Acute lymphoblastic leukemia (ALL) is the most common type of cancer and leukemia in children in the United States. ALL accounts for 75% of pediatric leukemia cases. [8]

In adults, this disease is less common than acute myeloid leukemia (AML). It is estimated that there will be 5960 cases of ALL (adult and pediatric) in the United States in 2018, resulting in 1470 deaths. [9] The estimated 5 year survival is 68.2%. The favorable survival rate is due to the high cure rate of ALL in children. Prognosis declines with increasing age, and the median age at death is 55 years. [8]

Worldwide, the highest incidence of ALL occurs in Italy, the United States, Switzerland, and Costa Rica In Europe overall, B-cell precursor ALL has been increasing by around 1% each year. [89]
