Endoscopic ultrasonography/fine-needle aspiration and endobronchial ultrasonography/fine-needle aspiration for lung cancer staging.

This article reviews different techniques available for diagnosis and staging of patients with non-small cell lung cancer (NSCLC). The advantages and disadvantages of each staging method are highlighted. The role of the gastroenterologist in NSCLC staging is explored. A new algorithm is proposed for the staging of NSCLC that incorporates endoscopic and endobronchial ultrasonography for mediastinal staging in patients with intrathoracic disease.
