EPOR and adrenal cortex carcinoma: The DFS showed that EPOR was significantly associated with the prognosis of adrenocortical carcinoma (ACC) (HR = 0.19, p < 0.05), PAAD (HR = 0.65, p < 0.05), CHOL (HR = 1.05, p < 0.05), LUSC (HR = 1.24, p < 0.05), PRAD (HR = 3.90, p < 0.01), and TGCT (HR = 3.17, p < 0.05) (Figure 3C).
