It was found that increased levels of KIFC1 expression were significantly associated with poor OSs of ACC [HR, 6; p < 0.0001]; KIRC [HR, 1.5; p = 0.014]; KIRP [HR, 2.5; p = 0.0036]; LGG [HR, 2.3; p < 0.0001]; LIHC [HR, 2.2; p < 0.0001]; LUAD [HR, 1.5; p = 0.0077]; MESO [HR, 3.4; p < 0.0001]; PAAD [HR, 1.8; p = 0.0059]; SARC [HR, 1.7; p = 0.011]; and SKCM [HR, 1.5; p = 0.0029] (Figure 4A). The gene discussed is KIFC1; the disease is adrenal cortex carcinoma.
