Postoperative radiotherapy in resected N2 non-small-cell lung cancer: Lung ART.

Abstract

For more than 20 years, the role of postoperative radiotherapy (PORT) has been controversial in patients with completely resected (R0) N2 non-small-cell lung cancer (NSCLC), because no contemporary clinical trials with adequate staging and treatment were available. Postoperative radiotherapy versus no postoperative radiotherapy in patients with completely resected non-small-cell lung cancer and proven mediastinal N2 involvement (Lung ART, IFCT 0503): an open-label, randomised, phase 3 trialLung ART evaluated 3D conformal PORT after complete resection in patients who predominantly had been staged using (18F-FDG PET-CT and received neoadjuvant or adjuvant chemotherapy. 3-year disease-free survival was higher than expected in both groups, but PORT was not associated with an increased disease-free survival compared with no PORT. Conformal PORT cannot be recommended as the standard of care in patients with stage IIIAN2 NSCLC. Full-Text PDF
