目的:通过meta分析比较EBV DNA和VCA-IgA对鼻咽癌的诊断价值,为鼻咽癌的筛查方法提供重要依据。方法:采用Medline数据库(1966年1月- 2012年1月)、EMBASE数据库(1988年1月- 2012年1月)和中国生物医学数据库(1980年1月- 2012年1月)检测EBV DNA和VCA-IgA在鼻咽癌诊断中的作用。Meta-DiSc统计软件进行分析。结果:最终分析纳入了27项病例对照和队列研究。我们的荟萃分析共纳入1554例病例和2932例对照。EBV-DNA诊断鼻咽癌的敏感性、特异性、阳性似然(+LR)和似然阴性(-LR)分别为0.75(0.72-0.76)、0.87(0.85-0.88)、6.98(4.50-10.83)和0.18(0.11-0.29),VCA-IgA诊断鼻咽癌的敏感性、特异性、阳性似然(+LR)和阴性似然(-LR)分别为0.83(0.81-0.85)、0.85(0.83-0.86)、10.89(5.41-21.93)和0.20(0.14-0.29)。EBV DNA检测SROC为0.939,VCA-IgA检测SROC为0.936。亚组分析显示,在高质量和低质量研究中,EBV-DNA与VCA-IgA相比,在总接受者操作曲线下的面积更大。结论:我们的荟萃分析表明EBV DNA在鼻咽癌诊断中具有较高的敏感性和特异性。
Objective: We conducted a meta-analysis to compare the EBV DNA and VCA-IgA in diagnosis of Nasopharyngeal Carcinoma, and provide important evidence for screening method of NPC. Methodology: Three databases, Medline (from Jan. 1966 to Jan. 2012), EMBASE (from January 1988 to Jan. 2012) and Chinese Biomedical Database (from January 1980 to Jan. 2012) were used to detect the role of EBV DNA and VCA-IgA in diagnosis of NPC. Meta-DiSc statistical software was used for analysis. Results: Twenty seven case-control and cohort studies were included in final analysis. A total of 1554 cases and 2932 controls were included in our meta-analysis. The Sensitivity specificity, positive likelihood (+LR) and likelihood negative (-LR) of EBV-DNA in diagnosis of NPC were 0.75(0.72-0.76), 0.87(0.85-0.88), 6.98(4.50-10.83) and 0.18(0.11-0.29), respectively, and they were 0.83(0.81-0.85), 0.85(0.83-0.86), 10.89(5.41-21.93) and 0.20(0.14-0.29) for VCA-IgA. The SROC for EBV DNA detection was 0.939, while this was 0.936 for VCA-IgA detection. The subgroup analysis showed EBV-DNA had larger areas under the summary receiver operator curve when compared with VCA-IgA in high quality and low quality studies. Conclusion: Our meta-analysis indicated the EBV DNA had higher sensitivity and specificity in diagnosis of NPC.
