Childhood Acute Lymphoblastic Leukemia Treatment (PDQ®): Treatment - Health Professional Information [NCI] - General Information About Childhood Acute Lymphoblastic Leukemia (ALL)

Fortunately, cancer in children and adolescents is rare, although the overall incidence of childhood cancer has been slowly increasing since 1975.[1] Children and adolescents with cancer should be referred to medical centers that have a multidisciplinary team of cancer specialists with experience treating the cancers that occur during childhood and adolescence. This multidisciplinary team approach incorporates the skills of the following health care professionals and others to ensure that children receive treatment, supportive care, and rehabilitation that will achieve optimal survival and quality of life:

  • Primary care physician.
  • Pediatric surgical subspecialists.
  • Radiation oncologists.
  • Pediatric medical oncologists/hematologists.
  • Rehabilitation specialists.
  • Pediatric nurse specialists.
  • Social workers.

(Refer to the PDQ Supportive and Palliative Care summaries for specific information about supportive care for children and adolescents with cancer.)

Guidelines for pediatric cancer centers and their role in the treatment of pediatric patients with cancer have been outlined by the American Academy of Pediatrics.[2] Because treatment of children with acute lymphoblastic leukemia (ALL) entails many potential complications and requires intensive supportive care (e.g., transfusions; management of infectious complications; and emotional, financial, and developmental support), this treatment is best coordinated by pediatric oncologists and performed in cancer centers or hospitals with all of the necessary pediatric supportive care facilities. It is important that the clinical centers and the specialists directing the patient's care maintain contact with the referring physician in the community. Strong lines of communication optimize any urgent or interim care required when the child is at home.

Dramatic improvements in survival have been achieved in children and adolescents with cancer.[1] Between 1975 and 2002, childhood cancer mortality has decreased by more than 50%. For ALL, the 5-year survival rate has increased over the same time from 60% to 89% for children younger than 15 years and from 28% to 50% for adolescents aged 15 to 19 years.[1,3] Childhood and adolescent cancer survivors require close follow-up because cancer therapy side effects may persist or develop months or years after treatment. (Refer to the PDQ summary on Late Effects of Treatment for Childhood Cancer for specific information about the incidence, type, and monitoring of late effects in childhood and adolescent cancer survivors.)

Incidence and Epidemiology

ALL is the most common cancer diagnosed in children and represents 23% of cancer diagnoses among children younger than 15 years. ALL occurs at an annual rate of approximately 30 to 40 cases per million people in the United States.[4,5] There are approximately 2,900 children and adolescents younger than 20 years diagnosed with ALL each year in the United States.[5,6] Over the past 25 years, there has been a gradual increase in the incidence of ALL.[7]

A sharp peak in ALL incidence is observed among children aged 2 to 3 years (>80 cases per million per year), with rates decreasing to 20 cases per million for ages 8 to 10 years. The incidence of ALL among children aged 2 to 3 years is approximately fourfold greater than that for infants and is nearly tenfold greater than that for adolescents aged 16 to 21 years.
