MKI67 and metastatic malignant neoplasm in the lymph nodes: Next, we performed a univariate analysis on 183 patients, and the results showed that DFS was associated with axillary lymph node metastasis (p < 0.0001), MNX1 protein expression level (p = 0.013), and radiotherapy status (p = 0.037) (Table 2) but not associated with the patient’s age, menopausal status, histological grade, tumor size, hormone receptor level, or Ki67 level.
