目的:探讨肿瘤标志物 CA19- 9、CA2 4 2 和 CEA对胰腺癌联合检测的意义。 方法:用酶联免疫吸附(EL ISA)法对 34例胰腺癌病人进行血清学肿瘤标志物检测。 结果:3种肿瘤标志物中敏感性和特异性以 CA19- 9最好 ,分别为 79.4 %和 85 .0 % ,联合检测这 3种肿瘤标志物可使敏感性提高到 88.2 % ;综合考虑敏感性和特异性 ,以 CA19- 9联合 CA2 4 2 检测效果最佳。 结论 :CA19- 9可以作为有价值的胰腺癌诊断指标 ,联合检测肿瘤标志物有助于胰腺癌的诊断。
Objective: To investigate the significance of the detection of tumor markers CA19-9, CA2 4 2 and CEA in pancreatic cancer. Methods: Serum tumor markers were detected in 34 patients with pancreatic cancer by enzyme-linked immunosorbent assay (ELISA). Results: The sensitivity and specificity of the three kinds of tumor markers were the best of CA19-9, 79.4% and 85.0% respectively. The joint detection of these three tumor markers could increase the sensitivity to 88.2%. Considering the sensitivity Sex and specificity, with CA19-9 combined with CA2 4 2 detection best. Conclusion: CA19-9 can be used as a valuable diagnostic indicator of pancreatic cancer. Combined detection of tumor markers is helpful for the diagnosis of pancreatic cancer.
