- How to Read a Study Record
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.

Experimental: HIFU treatment
65 patients will receive the immediate treatment with focal HIFU in order to destroy the cancer without causing side effects. HIFU treatment will be conducted with the Focal One® device. The treatment area will be defined using MRI data and 3D biopsies. A safety distance of at least 9 mm will be defined around the tumor. An intraoperative contrast echocardiographic control will be performed to evaluate the necrotic area. If necessary, additional HIFU lesions will be performed during the same session. In case of residual tumor demonstrated during control biopsies, additional treatment of this tumor with focal HIFU may be proposed. Patients randomized in this arm will also have PSA dosage, MRI exam, questionnaires and prostatic biopsies during their follow up. |
Procedure: treatment with focal HIFU
HIFU treatment will be conducted with the Focal One® device. The treatment area will be defined using MRI data and 3D biopsies. A safety distance of at least 9 mm will be defined around the tumor. An intraoperative contrast echocardiographic control will be performed to evaluate the necrotic area. If necessary, additional HIFU lesions will be performed during the same session. In case of residual tumor demonstrated during control biopsies, additional treatment of this tumor with focal HIFU may be proposed. Biological: PSA dosage PSA dosage will be regularly performed during patient follow up thanks to blood sampling. Device: MRI MRI exam will be regularly performed during patient follow up. Other: Questionnaires Patients will have to complete five questionnaires during their follow up : QLQ-C30 (Quality of Life questionnaire), EPIC-26 (The Expanded Prostate Cancer Index Composite), IPSS (International Prostate Score Symptom), IIEF-5 (The International Index of Erectile Function), STAI-YB (State-Trait Anxiety Inventory) Procedure: Prostatic biopsies Prostatic biopsies will be regularly performed during patient follow up. |
Active Comparator: Active surveillance
65 patients will be randomized to active surveillance and will have exactly the same follow-up as treated patients excepting the HIFU treatment. Active surveillance is a therapeutic option that shifts the eventual moment of curative treatment while remaining within a window of curability of the disease. Patients randomized in this arm will also have PSA dosage, MRI exam, questionnaires and prostatic biopsies during their follow up. |

- 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.
