Inclusion Criteria:

The patient must have signed and dated an IRB-approved consent form that conforms to federal and institutional guidelines.

• Female
• 18 years or older
• ECOG performance status of 0 or 1

• Eligible tumors must meet one of the following criteria:

  • Operable (T1c, T2-3, N0-1, M0)
  • Locally advanced (T2-3, N2-3, M0 or T4a-c, any N, M0)
  • Inflammatory breast cancer (T4d, any N, M0)

• Staging evaluation:

  • History and physical exam, cbc, chemistry profile
  • CT Chest/Abdomen/Pelvis and a bone scan or PET/CT as needed
• Diagnosis of invasive adenocarcinoma made by core needle biopsy
• Breast cancer determined to be:

• Confirmed HER2-positive : (ASCO CAP guidelines, 10/7/2013)

  • IHC 3+ based on circumferential membrane staining that is complete, intense
  • ISH positive based on:
  • Single probe average HER2 copy number ≥ 6 signals/cell
  • Dual probe HER2/CEP 17 ratio ≥ 2.0 with an average HER2 copy number ≥ 4.0 signals/cell
  • Dual probe HER2/CEP 17 ratio ≥ 2.0, with an average HER2 copy number of < 4.0 signals/cell
  • Dual probe HER2/CEP 17 ratio < 2.0 with the average HER2 copy number of ≥ 6.0 signals/cell
• any ER or PR receptor status
• LVEF assessment by echocardiogram within 30 days of initiation; EF of ≥ 55% considered normal.
• Normal troponin I level at baseline

• Blood counts must meet the following criteria:

  • ANC greater than or equal to 1500/mm3
  • Platelet count greater than or equal to 100,000/mm3
  • Hemoglobin greater than or equal to 10 g/dL
• Serum creatinine less than or equal 2.5 mg/100ml
• Adequate hepatic function by these criteria: total bilirubin must be less than or equal to 1.5 x the ULN for the lab unless the patient has a bilirubin elevation great than the ULN to 1.5 x ULN due to Gilbert's disease or similar syndrome involving slow conjugation of bilirubin; and alkaline phosphatase must be less than or equal to 2.5 x ULN for the lab; and AST must be less than or equal to 1.5 x ULN for the lab. Both alkaline phosphatase and AST may not both be greater than the ULN.
• Patients with AST or alkaline phosphatase > ULN are eligible for inclusion in the study if liver imaging (CT, MRI, PET-CT or PET scan) performed within 90 days prior to randomization does not demonstrate metastatic disease and the requirements are met as above
• Patients with alkaline phosphatase that is > ULN but less than or equal to 2.5 x ULN or unexplained bone pain are eligible for inclusion in the study if a bone scan, PET-CT scan, or PET scan performed within 90 days prior to randomization does not demonstrate metastatic disease.

Exclusion Criteria:

Patients with a history of decompensated congestive heart failure or an EF < 55% will be excluded

• Cardiac disease that would preclude the use of the drugs included in the above regimens. This includes but is not confined to:

• Active cardiac disease:
• angina pectoris requiring the use of anti-anginal medication;
• ventricular arrhythmias except for benign premature ventricular contractions controlled by medication;
• conduction abnormality requiring a pacemaker;
• supraventricular and nodal arrhythmias requiring a pacemaker or not controlled with medication; and
• clinically significant valvular disease
• symptomatic pericarditis
• pulmonary hypertension
• History of cardiac disease:
• myocardial infarction;
• congestive heart failure; or
• cardiomyopathy
