MRI- Guided Transurethral Ultrasound Ablation of Localized Prostate Cancer

Not Applicable

Completed

• Conditions: Localized Prostate Cancer; Ablation Therapy; MRI Guided Transurethral Ultrasound Ablation
• Interventions: Procedure: Magnetic Resonance Imaging-Guided Transurethral Ultrasound Ablation of Prostate Tissue

• Registration Number: NCT03996005
• Lead Sponsor: University Hospital, Strasbourg, France

Brief Summary

Primary purpose :

Evaluation of the efficiency and safety of an alternative global prostate treatment in localized prostate cancer.

Primary Objective:

Absence of clinically significant cancer (CSC) on control biopsy at 1-year follow-up.

Secondary Objectives:

1. Biochemical response

2. Presence of any CSC on biopsy at 1- and 2-year follow-up

3. Radical treatment free survival

4. Adverse events, clinical tolerance

5. Urinary continence

6. Erectile function

7. Quality of life
