“…Axillary sentinel lymph node biopsy (SLNB) has become the key means of minimally invasive assessment of axillary lymph nodes (ALNs) status in EBC patients (3), which can reduce complications such as affected side upper limb edema and paresthesia caused by ALN dissection (ALND). In patients with negative ALNs after NAT, if more than three SLNs are removed intraoperatively, or if a marked lymph node is included in the removed SLNs, the intraoperative false negative rate (FNR) of SLNBs can be reduced to 7-10% (4,5).…”
