Overview
In the United States, the age-adjusted prevalence of ALL is 17.4 per 100,000 in 2011.[1] There is an increased incidence in people with Down's Syndrome, Fanconi's anemia, Bloom's syndrome, ataxia-telangiectasia, X-linked agammaglobulinemia and severe combined immunodeficiency. ALL accounts for approximately 80 percent of all childhood leukemia cases, making it the most common type of childhood cancer.
Epidemiology and Demographics
Prevalence
- In the United States, the age-adjusted prevalence of ALL is 17.4 per 100,000 in 2011.[1]
Incidence
- The number of annual ALL cases in the US is roughly 4000, 3000 of which inflict children.
- There is an increased incidence in people with Down's Syndrome, Fanconi's anemia, Bloom's syndrome, ataxia-telangiectasia, X-linked agammaglobulinemia and severe combined immunodeficiency.
- In 2011, the age-adjusted incidence of ALL was 1.77 per 100,000 persons in the United States.[1]
Age
- ALL accounts for approximately 80 percent of all childhood leukemia cases, making it the most common type of childhood cancer.
- It has a peak incident rate of 2-5 years old, decreasing in incidence with increasing age before increasing again at around 50 years old.
- While the overall age-adjusted incidence of ALL in the United States between 2007 and 2011 is 1.7 per 100,000, the age-adjusted incidence of ALL by age category is:[1]
- Under 65 years: 1.7 per 100,000
- 65 and over: 1.6 per 100,000
Gender
- ALL is slightly more common in males than females.
- In the United States, the age-adjusted prevalence of ALL by gender in 2011 is:[1]
- In males: 19.3 per 100,000
- In females: 15.4 per 100,000
- In the United States, the age-adjusted incidence of ALL by gender on 2011 is:[1]
- In males: 1.9 per 100,000 persons
- In females: 1.63 per 100,000 persons
- Shown below is an image depicting the observed incidence of lymphocytic leukemia by gender in the United States between 1975 and 2011. These graphs are adapted from SEER: The Surveillance, Epidemiology, and End Results Program of the National Cancer Institute.[1]
Race
- Shown below is a table depicting the age-adjusted prevalence of ALL by race in 2011 in the United States.[1]
| All Races | White | Black | Asian/Pacific Islander | Hispanic | |
| Age-adjusted prevalence | 17.4 per 100,000 | 20 per 100,000 | 7.6 per 100,000 | 13.2 per 100,000 | 20.8 per 100,000 |
