Abstrakt:	Simple Summary: Axillary management in breast cancer has undergone significant changes over the past decades, especially with the introduction of neoadjuvant chemotherapy (NACT). NACT aims to shrink tumors before surgery, allowing for less invasive axillary approaches such as sentinel lymph node biopsy (SLNB) and targeted axillary dissection (TAD). These techniques help reduce the need for axillary lymph node dissection (ALND), which is associated with higher risks of complications like lymphedema. However, patient selection for these procedures depends on factors such as tumor biology, response to NACT, and the extent of nodal disease. This review discusses the latest evidence supporting de-escalation strategies in axillary surgery and highlights ongoing research that aims to further refine the selection criteria for these approaches. Multidisciplinary collaboration remains key to implementing personalized treatments that optimize patient outcomes while minimizing surgical morbidity. Background. In breast cancer (BC) patients, axillary management has undergone major improvements over the last few years, and efforts to identify the optimal strategy for the management of axillary surgery are still ongoing. Methods. In current clinical practice, women with clinically node-positive (cN+) BC usually receive neoadjuvant chemotherapy (NACT) with the aim of reducing the extent of primary disease and, thus, allowing for axillary-conservative surgery. Remarkably, after NACT, up to one out of three patients achieves an axillary pathologic complete response, which, in turn, is associated with a more favorable prognosis than residual axillary disease. However, NACT is not without drawbacks, as NACT-associated inflammation can damage lymphatic vessels. Furthermore, varying degrees of response may occur in the axillary lymph nodes, increasing the false negative rate for sentinel biopsy. Results. At present, there is no consensus on the optimal approach in patients with cN+ BC undergoing NACT, although multidisciplinary management seems to be recommended. Conclusions. This narrative review provides a comprehensive overview of axillary management in cN+ BC patients undergoing NACT. It uses a multidisciplinary approach that encompasses the oncological management perspectives, as well as surgical and chemotherapeutic viewpoints. [ABSTRACT FROM AUTHOR]
