Brief Summary

Aim To test if proton therapy can improve survival compared to photon therapy in patients with locally advanced NSCLC who are not candidates for standard definitive chemo-radiotherapy. Hypothesis The trial hypothesis is that proton therapy is less toxic than photon therapy in fragile patients and that this difference will mitigate to a difference in overall survival. Design Multicentre, randomized phase II study 1:1 Sample size 182 patients (91 in each arm) Treatment Radiotherapy (inhomogeneous dose distribution) 50 Gy/ 24 fraction Endpoint Primary: Overall survival at 12 months Secondary: progression free survival, time to loco-regional and distant failure, pattern of failure, acute and late toxicity, quality of life, patient compliance.
