Tumor subtype (hormone-dependent HER2 negative, hormone-dependent HER2 positive, non-hormone dependent HER2 positive or triple negative) was the only independent predictor of pCR in a logistic-regression multivariate model (OR: 1.87; 95% confidence interval (CI): 1.19 to 2.93; P = 0.006). Here, ERBB2 is linked to neoplasm.
