Abstract

背景与目的已有的研究表明:在多种恶性肿瘤中发现转移相关蛋白1(metastasis associated protein 1, MTA1)发挥着促进肿瘤侵袭与转移的作用,且与肿瘤患者预后不佳有关。目前MTA1在肺癌中的预后作用仍有争议,故我们采用meta分析的方法评估其在肺癌患者中的预后价值。方法通过计算机检索PubMed、Embase、万方数据库、中国生物医学文献数据库、中国知网等数据库,收集纳入研究MTA1表达与肺癌预后关系的文献及相关数据,采用Stata 12.0软件进行数据分析,合并值为风险比(hazard ratio, HR)。结果总共纳入8项研究共712例中国肺癌患者,对这些研究进行异质性检验,发现存在异质性(I2=59.0%, P=0.017),故采用随机效应模型进行数据合并得HR=2.07(95%CI: 1.42-3.02, P < 0.001)。同时分层分析显示在非小细胞肺癌(non-small cell lung cancer, NSCLC)中各研究无明显异质性(I2=47.0%, P=0.093),采用固定效应模型合并得HR=1.66(95%CI: 1.27-2.18, P < 0.001)。结论MTA1高表达可能是中国NSCLC患者预后不良的一个指标,在肺癌及小细胞肺癌中的预后价值尚缺乏证据。
