ERBB2 and neoplasm: HER2-overexpressing and triple negative breast cancer women received less reconstruction surgery than luminal ones, in patients with high-grade tumor (poorly or undifferentiated) and advanced stage disease (AJCC stage III) (P=0.011), whereas there was no significant difference in reconstruction rates among the 4 subtypes in patients with low-grade tumor (well differentiated) and early stage disease (AJCC stage I) (P = 0.286, Figure 2).
