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.
