International HIT-MED Registry (I-HIT-MED)

The following patients can be included in this registry: Children and adults with * Medulloblastoma (MB) * Ependymoma * Pineal Tumours * Chroroid plexus tumours Objectives of this registry: To prospectively evaluate the clinical courses of patients with the eligible brain tumours, considering neuroradiological, pathological, and molecular / biological characteristics of the tumour and individual standard treatment data. To collect biological specimens (tumour, CSF, peripheral blood) or their data to perform biological studies on * disease aetiology * molecular / biological risk factors influencing treatment response and survival * potential targets for drug treatment in future patients To assess the use of systems for quality assurance during diagnosis and treatment of brain tumours. To assess long-term follow-up, quality of survival, neuropsychology, and other patient-centred research in these very rare tumour subtypes in the context of the registry or in cooperation with external collaborators.
