ABSTRACT
This overview of the coagulation biology of cancer is intended primarily for those
unfamiliar with the link between the coagulation mechanism and neoplasia. Because
the literature on this topic is extensive, citations will be primarily of previous
reviews that provide detailed references. The clotting mechanism is fundamentally
deranged in malignancy and, unlike the physiological hemostatic response to injury,
is incapable of self-attenuation. Clotting activation may predict future cancer and
the outcome of existing cancer, and participates in tumor growth. Anticoagulant therapy
in patients with malignancy achieves more than control of cancer-related thrombosis.
Modification of coagulation reactions relevant to particular tumor types improves
the course of the disease. Viewing malignancy as a solid-phase coagulopathy provides
insights into possible "upstream" causes of malignant transformation and explanations
for the aberrant behavior of transformed cells and suggests innovative experimental
interventions. Coagulation biology has broadened and deepened our understanding of
neoplasia, and suggested testable strategies for the prevention and treatment of cancer.
However, relationships between clotting and cancer progression have been established
primarily from model systems. Although limited experience to date in human disease
has supported these concepts, resolution of cause-and-effect relationships will require
performance of additional rationally designed clinical trials.
