Abstract:
Objective:The aim of this study is to investigate the variation tendency of coagulation and fibrinolysis biomarkers in cancer patients and to explore the effect of these biomarkers for the diagnosis of thrombosis in cancer patients.
Methods:171 cancer patients admitted to hospital from September 2017 to July 2019 were enrolled in the study, including 40 cancer patients undergoing surgery, 108 cancer patients without surgery in control group and 23 cancer patients with thrombus. New coagulation and fibrinolysis biomarkers, TM (Thrombomodulin), TAT (Thrombin -antithrombin complex), PIC (Plasmin alpha 2-plasmin inhibitor complex) and t-PAI·C (Tissue plasminogen activator-plasminogen activator inhibitor-1 complex), were tested in every patient. In addition, these new biomarkers are compared with D-dimer.
Results:A statistically difference was available on the value of TAT, TM, PIC, t-PAIC, between postoperative cancer patients group and control group (P<0.05, respectively). TAT, TM and PIC in thrombosis cancer group were higher than those in non-thrombosis cancer group (P<0.05; respectively). ROC was used to evaluate the performance of D-dimer, TAT and PIC on thrombosis in cancer patients. The results showed that the AUC of PIC and TAT were both higher than D-dimer (0.871 vs. 0.619; 0.788 vs. 0.619). The specificity of PIC alone was higher than that of D-dimer (91.9% vs. 82.4%), and the sensitivity of PIC and TAT alone was higher than that of D-dimer (73.9% vs. 47.8%, 73.9% vs. 47.8%, respectively).
Conclusions:The activity of coagulation and fibrinolysis in cancer patients was abnormally enhanced. TAT and PIC were better than D-dimer for the diagnosis of thrombosis in cancer patients.
