The aim of this study was to determine the diagnostic yield, safety profile, and adequacy of specimens obtained using ENB for molecular testing. This single-center, prospective pilot study recruited patients with peripheral pulmonary nodules that were not suitable for biopsy via percutaneous transthoracic needle biopsy methods. The possibility of molecular testing, including epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), and programmed death ligand 1 (PD-L1), was identified with non-small cell lung cancer (NSCLC) tissue obtained using ENB. ENB-guided biopsy was performed on 30 pulmonary nodules in 30 patients. ENB-guided biopsy was successfully performed in 96.6% (29\/30) of cases, but one case failed to approach the target lesion. The diagnostic accuracy of ENB-guided biopsy was 68.0% (17\/25). Biopsy-related pneumothorax occurred in one patient and there was no major bleeding or deaths related to the procedure. Among 13 patients diagnosed with NSCLC, molecular testing was successfully performed in 92.3% (12\/13). ENB-guided biopsy demonstrated acceptable accuracy and excellent sample adequacy, with a high possibility of achieving molecular testing and a good safety profile to evaluate peripheral pulmonary nodules, even when the percutaneous approach was difficult and\/or dangerous.<\/jats:p>","DOI":"10.3390\/diagnostics11081432","type":"journal-article","created":{"date-parts":[[2021,8,9]],"date-time":"2021-08-09T05:17:06Z","timestamp":1628486226000},"page":"1432","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Diagnostic Performance of Electromagnetic Navigation Bronchoscopy-Guided Biopsy for Lung Nodules in the Era of Molecular Testing"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0756-3810","authenticated-orcid":false,"given":"Ju Hyun","family":"Oh","sequence":"first","affiliation":[{"name":"Asan Medical Center, Department of Pulmonary and Critical Care Medicine, University of Ulsan College of Medicine, Seoul 05505, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang-Min","family":"Choi","sequence":"additional","affiliation":[{"name":"Asan Medical Center, Department of Pulmonary and Critical Care Medicine, University of Ulsan College of Medicine, Seoul 05505, Korea"},{"name":"Asan Medical Center, Department of Oncology, University of Ulsan College of Medicine, Seoul 05505, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seulgi","family":"Kim","sequence":"additional","affiliation":[{"name":"Asan Medical Center, Department of Pulmonary and Critical Care Medicine, University of Ulsan College of Medicine, Seoul 05505, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Se Jin","family":"Jang","sequence":"additional","affiliation":[{"name":"Asan Medical Center, Department of Pathology, University of Ulsan College of Medicine, Seoul 05505, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang Young","family":"Oh","sequence":"additional","affiliation":[{"name":"Asan Medical Center, Department of Radiology, University of Ulsan College of Medicine, Seoul 05505, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mi Young","family":"Kim","sequence":"additional","affiliation":[{"name":"Asan Medical Center, Department of Radiology, University of Ulsan College of Medicine, Seoul 05505, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hee Sang","family":"Hwang","sequence":"additional","affiliation":[{"name":"Asan Medical Center, Department of Pathology, University of Ulsan College of Medicine, Seoul 05505, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7164-2770","authenticated-orcid":false,"given":"Wonjun","family":"Ji","sequence":"additional","affiliation":[{"name":"Asan Medical Center, Department of Pulmonary and Critical Care Medicine, University of Ulsan College of Medicine, Seoul 05505, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"877","DOI":"10.1016\/j.chest.2016.02.650","article-title":"Evaluation of Pulmonary Nodules: Clinical Practice Consensus Guidelines for Asia","volume":"150","author":"Bai","year":"2016","journal-title":"Chest"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"311","DOI":"10.7326\/M13-2316","article-title":"Benefits and harms of computed tomography lung cancer screening strategies: A comparative modeling study for the U.S. Preventive Services Task Force","volume":"160","author":"Meza","year":"2014","journal-title":"Ann.
