Abstract 6114: Trends in hematological cancer subtype mortality by educational attainment and sex in the United States, 2000-2020

Abstract

Abstract Objective: To examine mortality trends for hematological cancer subtypes (leukemia, Hodgkin’s lymphoma, non-Hodgkin’s lymphoma, and myeloma) by educational attainment and sex in the United States. Methods: Using data on 1,082,234 U.S. deaths from 2000-2020, age-standardized death rates were calculated by sex and educational attainment (high school/GED or less, some college, and 4 years of college or more). Annual percentage change (APC) and 95% confidence intervals (CI) for mortality rates were generated using Joinpoint regression. Results: For all hematological cancer subtypes, mortality rates were largest among males and those with the least education for all study years. In general, decreasing trends were observed in recent years for non-Hodgkin’s lymphoma, myeloma, and leukemia mortality rates. Non-Hodgkin’s lymphoma mortality rates, for example, decreased among males and females in 2009-2020 (APC: -2.0%; 95%CI: -2.4%, -1.5% and APC: -2.8%; 95%CI -3.2%, -2.3%). As another example, non-Hodgkin’s lymphoma mortality rates among most educated males decreased in 2000-2012 (APC: -1.8%; 95%CI: -2.2%, -1.3%) followed by a steeper decline in 2012-2020 (APC: -3.7%; 95%CI: -4.4%, -2.9%); a similar pattern was observed among most educated females (APC: -1.6%; 95%CI: -2.2%, -1.0% in 2000-2011 and APC: -4.1%; 95%CI: -4.9%, -3.4% in 2011-2020). Trends in Hodgkin’s lymphoma death rates however differed by educational attainment. For example, mortality rates among least educated males increased in 2000-2009 (APC: 1.7%; 95%CI: 0.8%, 2.5%) and remained unchanged in 2009-2020 (APC: -0.3%; 95%CI: -0.9%, 0.3%). Rates among least educated females also increased in 2000-2020 (APC: 0.4%; 95%CI: 0.1%, 0.7%). In contrast, mortality rates declined for most educated males from 2010-2020 (APC: -1.9%; 95%CI: -2.6%, -1.2%) and most educated females from 2011-2020 (APC: -3.5%; 95%CI: -4.8%, -2.2%). Conclusion: Hematological cancer mortality rates were highest among males and those with least education. In general, mortality rates have declined in recent years for non-Hodgkin’s lymphoma, myeloma, and leukemia for males and females among all educational attainment groups, while Hodgkin’s lymphoma has shown a slight increasing trend among least educated males and females.
