title: Postoperative radiation therapy in non-small cell lung cancer.
abstract: One hundred seventy-three patients with the diagnosis of non-small cell lung cancer (NSCLC) were treated with surgery and postoperative radiation therapy (RT) at the Radiation Oncology Center, Washington University, St. Louis. All patients had been retrospectively reviewed and restaged according to the new American Joint Committee (AJC) staging classification. Seventeen patients were stage I, 69 were stage II, 74 were stage IIIA, and 2 patients were stage IIIB. In 11 patients, accurate staging could not be determined. Indications for postoperative RT were positive surgical margins (32 patients), metastatic hilar nodes (78 patients), and metastatic mediastinal nodes (62 patients). Locoregional control for stages I, II, and IIIA was 85, 75, and 85%, respectively. Five-year actuarial survival was 35% for stage I and 20% for stages II and IIIA. Patients with N0 disease (positive margins) had 5-year survival of 25%, whereas patients with N1 and N2 disease had a 5-year survival of 20%.
