Cytological assessment of conventional transbronchial fine needle aspiration of lymph nodes Objectives: Transbronchial fine needle aspiration (TBNA) is a minimally invasive bronchoscopic technique that allows pathological examination of mediastinal and hilar lymph nodes. The aim of this study was to assess the cytopathological outcome of TBNA. Methods: One hundred and eighty‐seven patients who underwent TBNA of mediastinal and hilar lesions from May 2000 to June 2007 were reviewed. Results: TBNA results were considered to be adequate if the cytological material revealed a malignant lesion or sufficient number of benign lymphoid cells. In the current study, 40 cases (21.9%) were reported as inadequate. When inadequate tests were excluded, the overall sensitivity and accuracy of TBNA in the diagnosis of malignant lesions were 83.5% and 88.0% respectively. The lowest sensitivity was noted in lymph node involvement by lymphoma. Regarding the workload associated with TBNA cytology, we found that the average number of conventionally prepared cytological slides per case was high (17 slides per case). Conclusion: Our results confirm that conventional TBNA is a sensitive and useful technique but it is relatively expensive and the protocols should be adapted to allow appropriate material to be collected for ancillary diagnostic tests.
