Several studies have indicated an association between venous thromboembolism (VTE) and a subsequent diagnosis of cancer in Western countries. However, information is scant on subsequent cancer incidence after idiopathic VTE events in Asian people. Through a nationwide cohort study, we evaluated the cancer prevalence of VTE and new cancer incidence in patients after the first episode of idiopathic VTE. ⋯ Patients with symptomatic VTE without an identifiable risk factor have a 6.89% incidence of subsequent cancer diagnosis in Taiwan. An extensive screening for an occult cancer in an idiopathic VTE patient may be warranted.
