摘要: 目的 探讨血清Dickkopf-1(DKK1)和EB病毒壳抗体(VCA-IgA)联合检测在鼻咽癌中的诊断价值。方法 应用酶联免疫吸附试验检测80例鼻咽癌患者和65例正常对照者血清DKK1和VCA-IgA的水平,采用受试者工作特征(ROC)曲线评价诊断效能。结果 鼻咽癌患者血清DKK1的表达水平明显高于正常对照组[580.773(429.146)pg/ml∶316.174(252.965)pg/ml],差异有统计学意义(Z=4.846,P<0.000 1)。ROC曲线显示血清DKK1对鼻咽癌的最佳诊断临界值为611.981 pg/ml,其诊断曲线下面积(AUC)为0.734(95%CI为0.654~0.815),敏感性为50.0%,特异性为96.9%。VCA-IgA对鼻咽癌的诊断AUC为0.714(95%CI为0.631~0.798),敏感性为47.5%,特异性为95.4%。DKK1和VCA-IgA联合检测的诊断AUC为0.849(95%CI为0.783~0.914),敏感性为76.3%,特异性为95.4%。早期鼻咽癌患者DKK1和VCA-IgA联合检测效果优于正常对照组,差异有统计学意义(χ2=23.784,P<0.001)。结论 血清DKK1对鼻咽癌具有潜在的诊断价值,联合检测VCA-IgA有助于鼻咽癌的早期诊断。

Abstract: Objective  To explore the diagnostic value of the combined detection of serum Dickkopf-1(DKK1) and EB viral capsid antigen immunoglobulin A (VCA-IgA) in patients with nasopharyngeal carcinoma (NPC). Methods Serum levels of DKK1 and VCA-IgA were measured by enzymelinked immunosorbent assay (ELISA) for the 80 patients with NPC and 65 normal controls. Receiver operating characteristic (ROC) curve was used to calculate the diagnostic value. Results The serum levels [M(QR)] of DKK1 in patients with NPC were significantly higher than those in normal controls [580.773(429.146)pg/ml vs. 316.174(252.965)pg/ml], with a significant difference (Z=4.846, P<0.000 1). ROC curves showed that the optimum diagnostic cutoff for serum DKK1 was 611.981 pg/ml, with an area under curve (AUC) of 0.734 (95%CI: 0.654-0.815, 50.0% sensitivity, 96.9% specificity). Measurement of VCA-IgA demonstrated an AUC of 0.714 (95%CI: 0.631-0.798, 47.5% sensitivity, 95.4% specificity). The combined detection of DKK1 and VCA-IgA demonstrated an AUC of 0.849 (95%CI: 0.783-0.914, 76.3% sensitivity, 95.4% specificity). For patients with early-stage NPC, the detection effect of combined detection of DKK1 and VCA-IgA was much better than that in normal controls, with a significant difference (χ2=23.784, P<0.001). Conclusion Serum DKK1 has potential diagnostic value for NPC. Combined detection of DKK1 and VCA-IgA may aid the early diagnosis of NPC.
