Cost-utility of Focal HIFU vs Prostatectomy

Standard treatment option of intermediate risk (ISUP2) prostate cancer (PC) is either radical prostatectomy (RP) or radiation therapy (RT). An attractive option for selected patients and for the health care system would be to spare the preserved gland to decrease urinary, sexual and digestive side effects of whole-gland treatments keeping with a good cancer control. For these reasons, focal treatments have been developed in localized PC. The principal objective of the EMERHIT study is to estimate, from the health system point of view, the efficiency (cost/utility study) of focal HIFU (F-HIFU) for intermediate risk PC compared to RP (either by open, laparoscopic or robotic surgical approach) at 24 months. It will be a multicentric pragmatic clinical trial, comparative, with no insu, randomized in two parallel groups : * (1) F-HIFU treatment * (2) RP Randomization will be equal (ratio 1:1), stratified on the centers and performed maximum at 2 months before the procedure. The comparison to the SNDS data will use the NIR of the patients selected for the study. The use of the SNDS data will allow, on top of the estimation of the care cost, to increase the patient's follow-up (with no supplemental visit) and measure, at 48 months, costs, mortality rate and cancer control measures From version 4.0 of the protocol, randomisation will be adjusted to a 2:1 ratio and stratified by centre.
