Axillary staging for breast cancer is vitally important for determining app
ropriate adjuvant hormone and chemotherapy. In the absence of distant metas
tases, axillary lymph node status remains the most accurate predictor of cl
inical outcome. Sentinel lymph node biopsy is a minimally invasive approach
with enhanced accuracy and less morbidity than conventional axillary disse
ction. The stage is now set for the sentinel lymphadenectomy staging to mov
e from state-of-the-art care to the standard care in coming years. (C) 2000
