- late toxicity as cumulative measure [ Time Frame: 1 year after end of treatment ]
Events for the endpoint are:
- any late toxicity CTCAE 4.0 ≥ grade II (except pre-existing conditions)
- decrease in Quality of life (EORTC-QLQ-C30 and BN20) by >10%
- decrease in brain function (MOCA test) by more than 10%
- Local tumour control [ Time Frame: 1 year and 2 years ]Local tumour control as Regression or stable disease measured in follow-up MRI
- Overall survival [ Time Frame: 1 year and 2 years ]
- acute toxicity [ Time Frame: 3 months after treatment ]acute toxicity according to CTCAE4.0 score >/= grade II
- late toxicity as cumulative measure [ Time Frame: 2 years ]
Events for the endpoint are:
- any late toxicity CTCAE 4.0 ≥ grade II (except pre-existing conditions)
- decrease in Quality of life (EORTC-QLQ-C30 and BN20) by >10%
- decrease in brain function (MOCA test) by more than 10%

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- primary brain tumor: gliomas (low or high grade), intracerebral meningiomas, pituitary adenomas, craniopharyngioma and other rare brain tumors
- brain tumor recurrence without pre-irradiation
- brain tumor recurrence with pre-irradiation > 40 Gy in the overlap region with the recurrence region
- indication for radiotherapy or radiochemotherapy
- Both proton and photon therapy are possible from a medical point of view (that is no standard indication for protons or standard indication for example one-time stereotaxy
- age >= 18 years
- general condition ECOG ≤ 2, outpatient basis possible
- indication for high dose (except group 4) radiotherapy or radiochemotherapy
- capacity to consent and present written informed consent
Exclusion Criteria:
- lack of capacity to consent or lack of written consent
- cerebral lymphomas
- brain metastases
- very small tumors (for example acoustic neuromas, very small recurrences) for this is a proton therapy from a medical point of view no alternative to a stereotactic radiotherapy
- inability to MRI planning (eg. contraindications to performing MRI)
- lack of compliance of the patient
- lack of or limited possibility of a reproducible storage (eg by severe restriction of mobility of the patient)
- missing or limited possibility of regular follow-up visits in accordance with the study protocol
