A new trial looking into whether boosting the immune system will help children with an aggressive form of cancer is to be carried out by scientists from Cancer Research UK.

Cancer Research UK said a trial will look into whether immunotherapy, a treatment that encourages the body to hunt down and fight cancer cells, could help children with neuroblastoma, which affects developing nervous system tissue.

The trial will be carried out in the UK, recruiting 40 children over a four-year period.

A recent study in the US found immunotherapy helped improve the chances of survival in patients with neuroblastoma.
