METHODS: Inclusion criteria were unilateral PCa on biopsies (>5mm ISUP 1 or any ISUP 2-3), PSA level of ≤20 ng/ml and age 0.2 ng/ml. After treatment, all patients were followed by regular PSA measurements. All patients in FA group underwent MRI and systematic biopsies at one year. In addition, control MRI and prostate biopsy were done during the second post-treatment year in patients with PSA rising beyond the nadir +2 ng/ml. RESULTS: A total of 213 patients were enrolled, 107 were randomized to either FA and 106 to RP. After being randomized to RP, 26 patients (25%) refused RP and required FA. Six other patients declined treatment after randomization. There were no significant differences in mean age (64 vs. 66 years, p=0.3), PSA levels (8.6 vs. 8.5 ng/ml, p=0.9), MRI-measured index tumor diameter (14.5 vs. 15.5 mm, p=0.2), and prostate volume (41.3 vs. 41.7 ml, p=0.9) between FA and RP group at baseline. All included patients were evaluated respecting ITT rules. The proportion of treatment failure was 6.5% (7/107; 95% CI: 3 to 13) in the FA group and 7.5% (8/106, 95% CI: 4 to 14) in the RP group, resulting in a difference of 1% (95% CI: - 6.3 to 8.4). CONCLUSIONS: After a two-year follow-up, the rate of treatment failure in the FA group was found to be non-inferior to that in the RP group.
