BACKGROUND/AIMS: Accumulating studies have reported that IGF-1R (Insulin-like growth factor-1 receptor) is aberrantly expressed in NSCLC (non-small cell lung cancer), but the role of IGF-1R in NSCLC remains controversial. The present paper assessed the precise role of IGF-1R in NSCLC.
METHODS
We comprehensively searched PubMed, EMBASE, and Web of Science in March 2017. Combined HRs and ORs were used to evaluate the prognostic and clinicopathological significance of IGF-1R in NSCLC respectively.
RESULTS
A total of 10 eligible studies including 8 on overall survival, and 10 on clinicopathological features were identified from the databases. The results showed that high expression of IGF-1R was associated with shorter OS (overall survival) of NSCLC patients (pooled HR 1.17,95 % CI 1.00-1.36). In addition, we found that IGF-1R was related to smoking status (OR=1.82, 95 % CI=1.35-2.44) and IGF-1R tended to be highly expressed in SCC (squamous cell carcinoma) (OR=3.40 95 % CI: 1.95-5.95).
CONCLUSIONS
In summary, this meta-analysis revealed that high expression of IGF-1R was associated with poor prognosis in NSCLC.
背景/目的：越来越多的研究报道胰岛素样生长因子1受体（IGF-1R）在非小细胞肺癌（NSCLC）中异常表达，但IGF-1R在NSCLC中的作用仍存在争议。本文评估了IGF-1R在NSCLC中的确切作用。
方法
我们于2017年3月全面检索了PubMed、EMBASE和科学网。合并的风险比（HRs）和比值比（ORs）分别用于评估IGF-1R在NSCLC中的预后和临床病理意义。
结果
从数据库中总共鉴定出10项符合条件的研究，其中8项关于总生存期，10项关于临床病理特征。结果显示，IGF-1R高表达与NSCLC患者较短的总生存期（OS）相关（合并HR 1.17，95%CI 1.00-1.36）。此外，我们发现IGF-1R与吸烟状况相关（OR=1.82，95%CI=1.35-2.44），且IGF-1R在鳞状细胞癌（SCC）中倾向于高表达（OR=3.40，95%CI：1.95-5.95）。
结论
总之，这项荟萃分析表明IGF-1R高表达与NSCLC预后不良相关。
