Abstract:

Objective To investigate the correlation of the activities of protein C(PC), antithrombin(AT) and coagulation factor Ⅷ(FⅧ) with the treatment of lung cancer with pulmonary embolism(PE). Methods A total of 98 patients with lung cancer and PE were enrolled as lung cancer with PE group. A total of 100 patients with lung cancer were enrolled as lung cancer group. Their sex and age were recorded, and lipoprotein(a)[Lp(a)], total cholesterol(TC), triglyceride (TG), C-reactive protein(CRP), thrombin time(TT), platelet (PLT) and fibrinogen(Fbg)in the 2 groups were determined, respectively. PC, AT, FⅧ and D-dimer were determined in lung cancer with PE group after 5-7 d of treatment. Logistic regression analysis was used to analyze the factors influencing coagulation-fibrinolysis after 5-7 d of treatment in lung cancer with PE group. The receiver operating characteristic(ROC) curve was used to analyze the diagnostic efficiency of these factors. Resutls Lp(a), TC, TG and TT in lung cancer with PE group were significantly higher than those in lung cancer group (P<0.05). The levels of PC, AT, FⅧ and D-dimer were significantly higher in lung cancer with PE group than those in lung cancer group (P<0.01).Logistic regression analysis and ROC curve analysis showed that PC, AT and FⅧ were influencing factors of coagulation-fibrinolysis after 5-7 d of treatment in lung cancer with PE group, and the areas under ROC curve were >0.90. Conclusions The influence of PC, AT and FⅧ on coagulation-fibrinolysis should be concerned in midterm treatment of lung cancer with PE, and their activities can be used to assess the therapeutic efficiency and treatment program in a given period.
