EPOR and sarcoma: The analysis showed that EPOR expression was positively correlated with the TMB of COAD (p = 2.5e - 05), sarcoma (SARC) (p = 0.012), and SKCM (p = 0.0067) and negatively correlated with the TMB of BRCA (p = 3.6e - 13), CESC (p = 0.03), KIRP (p = 0.01), LIHC (p = 0.0006), and PAAD (p = 0.019) (Figure 9A).
