Eligibility criteria:

        Inclusion Criteria:

        A woman will be eligible for inclusion in this study if she meets all of the following
        criteria:

          -  Age >18 to <70 years old.

          -  Has known ER and PR status

          -  Has HER2 nonamplified disease, confirmed by FISH

          -  Has known menopausal status (see Section 7.3 for criteria)

          -  Has operable, histologically confirmed, Stage I, IIA, IIB, or IIIA, IIIB, or IIIC
             invasive carcinoma of the breast. Bilateral synchronous breast cancer is allowable
             provided that 1 primary meets the inclusion criteria.

          -  Meets 1 of the 3 following criteria:

               -  T1-3N1-3M0 if ER positive or negative

               -  T2-3N0M0 if ER positive or negative

               -  T1N0M0 if ER and PR negative

          -  Has complete surgical resection of the primary breast tumor: either lumpectomy or
             mastectomy with sentinel lymph node biopsy or axillary dissection, with clear margins
             for both invasive and ductal carcinoma in situ (DCIS)

          -  Has had no prior chemotherapy unless >5 years ago

          -  Has an ECOG Performance Status (PS) 0-1

          -  Has laboratory values of: See protocol for specific details

          -  Has aspartate aminotransferase (AST) or alanine aminotransferase (ALT) and alkaline
             phosphatase (ALP) within the ranges shown below. In determining eligibility the more
             abnormal of the 2 values (AST or ALT) should be used. See protocol for specific
             details

          -  Has normal cardiac function as evidenced by a LVEF >50%, but WNL by institutional
             standard by multiple gated acquisition (MUGA) scan. An echocardiogram (ECHO) may be
             used if MUGA is not available, but the same modality must be used consistently
             throughout the study to evaluate LVEF. Ejection fraction as determined by ECHO must be
             WNL by institutional standard.

          -  Has no evidence of metastatic disease outside of breast by physical examination and
             chest x-ray. Other scans if done as needed by the patient (eg, bone scan; abdominal,
             chest CT; PET or PET/CT; ultrasound; or MRI should indicate no evidence of metastatic
             disease

          -  Has had baseline bilateral mammography

          -  It has been <84 days since the date of definitive surgery (eg, mastectomy or, in the
             case of a breast-sparing procedure, axillary dissection) with adequate wound healing,
             as determined by the Treating Physician

          -  Has a negative serum pregnancy test within 7 calendar days prior to registration
             (female patients of childbearing potential [not surgically sterilized and between
             menarche and 1 year postmenopause])

          -  If fertile, patient has agreed to use an acceptable method of birth control (barrier
             contraceptive only) to avoid pregnancy for the duration of the study and for a period
             of 3 months thereafter
