Brief Summary
Given that the cost of proton therapy is considerably higher than that of conventional radiotherapy with photons, it is necessary to establish whether these higher costs are worthwhile in light of the expected advantages2,3,4. Thus, clear evidence of the situations in which proton therapy outperforms conventional photon treatment is needed. The investigators therefore aim to demonstrate through an in silico trial that proton therapy decrease the amount of irradiated normal tissue and, consequently, the risk of side effects in the surrounding normal tissue as well as the risk of secondary tumors. The same overall treatment time and an equal number of fractions will be used for both treatment modalities wherever possible. The most optimal technique for each individual patient, based on objective criteria related to limiting dose to normal tissue, will be prescribed by the institution concerned for each treatment option.

Outcome Measures
Primary Outcomes (1)
Radiation exposure for organs at risk in H&N cancer patients
Radiation exposure for organs at risk in H\&N patients treated with radiotherapy for recurrent tumors after primary radiotherapy. Results are based on in silico planning study which compares photon, proton and Carbon-ion treatments. The same biological radiation dose, fractionation schedule and tumor dose inhomogeneity is used. A wide range of OAR is included in this study, to be able to document doses to organs that are further away from the target volume, and also to quantify low doses to organs.
