Idiopathic venous thrombosis (VTE) is frequently associated with underlying malignancy. Thus, it is tempting to search for underlying cancer in these patients. However, extensive screening is
cost-intensive and no survival benefit has been demonstrated. Based on a review of the literature, we recommend the performance of a thorough medical history and physical examination in
addition to basic biochemical screening and a chest X-ray in patients with idiopathic VTE. Only specific symptoms or findings should lead to a more extensive work-up.
