Leukemia - Acute Lymphocytic - ALL: Statistics

Approved by the Cancer.Net Editorial Board, 11/2014

ON THIS PAGE: You will find information about how many people are diagnosed with this type of leukemia each year and some general survival information. Remember, survival rates depend on several factors. To see other pages, use the menu on the side of the screen.

This year, an estimated 6,250 people of all ages (3,100 men and boys and 3,150 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 76% of all leukemia diagnosed before that age. It is especially common in children younger than 5. After a child grows into adulthood, the general risk of ALL rises again after age 50. About four out of every ten ALL diagnoses will be adults.

Although most cases of ALL occur in children, about four out of five deaths from ALL will occur in adults. An estimated 1,450 deaths (800 men and boys and 650 women and girls) will occur this year.

It is important to note that advances in treatment have dramatically lengthened the lives of people with ALL. The five-year survival rate is the percentage of people who survive at least five years after the cancer is found. The five-year survival rate of people of all ages with ALL increased from 41% for those diagnosed from 1975-1977 to 70% for those diagnosed from 2004 to 2010. It is important to note that how long a person with ALL lives depends on several factors, including biologic features of the disease and a person’s age.

Cancer survival statistics should be interpreted with caution. These estimates are based on data from thousands of people with this type of cancer in the United States each year, so the actual risk for a particular individual may be different. It is not possible to tell a person how long he or she will live with ALL. Because the survival statistics are measured in five-year intervals, they may not represent more recent advances made in the treatment or diagnosis of this cancer.
