In terms of clinical characteristics, Liu et al. [3] reported that invasive papillary carcinoma occurs mostly in the postmenopausal period and is associated with better 5-year overall survival rate and disease-free survival rate than general invasive ductal carcinoma, although the distribution of the four biological subtypes (luminal A, luminal B, HER2, triple-negative) was similar to that of general-type invasive ductal carcinoma. The gene discussed is ERBB2; the disease is invasive ductal breast carcinoma.
