Importance: Advances in cancer research and treatment access have led to decreasing cancer mortality in the US; however, cancer remains the leading cause of death among Hispanic individuals.
Objective: To evaluate longitudinal cancer mortality trends from 1999 to 2020 among Hispanic individuals by demographic characteristics and to compare age-adjusted cancer death rates between the Hispanic population and other racial and ethnic populations during 2000, 2010, and 2020.
Design, setting, and participants: This cross-sectional study obtained age-adjusted cancer death rates among Hispanic individuals of all ages between January 1999 and December 2020, using the Centers for Disease Control and Prevention WONDER database. Cancer death rates in other racial and ethnic populations were extracted for 2000, 2010, and 2020. Data were analyzed from October 2021 to December 2022.
Exposures: Age, gender, race, ethnicity, cancer type, and US census region.
Main outcomes and measures: Trends and average annual percent changes (AAPCs) in age-adjusted cancer-specific mortality (CSM) rates among Hispanic individuals were estimated by cancer type, age, gender, and region.
Results: From 1999 to 2020, 12 644 869 patients died of cancer in the US, of whom 690 677 (5.5%) were Hispanic; 58 783 (0.5%) were non-Hispanic American Indian or Alaska Native; 305 386 (2.4%), non-Hispanic Asian or Pacific Islander; 1 439 259 (11.4%), non-Hispanic Black or African American; and 10 124 361 (80.1%), non-Hispanic White. For 26 403 patients (0.2%), no ethnicity was stated. The overall CSM rate among Hispanic individuals decreased by 1.3% (95% CI, 1.2%-1.3%) annually. Overall CSM rate decreased more for Hispanic men (AAPC, -1.6%; 95% CI, -1.7% to -1.5%) compared with women (AAPC, -1.0%; 95% CI, -1.0% to -0.9%). While death rates among Hispanic individuals decreased for most cancer types, mortality rates for liver cancer (AAPC, 1.0%; 95% CI, 0.6%-1.4%) increased among Hispanic men, and rates of liver (AAPC, 1.0%; 95% CI, 0.8%-1.3%), pancreas (AAPC, 0.2%; 95% CI, 0.1%-0.4%), and uterine (AAPC, 1.6%; 95% CI, 1.0%-2.3%) cancers increased among Hispanic women. Overall CSM rates increased for Hispanic men aged 25 to 34 years (AAPC, 0.7%; 95% CI, 0.3%-1.1%). By US region, liver cancer mortality rates increased significantly in the West for both Hispanic men (AAPC, 1.6%; 95% CI, 0.9%-2.2%) and Hispanic women (AAPC, 1.5%; 95% CI, 1.1%-1.9%). There were differential findings in mortality rates when comparing Hispanic individuals with individuals belonging to other racial and ethnic populations.
Conclusions and relevance: In this cross-sectional study, despite overall CSM decreasing over 2 decades among Hispanic individuals, disaggregation of data demonstrated that rates of liver cancer deaths among Hispanic men and women and pancreas and uterine cancer deaths among Hispanic women increased from 1999 to 2020. There were also disparities in CSM rates among age groups and US regions. The findings suggest that sustainable solutions need to be implemented to reverse these trends among Hispanic populations.
