Assessing cognitive function in brain tumor patients after radiation therapy

Cognitive Function After Radiation Therapy for Primary Brain Tumours

University of Aarhus · NCT04306432

This study is trying to see how radiation therapy affects thinking skills over time in patients with primary brain tumors, except glioblastoma, by checking their cognitive function at different points after treatment.

What this trial studies

This observational study evaluates cognitive function in patients with primary brain tumors who have undergone radiation therapy. It aims to identify the relationship between radiation dose and cognitive impairment by assessing patients at multiple time points: before treatment and at 1, 3, 5, and 10 years post-treatment. A comprehensive battery of standardized cognitive tests and patient-reported outcomes will be utilized to gather data on cognitive performance and quality of life. The study includes various types of brain tumors, excluding glioblastoma, and is conducted across multiple centers in Denmark.

Who should consider this trial

Good fit: Ideal candidates are Danish-speaking adults aged 18 and older with specific types of primary brain tumors, excluding glioblastoma.

Not a fit: Patients with glioblastoma or those with a performance status of 3-4 will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of cognitive impairments in brain tumor patients receiving radiation therapy.

How similar studies have performed: While studies on cognitive function post-radiation exist, this study's specific focus on dose-response relationships in various brain tumor types is relatively novel.
