Abstract:

Objective To investigate the relationships of plasma thrombomodulin(TM),thrombin-antithrombin complex(TAT),plasmin-alpha 2 plasmin inhibitor complex(PIC) and tissue plasminogen activator-plasminogen activator inhibitor-1 complex(t-PAI-C) with tumors.Methods The levels of plasma TM,TAT,PIC and t-PAI-C were determined by chemiluminescence enzyme immunoassay in 164 malignant tumor patients(81 cases of respiratory tract cancer and 83 cases of gastrointestinal cancer) and 52 healthy subjects(healthy control group). The difference of plasma TM,TAT,PIC and t-PAI-C between malignant tumor and healthy control groups was evaluated,and the difference between tumor metastasis and non-tumor metastasis groups was analyzed as well.Results The levels of TM,TAT,PIC and t-PAI-C in malignant tumor group were higher than those in healthy control group(P<0.01). The levels of TM,TAT and PIC in respiratory tract cancer group were higher than those in healthy control group(P<0.01),and there was no statistical significance for t-PAI-C between the 2 groups(P>0.05). There was statistical significance for TM,TAT,PIC and t-PAI-C between gastrointestinal cancer group and healthy control group(P<0.01). In malignant tumor group,TAT,PIC and t-PAI-C were higher in tumor metastasis group than those in non-tumor metastasis group(P<0.01),while TM had no statistical significance between the 2 groups(P>0.05). In respiratory tract cancer and gastrointestinal cancer groups,the levels of TAT,PIC and t-PAI-C in tumor metastasis group were higher than those in non-tumor metastasis group(P<0.01),while there was no statistical significance for TM(P>0.05).Conclusions Malignant tumor patients have different degrees of vascular endothelial injury and coagulation-fibrinolytic system disorder. Plasma TM,TAT,PIC and t-PAI-C can be used as indicators for malignant tumor progression,curative effect and prognosis.
