Postmastectomy irradiation was associated with a high rate of surgical complications and implant loss among patients who underwent IBR. Determining the number of positive SLNs prior to definitive resection and reconstructive operations may reduce complications and implant loss by guiding surgical decision making. Patients with a negative SLN are unlikely to require PMRT. Those with positive SLN(s) are high-risk IBR candidates with a quantifiable PMRT risk.

Breast cancer stem/progenitor cell populations differ in tumor-initiating potential but are not solely responsible for metastasis. Cancer stem/progenitor cells are less polyploid than cancer cells in general and may not be HER2/neu amplified. In normal breast tissue, breast stem/progenitor cell-like populations are present.
