CCNA2 and cancer: As is shown in Figure 2A, the high expression of CCNA2 is related to poor prognosis of overall survival (OS) in cancers of ACC (p < 0.001), KIRC (p = 0.0014), KIRP (p < 0.001), LGG (p < 0.001), LIHC (p = 0.0041), LUAD (p < 0.001), MESO (p < 0.001), PAAD (p = 0.0047), and SCKM (p = 0.011, Figure 1A).
