Abstract: Coagulation activation is associated with cancer progression and morbidity. Recently, mechanisms
through which coagulation proteases drive the tumor microenvironment (TME) have been elucidated. This review
aims to develop a new strategy dependent on the coagulation system for treating osteosarcoma (OS). We
focused on tissue factor (TF), the main initiator of the extrinsic coagulant pathway, as a target for OS treatment.
It was found that cell surface-TF, TF-positive extracellular vesicles, and TF-positive circulating tumor cells
could drive progression, metastasis, and TME in carcinomas, including OS. Thus, targeting tumor-associated
coagulation by focusing on TF, the principle catalyst of the extrinsic pathway, TF is a promising target for OS.
