Radiation showdown: which schedule beats childhood brain cancer?
NCT ID NCT01351870
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This trial tested two different ways of giving radiation to children and teens with a standard-risk brain tumor called medulloblastoma. One group got standard daily radiation, while the other got smaller doses twice a day. The goal was to see which schedule better prevents the cancer from coming back. The study enrolled 52 participants aged 4 to 21.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Radiation therapy
- What this could lead to
- If successful, this could identify a more effective radiotherapy schedule for children with medulloblastoma, potentially improving disease control and survival.
- What could go wrong
- This is a completed Phase 3 trial with only 52 participants, so results may not apply broadly. Both regimens involve radiation, which carries risks of long-term side effects.

Inclusion Criteria: * Age at diagnosis at least 4 years or 5 years (according to the policy of the National Brain Tumour Group) and less than 22 years. * Histologically proven medulloblastoma, including the following variants(WHO classification - 2000): classic medulloblastoma, nodular / desmoplastic medulloblastoma, melanotic medulloblastoma, medullomyoblastoma No CNS metastasis on MRI - supratentorial, arachnoid of the posterior fossa or spine. * No clinical evidence of extra-CNS metastasis * No tumour cells on the cytospin of lumbar CSF. Central Review of CSF cytology is recommended but not mandatory. It will be left to national policy. * Radiotherapy to start no more than 40 days after surgery. * Ability to receive twice daily radiotherapy. * Vital functions within normal range for their age group. * CTC grades \< 2 for liver, renal, haematological and audiological function. * No medical contraindication to radiotherapy or chemotherapy. * Written informed consent (and patient assent where appropriate) according to the laws of each participating country. Written informed consent should also be sought for biological studies. * National and local ethical committee approval according to the laws of each participating country (to include approval for biological studies). Exclusion Criteria: * One of the inclusion criteria is lacking. * Brainstem or supratentorial primitive neuroectodermal tumour. * Atypical teratoid rhabdoid tumour. * Medulloepithelioma. * Ependymoblastoma. * Large cell médulloblastoma. * Metastatic medulloblastoma (on CNS MRI and/or positive cytospin of postoperative lumbar CSF). * Patient previously treated for a brain tumour or any type of malignant disease. * Patients who are pregnant. * Females who are sexually active and not taking reliable contraception. * Known predisposition to medulloblastoma e.g. Gorlin's syndrome.
