In addition, in the multivariate analyses for DFS and OS, lymph node metastasis and HER-2/TNBC molecular subtype were independent molecular biomarkers for DFS (Table 2), while high grade, middle tumour size (>2, ≤5 cm), lymph node metastasis, and TNBC subtype were significantly and independently associated with OS (Table 3). Here, ERBB2 is linked to metastatic malignant neoplasm in the lymph nodes.
