Diagnostic performance of EBUS\u2010TBNA in lymphoma using standard 22\u2010gauge (22G) needle is limited by sample volumes that are often inadequate for histopathological assessment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objectives<\/jats:title><jats:p>To evaluate the diagnostic utility of 19\u2010gauge (19G) EBUS\u2010TBNA needle in the evaluation of suspected lymphoma.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We prospectively collected clinical and procedural information for patients undergoing EBUS\u2010TBNA with 19G needle at Royal Melbourne Hospital for investigation of mediastinal\/hilar lymphadenopathy, where lymphoma was considered in the differential diagnosis. All consecutive patients between June 15, 2016 and July 10, 2019 were included. If definitive diagnosis was not achieved on EBUS\u2010TBNA, final diagnosis was determined through subsequent investigation or a minimum of 6 months radiologic surveillance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thirty\u2010nine patients underwent EBUS\u2010TBNA using 19G needle for evaluation of suspected lymphoma. Thirteen patients had a prior diagnosis of lymphoma (33%). Lymphoma was ultimately diagnosed in 23 patients (59%). Of these, 10 had a prior diagnosis of lymphoma (43%). 19G EBUS\u2010TBNA demonstrated lymphoma in 19 patients, with a sensitivity of 83% (95% CI 66\u201093) for detection of lymphoma. Four patients required surgical biopsy to definitively characterise lymphoma subtype. Therefore, sensitivity of 19G EBUS\u2010TBNA for definitive diagnosis of lymphoma was 65% (95% CI 45\u201081). In patients with a prior diagnosis of lymphoma, sensitivity for definitive diagnosis of lymphoma was 80% (95% CI 48\u201095).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Diagnostic performance of 19G EBUS\u2010TBNA appears similar to standard 22G needle in detection and definitive diagnosis of lymphoma.
