The coagulation and fibrinolysis profile was evaluated in 40 patiens with newly diagnosed untreated colorectal carcinoma (24 males, 16 females; 29 patients without and 11 patients with metastases). Fibrinogen, von Willebrand factor antigen, FVIILC, thrombin-antithrombin III complex (TAT III), fibrin monomers (FM), plasminogen activator inhibitor-1 (PAI-1) and I-dimers were tested. None of the patients had clinical or laboratory evidence of serious hemorrhage or thrombosis. The results of global routine coagulation tests (aPTT, PT) were not significantly changed. Significant elevations were found for median fibrinogen, von Willebrand factor antigen, FVIILC, TAT III and D-dimers, compared with a healthy reference group. These results confirm earlier reports of an enhanced level of both coagulation and fibrinolysis markers in carcinoma patients and might be helpful in trying to understand the impact of several relatively new sensitive coagulation and fibrinolysis parameters in colorectal cancer. Moreover the position of the coagulation/fibrinolysis balance might be an explanation for the elevated incidence of thrombotic events in patiens with cancer.
