Studies have shown that EBUS has a high positive predictive value; however, its negative predictive value (NPV) varies significantly. The aim of the current study was to evaluate the clinical outcome surrounding negative and nondiagnostic EBUS\u2010FNA of mediastinal LNs.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>A retrospective chart review of cases of EBUS\u2010FNA performed between 2008 and the middle of 2011 was conducted. Mediastinal LNs with cytologic diagnoses of negative for malignant cells and unsatisfactory were selected for the study. Each LN was followed for up to 1 year with imaging or biopsy\/surgical resection. A true\u2010negative result was defined as a LN that did not enlarge on repeat imaging or was negative for malignancy on repeat biopsy or surgery during the follow\u2010up period.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Among 1418 LNs sampled, 479 from 228 patients met the search criteria, including 394 LN (82.3%) with the cytologic diagnosis of negative for malignant cells and 85 (17.8%) with a diagnosis of unsatisfactory. A total of 104 patients (45.6%) were followed with imaging, and 124 patients (54.3%) underwent repeat biopsy\/surgery. A total of 445 LNs met the definition of a true\u2010negative finding, resulting in an overall NPV of 92.9% (95% confidence interval [95% CI], 90.6%\u201095.2%). The NPVs of a negative and unsatisfactory diagnosis were 93.9% (95% CI, 91.6%\u201096.3%) and 88.2% (95% CI, 81.4%\u201095.1%), respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>The vast majority of LNs with a cytologic diagnosis of negative and unsatisfactory were likely to be true\u2010negative findings. In these patients, a more conservative approach to follow\u2010up may be appropriate. <jats:bold><jats:italic>Cancer (Cancer Cytopathol)<\/jats:italic> 2015;123:92\u201397.<\/jats:bold> \u00a9 <jats:italic>2014 American Cancer Society<\/jats:italic>.<\/jats:p><\/jats:sec>","DOI":"10.1002\/cncy.21482","type":"journal-article","created":{"date-parts":[[2014,9,3]],"date-time":"2014-09-03T15:45:52Z","timestamp":1409759152000},"page":"92-97","source":"Crossref","is-referenced-by-count":15,"title":["Outcome of patients with negative and unsatisfactory cytologic specimens obtained by endobronchial ultrasound\u2010guided transbronchial fine\u2010needle aspiration of mediastinal lymph nodes"],"prefix":"10.1002","volume":"123","author":[{"given":"Hiren J.","family":"Mehta","sequence":"first","affiliation":[{"name":"Division of Pulmonary, Critical Care, and Sleep Medicine, Department of Medicine University of Florida College of Medicine Gainesville Florida"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nichole T.","family":"Tanner","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care, Department of Medicine Medical University of South Carolina Charleston South Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerard","family":"Silvestri","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care, Department of Medicine Medical University of South Carolina Charleston South Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suzanne M.","family":"Simkovich","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care, Department of Medicine Medical University of South Carolina Charleston South Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Clayton","family":"Shamblin","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care, Department of Medicine Medical University of South Carolina Charleston South Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephanie R.","family":"Shaftman","sequence":"additional","affiliation":[{"name":"Division of Biostatistics and Epidemiology, Department of Medicine Medical University of South Carolina Charleston South Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul J.","family":"Nietert","sequence":"additional","affiliation":[{"name":"Division of Biostatistics and Epidemiology, Department of Medicine Medical University of South Carolina Charleston South Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jack","family":"Yang","sequence":"additional","affiliation":[{"name":"Division of Cytology, Department of Pathology Medical University of South Carolina Charleston South Carolina"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,9,3]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.12-2355"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/thx.2005.047829"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2013.05.016"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2407-11-100"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2011.11.022"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2010.04.062"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1309\/BLLQF8KDHWW6MJNQ"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/cncy.21350"},{"key":"e_1_2_7_10_1","first-page":"517","article-title":"Transbronchial fine needle aspiration of the mediastinum.
