The PFS showed that EPOR was significantly associated with the prognosis of BLCA (HR = 0.67, p < 0.05), PAAD (HR = 0.56, p < 0.01), CHOL (HR = 3.01, p < 0.05), COAD (HR = 1.74, p < 0.01), LUSC (HR = 1.47, p < 0.05), MESO (HR = 1.72, p < 0.05), PRAD (HR = 2.02, p < 0.01), and TGCT (HR = 2.82, p < 0.01) (Figure 3A). This evidence concerns the gene EPOR and bladder transitional cell carcinoma.
