7. PORT for Stage II or III NSCLC (SEER Database) N = 7465; Hazard ratio (HR) <1 = improved overall survival. Lally BE, et al. J Clin Oncol. 2006;24:2998-3006. Reprinted with permission from the American Society of Clinical Oncology. Conclusion In a population-based cohort, PORT use is associated with an increase in survival in patients with N2 nodal disease but not in patients with N1 and N0 nodal disease.

Editor's Notes
All patients should undergo a history-taking and physical examination, chest X-ray and chest computed tomography (CT) scans (including the adrenal glands), liver CT scan or abdominal ultrasound. Other evaluations include a complete blood count, electrolytes, liver function tests, calcium, blood urea nitrogen, and creatinine, as well as a baseline ECG. Bone scans and/or brain CT scans may be appropriate in some patients. 1 The extent of the tumor, the involvement of the lymph nodes, and chest wall or mediastinal invasion can be determined with similar efficacy using either CT or MRI. CT is used more commonly, although MRI may be preferable in specific situations, for example in evaluating superior sulcus tumors. 2 Positron emission tomography (PET) with radiolabeled fluoro-2-deoxyglucose combined with CT was significantly more accurate than CT alone in identifying lymph node involvement in NSCLC. 3 1.
