Thromb Haemostasis
-
We have previously demonstrated that patients with idiopathic venous thromboembolism (VTE) have a higher frequency of underlying cancer. Now we present a retrospective analysis of our 5-year experience with a series of 674 consecutive otherwise healthy patients, and a more restricted battery of diagnostic tests. Occult cancer was found in 15 patients during admission. ⋯ At variance with VTE patients and previously known cancer, most patients with occult malignancy were at an early stage. Further studies are needed to confirm whether patients with idiopathic VTE could benefit from screening for occult cancer. Meanwhile, our findings may serve as guidelines for physicians in this field.
