Summary

A significant proportion of patients with localized prostate cancer, and treated for curative intent by radiotherapy, have a local recurrence. Among these patients with local recurrence, few receive curative remedial treatment but most of them are treated with palliative hormonal therapy without any chance of long-term recovery.

The use of Focused Ultrasound (HIFU) in focal treatment (only on recurrence) is an effective and not very morbid option, especially compared to surgery. The quality of this treatment is conditioned by both an early diagnosis of recurrence, a precise localization of recurrence in the prostate and a rigorous extension assessment for the detection of occult metastases.

Innovations in medical imaging have led to the development of a new generation of "hybrid" machines that combine PET (Positron Emission Tomodensitometry) and MRI (Magnetic Resonance Imaging) technology. Associated with the use of 68Gallium-labeled PSMA (Prostate-Specific Membrane Antigen), a new tracer specific for prostate cancer, the investigators believe that this PET-MRI imaging technique can:

1. To identify at an early stage the metastatic patients and to allow a more adapted therapeutic management.
2. A better evaluation of the limits of local recurrence and therefore a more precise definition than with MRI alone of the tumor zone to be destroyed.

Finally, the investigators believe that the PET-MRI / 68Ga-PSMA exam, used for the selection of patients eligible for focal HIFU treatment and used for the treatment itself, should allow obtaining an optimal control of the cancer recurrence with the least possible side effects.

PROCEDURE

Focal HIFU using PET-MRI/68Ga-PSMA imaging guidance

Focal HIFU treatment will be conducted with the Focal One® device using the PET-MRI/68Ga-PSMA imaging. The treatment area will be defined using PET-MRI/68Ga-PSMA imaging data and 3D biopsies.
