Clinical Series of Oncoplastic Mastopexy to Optimize Cosmesis of Large-Volume Resections for Breast Conservation

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.
