Patients with HER-2 (MRI tumor ≤ 2 cm), or TNBC (MRI tumor size ≤ 2 cm, MRI tumor size ≤ 3 cm, and pathologic tumor size ≤ 3 cm) were found to have MRI-ALN-NPV higher than 90%, and these FN cases were limited to low axillary tumor burden (N1, Table 4). The gene discussed is ERBB2; the disease is neoplasm.
