2、附试验检测血清Rta—IgG、VCA—IgA和EBNA1一IgA抗体。以临床病理诊断为金标准,分析各血清检测指标的准确度、灵敏度及特异度,并根据Rta—IgG、VCA—IgA和EBNA1IgA抗体检测结果绘制受试者工作特征(ROC)曲线。结果NPC组患者血清RtaIgG、VCAIgA和EBNA1一IgA抗体水平均高于对照组,差异均有统计学意义(P%0.05)。NPC组和对照组3种抗体均阳性者分别占56.25、0.00。Rta—IgG、VCA~IgA和EBNA1一IgA抗体的ROC曲线下面积分别为0.798、0.889和0.895.灵敏度分别为85.37、87.56和88.34,特异度分别
3、为93.45、96.13和96.37。三者联合检测的灵敏度和特异度分别为96.48、98.98。结论联合检测Rta—IgG、VCA—IgA和EBNA1一IgA抗体能够明显提高临床对NPC患者的早期筛查与诊断效能,具有重要的临床应用价值。关键词:鼻咽癌;EB病毒;抗体DOI:10.3969/j.issn.1673—4130.2015.13.023文献标识码:A文章编号:1673—4130(2015)13—1856-03DiagnosticvalueofcombineddetectionofRta—IgG-EBNA1一lgAandVCA-IgAantibodiesinnasopharynge
