False Negativity of Targeted Axillary Dissection in Breast Cancer [PDF]

Breast Care, 2021
<b><i>Introduction:</i></b> Targeted axillary dissection (TAD) has been proposed as an alternative method for the staging of patients with node-positive breast cancer who undergo neoadjuvant chemotherapy. However, not much is known yet about the false-negative rate (FNR) of the method and the subsequent risk of underestimation ...
