目的:系统评价微小RNA(miRNA)定量PCR检测对乳腺癌的诊断价值。方法通过对Medline、Embase以及Co-chrane Library数据库的检索,选出miRNA与乳腺癌诊断相关的研究。按照纳入和排除标准独立筛选文献,提取相关数据建立四格表,用诊断性实验准确性质量评价工具(QUADAS)评价纳入研究的文献质量。统计分析软件选用MetaDisc1.4、STATA11.0,分析miRNA的诊断价值。结果16个研究被纳入,其中包括1303例病例组样本,711例对照组样本。研究间存在阈值效应(Spearman相关系数为-0.758,P=0.001)。采用随机效应模型进行meta分析,miRNA的合并敏感度为0.77(95% CI:0.75~0.79),合并特异度为0.77(95% C I:0.74~0.80),阳性似然比为4.19(95% C I:2.79~6.30),阴性似然比为0.25(95% C I:0.19~0.35),诊断比值比为19.91(95% CI:9.68~40.95)。综合受试者工作特征(SROC)曲线的曲线下面积(AUC)为0.8950。结论评价结果提示miRNA在乳腺癌诊断中一定的精确性,但它还不足以替代现有的诊断方法,乳腺癌的诊断仍然需要结合临床症状和传统检查共同进行。

Objective To systematically review the diagnostic value of microRNA(miRNA) quantitation in breast cancer .Meth-ods Literatures about miRNA and breast cancer diagnosis were selected by retrieving Medline ,Embase and Cochrane Library .Ac-cording to the inclusion and exclusion criteria ,the literatures were independently screened ,and a 2 × 2 contingency table was con-structed .Quality of literatures was assessed by quality assessment of diagnostic accuracy studies(QUADAS) .Statistical analysis was performed by employing Meta-Disc 1 .4 software and STATA 11 .0 .Results 16 studies were included ,which contained 1 303 patients and 711 control samples .There were threshold effects among these studies (the spearman′s correlation coefficient was-0 .758 ,P=0 .001) .A random effects model was used for meta-analysis .The summary sensitivity ,specificity ,positive likelihood ratio ,negative likelihood ratio ,and diagnostic odds ratio for miRNA in breast cancer diagnosis were 0 .77(95% CI:0 .75 -0 .79) , 0 .77(95% CI:0 .74-0 .80) ,4 .19(95% CI:2 .79-6 .30) ,0 .25(95% CI:0 .19-0 .35) ,19 .91(95% CI:9 .68-40 .95) .The area un-der curve of SROC was 0 .895 0 .Conclusion These results suggest that miRNAs have potential value to diagnose breast cancer . However ,effective diagnosis of breast cancer still needs to be conducted with assistance of clinical findings and traditional lab inves-tigations .
