Poor prognosis was associated with high EZH2 expression levels in ACC (OS: (P = 6.3e-04, HR = 2); PFS: P = 2.8e-04, HR = 1.8); LGG (OS: P = 1.5e-04, HR = 2); PFS: P = 2.8e-04, HR = 1.8); LIHC (OS: P = 5.6e-5, HR = 2.1); PFS: P = 1.0e-04, HR = 1.8); KICH (OS: P = 0.01, HR = 9.8); and KIRC (OS: P = 0.039, HR = 1.4) (Fig. 2B–F). This evidence concerns the gene EZH2 and adrenal cortex carcinoma.
