Newly Diagnosed WHO Grade II–III Cerebral Ependymoma in a Child with CSF or Spinal Dissemination

This protocol addresses a specific pediatric scenario: a child presenting with newly diagnosed intracranial ependymoma (WHO grade II or III) in whom cerebrospinal fluid (CSF) or spinal dissemination has been identified at diagnosis.

Clinical Scenario

The presence of CSF or spinal dissemination at the time of diagnosis defines this sub-population. This finding directly shapes the treatment strategy and the extent of radiation targeting required, distinguishing this presentation from localised disease.

Treatment Approach

The management of this scenario centres on craniospinal irradiation (CSI) to address neuraxis involvement, combined with targeted boosting of focal lesions. The complete dosing strategy — including how doses are adapted to patient age — is specified in the full structured protocol.

Full regimen details, decision points, and dosing parameters available below.
