title: Risk factors for venous thromboembolism in cancer: novel findings from the Vienna Cancer and Thrombosis Study (CATS).
abstract: Venous thromboembolism (VTE) occurs frequently in patients with cancer and contributes to elevated morbidity and mortality. Risk factors for the occurrence of VTE events in patients with cancer have been investigated in numerous clinical studies. For now more than 10 years, the Vienna Cancer and Thrombosis Study (CATS) has focused on the identification of parameters predictive of future VTE occurrence. CATS has contributed to new findings, which may help identify patients at high risk of developing VTE, by means of biomarkers (such as D-dimer, prothrombin fragment 1+2, soluble P-selectin, platelet count, coagulation factor VIII activity, thrombin generation potential, etc.). The association of tissue factor bearing microparticles and the mean platelet volume with the risk of VTE was also elaborately investigated in the framework of CATS. More recently CATS has researched clinical and clinicopathologic parameters which contribute to identification of patients at risk of VTE. The type of cancer is one of the most important risk factor for VTE occurrence. Also the stage of cancer and the histological grade of a tumor have been found to be associated with the occurrence of cancer-related VTE. In further investigations, venous diseases including a history of previous VTE, a history of superficial thrombophlebitis and the presence of varicose veins, have been associated with the risk of VTE in CATS.
