title: The oncoplastic reduction approach to breast conservation therapy: benefits for margin control.
abstract: BACKGROUND
  Reduction mammaplasty during lumpectomy allows more generous resection and minimizes potential for poor cosmesis as compared with breast conservation therapy alone.
  
  
  OBJECTIVE
  The authors assessed the benefits of oncoplastic reduction for margin status in patients with breast cancer by conducting a retrospective review of cases of tumor resection alone vs tumor resection with oncoplastic reduction.
  
  
  METHODS
  Patients with breast cancer who underwent lumpectomy performed by a single oncologic surgeon between 2009 and 2013 were included. Patients were stratified into 2 groups based on surgical procedure: tumor resection with oncoplastic reduction (group 1) vs tumor resection alone (group 2). Patient demographics including risk factors, diagnosis, cancer stage, and procedure type were recorded. Tumor size, specimen weight, width of narrowest margin, and receptor status were determined. Outcome variables included margin positivity (≤1 mm), need for re-excision, and conversion to completion mastectomy.
  
  
  RESULTS
  A total of 222 breasts from 207 patients were included in the study: 83 in group 1 and 139 in group 2. The patients in group 1 had a lower incidence of positive margins and wider free surgical margins, required re-excision less often, and went on to completion mastectomy less often. Patients in group 1 were younger and had cancer that was more advanced. When controlling for these variables on multivariate regression analysis, the oncoplastic technique was independently associated with fewer positive margins and fewer instances of re-excision.
  
  
  CONCLUSIONS
  The oncoplastic reduction technique achieves wider free margins and less often necessitates re-excision or subsequent mastectomy. The long-term oncologic effect of this approach deserves further study.
