Evaluation of Percutaneous Treatment by Cryoablation of Unifocal Invasive Breast Carcinoma in Menopausal Women With Indication of Lumpectomy
Evaluation of Percutaneous Treatment by Cryoablation of Unifocal Invasive Breast Carcinoma in Menopausal Women With Indication of Lumpectomy
The primary objective of this monocentric and feasibility study is to review the efficacy of
 cryotherapy in the treatment of unifocal mammary carcinomas in post-menopausal patients, with
 lumpectomy indication.

 The efficacy is defined by the rate of success of cryotherapy procedures. For each one of
 those evaluated process, an success will be defined on the tumor sample of lumpectomy by the
 absence of viable tumour cells.

 On the basis of our expertise, it seems interesting to propose this experimental procedure to
 patients as described above.
