Often, they include combined induction chemotherapy and consolidation with high dose chemotherapy followed by autologous stem cell rescue. Radiation therapy is sometimes attempted, but may result in cognitive impairment in young children.

The 5-year survival rate for children with leukemia is 83.6% in the USA. This means that 83.6% of children diagnosed with leukemia live for 5 years or more after their diagnosis. This is greatly improved from a 5-year survival rate of 36.5% in 1975. The improvement is largely attributed to advances in therapy, particularly therapy for ALL.
Medulloblastomas affect just under two people per million per year, and affect children 10 times more than adults. [36] Medulloblastoma is the second-most frequent brain tumor in children after pilocytic astrocytoma [37] and the most common malignant brain tumor in children, comprising 14.5% of newly diagnosed brain tumors. [38]
In underdeveloped nations with high rates of malnutrition and poor healthcare, fatality rates have been as high as 28%. [49] In immunocompromised persons (e.g., people with AIDS) the fatality rate is approximately 30%. [50] Even in previously healthy children, measles can cause serious illness requiring hospitalization. [46]
Pleomorphic xanthoastrocytoma (PXA) is a brain tumor that occurs most frequently in children and teenagers. At Boston Children's Hospital, the average age at diagnosis is 12 years.
