Understanding Cerebellar Mutism Syndrome in Pediatric Brain Tumor Patients

Nordic Study of the Cerebellar Mutism Syndrome in Children With Brain Tumours of the Posterior Fossa

Observational Rigshospitalet, Denmark · NCT02300766

This study looks at why some kids who have surgery for brain tumors develop Cerebellar Mutism Syndrome and aims to find better ways to help them.

What this trial studies

This observational study aims to investigate why up to 25% of pediatric patients who undergo surgery for posterior fossa tumors develop Cerebellar Mutism Syndrome (CMS). It will explore the clinical course, risk factors, and potential treatments for CMS by collecting clinical data and imaging from a minimum of 500 patients across multiple centers in the Nordic countries. The study began in 2014 and includes genetic analysis through blood samples to further understand the syndrome's etiology. The findings could lead to improved management strategies for affected children.

Who should consider this trial

Good fit: Ideal candidates are pediatric patients under 18 years old with tumors located in the cerebellum, fourth ventricle, or brainstem who are undergoing surgical treatment.

Not a fit: Patients with tumors outside the specified brain regions or those over 18 years old will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and treatment options for children suffering from Cerebellar Mutism Syndrome.

How similar studies have performed: While similar studies have explored pediatric brain tumors, the specific focus on Cerebellar Mutism Syndrome in this context is relatively novel.
