Axillary Staging of Early-Stage Invasive Breast Cancer by Ultrasound-Guided Fine-Needle Aspiration Cytology: Which Ultrasound Criteria for Classifying Abnormal Lymph Nodes Should Be Adopted in the Post-ACOSOG Z0011 Trial Era?

Conclusions—
Cortical thickness of greater than 3.5 mm in the most suspicious nodes is appropriately predictive of patients with 3 or more tumor-involved axillary nodes. When this criterion for US-guided FNAC was adopted, a group of patients with 1 or 2 metastatic nodes could be spared unnecessary 1-step axillary lymph node dissection.
