hMethods for evaluation include mediastinoscopy, mediastinotomy, EBUS, EUS, and CT-guided biopsy. jPositive PET/CT scan findings for distant disease need pathologic or other radiologic confirmation. If PET/CT scan is positive in the mediastinum, lymph node status needs pathologic confirmation. kSee Principles of Surgical Therapy (NSCL-B). lSee Principles of Radiation Therapy (NSCL-C). bbAggressive local therapy may be appropriate for selected patients with limited-site oligometastatic disease. ccSee NCCN Guidelines for Central Nervous System Cancers. ddMay include adrenalectomy or RT (including SABR). eePatients with N2 disease have a poor prognosis and systemic therapy should be considered.
