To the Editor:

We are grateful to Drs. Wenxiang Zhang, Xiangyu Wang, Yi Fang, and Jing Wang for carefully reading our manuscript “Margins in Breast-Conserving Surgery after Neoadjuvant Therapy.” They have identified an error in the following statement from the Results section: “Local recurrence occurred in 3 of 103 (2.9%) patients with 1.1- to 2-mm margins, 11 of 174 (6.3%) patients with > 2-mm margins, and 1 of 105 (1.0%) patients with a breast pCR.”

Because our primary analysis compared patients with ≤ 2-mm margins, > 2-mm margins, and breast pCR, this sentence should have stated: “Local recurrence occurred in 3 of 103 (2.9%) patients with ≤ 2-mm margins, 11 of 174 (6.3%) patients with > 2-mm margins, and 1 of 105 (1.0%) patients with a breast pCR.” As the readers describe, while unfortunate, this error does not change the results of our primary analysis nor the conclusions of the manuscript.
