Clinical series of oncoplastic mastopexy to optimize cosmesis of large-volume resections for breast conservation.
BACKGROUND
Oncoplastic mastopexy has been popularized as a method to hide the cosmetic effects of central or large-volume resections associated with breast conservation surgery for breast cancer.


METHODS
This review was undertaken to study the uses and limitations of these techniques in providing adequate breast conservation lumpectomy for breast cancer of any stage in a single surgeon's practice. A review of breast cancer cases March 2004 through December 2009 were analyzed for the use of oncoplastic reconstruction in breast conservation surgery.


RESULTS
A total of 167 patients had lumpectomies during this period associated with oncoplastic mastopexy reconstruction. The average age was 55.6 years with a range of 33-85 years. Stage 0 breast cancer accounted for 33 cases (19.8%), and 134 cases were invasive cancers stages 1-3 (stage 1, 34.1%; stage 2, 30.6%; and stage 3, 15.6%). The most common oncoplastic techniques used were, in order of frequency: batwing mastopexy, parallelogram mastopexy, and Modified Wise pattern mastopexy. Positive or close margins (≤ 2 mm) were present in 37 of 167 cases (22%). Positive margins were most associated with higher stage, positive nodes, positive lymphovascular invasion (LVI), use of neoadjuvant chemotherapy, and larger initial T stage, positive estrogen receptor (ER), and younger age. Of these higher stage, node positive, and use of neoadjuvant chemotherapy were statistically significant in this small series (P values = 0.034, 0.016, and 0.022, respectively). Ki-67 and HER2 status were not associated with positive margins. Positive margins were manageable by local re-excision of a solitary face of the prior resection wall in more than 2/3 of cases to achieve negative pathologic margins. Only 11 of 167 required mastectomy because of failure to achieve adequate margins for oncologic control.


CONCLUSIONS
Oncoplastic mastopexy allows the surgeon to address large tumors or tumors in cosmetically difficult sites adequately for breast conservation. Careful margin marking and re-excision of close or positive margins is still often feasible to achieve adequate negative margin with acceptable cosmesis in spite of the large initial volumes of resection.
