BACKGROUND: The aspirates from endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) were examined using the tissue core and cytology. We assessed that the tissue core was a more reliable specimen and attempted to analyze how many discrepancies were found between the two specimens. We investigated diagnostic concordance rate between histology and cytology. METHODS: From January 2011 to December 2011, a total of 267 consecutive patients with lung cancer, who underwent EBUS-TBNA, were included in this retrospective study. RESULTS: Of the 267 lung cancer patients, 207 (77.5%) were men. The median age was 65 years old. The most common pathologic type was adenocarcinoma (120, 44.9%), followed by squamous cell carcinoma (79, 29.6%). Among the 267 patients, 579 mediastinal and hilar lymph nodes were punctured. The right lower paratracheal (204, 35.2%) and subcarinal (172, 29.7%) lymph nodes were the most common nodal stations. Among the 579 lymph nodes, malignant cells were observed in 267 (46.1%) nodes, in either the histologic, cytologic or both slides: 209 in both histology and cytology, 37 in histology only, and 21 in cytology only slides. The diagnostic concordance rate between the tissue core and cytology was 90.0% (95% confidence interval CI, 87.1-92.2) (κ = 0.79). CONCLUSIONS: The diagnostic concordance rate between the histology and cytology of EBUS-TBNA in lung cancer was 90.0% (95% CI, 87.1-92.2) (κ = 0.79).
