Abstract:
Objective To investigate the expression and significance of serum thymidine kinase-1(TK1), soluble intercellular adhesion molecule-1(sICAM-1),miR-210,and carcinoembryonic antigen(CEA)in pa-tients with colorectal cancer.Methods A total of 200 patients with colorectal cancer treated in the hospital from 2015 to 2017 were enrolled as the observation group and 50 healthy subjects were enrolled as the control group.Serum levels of TK1,sICAM-1,miR-210,and CEA were measured before and after treatment,and the trend of each indicator was analyzed.To analyze the relationship between tumor site,degree of tumor differen-tiation,clinical stage,w hether it is the first patient,lymph node metastasis and miR-210 levels in patients with colorectal cancer.Results The concentrations of sICAM-1,CEA,sTK1 and miR-210 in the observation group were significantly higher than those in the control group(P<0.05).The expression of miR-210 was related to the clinical stage and lymph node metastasis(P<0.05).T he sensitivity,specificity,positive predictive value, negative predictive value and accuracy of the combined tests including serum TK 1,sICAM-1,miR-210 and CEA test were higher than those of the single test,and was also higher than the combined tests of TK1,miR-210 and CEA.The sensitivity of the four combined tests was 75.70%,the specificity was 86.00%,the positive predictive value was 82.00%,the negative predictive value was 88.00%,the accuracy was 92.40%.Conclusion The combined detection of serum TK1,sICAM-1,miR-210 and CEA may have some value in the early diag-nosis of colorectal cancer,and can improve the sensitivity and specificity of colorectal cancer diagnosis.
