CDK9 expression was correlated with histological grade (p = 0.000), International Federation of Gynecology and Obstetrics (FIGO) stage (p = 0.000), depth of muscular invasion (p = 0.034), and lymph node metastasis (p = 0.000) but showed no significant association with pathological type (p = 0.985), as shown in Table 1. This evidence concerns the gene CDK9 and metastasis.
