Purpose: The incidence of cancer-associated venous thromboembolism has increased, but whether short-term mortality after cancer-associated venous thromboembolism has changed remains uncertain. We investigated whether the increasing incidence of venous thromboembolism in cancer patients is associated with a change in mortality.Methods: We used administrative medical registries to identify a cohort of all Danish patients diagnosed with a first primary cancer from 2006 to 2017.
