We conducted a pooled analysis comparing the efficacy of an immunohistochemistry (IHC) assay using the D5F3 antibody with that of fluorescence in situ hybridization (FISH) for detecting ALK gene rearrangement in NSCLC patients. A total of 32 studies involving 5805 samples were included in this review. Pooled sensitivity for D5F3 IHC was 0.97 (95%CI: 0.93-0.98), specificity was 0.99 (95%CI: 0.98-1.00), PLR was 119.20 (95%CI: 57.79-245.89), NLR was 0.03 (95%CI: 0.02-0.07), DOR was 3526.66 (95%CI: 1344.71-9249.03), and AUROC was 1.00 (95%CI: 0.99-1.00). Meta-regression revealed that specimen type was a source of heterogeneity for specificity, and specimen type and FISH signal distance were sources of heterogeneity in the joint model. Subgroup analysis revealed that sensitivity and specificity were higher when the FISH signal distance standard was ≥ 2 than when it was ≥ 1. Sensitivity was higher for tumor specimens than for cell specimens; specificity was higher for cell specimens than for tumor specimens. In conclusion, the D5F3 IHC assay was nearly as effective as FISH for detection of ALK gene rearrangement in NSCLC patients.
我们进行了一项汇总分析,比较使用D5F3抗体的免疫组织化学(IHC)检测法与荧光原位杂交(FISH)检测非小细胞肺癌(NSCLC)患者ALK基因重排的疗效。本综述共纳入32项研究,涉及5805个样本。D5F3 IHC的汇总敏感性为0.97(95%CI:0.93 - 0.98),特异性为0.99(95%CI:0.98 - 1.00),阳性似然比(PLR)为119.20(95%CI:57.79 - 245.89),阴性似然比(NLR)为0.03(95%CI:0.02 - 0.07),诊断比值比(DOR)为3526.66(95%CI:1344.71 - 9249.03),曲线下面积(AUROC)为1.00(95%CI:0.99 - 1.00)。Meta回归显示,标本类型是特异性异质性的来源,标本类型和FISH信号距离是联合模型中异质性的来源。亚组分析显示,当FISH信号距离标准≥2时,敏感性和特异性高于≥1时。肿瘤标本的敏感性高于细胞标本;细胞标本的特异性高于肿瘤标本。总之,在检测NSCLC患者的ALK基因重排方面,D5F3 IHC检测法与FISH几乎同样有效。
