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 is fundamental in the treatment of primary brain tumours. RT contributes to improved local control and prolonged progression-free survival in patients with a broad range of tumour types. Irradiation to the normal brain may lead to cognitive impairments. Clarifying the nature and severity of impairment in adult RT-treated brain tumour patients, including region-specific effects, are important for optimal utilization of novel conformal RT technologies such as proton therapy. The study is a prospective nationwide study including approximately 300 brain tumour patients from the Danish Center of Particle Therapy and the four Neuro Oncology Centers in Denmark. The patients will be assessed with a comprehensive battery of standardized cognitive tests and complete a questionnaire (PRO's). They will do this prior to RT treatment and 1, 3, 5 and 10 years afterwards. The PRO's includes measures on quality of life, fatigue, sleep, depression, anxiety, and socio demographics. 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. 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.

MeasureTime frameDescription
Impairment of verbal learning and memory as assessed by the HVLT-r test10 YearsExamined by the Hopkins Verbal Learning Test revised. It will be correlated to the mean radiation dose to the hippocampus. Outcome is number of correct words (0-24)

Secondary

MeasureTime frameDescription
Processing speed I10 yearsExamined by the Trail making Test part A (TMT\_A). Outcome for TMT\_A is time in seconds (0-120 seconds).
Processing speed II10 yearsExamined by the Coding from Wechsler Adult Intelligence Scale (WAIS-IV). Outcome for Coding is number of correct (within 2 minutes) (0-100)
Attention and working memory10 yearsExamined by Wechsler Adult Intelligence Scale (WAIS\_IV\_digit\_span). Outcome on WAIS digit span is number of correct (0-36)
Verbal learning and memory10 yearsExamine by the Hopkins Verbal Learning Test revised (HVLT-r) - total and delayed. Outcome is number of correct words (0-24)
Verbal fluency10 yearsExamined 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 I10 yearsExamined by Trail making Test part B (TMT\_B). Outcome for TMT\_B is time in seconds (0-300).
Quality of Sleep10 yearsAssessed by questionnaire: Pittsburgh Sleep Quality INDEX, (PSQI) in order to explore the level of quality of sleep in brain tumour patients who has received radiation therapy. Outcome is a number (0-33)
Global Health - Quality of life10 yearsAssessed by questionnaire; European organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30) in order to examine the level of quality of life in brain tumour patients who has received radiation therapy. The total score is a number (0-100)
Side effects to radiation therapy10 yearsAssessed by EORTC Brain Neoplasm Questionnaire, BN20 (an addition to QLQ-C30 mentioned above) in order to measure side effects to radiation therapy for a brain tumour. the score is a number (0-100)
Fatigue10 yearsAssessed by questionnaire: Functional Assessment of Chronic Illness Therapy (FACIT) - Fatigue scale (version 4) in order to explore the level of fatigue in brain tumour patients who has received radiation therapy. Outcome is a number (0-52)
Depression/Anxiety10 yearsAssessed 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. Outcome is a number (0-56)
Patient's Assessment of Own Functioning10 yearsAssessed by questionnaire; Patient's Assessment of Own Functioning Inventory (PAOFI), in order to assess patients own perception of cognitive function. Outcome is a number (35-210)
Executive function II10 yearsExamined by the STROOP colour and word test (STROOP). Outcome for STROOP is number of corrects (0-120)
