Abstract:
Objective To investigate the clinical value of combined detection of serum carcinoembryonic antigen (CEA),carbohydrate antigen 199 (CA199) and tumor type M2 pyruvate kinase (TuM2-PK) for the diagnosis of early colon cancer.Methods A total of 137 patients with colon cancer in the First Affiliated Hospital of Yunnan University of Traditional Chinese Medicine from February 2014 to November 2016 were selected as observation group,87 patients with benign colon disease were selected as control group,and 75 healthy subjects were selected as health group.The levels of serum CEA and CA199 were detected by electrochemiluminescence,and serum TuM2-PK level was determined by quantitative enzyme-linked immunosorbent assay.The diagnostic value of single and combined detection on early colon cancer were compared.Results The levels and positive expression rate of serum CEA,CA199 and TuM2-PK in the observation group were significantly higher than those in the control group and the health group(P ＜0.05).There was no significant difference in the levels and positive expression rate of serum CEA,CA 199,TuM2-PK between the control group and the health group (P ＜ 0.05).The sensitivity and Youden index of combined detection of CEA,CA199 and TuM2-PK were better than those of single or two indexes detection(P ＜0.05).The specificity of combined detection of CEA,CA199 and TuM2-PK was better than that of single detection and combined detection of CEA,CA199 (P ＜ 0.05).The combined detection of two or three indexes in CEA,CA199 and TuM2-PK had certain diagnostic value for colon cancer,the area under the receiver operating characteristic curve ≥0.70;and the area under the receiver operating characteristics curve of the combined detection of CEA,CA199 and TuM2-PK was the largest.Conclusion The combined detection of CEA,CA199 and TuM2-PK has the high diagnostic value for colon cancer.
