Cancer Screening in Patients with Idiopathic Venous Thromboembolism--a Position Paper of the German Society of Hematology and Oncology Working Group on Hemostasis.

Cancer can trigger thromboembolism. There is a 4-10% chance of finding an asymptomatic occult cancer in patients with idiopathic venous thromboembolism (VTE). Current guidelines recommend limited cancer screening with history, physical examination, and screening examinations according to age after idiopathic VTE. Recent studies found that a more extensive screening program, including endoscopy and computed tomography, may increase the cancer detection rate. The Hemostasis Working Group of the German Society of Hematology and Oncology recommends a more extensive screening program after idiopathic VTE.
