Indication for skin-sparing mastectomy with or without nipple preservation for primary breast cancer.

Skin-sparing mastectomy (SSM) is one of the available operation methods for breast cancer. We discuss here indications for SSM for primary breast cancer. We carried out SSM for 28 patients with breast cancer. Their clinical features were compared with those in patients who underwent breast-conserving treatment (BCT). Fifteen of the 28 patients received SSM according to schedule. The remaining 13 patients who were scheduled to undergo BCT received SSM because of involvement of the surgical margin. Clinical features indicating suitability for SSM included extensive intraductal cancer growth and multicentricity. The length of intraductal cancer growth in these patients was significantly greater than that in 24 patients who received BCT (2.28 versus 0.571 cm; P = 0.000078). Tumor size and tumor-nipple distance were not indicating factors for this treatment. SSM, which is advantageous in terms of aesthetic outcome and oncologic safety, may be widely indicated after careful evaluation by magnetic resonance imaging or pathologic examination.
