Abstract:
Objective To study the clinical diagnostic value of carcinoembryonic antigen (CEA) ,cytokeratin(CK)19-2G2 and EB virus capsid antigen Ig (EB-VCA-Ig) combined detection for nasopharyngeal carcinoma .Methods Serum CEA ,CK19-2G2 and EB-VCA-Ig of 82 patients with nasopharyngeal carcinoma (malignant group) ,65 patients with benign nasopharyngeal diseases (benign group) and 58 healthy people(control group) were detected .Chemiluminescence was employed to detect CEA and CK19-2G2 ,and enzyme-linked immunosorbent assay(ELISA) was used to assay EB-VCA-Ig .Results Serum CK19-2G2 and EB-VCA-Ig concen-trations of patients in malignant group were higher than those in the benign group and control group ,respectively (P<0 .05) .The sensitivity and specificity of individual CK 19-2G2 detection for nasopharyngeal carcinoma were 48 .78% ,and 83 .74% ,respectively , those of CEA and EB-VCA-Ig combined detection were 53 .44% and 86 .99% ,respectively ,and those of three indicators combined detection were 71 .95% and 80 .49% ,respectively .Three indicators combined detection significantly increased the positive detection rates in patients with early and advanced stages .Conclusion CEA ,CK19-2G2 and EB-VCA-Ig combined detection possesses impor-tant value for nasopharyngeal carcinoma diagnosis .
