SALINAS F, MAURICIO et al. Utility of cytology by transbronchial needle aspiration for diagnosing mediastinal nodal involvement in lung cancer staging. Rev. chil. enferm. respir. [online]. 2014, vol.30, n.1, pp.15-19. ISSN 0717-7348.  http://dx.doi.org/10.4067/S0717-73482014000100003.

Introduction: Mediastinal nodal involvement is essential in lung cancer staging. This can be performed with transbronchial needle aspiration using a flexible bronchoscope. We present the experience of the Instituto Nacional del Tórax. Material and Methods: Retrospective study. The procedure was performed in patients with mediastinal nodes greater than 1 cm on computed tomography of the chest. Results: In 132 bronchoscopies, 136 transbronchial needle aspirations for cytological studies were performed, 98 (72%) in subcarinal nodes and 38 (28%) in other locations. In 64 (47.1%) samples, lung cancer was diagnosed. In 100 (73,5%) cases the final diagnosis was lung cancer with mediastinal involvement. In this series transbronchial needle aspiration had a sensitivity of 64% for lung cancer diagnosis. There were no complications. Conclusions: Transbronchial needle aspiration cytology is safe and useful for the diagnosis and staging of the mediastinum in lung cancer patients.
