Abstract

Risk factors for venous thromboembolism (VTE) in elderly patients with acute myeloid leukemia (AML) are not known by race. The aim of this study was to determine the association of VTE with known risk factors and the impact of VTE on mortality in elderly white, black and Asian patients with AML. The merged SEER-Medicare database (2000-2015) was used for patients aged at least 65 years diagnosed with AML. Multivariable logistic regression was used to examine the association of VTE with known risk factors and Cox proportional hazards regression was used to evaluate the association of VTE with mortality in white, black and Asian patients. Among 21 403 AML patients aged at least 65years, VTE was diagnosed in 10.6% of 18 731 white patients, 13.4% of 1362 black and 5.6% of 1310 Asian patients. Overall, the adjusted risk of VTE in black patients was similar to white patients, but Asian patients had a lower risk of VTE. Risk factors for VTE in white patients were age less than 75 years, female sex, chemotherapy and comorbid medical conditions, including hypertension, anemia, chronic kidney and lung disease, hyperlipidemia, heart failure and obesity. In black patients, hyperlipidemia, and heart failure and in Asian patients, age less than 75 years, female sex, chemotherapy and hypertension and myocardial infarction were associated with VTE. Central venous catheter placement was a predictor of VTE in all three races. Our study identified risk factors for VTE by race in elderly white, black and Asian AML patients.
