BackgroundNipple-sparing mastectomy is appropriate for selected patients with early-stage breast cancer or high breast cancer risk. However, the postoperative rate of nipple necrosis is relatively high (10 to 30 percent). This study analyzed the impact of clinicopathologic and surgical variables on partial and total nipple necrosis rates after nipple-sparing mastectomy and compared overall complication rates between nipple-sparing and skin-sparing mastectomy.MethodsThe study included 233 cases; 113 had nipple-sparing mastectomy and immediate breast reconstruction and 120 were matched cases of skin-sparing mastectomy and immediate reconstruction performed at the authors' institution from September of 2003 through May of 2011.ResultsThe overall complication rate was 28 percent for nipple-sparing mastectomy and 27 percent for skin-sparing mastectomy (p > 0.99). In patients who did not have axillary surgery (those undergoing risk-reducing mastectomy), the overall rate was significantly higher in the nipple-sparing group (26 percent versus 9 percent; p = 0.06). However, in patients who had axillary surgery (either sentinel lymph node biopsy or axillary lymphadenectomy), the rate did not differ between the two groups. For nipple-sparing mastectomy, the overall incidence of any (partial or total) nipple necrosis was 20 percent. Only two cases (2 percent) had total necrosis. Larger breasts (C cup or larger) were associated with a higher rate of nipple necrosis (p = 0.003).ConclusionsThe authors found no significant difference in the overall incidence of complications in patients who had nipple-sparing mastectomy or skin-sparing mastectomy. Exclusion of axillary lymphatic surgery in nipple-sparing mastectomy patients did not decrease the incidence of complications.
