简要总结
Focal treatment of localized prostate cancer aims to destroy the cancerous foci without damaging surrounding tissues to avoid the side effects of radical treatments. This is why focal treatment is positioned as an alternative to radical surgery as well as an alternative to active surveillance.
This study is a feasibility study. It aims at treating the index tumor (the most aggressive one) which determines the vital prognosis of patient, while preserving the maximum surrounding prostatic tissue to preserve quality of life. The expected result is the total destruction of aggressive tumor areas by focal or multifocal treatment strategy using the Focal One® device (EDAP-TMS, Vaulx-en-Velin, France). The tumor destruction is validated by the negative biopsy rate between 6 and 12 months post-treatment.

- •OR Gleason score of 6 AND corresponding focal lesion on MRI with a PIRADS (Prostate Imaging Reporting and Data System) score ≥4/5 and a diameter ≥5 mm,
- •OR Gleason score of 7 (3+4) whatever the biopsy invasion length or the MRI results may be.
- •Patient with normal anal and rectal anatomy.
- •Patient with a condition corresponding to an ASA (American Society of Anesthesiologists) classification 1 or
- •Patient for which treatment by focal HIFU (without performing an associated TURP) has been validated in Multidisciplinary meeting.
- •Accepting patient monitoring constraints defined in the context of the study.
- •Patient affiliated to health insurance or beneficiary a similar plan.
