About this trial
This study investigates the effects of brain radiotherapy on cognitive function by evaluating plasma biomarkers and apolipoprotein E (APOE) genotype in patients with primary or metastatic brain tumors. Standard brain radiotherapy is known to impact cognitive outcomes, yet the underlying biological mechanisms remain unclear.
Eligibility criteria

Trial outcomes
Primary outcomes
Mean change in serum Amyloid-beta peptide (Aβ)
Mean change in biomarker for Aβ over time will be reported
Mean change in serum Amyloid-beta peptide (Aβ) by APOE genotype
Mean change in biomarker for Aβ by APOE genotype over time will be reported
Mean change of score on the European Organization for Research and Treatment of Cancer quality of life questionnaire - Brain Module (EORTC-QLQ-BN20)
The EORTC QLQ-BN20 consists of 20 questions; seven single item symptom scales (headaches, seizures, drowsiness, hair loss, itchy skin, leg weakness and bladder control), along with four multi-item scales (future uncertainty, visual disorder, motor dysfunction and communication deficit). Raw scores for the QLQ-BN20 items are computed by calculating the mean of the items in each subscale, or the item for each individual and linearly transform the scores to a 0-100 scale. A higher score represents worse QOL for all QLQ-BN20 scales and single items.
Mean change in serum Glial Fibrillary Acidic Protein (GFAP)
Mean change in biomarker for GFAP over time will be reported
Secondary outcomes
Change in scores on the European Organization for Research and Treatment of Cancer quality of life questionnaire 30 (EORTC-QLQ-C30) over time
The functional domains measure the quality of life in Physical functioning, Role functioning, Emotional functioning, Cognitive functioning, Social functioning. Scores consists of responses to items with responses ranging from 1="Not at all" to 4="Very Much". The raw score is calculated by estimating the mean of the items that make up each domains with a resulting total range of 1 - 4. These scores are then transformed to standardized scale score, so that scores range from 0 to 100. A high score for the functional domains represents a high level of functioning.
