This study is a randomized multicentric trial. Within this study an accelerated irradiation schedule (7 fractions per week, 2 Gy single dose) will be compared with the currently used conventional fractionation schedule (5 fractions per week, 2 Gy single dose) for postoperative radiotherapy with photons or protons in patients with NSCLC. The primary endpoint is locoregional tumour control after 36 months. Secondary endpoints are overall survival of patients, local recurrence-free and distant metastases-free survival after 36 months, acute and late toxicity as well as quality of life for both treatment methods.
