[摘要] 目的 采用Meta分析评价甲胎蛋白异质体(AFP-L3)诊断原发性肝癌(PHC)的价值。方法 检索Pubmed、Embase、中国知网、万方、维普等数据库中有关AFP-L3诊断PHC的相关文献,按照纳入及排除标准进行文献筛选。采用QUADAS-2评价纳入文献的偏倚风险。采用Meta Dis C1.4综合评价AFP-L3对PHC病人的诊断价值。结果 本研究共纳入14篇文献,Meta分析提示纳入文献具有非阈值效应而引起的异质性。随机效应模型分析显示合并灵敏度为0.68(95%CI=0.66~0.70),合并特异度为0.91(95%CI=0.90~0.92),SROC曲线下面积(AUC)为0.907(95%CI=0.83~0.92),诊断比值比为35.79(95%CI=22.06~58.07)。结论 AFP-L3 对PHC病人的早期诊断具有较高的特异度和较大的AUC,对PHC的早期临床诊断具有一定的价值。

[ABSTRACT] Objective To investigate the value of alpha-fetoprotein-L3 (AFP-L3) in the diagnosis of primary hepatic carcinoma (PHC) through a Meta-analysis. Methods The databases including PubMed, Embase, CNKI, Wanfang Data, and VIP were searched for the articles on AFP-L3 in the diagnosis of PHC, and the articles were screened based on including and exclusion criteria. The QUADAS-2 tool was used to evaluate the risk of bias of included articles. Meta Dis C1.4 was used to investigate the diagnostic value of AFP-L3 in patients with PHC. Results A total of 14 articles were included, and the meta-analysis showed that the heterogeneity of the included studies was caused by the non-threshold effect. The random effects model analysis showed a pooled sensitivity of 0.68 (95% confidence interval (CI):0.66-0.70), a pooled specificity of 0.91 (95%CI:0.90-0.92), an area under the summary receiver operating characteristic curve (AUC) of 0.907 (95%CI:0.83-0.92), and a diagnostic odds ratio of 35.79 (95%CI:22.06-58.07). Conclusion AFP-L3 has high specificity and AUC in the early diagnosis of PHC, and therefore, it has a certain value in the early clinical diagnosis of primary liver cancer.

在全球范圍内,原发性肝癌(PHC)是第6位最易罹患的癌症,在癌症死因中居第3位[1]。特别是在亚太地区有很高的发病率,在我国恶性肿瘤排名中,肝癌死亡率高居第2位。而PHC主要是由肝细胞或肝内胆管上皮细胞发生恶变而引起的肿瘤。目前,甲胎蛋白异质体(AFP-L3)在PHC的前期筛查、治疗效果的评判以及预后判断等方面均具有较大的价值,但其结论不尽相同。本研究收集国内外公开发表的有关AFP-L3诊断肝脏癌症的文献,采用Meta分析来评价AFP-L3在PHC诊断中的价值,为PHC的早期临床诊断提供参考依据。
