## Abstract
The accuracy of sentinel lymph node dissection (SLND) in clinically node-positive patients who receive neoadjuvant chemotherapy has been investigated in clinical trials. This survey was designed to assess familiarity and impact of these trial findings into practice.

American Society of Breast Surgeons members were invited by e-mail to complete an anonymous online survey. A total of 642 members responded (21% of 3090 eligible members). Results were summarized as proportions based on the number of responses to each question.

Respondents indicated knowledge of the Z1071 (86%), SENTINA (57%), and SN-FNAC (39%) trials. The published false negative rates (FNR) of the trials were correctly reported by 53% (336/638) of respondents. Before the trials, 45% (285/636) offered SLND compared with 85% (543/638) after the trials. In the 556 respondents who reported knowledge of at least one trial, 310 (56%) currently offer SLND to >50% of patients, 175 (31%) offer to <50%, and 70 (13%) routinely perform axillary lymph node dissection. Respondents who reported knowledge of the trials but did not change their practice to incorporate SLND (n = 67) cited concerns over lack of outcome data (64%), worries about FNR (42%), lack of resources (34%), or objections from radiation oncologists (25%), medical oncologists (18%), or other surgeons (8%).

The publication of trials evaluating SLND in clinically node-positive patients has resulted in changes in practice. Concerns over the FNR and lack of outcome data limit incorporation of SLND into practice by some surgeons.
