SentiMag® Intraoperative Comparison in Breast Cancer

This is a pivotal, prospective, open label, multicenter, paired comparison of the SentiMag® and SiennaXP® magnetic sentinel node localization system with the standard of care (radioisotope with blue dye) for lymph node localization in the detection of lymph nodes in patients with breast cancer undergoing a sentinel lymph node biopsy. The trial is designed to provide powered evidence that the lymph node detection rate of the SentiMag® and SiennaXP® system is non-inferior to the standard of care in patients with breast cancer.
