To identify the clinical significance of IL13RA2 in HCC, we performed a Kaplan–Meier survival analysis in Kaplan–Meier Plotter (http://kmplot.com/analysis/index.php?p=service%26cancer=liver_rnaseq), which integrated three independent transcriptomic datasets: TCGA, Gene Expression Omnibus (GEO): http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE20017 and GEO: http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE984323. Here, IL13RA2 is linked to hepatocellular carcinoma.
