Leukemia - Acute Lymphocytic - ALL: Statistics

Approved by the Cancer.Net Editorial Board, 05/2017

ON THIS PAGE: You will find information about the number of people who are diagnosed with ALL each year. You will also read general information on surviving the disease. Remember, survival rates depend on several factors. Use the menu to see other pages.

This year, an estimated 5,970 people of all ages (3,350 men and boys and 2,620 women and girls) in the United States will be diagnosed with ALL.

A person of any age can be diagnosed with ALL. ALL is most common before age 20, accounting for 75% of all leukemia diagnosed before that age. It is more common in children younger than 5. After a child grows into adulthood, the general risk of ALL rises again after age 50. About 4 out of every 10 people diagnosed with ALL are adults.

Although most cases of ALL occur in children, about 4 out of 5 deaths from ALL will occur in adults. An estimated 1,440 deaths (800 men and boys and 640 women and girls) will occur this year.

Advances in treatment have dramatically lengthened the lives of people with ALL. The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. The 5-year survival rate of people of all ages with ALL increased from 41% for those diagnosed from 1975 to 1977 to 71% for those diagnosed from 2006 to 2012. However, survival rates depend on several factors, including biologic features of the disease and a person’s age.

It is important to remember that statistics on the survival rates for people with ALL are an estimate. The estimate comes from annual data based on the number of people with this cancer in the United States. People should talk with their doctor if they have questions about this information. Also, experts measure the survival statistics every 5 years. So the estimate may not show the results of better diagnosis or treatment available for less than 5 years.
