The utility of transbronchial (Wang) fine needle aspiration in lung cancer diagnosis.
We evaluated our experience with transbronchial fine needle aspiration (TBNA) in cancer diagnosis over a period of 1 year. A total of 51 aspirates were performed by specialist chest physicians in the presence of a cytopathologist who made on spot evaluation of Diff-Quik smears for adequacy and guided the aspirator for additional sampling if necessary. Two clusters of at least 10 malignant cells were required on the Diff-Quik smears to render an on the spot positive diagnosis of malignancy. Aspirates showing atypical cells or few malignant cells not fulfilling the above criteria were placed in a suspicious category and additional material was requested. The TBNA results were correlated with the transbronchial biopsy when available.
