Brief summary
This study will assess cognitive function in patients with a primary brain tumour treated with radiation therapy (RT) to generate radio-sensitivity and volume effect parameters for the development of cognitive dysfunction. All types of brain tumours apart from glioblastoma will be included.
Detailed description
RT to brain tumours causes cognitive dysfunction. The extent of RT induced changes in cognitive function and radio-sensitivity of the brain is unknown. RT with protons instead of photons spares the healthy brain tissue more and is believed to reduce the risk of cognitive dysfunction. There is modest knowledge on which parts of the brain we need to spare, to prevent cognitive dysfunction. The study is a prospective nationwide study including approximately 60 brain tumour patients from the four neuro oncology centres in Denmark. The patients will do patient reported outcome (PRO) and undergo neuropsychological assessment with standardized tests: They will do this prior to RT treatment and ½, 1, 3 and 5 years afterwards. The PRO's included measures on quality of life, fatigue, sleep, depression, anxiety, and socio demografica. The standardized tests are: Trail making Test (TMT); Hopkins Verbal Learning Test (HVLT); Controlled Oral Word Association Test (COWAT) - Animals and S; Coding and Digit Span from WAIS-IV; Paced Auditory Serial Addition Test (PASAT). The correlation between cognitive scores and RT dose-volume parameters to specific areas in the brain will be tested. This study will elucidate the dose-response relationship in radiation-induced damage to substructures of the brain such as hippocampus, thalamus, temporal and frontal lobes that will allow the clinician to prioritize these structures in planning of proton radiotherapy.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Impairment of memory as assessed by the HVLT-r test | 5 Years | Examined by the Hopkins Verbal Learning Test. It will be correlated to the mean radiation dose to the hippocampus. Outcome is number of correct words (0-24) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Attention and working memory | 5 Years | Examined by WAIS\_IV\_digit\_span and PASAT (Pased Auditory Seriel Addition Test). Outcome on WAIS digit span is number of correct (0-36) and outcome for PASAT is number of incorrects (0-60) |
| Verbal learning and memory | 5 Years | Examine by the Hopkins Verbal Learning Test (HVLT) - total and delayed. Outcome is number of correct words (0-24) |
| Verbal fluency | 5 Years | Examined by the Controlled Oral Word Association Test (COWAT) - Animals and letter\_S. Outcome is number of words produced in 1 minute (0-100) |
| Executive function | 5 Years | Examined by Trail making Test part B (TMT-B) and the STROOP colour and word test (STROOP). Outcome for TMT\_B is time in seconds (0-300). Outcome for STROOP is number of corrects (0-120) |
| Processing speed | 5 Years | Examined by the Trail making Test part A (TMT\_A) and the Coding from WAIS-IV. Outcome for TMT\_A is time in seconds (0-120 seconds). Outcome for Coding is number of correct (within 2 minutes) (0-100) |
| Fatigue | 5 years | Assessed by questionnaire: FACIT-Fatigue scale (version 4) in order to explore the level of fatigue in brain tumour patients who has received radiation therapy. |
| Qulity of Sleep | 5 years | Assessed by questionnaire:Pittsburg Sleep Quality INDEX, PSQI in order to explore the level of quality of sleep in brain tumour patients who has received radiation therapy |
| Depression/Anxiety | 5 years | Assessed by questionnaire: Hospital anxiety and depression Scale (HADS) in order to explore level of depression and anxiety in patients treated with radiation therapy for their brain tumour |
| Patient's Assessment of Own Functioning Inventory | 5 years | Assessed by questionnaire; Patient's Assessment of Own Functioning Inventory (PAOFI), in order to assess patients own perception of cognitive function |
| Global Health - Quality of life | 5 Years | Assessed by questionnaire; EORTC QlQ-C30 in order to examine the level of quality of life in brain tumour patients who has received radiation therapy. Quality of life will be assessed by EORTC QIQ-C-30 |
