Background: This analysis was performed in order to determine whether primary tumor location in breast cancer affects the axillary sentinel lymph node (SLN) identification (ID) rate, the false negative (FN) rate, incidence of axillary nodal metastases, or the number of SLN identified. Methods: In this prospective multi-institutional study, SLN biopsy was performed on clinical stage T1-2, NO breast cancer patients using blue dye alone or in combination with radioactive colloid, followed by completion axillary LN dissection. Results: Central tumor location was associated with an improved FN rate, which may be related to reliable drainage from the subareolar lymphatic plexus. Tumor location did not significantly affect the SLN ID rate or the mean number of SLN identified. Medial tumor location was associated with a decreased rate of axillary nodal metastasis. Conclusions: Breast cancers drain reliably to the axillary lymph nodes regardless of tumor location within the breast. (C) 2001 Excerpta Medica, Inc. All rights reserved.
