Oncoplastic surgery in the USA: a review of where we started, where we are today and where we are headed.

The surgical management of breast cancer has evolved tremendously over the last century and now includes oncoplastic techniques that improve both cosmetic and oncologic outcomes for patients. The purpose of this review is to provide the reader with a broad overview of the history of oncoplastic breast surgery in the United States (USA), and to summarize important patient factors and technical innovations for optimal operative planning in the era of multimodal treatment of breast cancer. The indications for oncoplastic surgery (OPS) have broadened significantly as more women pursue breast conservation with preservation of their native breast tissue. The operative philosophy of OPS is based on fundamental reconstructive principles, with technique selection based largely on tumor size and location. Reduction mammoplasty and mastopexy techniques have become some of the most utilized procedures in OPS due to their versatility to address tumors in almost all areas of the breast. Volume replacement techniques with locoregional perforator flaps continue to gain popularity as a single-stage reconstructive option for women with large tumor to breast ratios, especially with specialized plastic surgeons at high volume, academic centers. The oncologic advantages of OPS have allowed women to avoid mastectomy with improved margin control, re-excision rates, and equivalent overall survival all while preserving the aesthetic outcomes for these patients. Despite the proven benefits of OPS, numerous healthcare systems barriers including insurance status, geographic location, referral patterns, and racial disparities all continue to play a role in access to surgical sub-specialized breast oncology care demonstrating the need for ongoing research and education about oncoplastic principles.
