BACKGROUND: Endobronchial ultrasound‐guided transbronchial needle aspiration (EBUS‐TBNA) biopsy is routinely used to stage lung cancer; however, its usefulness in diagnosing lymphoproliferative disorders has not been well established. In this retrospective study, we determined the utility of EBUS‐TBNA in evaluating mediastinal lymphadenopathy in patients with suspected lymphoproliferative disorders. METHODS: The authors searched the pathology database at their institution to identify all patients who had undergone EBUS‐TBNA biopsy for possible lymphoproliferative disorders. The cytologic diagnoses were correlated with concurrent and subsequent biopsy findings and clinical follow‐up data. RESULTS: Of 886 lymph nodes evaluated by EBUS‐TBNA biopsy, 91 nodes from 33 patients (23 men and 10 women) were eligible. Fourteen patients had a history of lymphoma. Adequate material for diagnosis was obtained in 31 of 34 procedures (1 patient had 2 procedures). The cytologic diagnoses of the 31 adequate procedures included 19 with benign disease (8 reactive lymph nodes and 11 granulomatous inflammation), 8 with lymphoma (2 large B‐cell, 2 small lymphocytic, 2 Hodgkin, 1 mantle cell, and 1 T‐cell lymphoblastic), 2 with cells suspicious for Hodgkin lymphoma, and 2 cases with atypical cells. CONCLUSIONS: EBUS‐TBNA proved to be useful for evaluating mediastinal lymphadenopathy in patients with suspected lymphoproliferative disorders. Its use may decrease the need for invasive diagnostic procedures. Immediate assessment is valuable in these cases because of the need to triage material for immunophenotyping or other studies to determine optimal and clinically meaningful diagnoses.
