ABSTRACT
Objective To investigate the clinical value of KL-6 mucin in differential diagnosis of benign and malignant obstructive jaundice.Methods A total of 41 patients with malignant tumors and 15 with benign lesions were recruited in the study.KL-6 mucin levels of bile and serum were measured using enzyme-linked immunosorbent assay (ELISA).The serum alpha-fetoprotein (AFP),carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 levels were also measured using radioimmunoassay (RIA).All data were analyzed by Mann-Whitney U test and Receiver Operating Characteristics (ROC)curves.Results CEA,CA19-9,and KL-6 mucin in serum and KL-6 mucin in bile in patients with malignant tumors were significantly higher than those in patients with benign lesions (P < 0.001).There were no significant differences in serum AFP between the two groups.An receiver operating characteristic (ROC)curves analysis revealed that the detection of KL-6 mucin in bile was reasonably accurate in differentiating malignant obstructive jaundice from benign (area under curve [AUC] 0.954).While the AUC of the ROC curves for serum AFP,CEA,CA19-9,KL-6 mucin and KL-6 in bile and 0.954 were 0.657,0.753,0.894,0.846 and 0.954 respectively.Using the ideal threshold as the cut-off point,the sensitivity and specificity of KL-6 mucin for differential diagnosis of benign and malignant obstructive jaundice was 90.24%and 93.33%.Conclusion As a tumor marker,KL-6 mucin in bile is valuable in differential diagnosis of benign and malignant obstructive jaundice.
