Objective To explore the clinical significance of plasma biomarkers of prethrombotic state in lung cancer patients. Methods 90 patients with lung cancer (lung cancer group) and 90 normal controls (control group) of Han population in Shanghai Pulmonary Hospital from June 2010 to June 2012 were recruited in the study. Enzyme-linked immunosorbent assay (ELISA) was used to detect the plasma levels of von willebrand factor(vWF),P-selectin,and thrombin-antithrombine complex (TAT). Coagulation indicators were detected by ACLTOP full automatic coagulation analyzer. Solidification method was used to detect the plasma levels of prothrombin time (PT),activated partial thromboplastin time (APTT) and fibrinogen (FIB). Turbidimetric immunoassay was used to detect D-dimer concentration,and chemiluminescence substrate was used to assay antithrombin Ⅲ (AT-Ⅲ). Results In the lung cancer group,the plasma levels of vWF,P-selectin,TAT,D-dimer and FIB were significantly higher than those in the control group (P<0.05),and the plasma levels of APTT and AT-Ⅲ were lower than those in the control group(P<0.05),while there was no significant difference in plasma PT level(P>0.05). In stage Ⅳ lung cancer subgroup,the plasma levels of vWF,P-selectin,TAT,D-dimer and FIB were significantly higher than those in the stage Ⅲ subgroup or the stage Ⅰ+Ⅱ subgroup (P<0.05). And the plasma levels of PT and APTT were significantly lower than those in the stage Ⅲ subgroup or the stage Ⅰ+Ⅱ subgroup (P<0.05). Conclusion The patients with lung cancer exist obvious prethrombotic state. AT-Ⅲ,vWF, D-dimer, FIB,TAT,P-selectin and APTT can be used as reliable hematol markers in early diagnosis of prethrombotic state. vWF,P-selectin,TAT and D-dimer have higher sensitivity and specificity.
