The PCR rate of patients with triple-negative, Her-2-positive, and Luminal B2 breast cancer was higher than those with Luminal A and Luminal B1 breast cancer, whereas these differences were not statistically significant, possibly because only a few patients who received neoadjuvant chemotherapies were included in the present study, where chemotherapeutic regimes were not completely the same as those of previous studies. Here, ERBB2 is linked to breast carcinoma.
