PurposeTo evaluate outcomes of lymph node sampling in patients with suspicious axillary nodes without a diagnosis of breast cancer.Materials and methodsWe retrospectively identified all axillary ultrasound-guided sampling performed at our institution from 2003 to 2016 in patients.without malignancy.ResultsSeventy-eight lymph nodes met inclusion criteria. Two of the 78 sampled nodes (2.6%) were malignant.ConclusionSampling of suspicious nodes in patients without a history of breast cancer rarely yields malignancy. The malignancy rate approaches the 2% BIRADS 3 threshold. Further data may demonstrate that short-interval imaging follow-up is a safe alternative to sampling in this cohort.
