173 Background: Nipple-sparing mastectomy (NSM) is being performed more frequently for risk reduction and breast cancer treatment. Prior whole breast irradiation (WBI) has been considered a contraindication to NSM. This study reviews our NSM experience following prior WBI. Methods: We reviewed our prospective mastectomy database from April 2007 to April 2012 for patients undergoing NSM. Ten patients out of a total 169 NSM were identified that underwent NSM following prior WBI. Data collected included incision type, follow-up, complications, cosmesis, and recurrence. Results: Of the ten NSM patients who received prior WBI, 6 had recurrent ipsilateral breast cancer at the lumpectomy site, 3 developed contralateral breast cancers and opted for bilateral NSM, and 1 patient opted for bilateral NSM after finding a BRCA mutation following BCT. Mean patient age was 53. Two patients had comorbities: 1 hyperlipidemia and 1 former smoker. Three of 10 (30%) developed complications, with 2 partial necrosis of nipple-areola complex (NAC) and 1 complete loss of the NAC (Table). No patient required return to the operating room (local resection in the office was performed for the complete NAC loss) and all patients had good final cosmesis. All patients underwent immediate reconstruction: 5 tissue expanders (TE), 2 DIEP and 3 TRAM flaps. Mean follow up is 23 months with no local recurrences to date. Conclusions: This study demonstrates that NSM with immediate reconstruction can be performed in selected patients with prior WBI with an acceptable rate of nipple preservation and good cosmesis. NAC preservation is the ultimate goal in patients undergoing NSM. Current studies are ongoing to identify risk factors that may be associated with nipple necrosis. [Table: see text]
