The percentage of malignant prostate tumors detected very early is constantly increasing and the number of well differentiated tumors, with small volume and low risk of progression increases. When a tumor of this type is identified, radical prostatectomy remains the reference treatment, but this treatment is not without side effects. Active surveillance is a strategy which aims at detecting an early development of the cancerous disease in order to propose curative treatment in a timely manner and thus improve specific survival. Patients are therefore re-evaluated each year by rectal examination, PSA (Prostate-Specific Antigen) assay. Active surveillance remains difficult to manage psychologically for both the patient and the practitioner, because of the lack of treatment on the one hand and a rate of non-curable cancers close to 50% when signs of progression trigger a radical treatment. The aim of the focal treatment HIFU (High Intensity Focused Ultrasound) is to destroy the cancer without causing side effects in contrast to radical treatments. It is in this sense that it is positioned both as an alternative to radical surgery and as an alternative to active surveillance.

Eligibility | Inclusion Criteria: - Patient having been clearly informed of the study and having accepted, with sufficient reflection time, to participate by signing the informed consent form of the study. - Age between 50 and 80 years with a life expectancy of more than 5 years. Patients between the ages of 75 and 80 will need to have G8 score > 14. - Initial diagnosis of localized prostate cancer (T1c or T2a) with the following characteristics: - Only one Target tumor on MRI on a maximum of 2 contigous sextants.

Exclusion Criteria: - Contraindications to treatment with HIFU-F: - Tumor not accessible. - Multiple intra prostatic calcifications inducing, on ultrasound, a shadow cone in the prostate preventing the penetration of ultrasound and thus the realization of the treatment. - History of pelvic irradiation - Presence of an implant (stent, catheter) located less than 1 cm from the treatment area. - Fistula of the urinary tract or rectum. - Anal or rectal fibrosis, anal or rectal stenosis or other abnormalities making it difficult to insert the Focal One® probe. - Anatomical abnormality of the rectum or rectal mucosa. - Patient with artificial sphincter, penile prosthesis or intra prostatic implant, eg stent. - History of intestinal inflammatory pathology. - Uro-genital infection in progress (the infection to be treated before HIFU treatment). - Anterior surgery at the level of the anus or rectum making the introduction of the probe impossible. - Allergy to latex. - Thickness of the rectal wall> 10mm. - TURP indication. Bladder neck incision is allowed . - Patient with a medical contraindication to Sonovue® injection. - Patient with a medical contraindication on MRI. - Patient already treated for prostate cancer (hormone therapy, radiotherapy, surgery). - History of uncontrolled cancer and / or treated for less than 5 years (with the exception of basal cell skin cancer). - History of sclerosis of the bladder neck or urethral stenosis. - Patient with a several bleeding risk according to medical advice (patient with oral anticoagulant therapy must receive an alternative therapy if randomized in HIFU-F arm). - Patients with unstable neurological pathology. - Patient who has been treated for a therapeutic trial within 30 days of enrollment or who wishes to participate in an ongoing study that may interfere with this study. - Legal person protected by law. - Patient not able to understand the objectives of the study or refusing to comply with postoperative instructions. |

Primary | patient proportion who needed to seek radical treatment | The primary endpoint is the comparison between the 2 groups of the proportion of patient converting to a radical treatment at 48 months of follow-up. Conversion to a radical treatment is define as a medical decision based on the following criteria: An increase in Gleason score to a score 7 (3 + 4) with bilateral involvement (Gleason 6 or 7). An increase in the Gleason score to a score 7 (3 + 4) with tumor whose location is not compatible with a focal treatment (impossibility to apply safety margins of 9mm). An increase in Gleason score to a score of 7 (4 + 3) or higher. Risk of lymph node invasion> 5% (calculated with the MSKCC nomogram) An extension of the tumor beyond the prostatic capsule (MRI and / or biopsies). Appearance of pelvic ganglion metastases. |

Secondary | proportion of patients needing additional treatment | The objective is to compare between the 2 groups the proportion of patients needing additional treatment (focal or radical) at 24 months. This includes patients who wish or require radical treatment (prostatectomy, radiotherapy), total focal treatment, focal treatment for patients in the active surveillance group or additional treatment for patients in the treatment group. | 24 months | |
