Can less radiation still beat childhood brain cancer?

NCT ID NCT00085735

Completed Disease control Sponsor: Children's Oncology Group Source: ClinicalTrials.gov ↗

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This trial studies whether giving a lower dose of radiation to the brain and spine, along with a smaller radiation boost to the tumor site, works as well as standard radiation when combined with chemotherapy in children aged 3–7 with newly diagnosed standard-risk medulloblastoma. All children had surgery to remove the tumor before starting treatment. The goal is to see if reducing radiation can maintain cancer control while possibly lowering long-term side effects.

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 (craniospinal and boost), cisplatin, vincristine, lomustine, cyclophosphamide

What this could lead to

If successful, this could allow children with medulloblastoma to receive less radiation, potentially reducing long-term side effects while still controlling the cancer.

What could go wrong

This is a phase III trial, but results may show that lower radiation is less effective at preventing recurrence. Chemotherapy also carries risks like infection, nerve damage, and kidney problems.
