A trial looking at treatment for children and young people with medulloblastoma (CNS 2001 06)
This trial looked at radiotherapy and chemotherapy for children and young people with medulloblastoma that has spread (metastasised).
After surgery, children usually have radiotherapy once a day for 4 to 6 weeks. In this trial, they had radiotherapy twice a day instead of once a day. This is called hyperfractionated accelerated radiotherapy, or HART.
There were two parts to this trial. In the first part, children had HART on its own. In the second part, they had a combination of HART and a chemotherapy drug called vincristine.
The aims of this trial were to
- See how well HART works for medulloblastoma
- Find out more about the side effects
Summary of results
The trial team found that hyperfractionated accelerated radiotherapy (HART) didn’t cause too many side effects, and that it may be a useful treatment for medulloblastoma.
This phase 2 trial recruited 34 children aged 3 to 15 years old who had medulloblastoma that had spread.
The trial was in 2 parts. Everyone taking part had HART. They had radiotherapy twice a day, Monday to Friday, for 5 weeks. In part 1, 7 children had HART on its own. In part 2, 27 children had a combination of HART and vincristine chemotherapy.
Everyone taking part then had what doctors call maintenance chemotherapy, which started a few weeks after they finished radiotherapy.
The research team looked at how well the treatment worked, and found that
- More than 9 out of 10 children (94%) were living 1 year after treatment
- About 8 out of 10 children (81%) were living 2 years after treatment
- About 7 out of 10 children (71%) were living 3 years after treatment
The treatment did cause some side effects. The most common side effects were a sore mouth, feeling or being sick and a drop in blood cells causing an increased risk of infection, bleeding, bruising, tiredness and shortness of breath.
The research team concluded that HART could be a useful treatment for children with medulloblastoma, and that it didn’t cause too many serious side effects. They suggest that it is looked at further in a larger phase 3 trial.
