AbstractDuring the staging process of lung cancer, accurate mediastinal lymph node staging is one of the more important factors that affects patient outcome. Several different invasive and non-invasive modalities exist for mediastinal staging. Invasive tests include mediastinoscopy, thoracoscopy, transbronchial needle aspiration, transthoracic needle aspiration, endoscopic ultrasound-guided fine-needle aspiration and endobronchial ultrasound-guided transbronchial needle aspiration. Each of the invasive tests has limitations for particular locations, has particular risks and requires specific skills. Invasive tests are often used to confirm the staging of lung cancer, but are also used to obtain a diagnosis. The best approach depends upon the clinician's assessment of the patient. This review discusses the invasive staging tests that are available, with particular emphasis on newer modalities, especially endobronchial ultrasound-guided transbronchial needle aspiration. In addition, the current advances in diagnostic bronchoscopy for lung cancer will be reviewed.
