Abstract:
Objective To investigate the significance of plasma D-dimers,high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol (LDL-C) and apolipoprotein a (LP (a)) of patients with gastrointestinal cancer.Methods One hundred and thirty-nine cases with gastrointestinal cancer and 155 healthy persons were selected as subjects.Latex enhanced immunoassays method was used to measure the D dimer concentration.Direct method was applied to detect the levels of serum HDL-C,LDL-C,LP (a)Chemiluminescence method was applied to detect serum carcinoembryonic antigen (CEA)concentration.Determine the sensitivity and specificity of each index in gastrointestinal cancer,and explore the relationship between the concentration and the lymph node metastasis and distant metastasis.Results The levels of D-dimer,LDL-C,LP (a),CEA in patients with gastrointestinal carcinoma were 0.80 (2.37) mg/L,3.46 (1.46) mmol/L,317 (262) mg/L,2.61 (3.62) μ,g/L respectively,significant higher than those of health control(0.21 (0.22) mg/L,2.86 (0.98) mtmol/L,139 (187) g/L,1.29 (1.42) μg/L respectively; Z =-8.388,-6.150,-8.589,-7.142,P ＜0.001).The level of HDL-C in gastrointestinal cancer patients was 0.86(0.38) mmoL/L,lower than that of health control(1.29(1.42) mmol/L; Z =-10.643,P ＜0.001)The area of ROC curve of D-dimmer,HDL-C,LDL-C,LP (a),CEA were 0.783,0.859,0.708,0.790,0.741 respectively.Compared with area of ROC curve of CEA,that of D-dimer,LDL-C,LP(a) were significant different (Z =1.110,0.809,1.257 ; P =0.27,0.42,0.21).Compared with CEA AUC,HDL-C AUC was significant different (Z =3.225,P =0.0013).Compared with patients with no lymph node metastasis,the levels of D-dimers,LDL-C,LP (a) in patients with lymph node metastasis were higher (P =0.003,0.002,0.005 respectively).And the concentration of HDL-C decreased significantly (P =0.001).Compared with patients without metastases,serum D-dimer,LDL-CLP (a) concentration in patients with distant metastasis were significant higher(P ＜ 0.001) and the concentration of HDL-C decreased (P ＜ 0.001).Conclusion The levels of D-dimer and lipoprotein might be proved the base for diagnosis or assessment of gastrointestinal malignant tumor.
