These mechanisms include activation of the coagulation and fibrinolytic systems. Tumor cells activate coagulation by expressing procoagulant molecules, releasing pro-inflammatory and pro-angiogenic cytokines, and adhering to vascular and blood cells. Tumor-secreted and tissue factor-positive extracellular vesicles are another major driver of CAT, while emerging studies have discovered a role for podoplanin (PDPN) in intratumoral thrombosis, hyper-coagulation, and enhanced VTE risk.
