Flexible transbronchial needle aspiration for staging of bronchogenic carcinoma.
Flexible transbronchial needle aspiration (TBNA) provides access to mediastinal lymph nodes, but its role in staging bronchogenic carcinoma is unknown. To determine the efficacy and safety of this procedure for staging the extent of mediastinal disease, the results of TBNA performed during fiberoptic bronchoscopy in 39 patients without known extrathoracic metastases were reviewed. Flexible TBNA was found to be a safe, effective method for determining the presence or absence of mediastinal metastases from bronchogenic carcinoma. Furthermore, TBNA results compare favorably with roentgenographic staging techniques, with the added advantage of providing cytopathologic information.
