摘要 目的:用Meta分析方法评价雌激素受体表达对肺癌预后的价值。方法:计算机检索PubMed、EMBASE、中国生物医学文献数据库、万方、维普和中国期刊全文数据库,纳入符合标准的文献,采用RevMan5.1软件进行数据分析。结果:共纳入5个研究,5个研究存在异质性(I2=0.47)。 I2<50%且P=0.11>0.1,可以认为异质性对结果影响不大,在分析中可以忽略,故选用固定效应模型(fixed-effect model,FE)。合并总风险比(hazard ratio, HR )为0.49,95%CI为0.37~0.64,P<0.00001。合并HR值0.49可以认为雌激素受体β亚型(estrogen receptor-β, ER-β)表达对预后的影响为有利的。漏斗图分析示基本对称,可以认为结果不受发表偏倚的影响。结论:ER-β的表达是肺癌预后的有利因素。
