The study team found that the most important factors to determine whether glioma started to grow again were the age of the child at diagnosis and whether the tumour could be completely removed with surgery.
This trial was the UK group (cohort) of an international trial.
For the UK group the researchers looked at 637 children who had glioma to see what age they were when they were diagnosed
- 28 were less than 1 year old
- 101 were aged between 1 and 3
- 110 were aged between 4 and 5
- 213 were aged between 6 and 10
- 187 were older than 10
After an average of about 5 years follow up, they looked at how many children’s tumours had started to grow again. They found that the glioma had started to grow again in
- 17 children who were less than 1 year old when diagnosed
- 40 children who were between 1 and 3 when diagnosed
- 44 children who were between 4 and 5 when diagnosed
- 42 children who were between 6 and 10 when diagnosed
- 36 children who were older than 10 when diagnosed
After 5 years follow up the trial team looked at the whole group of children. They found that over 94 out of every 100 children (94.6%) were still alive and that for over 64 out of every 100 (64.9%) their tumour had not come back.
The trial team found that many factors determined if the tumour was more likely to start growing again. But they concluded that the 2 most important factors were age (tumours were more likely to come back if the child was diagnosed up to and including the age of 5) and having a tumour that could not be completely removed with surgery.
The results of this trial have been used as the basis for further ongoing international trials.
