed for 30 months. Select data highlights: At 30 months, the STFS was higher in the HIFU arm (90.1%) compared with RP arm (86.8%); Risk of salvage treatment was greater than 1.2-fold higher after RP (HR: 0.75, 95% CI [0.64-0.96], p?=?0.02); ICS score, a measure of urinary incontinence, was significantly lower after HIFU (0 vs 1, p?0.0001); After HIFU, median PSA nadir was 0.34 ng/ml and positive biopsy rate was 12.5%; after RP, median PSA was 0.01 ng/ml and positive margins (PM) were reported in 26% of RP-treated patients.
