Cancer Incidence - Chronic Lymphocytic Leukemia

Incidence of Chronic Lymphocytic Leukemia by County, New Mexico, 2017-2021
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 of time (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 accounts for 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 20,160 cases and 4,410 deaths annually. The five-year survival rate is 88%. The causes of leukemia are not well understood, but appear to involve a combination of hereditary and environmental factors.
Definition
Chronic 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.

How the Measure is Calculated
| Numerator: | The 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/ |
| Denominator: | The estimated population of New Mexico residents within a specified time period. |
How Are We Doing?
New Mexico has averaged 110 new cases of chronic lymphocytic leukemia each year between 2016 and 2020.
How Do We Compare With the U.S.?
Rates have declined in New Mexico over time, which is consistent with national trends. Nationally, chronic lymphocytic leukemia is more common among men than women, particularly white men. In contrast, the Black population in New Mexico had the highest incidence with 6.2 cases per 100,000 population. Overall the incidence is lower in New Mexico than nationally (4.0 vs 4.7 per 100,000, respectively).
