Low nuclear Cdk5 expression was associated with lower Figo stage (χ2 = 15.327, df = 3, P = .002), lower tumour grade (χ2 = 6.211, df = 2, P = .045), absence of residual disease (χ2 = 8.107, df = 2, P = .017) and tumour histology (χ2 = 26.522, df = 6, P < .001; Table 1). Here, CDK5 is linked to neoplasm.
