Endobronchial ultrasound-guided transbronchial fine needle aspiration of mediastinal lymphadenopathy : Diagnostic performance and clinical implications of the World Health Organization reporting system
Introduction: Lymph node fine-needle aspiration cytology (LN-FNAC) is a common, rapid, minimally invasive and cost-effective diagnostic method. For mediastinal lymph nodes, endobronchial ultrasound (EBUS) guided LN-FNAC is a first-line investigation and has an indispensable role in the diagnosis and staging of patients with suspected lung cancer. Recently, a new WHO system has been proposed for cl
