TOP2A and cancer: Identified differentially expressed genes (DEGs) that were shared in various cancer types and constructed a diagnostic model using 10 upregulated DEGs (CCNA2, CDK1, CCNB1, CDC20, TOP2A, BUB1B, AURKB, NCAPG, CDC45, and TTK).AUC of 0.894 was obtained for discriminating cancer from normal samples.
