目的:评价甲胎蛋白(alpha-fetoprotein,AFP)联合高尔基体蛋白73(Golgi protein 73,G P73)检测对原发性肝癌诊断的价值,以期为临床医生提供参考.方法:检索Pub Med、EMbase、Medline、万方数据知识服务平台、CNKI、中国生物医学文献数据...目的:评价甲胎蛋白(alpha-fetoprotein,AFP)联合高尔基体蛋白73(Golgi protein 73,G P73)检测对原发性肝癌诊断的价值,以期为临床医生提供参考.方法:检索Pub Med、EMbase、Medline、万方数据知识服务平台、CNKI、中国生物医学文献数据库等中外数据库2015-02之前发表的,关于AFP联合GP73检测对原发性肝癌诊断价值的研究,并对纳入文献的参考文献进行二次检索.严格按照纳入标准和排除标准选择文献、提取数据,并对纳入的文献行质量评价、异质性分析.采用Meta Disc1.4、Stata12.0软件进行Meta分析.结果:共纳入符合标准的文献19篇.AFP、G P 7 3单项检测对原发性肝癌诊断合并后的敏感度、特异度、曲线下面积(area under the curve,A U C)、Q指数分别为0.58(0.56-0.61)、0.84(0.83-0.86)、0.7642、0.7052和0.78(0.76-0.80)、0.97(0.86-0.88)、0.8848、0.8153.A F P联合G P73检测合并后的敏感度、特异度、AUC、Q指数分别为0.88(0.87-0.90)、0.82(0.80-0.83)、0.9461、0.8853.联合检测的A U C、Q指数明显高于AFP、GP73单项检测,Z检验提示差异有统计学意义(均P<0.05).结论:AFP联合GP73检测对原发性肝癌的诊断价值较高,对临床医生有一定的参考价值.展开更多
