目的:探讨IGFBP?3基因转录表达水平在胶质母细胞瘤( GBM)患者预后评价中的意义。方法采用训练?验证分组方式,利用GBM在线样本库TCGA、REMBRANDT和GSE16011中病例的临床资料和芯片数据,通过Kaplan?Meier法和Cox回归分析,探讨IGFBP?3 mRNA表达与GBM患者总生存时间( OS)的关系。结果在TCGA训练组中, IGFBP?3基因高表达患者的中位OS为14?3个月(95%CI:12?5~16?1个月),显著差于低表达的15?9个月(95%CI:13?7~18?1个月),差异具有统计学意义( P=0?002);REMBRANDT病例组中,IGFBP?3高、低表达组患者的中位OS分别为13?2个月(95%CI:10?8~15?6个月)和16?8个月(95%CI:13?4~20?1个月),差异具有统计学意义( P=0?036); GSE16011病例组的中位OS分别为7?4个月(95%CI:6?6~8?3个月)和13?1个月(95%CI:9?2~17?0个月),差异具有统计学意义(P<0?001)。多因素Cox回归分析及亚型分层分析表明,IGFBP?3 mRNA表达分组的预后评价能力可能依赖于不同的GBM基因表达亚型。结论 IGFBP?3 mRNA表达水平与GBM患者的临床预后密切相关,且可能与不同的基因表达亚型有关。

Objective To discuss the prognostic value of IGFBP?3 mRNA expression in glioblastoma (GBM). Methods The genomic mRNA expression data and patients? clinical data from three different GBM datasets, TCGA, REMBARNDT and GSE16011 were obtained, and the prognostic value of IGFBP?3 mRNA expression in GBM patients were investigated using Kaplan?Meier method and multivariate Cox regression analysis. Results In the TCGA dataset, patients with higher IGFBP?3 mRNA expression were associated with shorter overall survival (OS) than patients with lower IGFBP?3 mRNA expression.the median OS was 14?3 months ( 95% CI:12?5?16?1) vs. 15?9 months ( 95% CI:13?7?18?1) ,with significant differences ( P=0?002);similarly, in another two val?idation datasets, patients in high expression groups had shorter OS than those in low expression groups: REMBRANDT dataset:13?2 months (95% CI:10?8?15?6) vs. 16?7 months (95% CI 13?4?20?1), with significant differences (P=0?036); GSE16011 dataset:7?4 months ( 95% CI:6?6?8?3) vs. 13?1 months ( 95% CI:9?2?17?0) ,with significant differences ( P<0?001) . Cox model indicated that the prognostic value of IGFBP?3 mRNA expression might be dependent on gene expression subtype of GBMs. Conclusion The present study revealed and validated the prognostic value of IGFBP?3 mRNA expression in GBM patients, and suggested its dependence on gene expression subtypes of GBMs.
