Mastectomy May Be an Inferior Oncologic Approach Compared With Breast Preservation

To the Editor: In our recent publication in this journal we suggested that it may be important to parameterize the residual breast tissue (RBT) in patients undergoing various forms of mastectomy.1 We identified RBT in 66% and 83%, respectively, of therapeutic and prophylactic nipple-sparing mastectomies (Tables 1 and 2). Because of the characteristics of our sample, we were unable to formally analyze the relationship between these findings and oncologic outcomes, even though most of our patients had not received postoperative radiation therapy.
