TCGA data analysis revealed that high AREG expression correlates with poor prognosis in lung squamous cell carcinoma (LUSC), head and neck squamous carcinoma (HNSC), lung adenocarcinoma (LUAD), acute myeloid leukemia (LAML), liver hepatocellular carcinoma (LIHC), and pancreatic adenocarcinoma (PAAD) (Figure 9G). This evidence concerns the gene AREG and acute myeloid leukemia.
