Non-Hispanic Black cancer patients had significantly higher cardiovascular mortality (HR 1.25; 95% CI 1.24-1.27) and all-cause mortality compared to non-Hispanic White patients.

Are there racial and ethnic disparities in all-cause and cardiovascular mortality among adult cancer patients in the U.S.?
Significant racial and ethnic disparities exist in all-cause and cardiovascular mortality among U.S. cancer patients, with Non-Hispanic Black patients facing the highest risks, highlighting the need for targeted cardio-oncology survivorship care.
Effect estimate: HR 1.25 (95% CI 1.24-1.27)
Background: With improved cancer survival, death from noncancer etiologies, especially cardiovascular disease (CVD) mortality, has come more into focus. Little is known about the racial and ethnic disparities in all-cause and CVD mortality among U.S. cancer patients. Objectives: This study sought to investigate racial and ethnic disparities in all-cause and CVD mortality among adults with cancer in the United States. Methods: Using the Surveillance, Epidemiology, and End Results (SEER) database from years 2000 to 2018, all-cause and CVD mortality among patients ≥18 years of age at the time of initial malignancy diagnosis were compared by race and ethnicity groups. The 10 most prevalent cancers were included. Cox regression models were used to estimate adjusted HRs for all-cause and CVD mortality using Fine and Gray's method for competing risks, as applicable. Results: Among a total of 3,674,511 participants included in our study, 1,644,067 (44.7%) died, with 231,386 (6.3%) deaths as a result of CVD. After adjusting for sociodemographic and clinical characteristics, non-Hispanic (NH) Black individuals had both higher all-cause (HR: 1.13; 95% CI: 1.13-1.14) and CVD (HR: 1.25; 95% CI: 1.24-1.27) mortality, whereas Hispanic and NH Asian/Pacific Islander had lower mortality than NH White patients. Racial and ethnic disparities were more prominent among patients 18 to 54 years of age and those with localized cancer. Conclusions: Significant racial and ethnic differences exist in both all-cause and CVD mortality among U.S. cancer patients. Our findings underscore the vital roles of accessible cardiovascular interventions and strategies to identify high-risk cancer populations who may benefit most from early and long-term survivorship care.
Zhu et al. (Wed,) conducted a cohort in Cancer (n=3,674,511). Non-Hispanic Black race/ethnicity vs. Non-Hispanic White race/ethnicity was evaluated on CVD mortality (HR 1.25, 95% CI 1.24-1.27). Non-Hispanic Black cancer patients had significantly higher cardiovascular mortality (HR 1.25; 95% CI 1.24-1.27) and all-cause mortality compared to non-Hispanic White patients.
