ABSTRACT
<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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).</p><p><b>CONCLUSION</b>High IGF-1R expression may be an adverse prognostic factor in gastric cancer patients.</p>
