Comprehensive analysis of non-small-cell lung cancer microarray datasets identifies several prognostic biomarkers.

To find accurate and effective biomarkers for diagnosis of non-small-cell lung cancer (NSCLC) patients. We downloaded microarray datasets GSE19188, GSE33532, GSE101929 and GSE102286 from the database of Gene Expression Omnibus. We screened out differentially expressed genes (DEGs) and miRNAs (DEMs) with GEO2R.
