Uitkomstmaten
Primaire uitkomstmaten
Cognitive functioning will be examined with a battery of neuropsychological tests: The revised Hopkins Verbal Learning Test (HVLT-R), WAIS Digit Span and Digit Symbol, TMT A and B, COWA, and Grooved Pegboard.
Achtergrond van het onderzoek
Effective treatment for patients with brain metastases (BM) without negative cognitive side effects is increasingly becoming more important, since more patients survive and live longer after treatment. The proposed study is a single-arm, prospective study designed to evaluate changes over time in cognitive function in adult patients with BM scheduled for treatment with GKRS in the Netherlands. Neuropsychological assessment will be performed at baseline (before GKRS). Follow-up at 3, 6, 9, 12, 15, and 21 months (cognitive testing) and 3-monthly MRI scan. Ultimately, the purpose of this line of research is to inform individual patients with BM more precisely about the (long-term) cognitive effects and the consequences they can expect from treatment with GKRS. This will enable patients and doctors to make a better-informed treatment decision grounded on scientific evidence.
Doel van het onderzoek
The main objective is to assess cognitive functioning over time in patients with multiple (1-10) brain metastases (BM) after Gamma Knife Radiosurgery (GKRS). Improvements and/or declines in memory, executive function, attention, processing speed, and upper extremity fine motor dexterity will be determined at baseline (before GKRS treatment) and subsequent follow-ups.
Onderzoeksopzet
The neuropsychological test battery, including questionnaires, will be administered at baseline (before GKRS) and 3, 6, 9, 12, 15 and 21 months after treatment.
Onderzoeksproduct en/of interventie
Patients will complete a standardized battery of neuropsychological test both at baseline
and 3, 6, 9, 12, 15, and 21 months post GKRS.
