CDKN1B and neoplasm: For overall survival on univariate analysis, tumor size (p = 0.033), tumor differentiation (p = 0.047), lymph node status (p = 0.021), FIGO stage (p = 0.011), a high Ki-67 (p = 0.034), cyclinD1 overexpression (p = 0.011), p53 overexpression (p = 0.04) and reduced p27 (p = 0.023) were significant (Table 4).
