RESUMO
BACKGROUND: We evaluated oncologic outcomes and complications of skin-sparing mastectomy (SSM) and nipple-sparing mastectomy (NSM) with immediate reconstruction (IR) after neoadjuvant chemotherapy (NAC) in patients with early-stage and locally advanced breast cancer (BC). METHODS: BC patients from 2000 to 2014 treated with NAC followed by SSM/NSM and IR were reviewed. Patient demographics, tumor characteristics, NAC response, complications, and recurrence were analyzed. RESULTS: Two hundred sixty-nine patients with 280 BCs were treated with NAC followed by SSM (94%) or NSM (6%) with IR. Median age was 47 (26-72) years with a median follow-up of 45 months. Pathologic complete response (pCR) was noted in 49 (17.5%) cases. Overall 30-day complication rate was 13.2%. Variables associated with complications included BMI (P < 0.0001), tobacco use (P = 0.015), and adjuvant radiation (P = 0.025). Local-regional recurrence was 3.2% and metastatic recurrence was 13.2%. Variables predicting recurrence risk were pre-NAC tumor size (P < 0.001), residual tumor size (P = 0.002), Grade III (P = 0.002), HER-2 negative (P = 0.025), pre-NAC nodal disease (P = 0.05), and lack of pCR (P = 0.045). CONCLUSION: Following NAC, risk factors for complications in patients undergoing SSM/NSM with IR are high BMI, smoking, and adjuvant XRT. SSM/NSM following NAC is associated with excellent local control. These data support expanding the indications for NSM/SSM to include patients receiving NAC.

BACKGROUND: Inflammatory breast cancer (IBC) is an aggressive disease that is treated with trimodality therapy consisting of neoadjuvant chemotherapy, surgery, and post-mastectomy radiation therapy (PMRT). Traditionally, modified radical mastectomy without reconstruction has been the operation of choice for patients with IBC due to fears of high rates of margin positivity, risk of local recurrence, and the need for PMRT. METHODS: A retrospective review was performed to evaluate women with IBC at our institution from 2006 to 2014 who completed trimodality therapy. Patients were identified as undergoing reconstruction or no reconstruction (NR), with reconstruction being further classified as immediate (IR) if reconstruction occurred at the initial surgery, or delayed (DR) if initial reconstruction occurred after PMRT. RESULTS: Sixty women with IBC were identified using inclusion criteria. The median follow-up was 2.3 years (range 1.4-4.6). Patients with IR had a statistically significant increased risk (p = 0.006) in postoperative complication rates compared with DR (0 %) and NR (2.6 %). Two patients had positive skin margins on final pathology (one IR, one NR), with both eventually having recurrence. Time to PMRT was delayed 10 days in patients with IR compared with those without IR. No statistically significant difference in recurrence rates was observed (p = 0.86) when comparing patients with IR and those with NR, and no difference in survival was observed between patients who had reconstruction and those without (p = 0.91). CONCLUSION: Performing IR with mastectomy for IBC is associated with increased complications, but is not associated with decreased survival or increased recurrence in selected patients. IR in selected IBC patients can facilitate successful breast reconstruction.
