Which patients with early breast cancer need axillary clearance?

The role of axillary surgery in the management of early breast cancer is currently the topic of intense debate in the literature. There are strong indications that women are presenting with earlier tumours and hence the majority have negative axillary nodes making axillary dissection less beneficial both in terms of disease control and less likely to result in an alteration of management. Alternative less morbid axillary staging and non-axillary staging methods are being investigated, but sentinel node biopsy shows the most promise for reliable assessment of the axilla. This review aims to assess the current literature regarding the role of axillary surgery in breast cancer management. The reasoning why axillary dissection is still the gold standard in breast cancer management is explained and related to the other methods of axillary assessment and therapy. Suggested guidelines for current optimal management are made.
