Oncological outcomes of selective axillary dissection with 4% carbon marking.

Introduction: The use of axillary marking prior to Neoadjuvant Systemic Therapy (NST) is a controversial matter regarding patients with positive Lymph Nodes (LN). Several methods were tested to make possible the decrease of false negative rate in comparison to sentinel lymph node adding more accuracy to the results. This study aims to evaluate the oncological outcomes in patients who had undergone selective axillary dissection with 4% carbon marking before TSN.
