To determine whether the addition of trastuzumab to chemotherapy (TC or AC→WP) improves invasive disease-free survival (IDFS) in women with resected node-positive or high-risk node-negative breast cancer which is reported as HER2-low by all HER2 testing performed.

Patient Inclusion Criteria:

  • Age ≥ 18 years
  • The tumor must be unilateral invasive adenocarcinoma of the breast on histologic examination
  • All of the following staging criteria (according to the 7th edition of the AJCC Cancer Staging Manual) must be met:
    1. By pathologic evaluation, primary tumor must be pT1-3
    2. By pathologic evaluation, ipsilateral nodes must be pN0, pN1 (pN1mi, pN1a, pN1b, pN1c), pN2a, pN2b, pN3a, or pN3b

  • If pN0, one of the following criteria must be met:
    1. pT2 and estrogen receptor (ER) negative and progesterone receptor (PgR) negative
    2. pT2 and ER positive (PgR status may be positive or negative) and either grade 3 histology or Oncotype DX® Recurrence Score of = 25
    3. pT3 regardless of hormone-receptor status, histologic grade, and Oncotype DX® Recurrence Score

Patient Exclusion Criteria:

  • None of the following allowed:
    1. No T4 tumors including inflammatory breast cancer
    2. No definitive clinical or radiologic evidence of metastatic disease Note: Chest imaging (mandatory for all patients) and other imaging (if required) must have been performed within 90 days prior to randomization]
    3. No synchronous or previous contralateral invasive breast cancer (patients with synchronous and/or previous contralateral DCIS or LCIS are eligible)
    4. No previous ipsilateral invasive breast cancer or ipsilateral DCIS (patients with synchronous or previous ipsilateral LCIS are eligible)
