The nipple-sparing mastectomy: early results of a feasibility study of a new application of perioperative radiotherapy (ELIOT) in the treatment of breast cancer when mastectomy is indicated.
BACKGROUND
Breast cancer surgery has become less and less mutilating, however a mastectomy is required in the case of multicentric, large tumors or recurrences after conservative treatment. The removal of the nipple areola complex during the mastectomy dramatically increases the feeling of mutilation. To reduce this negative psychological impact, in cancers located outside of the central area of the breast, we propose a new type of nipple-sparing mastectomy associated with intraoperative electron beam radiotherapy (ELIOT) delivered on the region of the areola. The nipple-sparing mastectomy is performed leaving 5 mm of glandular tissue behind the nipple areola complex to preserve its blood supply. The reconstruction is immediately performed with a prosthesis or an autologous flap.


METHODS
Twenty-five patients were included in the study; two of them had a bilateral nipple-sparing mastectomy.


RESULTS
Pathological examinations demonstrated the presence of 19 infiltrating carcinomas and 8 ductal carcinoma in situ. Two patients had a superficial skin areolar slough followed by spontaneous healing. One necrosis of the areola occurred due to extensive retroareolar dissection. In the early follow-up, the color of the areola was preserved. All patients except one expressed their satisfaction of having kept their areola.


CONCLUSIONS
These preliminary results are encouraging but they require further studies to evaluate the long-term results, the local recurrence rate and the psychological impact.
