Outcomes of immediate breast reconstruction in patients undergoing single-stage sentinel lymph node biopsy and mastectomy.

The ability to more definitively plan breast reconstruction after obtaining final histologic analysis of the sentinel lymph node biopsy (SLNB) has led several groups to advocate a staged approach to SLNB and mastectomy. Certain disadvantages are inherent in that approach, including increased patient morbidity, financial expense, and inconvenience. A retrospective review was conducted 195 procedures in which mastectomy and SLNB were performed in a single stage with immediate breast reconstruction (IBR) over a 10-year period. Long-term outcomes were analyzed within the context of patient characteristics and SLNB results. Intraoperative SLNB analysis was found to be a reliable method for planning IBR, as there were no patients noted to have untoward sequelae as a result of a false-negative SLNB, and the probability of postmastectomy radiation therapy was predictable based on the intraoperative SLNB results. We advocate that SLNB be performed in a single stage with mastectomy and IBR.
