We took advantage of four microarray experiments deposited in GEO (GSE34620, GSE63155, GSE17674, GSE63156) and, using shinyGEO, we analyzed EPHA2 gene expression levels in relation to tissue type (tumor vs. normal), patients’ characteristics (age, gender) and clinical outcome (overall survival and recurrence data) in a total of 246 Ewing’s sarcoma patients. The gene discussed is EPHA2; the disease is Ewing sarcoma.
