Surgical treatment of the axilla in patients with breast cancer has changed with the arrival of the neoadjuvant systemic therapies (NST); the role of axillary lymph node dissection with the use of radiotracers, fluorescent particles, surgical clips and radioactive seeds appears to play a significant role following these systemic therapies. We present a novel dual technique (^99mTc-Nanocoll^® or ^99mTc-Lymphoseek^®) for sentinel lymph node biopsy (SLNB) and the use of magnetic seed (Magseed^®) for the achievement of more accurate and less invasive method to restaging the axilla after NST.
