Preservation of the nipple-areola complex in skin-sparing mastectomy for early breast cancer.

PURPOSE

Skin-sparing mastectomy (SSM) enables a radical cure of breast cancer while overcoming the cosmetic issues related to surgery. We review our experience of performing SSMs and assess whether preservation of the nipple-areola complex (NAC) could have been an option for some patients who underwent SSM.

METHODS

The subjects of this retrospective study were women who underwent SSM that utilized four incision types; namely, the so-called tennis racket incision, a periareolar and midaxillary incision, an areola-sparing and midaxillary incision, and a small transverse elliptical incision. We assessed whether preservation of the NAC would have been an option in SSM, based on histologic examination of three serial cut surfaces of the specimen around the nipple, ruling out the option when evidence of the malignant lesion/s was found in at least one of the following locations: in the nipple, within a 1-cm radius from the base of the nipple, or within 1 cm from the surface of the NAC.

RESULTS

We performed 193 SSMs. The cumulative 10-year local disease-free survival rate was 98%, with 89% of patients reporting levels of satisfaction with the reconstructed breast, of excellent, very good, or good. We evaluated that 70 of the 193 procedures could have been performed as nipple-sparing mastectomy (NSM).

CONCLUSIONS

The outcomes of SSM in this series were excellent and NSM might have been an option for about one-third of the patients.
