ABSTRACT
Objective To evaluate the diagnostic value of the level of plasma D-dimer, lipoproteins and carcino-embry-onic antigen(CEA) in gastrointestinal cancer.Methods The plasma D-dimer ,lipoproteins,CEA and clinicopathological data of 139 gastrointestinal cancer patients and 155 normal controls were collected and analyzed .Lipoproteins included high-density lipoprotein(HDL),low-density lipoprotein(LDL) and lipoprotein a[LP(a)].SPSS 13.0 statistical software was used to analyze the sensitivity and specificity of each examination method and to find the appropriate combination .Results The plasma D-dimer,LDL,LP( a) and CEA levels were distinctly higher in patients than those in normal controls ( P<0.001).HDL levels were significantly lower in patients than those in normal controls (P<0.001).The cutoff of D-dimer was 0.495 μg/ml , the sensitivity of D-dimer was 62.6%,and the specificity was 86.5%.The cutoff of HDL was 1.025 mmol/L, the sensitivity was 72.7%,and the specificity was 85.2%.The cutoff of LDL was 3.375 mmol/L, the sensitivity was 54%,and the specificity was 82.6%.The cutoff of LP(a) was 27.3 mg/dl, the sensitivity was 58.3%,and the speci-ficity was 87.1%.The cutoff of CEA was 2.14 ng/ml, the sensitivity was 59.7%,and the specificity was 76.8%.The sensitivity and specificity of HDL +CEA were 77.7%and 88.4%, respectively.The sensitivity and specificity of HDL +D-dimer were 70.5% and 96.1%, respectively.The sensitivity of HDL +LP(a) was 76.3%,and the specificity was 93.5%.The sensitivity of D-dimer +HDL+LP(a) was 84.2%,and the specificity was 92.3%.The sensitivity of D-dimer +HDL+CEA was 87.1%, and the specificity was 85.8%.The sensitivity and specificity of HDL +LP(a) +CEA were 85.6%and 92.3%, respectively.The sensitivity of D-dimer +HDL+CEA +LP(a) was 89.9%while the specificity was 92.3%.Conclusions Plasma D-dimer and lipoproteins can serve as tumor markers in gastrointestinal cancer .Combined detection has higher sensitivity and specificity .
