Note. The pathological molecular subtypes and histological grades of breast cancer are only analyzed for the components of invasive breast cancer. Because no sentinel lymph node metastasis occurred in breast carcinoma in situ, in order to eliminate its interference, factors such as “Ki-67 (IHC),” HER-2 (IHC) “only analyzed cases of invasive breast cancer.
