DefinitionChronic lymphocytic leukemia (CLL) incidence refers to the number of persons newly diagnosed with CLL within a specified time period. Measures include 1) the number of newly diagnosed CLL cases; and 2) age-adjusted CLL incidence rates (adjusted by the direct method to the 2000 US standard population). Rates are expressed per 100,000 persons.
NumeratorThe number of CLL cases newly diagnosed in New Mexico residents within a specified time period. The data are based on the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program incidence site recodes for CLL: 35012 (chronic lymphocytic leukemia). http://seer.cancer.gov/siterecode/
DenominatorThe estimated population of New Mexico residents within a specified time period.
Why Is This Important?Leukemia is a cancer of the blood-forming cells that affects both adults and children. Leukemia is the most common form of cancer diagnosed in children and adolescents, and often arises very rapidly over a short period (acute form). Chronic lymphocytic leukemia is more common among adults, and causes the bone marrow to make too many lymphocytes (a type of white blood cell).
Chronic lymphocytic leukemia and 15% of all leukemias in adults. Each year, chronic lymphocytic leukemia accounts for just over 1% of all new cancer cases and less than 1% of all cancer deaths in the U.S. This equates to 8,220 cases and 1,070 deaths annually. The five-year survival rate is 83.2%.
New Mexico has averaged 113 new cases of chronic lymphocytic leukemia each year between 2010 and 2015. Rates have remained relatively stable in New Mexico over time, which is consistent with national trends.
The causes of leukemia are not well understood, but appear to involve a combination of hereditary and environmental factors.
