D-Dimer and Prothrombin Fragment 1 + 2 Predict Venous Thromboembolism in Patients With Cancer: Results From the Vienna Cancer and Thrombosis Study
2009
Purpose Venous thromboembolism (VTE) is a well-recognized complication of cancer. Laboratory parameters might be useful to assess the VTE risk in patients with cancer. The aim of this study was to investigate D-dimer and prothrombin fragment 1 + 2 (F 1 + 2), which reflect activation of blood coagulation and fibrinolysis, for prediction of cancer-associated VTE. Patients and Methods In a prospective, observational, cohort study of 821 patients with newly diagnosed cancer or progression of disease who did not recently receive chemotherapy, radiotherapy, or surgery were enrolled and followed for a median of 501 days (interquartile range, 255 to 731 days). The malignancies in these patients were as follows: breast (n = 132), lung (n = 119), stomach (n = 35), lower gastrointestinal tract (n = 106), pancreas (n = 46), kidney (n = 22), and prostate (n = 101) cancers; high-grade glioma (n = 102); malignant lymphoma (n = 94); multiple myeloma (n = 17); and other tumor types (n = 47). The study end point was occurr...
