Cancer-Related Coagulopathy and Perioperative Considerations.

Cancer-related coagulation abnormalities are characterized by complex dysregulation of the hemostatic system, predisposing patients to increased risk of thrombotic and hemorrhagic complications and associated increased morbidity and mortality. Advances in anticancer therapies with improved outcomes have led to better survival and older age of patients living with or having survived cancer. There is also a significant increase in the number of patients diagnosed with cancer. All these factors will increase the number of patients presenting for surgical procedures, both cancer-related and noncancer related. It is important for the anesthesiologist to understand the magnitude of cancer-related coagulation derangement, its types, pathophysiology, and clinical presentation, to optimize the perioperative management of this high-risk rapidly growing patient population.
