MKI67 and metastatic malignant neoplasm in the lymph nodes: In a model accounting for the mitotic count, the Ki67 value, and the presence of lymph node metastases, at a multivariate analysis, only mitotic count remains an independent prognostic factor (OR 1.51 (1.0-2.29)), while the presence of metastatic lymph nodes loses its significance (OR 26.71 (0.60-1180.48)).
