BACKGROUND/AIM Axillary reverse mapping (ARM) aims to identify and preserve arm drainage in order to prevent lymphedema following axillary lymph node dissection. Oncological-safety and feasibility are still debated, especially in patients with locally-advanced breast cancer (LABC). We report the first case of the AXMAP 1.0 study performed in our Institution. PATIENTS AND METHODS A 52-year-old patient with a triple-negative LABC and partial response to neoadjuvant chemotherapy underwent axillary lymph-node dissection using fluorescence ARM. RESULTS Two lymph-nodes draining the ipsilateral upper arm were identified and were not preserved due to suspicion of malignancy. Pathological examination confirmed the presence of malignancy in both lymph nodes. CONCLUSION Further studies should be designed in order to validate the oncological safety of this technique, especially in patients with LABC requiring neoadjuvant chemotherapy.
