Our current multivariate analysis revealed that a ≥ 55% baseline Ki-67 labeling index with luminal (HR 2.1, 95% CI,1.04–4.25), and ≥ 4 lymph node metastases at surgery (HR 1.9, 95% CI, 1.07–3.51) seemed to be correlated with the 3Y DFS outcome. Here, MKI67 is linked to metastatic malignant neoplasm in the lymph nodes.
