Abstract
We report the first documented clinical case of the use of magnetic seeds to mark axillary lymph node metastasis in breast cancer before neoadjuvant chemotherapy. After chemotherapy, the patient showed a complete radiological response. One single sentinel lymph node was detected using a radiotracer, while the marked node was intraoperative magnetometer-guided identified. The analysis of the nodes showed negative sentinel lymph node and positive marked node, and the subsequent targeted axillary dissection was performed. Marking axillary positive lymph nodes with a magnetic seed is a simple and effective procedure for the intraoperative localisation of the node after neoadjuvant treatment.
