Abstract:
Objective To detect the plasma level of tissue factor (TF) in non-small cell lung cancer (NSCLC) patients,and to discuss its association with hypercoagulation,venous thromboembolism and prognosis of lung cancer.Methods Sixty-one impatients in our hospital with confirmed lung cancer were enrolled as the study group.Thirteen patients with benign pulmonary diseases and 14 healthy volunteers were selected as the control groups.Bseline and follow-up clinical data were collected from participants.Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of TF in plasma of all subjects.Results The levels of TF in plasma from NSCLC patients and participants with benign pulmonary diseases was significantly higher than that in healthy controls((550.88 ± 201.58) ng/L vs (510.77 ± 201.20) ng/L vs (178.34 ±66.73) ng/L,P ＜0.05).According to the plasma levels of TF,which have been detected in all subjects,the patients were divided into two groups:low level group (range from 103.73 ng/L to 476.22 ng/L) and high level group (range from 476.221 ng/L to 1003.00 ng/L).Statistical analysis showed that there was a positive correlation between plasma TF levels and TNM stages in NSCLC patients (P =0.026).Patient with metastasis had a higher plasma TF level than other patients (P =0.020).The log-rank test revealed that there was no significant difference in survival between the high level group and low level group (x2 =0.145,P =0.704).Multivariate Cox proportional hazards regression analysis indicated that plasma TF levels did not predicted for death(RR =1.001,95％CI0.998-1.004,P=0.452).Conclusion The plasma TF level in NSCLC patients was correlated with TNM stages;it had no significant relationship with hypercoagulation state and survival rate in NSCLC patients.Limitations should be aware of while evaluating the clinical course and prediction of prognosis of NSCLC patients using plasma TF levels.
