Incidence of Chronic Lymphocytic Leukemia by County, New Mexico, 2017-2021

  • #This count or rate is statistically unstable (RSE >0.30), and may fluctuate widely across time periods due to random variation (chance). Please use caution in interpreting this value, or combine years, areas, or age groups to increase the population size.
  • ##The estimate has a relative standard error greater than 50% and does not meet standards for reliability. A count or rate such as this should not be used to inform decisions. Try combining years, areas, or age groups to increase the population size.

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.

Data Notes

Rates have been age-adjusted using the direct method and the 2000 U.S. standard population.

Data Sources

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.

Data Issues

  • New Mexico Population Estimates

    All population estimates apply to July 1 of the selected year. These estimates are considered the most accurate estimates for the state of New Mexico and should match those found on the University of New Mexico Geospatial and Population Studies website. Estimates include decimal fractions. Census tract population estimates were summed to produce County and Small Area population estimates. Population estimate totals may vary due to rounding. Population estimates for previous years are occasionally revised as new information becomes available. When publishing trend data, always be sure that your rates for earlier years match current rates on NM-IBIS that have been calculated with the most up-to-date population estimates.

  • New Mexico Tumor Registry

    In agreement with the New Mexico Tumor Registry, to ensure confidentiality the count of cancer cases is suppressed for any given county if the count is between one and four and the population is less than 1,000. NOTE: The COVID-19 pandemic disrupted health services, leading to delays and reductions in cancer screening, diagnosis, and reporting to some central cancer registries. This may have contributed to an observed decline in 2020 incidence for most cancer sites.
