The status of the axillary lymph nodes (AX) is widely accepted as the most significant prognostic factor in breast cancer.

However, their value as prognostic indicators remains undetermined. Whether these factors are independent prognostic factors, or merely related to other variables, such as AX metastasis, is unclear. A clear need for a new biologic markers to serve as more reliable prognostic factors exists.
