As a consequence of the analysis, PBK, PRC1, CDC5, CDC20, TOP2A, and NCAPG were significantly correlated with OS (Figures 6A–F), DSS (Supplementary Figures S1A–F), and PFI (Supplementary Figures S1G–L), indicating that they were good predictors of the prognosis of HCC. Here, TOP2A is linked to hepatocellular carcinoma.
