The relatively higher expression of CDC20 (HR = 2.3; P = 3.8e-06), CDK1 (HR = 2; P = 0.00017), MAD2L1 (HR = 1.7; P = 0.0047), BUB1 (HR = 1.8; P = 0.001), BUBIB (HR = 1.7; P = 0.0028), CCNB1 (HR = 2; P = 0.00015), and CCNA2 (HR = 1.7; P = 0.0037) were associated with a poor prognosis in HCC patients, while only CCNB2 (HR = 1.4; P = 0.052) showed no statistical significance in the overall survival of patients (Figure 6). Here, CCNA2 is linked to hepatocellular carcinoma.
