Pan-cancer analysis explored the correlation of EPOR expression with prognosis, microRNAs (miRNAs), immune cell infiltration, tumor microenvironment (TME), immune checkpoint genes, chemokines, tumor mutation burden (TMB), microsatellite instability (MSI), methyltransferases, and DNA mismatch repair (MMR) genes in 33 tumors. Here, EPOR is linked to cancer.
