The AMAROS trial showed no difference in outcomes between axillary lymph node dissection (ALND) and axillary radiation in women with cT1-2N0 breast cancer with positive sentinel lymph nodes (+SLNs). Axillary management in men remains unstandardized, so we assessed current trends and outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Males with cT1-2N0M0 breast cancer undergoing mastectomy with one to two +SLNs were identified from the National Cancer Database (2018\u20132021).

Patients with two +SLNs more often underwent ALND+PMRT (43% vs. 19%,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.001). The use of PMRT rose over time (23\u201336%), whereas ALND alone declined (27\u201312%). Additional positive nodes were found in 31% of ALND cases, with no difference between ALND and ALND+PMRT.
