BACKGROUND: We have reported that magnetic resonance axillography (MR-axillography) is the best method for assessing lymph node size and representing the relation of the lymph node to normal anatomy.
METHODS: The four largest nodes on MR-axillography were sampled in 62 consecutive patients with breast cancer undergoing axillary clearance. Axillary clearance yielded a mean of 17.0 (range 5-28) nodes.
RESULTS: A method of preliminary sampling of four nodes in the axilla oriented by MR-axillography was assessed in all cases, 22 of whom were histologically node positive. Based on the sampled nodes, lymph node metastases were detected in 20 of 22 (91%) of the node-positive patients. Based on the sampled nodes, of the 19 patients with macrometastatic nodes, lymph node metastases were detected in all 19 (100%), but only in 1 of the 3 (33%) patients with only one micrometastatic node.
CONCLUSIONS: This experience indicates that sampling the four largest nodes by MR-axillography orientation accurately identifies patients with macrometaststic nodes. This result may be comparable to that of surgical sampling performed by the most skilled surgeons.
