Sentinel lymph node biopsy is used to determine the need for axillary node dissection. This technique incurs cost associated with radio\u2010isotope administration and use of the operating room. Accordingly, there is a need to preoperatively identify patients with nodal metastases who can proceed directly to axillary dissection. Axillary ultrasound has increasingly been used to determine nodal status prior to surgery. It has been shown to be a sensitive and specific modality in the detection of nodal metastases. When combined with fine\u2010needle aspiration, the specificity of this modality significantly increases. Here we present a current review of the usefulness of preoperative axillary ultrasound in early and locally advanced breast cancer patients with and without fine\u2010needle aspiration biopsy. Based on this review, we estimate the proportion of patients that can be spared a sentinel lymph node biopsy and the concomitant benefit of axillary ultrasound in terms of cost.<\/jats:p>","DOI":"10.1007\/s00268-011-1319-9","type":"journal-article","created":{"date-parts":[[2011,10,26]],"date-time":"2011-10-26T02:56:15Z","timestamp":1319597775000},"page":"46-54","source":"Crossref","is-referenced-by-count":79,"title":["Accuracy of Axillary Ultrasound in the Diagnosis of Nodal Metastasis in Invasive Breast Cancer: A Review"],"prefix":"10.1002","volume":"36","author":[{"given":"Jonathan","family":"Cools\u2010Lartigue","sequence":"first","affiliation":[{"name":"Department of Surgery McGill University Health Centre H3A 1A1 Montreal QC Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarkis","family":"Meterissian","sequence":"additional","affiliation":[{"name":"Department of Surgery McGill University Health Centre H3A 1A1 Montreal QC Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2011,10,27]]},"reference":[{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365\u20102354.2008.01061.x"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.05.0936"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1245\/ASO.2003.12.017"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s002689900227"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjsurg.2007.06.017"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/00001703\u2010200202000\u201000008"},{"key":"e_1_2_9_8_2","doi-asserted-by":"publisher","DOI":"10.1245\/s10434\u2010010\u20100919\u20101"},{"key":"e_1_2_9_9_2","doi-asserted-by":"publisher","DOI":"10.1080\/028418600750013014"},{"issue":"6","key":"e_1_2_9_10_2","first-page":"492","article-title":"Ultrasound in dermatology.
