P013. Magnetic seeds: an attractive localisation option for the management of axillary node positive breast cancer

Introduction: There are 2 indications for accurate removal of a previously identified, involved lymph node: 1) after neoadjuvant chemotherapy (NACT) to ensure that the index node is assessed (targeted axillary dissection), and 2) for women with 1 or 2 abnormal nodes on imaging who may be eligible for sentinel node biopsy (SLNB) as per POSNOC. Dual localisation has an unacceptable false negative rate in the former and marking of the index node is advised. Although a node can be marked prior to NACT, finding that node poses a challenge.
