Incidence of the most common nodal stations for patients with proven N2 disease, based on the lobar location of the primary nonsmall cell lung cancer (NSCLC). For example, of the 372 patients who had a right upper lobe NSCLC, 102 patients had N2 disease. It was most commonly (23% of the time) located in the 4R lymph node station. It was located in the 2R nodal station in 17% of those 102 patients.

Types of minimally invasive procedures available for N2 biopsy and the reported accuracy for each test. (* = superior portion only; checkmark = nodal station is accessible by this modality; EUS-FNA = endoscopic ultrasound–fine-needle aspiration; L = left; Med = mediastinoscopy; ? = maybe, conflicting data on the accuracy at these stations; R = right; VATS = video-assisted thoracoscopy.)
