目的：系统评价胰岛素样生长因子受体1﹙IGF-1R)的表达与胃癌患者临床病理因素及预后的关系。方法计算机检索Pubmed、EMBASE、Web of Science、CNKI、万方数据库和维普数据库等发表的有关IGF-1R在胃癌组织中的表达及与患者预后的研究；采用Stata 12.0软件进行Meta分析,文献方法学评价参照“欧洲肺癌工作组对肺癌预后因子的评价标准”,文献质量采用纽卡斯尔-渥太华量表来评价。结果共纳入相关文献4篇,累计病例685例。Meta分析结果显示,IGF-1R表达与胃癌肿瘤TNM分期﹙OR=5.20,95%CI：1.12~24.15,P=0.035)、淋巴结转移﹙OR=8.24,95%CI：2.68~25.34,P=0.000)、远处转移﹙OR=17.34,95%CI：6.52~46.15,P=0.000)有关；IGF-1R高表达患者预后明显劣于低表达者﹙HR=2.63,95%CI：1.29~5.40,Z=2.64,P=0.008)。结论 IGF-1R高表达胃癌患者的预后更差。

Objective To systemically evaluate the relationship between the expression of insulin-like growth factor receptor type I ﹙IGF-1R) and prognosis in gastric cancer ﹙GC) patients. Methods A literature search was conducted from PubMed, EMBASE, Web of Science, CNKI, Wanfang and VIP databases to retrieve the clinical studies relevant to IGF-1R expression and its prognostic value in GC patients. Meta-analysis was performed using STATA 12.0 software. The methodology was assessed according to the European Lung Cancer Working Party Quality Scale for Biological Prognostic Factors for Lung Cancer. The quality of studies was assessed using the Newcastle-Ottawa scale. Results Four eligible studies including 685 patients were enrolled for this meta-analysis. Analysis results suggested that up-regulation of IGF-1R in GC patients was significantly associated with TNM staging ﹙OR=5.20, 95%CI:1.12 to 24.15, P=0.035), lymph node metastasis ﹙OR=8.24, 95%CI:2.68 to 25.34, P=0.000) and distant metastasis﹙OR=17.34, 95%CI:6.52 to 46.15, P=0.000). Moreover, up-regulated IGF-1R expression was significantly associated with poor overall survival of gastric cancer patients﹙HR=2.63, 95%CI:1.29 to 5.40, Z=2.64, P=0.008). Conclusion High IGF-1R expression may be an adverse prognostic factor in gastric cancer patients.
