Image guided hybrid hyper-fractioned dose escalation with proton therapy

Radiation: Image-guided hybrid hyper-fractioned dose escalation with proton therapy The investigational radiation regime will be administered in a two-part schedule: * The first 4 weeks (i.e. first 20 fractions) of the radiation treatment of the pathological tumor will be according to the conventional clinical standard with proton therapy: 20x 2 Gy to the CTV70 and 20 x 1.55 Gy to the CTV54. * In week 4 (\~ fraction 16) GTV80 will be determined on conventional weekly CT and additional MR imaging (conventional clinical protocol). Only this adapted tumor volume, the so-called GTV80, will receive the dose escalation (i.e., 80.5 Gy). * In the last 3 weeks (last 15 fractions) patients will be radiated twice per day (i.e. hyperfractionation). The GTV80, CTV70 and CTV54 will receive 1.55 Gy in the morning, and the GTV80 and CTV70 will receive additional dose in the afternoon.
