CCNA2 and pancreatic adenocarcinoma: More importantly, CCNA2 mRNA expression was significantly correlated with the patient prognosis in ACC, COAD, KICH, KIRC, KIRP, LGG, LIHC, LUAD, MESO, PAAD, PRAD, SARC, THYM, and UVM, suggesting that CCNA2 plays an important role in the progression of pancancer, especially KIRC patients with high expression of CCNA2 holding a worse prognosis.
