The univariate-adjusted odds ratio for pCR was 3.046 (95% confidence interval [CI]: 1.475–6.290) for HER2+ subtype, 5.091 (95% CI: 2.900–8.939) for tumor size < 10 mm on MRI after NAC, 41.667 (95% CI: 5.276–329.047) for radiologic CR on MRI, and 2.824 (95% CI: 1.734–4.598) for partial mastectomy. This evidence concerns the gene ERBB2 and neoplasm.
