Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to provide prospective evidence that the use of Magseed/Sentimag in marking axillary lymph nodes and guiding surgical localization in patients with breast cancer following neo-adjuvant chemotherapy (NAC) is effective.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a post-market, prospective, open-label, single arm study of Magseed and Sentimag in patients with breast cancer with biopsy-proven axillary node metastases who had a clip placed to mark the metastatic node and are having that clipped node selectively removed at surgery following neo-adjuvant chemotherapy (NAC). Subjects will have the Magseed placed to mark axillary lymph nodes with biopsy-proven metastasis under ultrasound guidance before initiating NAC. After completion of NAC, the Magseed will be localized using the Sentimag system during surgery and removed with the targeted lymph node.
