Background: Ultrasound Guided Fine Needle Aspiration (US-FNA) is being increasingly used for staging the axilla preoperatively. Overall this approach identifies 30 - 40 % of patients with occult metastasis. However, Complete Axillary Dissections (CAD) after a (+) US-FNA in patients with minimal disease may be considered overly aggressive. This study focuses in the selection of patients that will benefit the most from this procedure.
Design: See Figure 1

Results: See Figure 2

Conclusions: To avoid overtreating the axilla, this study suggests: 1- That CAD should only be performed after a (+) US-FNA when the corresponding sonographic findings show strong evidence of N2-3 disease. 2- That patients with small (< 5mm) isolated, single node cortical abnormalities will not benefit from a US-FNA and 3 - That the extent of axillary surgery in patients with cortical abnormalities > 5mm in > 1 LN must be a limited one. In these patients either with a (+) US-FNA or a (+) SNB, the surgeon should be aware of the possible extent of disease and plan the dissection accordingly.
