How Much of the Axilla Should Be Dissected?
The spread of breast cancer from the primary tumor in the breast to regional lymph nodes is an indication of the capacity of cancer cells to implant and grow, as well as a comment on the host-tumor relationship; it also is a potential source of morbidity. Despite the clear impact of axillary nodal metastases on prognosis, there is no evidence that axillary treatments significantly affect survival. Al- though the possibility of a small therapeutic benefit cannot be excluded by the studies to date, the primary benefits of removing axillary lymph nodes are to gather information on Staging and to prevent complications arising from uncontrolled tumor growth in the axilla. Information on axillary Staging is vital when the axillary node status is a major determinant of the use of systemic therapy.
