早期肝细胞癌(HCC)的非侵入性生物标志物可以带来巨大的好处。目前可用的 HCC 肿瘤标志物没有太大的临床意义。在这项研究中,我们研究了使用一组血清 microRNA (miRNA) 作为新型肿瘤标志物与血清甲胎蛋白 (AFP) 结合诊断 HCC 的潜力。通过定量实时聚合酶链反应 (qRT-PCR) 评估了 150 名受试者(90 例 HCC 病例和 60 例非癌症病例)中四种 miRNA 的血清表达。进行逻辑回归分析以评估 miRNA 在 HCC 检测中的潜在用途。接受者操作特征曲线用于评估诊断准确性。一组血清 miRNA(miR-125b、miR-223、miR-27a 和 miR-26a)与 AFP 结合使用,在调整年龄和性别后有助于将 HCC 患者与非癌症组患者区分开来,曲线下面积为 0.870。此外,使用 miR-125b/miR-27a 组合在 AFP 阴性 (−) 受试者中区分 HBV 相关早期 HCC 具有高敏感性 (80.0%) 和特异性 (87.2%)。血清 miR-125b、miR-223、miR-27a 和 miR-26a 的组合作为二线测试可以帮助检测 AFP (-) 受试者的 HCC。与单一标志物相比,miR-125b/miR-27a/AFP 组合对诊断早期 HCC 具有更高的敏感性和特异性。
Non-invasive biomarkers of early-stage hepatocellular carcinoma (HCC) could offer immense benefits. Currently available tumor markers for HCC are of not much clinical relevance. In this study, we investigated the potential for using a panel of serum microRNAs (miRNAs) as novel tumor markers in conjunction with serum alpha-fetoprotein (AFP) for diagnosis of HCC. Serum expression of four miRNAs was assessed in 150 subjects (90 cases of HCC and 60 cases without cancer) by quantitative real-time polymerase chain reaction (qRT-PCR). Logistic regression analysis was performed to assess the potential use of miRNAs for detection of HCC. Receiver operating characteristic curves were used to evaluate diagnostic accuracy. A panel of serum miRNAs (miR-125b, miR-223, miR-27a, and miR-26a) used in conjunction with AFP helped differentiate HCC patients from those in the non-cancer group after adjusting for age and gender, with the area under the curve of 0.870. In addition, the use of miR-125b/miR-27a panel differentiated HBV-related early-stage HCC with a high sensitivity (80.0 %) and specificity (87.2 %) in AFP-negative (−) subjects. A combination of serum miR-125b, miR-223, miR-27a, and miR-26a as a second-line tests could help detect HCC in AFP (−) subjects. The panel of miR-125b/miR-27a/AFP had a higher sensitivity and specificity for diagnosis of early-stage HCC as compared to that of a single marker.
