Role of EBUS TBNA in staging of lung cancer: A clinician's perspective

The treatment of non-small cell lung cancer (NSCLC) includes surgical resection with curative intent in early-stage disease and chemoradiation in the advanced stage disease. Therefore, an accurate preoperative mediastinal lymph node staging is required not only to offer the appropriate treatment but also to avoid unnecessary invasive procedures including thoracotomy. The mediastinal lymph nodes can be sampled using several techniques including mediastinoscopy, surgery (open or video-assisted thoracoscopic surgery), endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA), or endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA). Currently, EBUS-TBNA/EUS-FNA is the preferred modality for sampling mediastinal lymph nodes because of its minimally invasive nature and high diagnostic yield. In this review, we discuss the utility of endosonographic procedures in mediastinal lymph node staging of NSCLC.
