Insulin-like growth factor receptor 1 (IGF1R) expression and survival in non-small cell lung cancer patients: a meta-analysis.

ABSTRACT: The insulin-like growth factor receptor-1 (IGF1R) plays an important role in cancer progression. Previous studies have been controversial with respect to the associations between IGF1R expression and non small cell lung cancer (NSCLC) prognosis. Thus, we performed a meta-analysis to investigate the prognostic value of IGF1R expression in NSCLC patients and the relationship between the expression of IGF1R and clinical characteristics. Two independent reviewers searched PubMed, Embase, Ovid Medline and CNKI to identify eligible studies. Overall survival (OS), disease free survival (DFS) and clinicopathological characteristics were collected from included studies. Pooled hazard ratios (HRs) or odds ratios (ORs) with 95% confidence interval (95% CI) were calculated to estimate the effect. 17 s
