The outlook for childhood ALL depends on

  • the child's age

  • the child's white blood cell count at diagnosis

  • the disease's response to the initial treatment

  • the child's gender and race

  • whether the disease began from B lymphocytes or T lymphocytes

  • the presence of specific genetic changes

  • whether the cancer has spread to the brain and/or spinal cord

  • whether the child has Down syndrome.

Survival rates for children with ALL have risen over time, thanks to advances in treatment. More than 80% of children with ALL live at least five years.
