Feasibility Study of Ablathermy Focused Ultrasound (USF) of Breast Tumors Before Mastectomy

Not Applicable
Terminated
Conditions
Breast Tumor
Interventions
Procedure: ablathermy focused ultrasound
Registration Number
NCT01827969
Lead Sponsor
Institut Bergonié
Brief Summary

The treatment consists of tumor ablation by Ablathermy Focused Ultrasound (USF), guided by MRI, performed under local anesthesia and sedation.

Detailed Description

The treatment consists of tumor ablation by USF, guided by MRI, performed under local anesthesia and sedation. Patients will be operated (mastectomy) from 48 hours after ablation.

Primary Outcome Measures
NameTimeMethod
Evaluate the effectiveness of ablathermy2 years

Evaluate the effectiveness of ablathermy focused ultrasound breast tumors on histological criteria in terms of destruction of the tumor mass by coagulation necrosis

Secondary Outcome Measures
NameTimeMethod
- Assessment of apoptotic phenomena in the margins of lesions treated2 years

* Assessment of apoptotic phenomena in the margins of lesions treated

* Know the immediate complications focused ultrasound

* Assess the pain experienced by patients during the procedure performed under sedation.

* Check the real-time processing by mapping temperature measured by MRI and correlate these mappings to the histological findings
