RESUMO
BACKGROUND: The American Society of Breast Surgeons (ASBrS) Nipple Sparing Mastectomy Registry (NSMR) is a prospective, non-randomized, IRB approved, multi-institutional registry. The purpose of this Registry is to provide a large, prospective, non-randomized database of patient characteristics, tumor characteristics, surgical technique, and outcome (both aesthetic and oncologic) of the nipple sparing mastectomy (NSM). METHODS: Data is entered into the ASBrS NSMR, housed within the Mastery of Surgery Program, after patients consent to participation. Each investigator routinely offers NSM in their practice has obtained IRB approval and completed forms of agreement to participate in the ASBrS NSMR. RESULTS: This data set represents a total of 1,935 NSMs performed on 1,170 patients by 98 investigators from 70 institutions/sites. Of the 1,935 NSMs: 833 were performed for an indication of cancer [594 invasive carcinoma and 239 for ductal carcinoma in situ (DCIS)] and 1,102 were prophylactic. Of the 1,170 total patients, 352 underwent a unilateral and 818 underwent a bilateral NSM. Recurrence at a mean follow-up of 31 months/median follow-up of 27 months, with a range of 9.7 to 58.3 months since surgery was 1.4% with no recurrences at the nipple or nipple areola complex (NAC). Cancer occurrence (0.3%) also did not involve the nipple/NAC. Overall patient satisfaction of excellent/good: 94.9% and overall cosmesis (surgeon rated) of excellent/good was 96.4%. Overall infection rates included flap infection of 4.4%, NAC complication rate of 4.5% (defined as necrosis/other or ischemia/epidermolysis requiring surgery), and a 10% rate of NAC epidermolysis with full recovery. CONCLUSIONS: NSMs were performed on breasts with a variety of sizes and degrees of ptosis, via multiple incisions, dissection and reconstruction techniques with low complication rates and high patient satisfaction and surgeon rated cosmesis.
RESUMO
PURPOSE: To develop an atlas for oncoplastic surgery (OPS) with template dissection techniques via anatomically ideal incisions for breast conservation surgery. The evolution of breast conservation techniques has evolved from placing an incision directly over the lesion to the incorporation of a thoughtful decision making process utilizing oncoplastic surgical (OPS) techniques to combining OPS with incision placement in anatomically advantageous sites. The high survival rates of breast cancer and effect of breast surgery on quality of life reinforce emphasis of optimal oncologic as well as aesthetic outcome. OPS results in greater patient satisfaction, fewer surgeries, and is oncologically safe. Today's breast surgeon is tasked with optimizing both oncologic and aesthetic outcomes. METHODS: Presentation of reproducible dissection techniques and incision placement strategies to afford surgeons a step-by-step approach of OPS via anatomically ideal incisions in breast conservation surgery. RESULTS: Demonstration of reproducible techniques to facilitate the decision making process of optimal breast conservation surgery, eliminate knowledge gaps for surgeons, optimize outcome for individuals undergoing breast conservation surgery, and decrease disparity of care. CONCLUSION: Adoption of OPS techniques utilizing an anatomically ideal incision in breast conservation surgery is a feasible and reproducible practice for breast surgeons. Application of these techniques results in maintained optimal shape, size, and contour without the typical overlying skin envelope scars. OPS techniques performed under the skin envelope result in expected OPS oncologic and aesthetic outcomes with the addition of the resulting scar(s) in anatomically discrete position(s).
