It was reported that high expression of CDC20 (cell division cycle protein 20) is associated with poor survival in astrocytoma (Ding et al., 2017), cutaneous squamous cell carcinoma (Chu et al., 2019) and pancreatic ductal adenocarcinoma (Dong et al., 2019). This evidence concerns the gene CDC20 and astrocytoma (excluding glioblastoma).
