Figure 4B displayed MKI67 expression was remarkably related to DSS of 9 cancer types, including ACC, KIRC, KIRP, LGG, LIHC, LUAD, MESO, PAAD, and SKCM. Figure 4C indicated that increased MKI67 expression was significantly associated with KIRP, LIHC, PAAD, STAD, and THCA of DFS. Notably, MKI67 was a risk factor for death in patients with KIRP, LIHC, PAAD and THCA but a protective factor for STAD. Figure 4D demonstrated MKI67 expression appreciably affected PFS in patients with KIRP, LIHC, PAAD, STAD, and THCA. The gene discussed is MKI67; the disease is adrenal cortex carcinoma.
