Detection of micrometastasis in the sentinel lymph nodes in breast cancer.

Background: The axillary lymph node (ALN) status is still the most important prognostic factor in the staging and treatment of breast cancer. Intraoperative lymphatic mapping and sentinel lymphadenectomy techniques were investigated in patients with early-stage breast cancer who did not have clinically palpable ALNs.

Methods: Forty-four patients with breast cancer underwent a sentinel lymph node biopsy (SLNB), followed by a complete axillary lymphadenectomy.
