Abstract

|
We present our initial experience of ultrasound (US)-guided localization of clipped metastatic axillary lymph nodes (LNs) following neoadjuvant chemotherapy (NAC). We evaluated US visibility and the successful excision rate of clipped LN after NAC in 29 consecutive patients with breast cancer. US-guided localization of clipped nodes was performed in 22 patients on the day of surgery, while seven patients underwent surgery without localization. The clips were identified in all patients with residual metastatic LNs and 6 of 12 (50%) patients without residual metastatic LNs on US. Six patients without visible clips underwent US-guided localization at the presumed previous clip insertion site. The successful excision rate of 22 LNs with localization was 100% (even though 3 of them were non-sentinel LNs) and 57% (4/7) without localization. Regardless of the presence of visible residual metastatic LNs on US after NAC, successful excision of the clipped LN with US-guided localization is feasible.
