Staging outcomes of patients with NSCLC and no enlarged mediastinal lymph nodes on CT. After CT scan, patients underwent EUS. If no advanced disease (AJCC stage III/IV) was confirmed, invasive staging was performed. If no advanced disease was confirmed on mediastinoscopy, thoracoscopy, or bronchoscopy, a thoractomy and complete mediastinal lymph node resection was performed. (AJCC = American Joint Committee on Cancer; CT = computed tomography; EUS-FNA = endoscopic ultrasound guided fine-needle aspiration; LN = lymph node; NSCLC = nonsmall cell lung cancer; Pts = patients.)
