Solid tumors can provoke a hypercoagulable state through the release of pro-coagulant factors, endothelial activation, and inflammation, leading to a heightened risk of coagulation disorders.

These disorders can complicate surgical interventions and impact treatments, including chemotherapy and immunotherapy efficacy, leading to poor outcomes. Understanding the implications of coagulation disorders in solid tumors is essential for optimizing patient management, including identifying high-risk patients, implementing prophylactic measures, elucidating biomarkers for clinical outcomes, and exploring novel therapeutic agents.
