Brief Summary:
The majority pf breast cancers present as ER-positive, many of which are able to be targeted with multiple hormonal therapies. Altering ER-negative tumors to increase ER expression has the potential to benefit patients by making hormonal therapies a therapeutic option and possibly improving their overall prognosis.

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: trastuzumab (Herceptin®) Phase 1 Phase 2

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 1 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Evaluation of the Use of Trastuzumab to Induce Increased ER Expression in ER-Negative/Low, Her-2/Neu Positive Breast Cancer

Arm Intervention/treatment
Experimental: Treatment arm Drug: trastuzumab (Herceptin®)
About 1 week (4 - 7 days) before scheduled breast surgery, consisting of lumpectomy or mastectomy, subjects will receive a dose of trastuzumab (Herceptin®). Trastuzumab will be given through an IV or port for approximately 90 minutes. During this time, subjects will be closely monitored by a chemotherapy nurse to make sure that subjects do not have a reaction to the medication. It is possible that the infusion of the medication will need to be slowed down, in which case, the time for the infusion will be longer than 90 minutes. The one dose of the trastuzumab drug will be provided by the study (not billed to insurance), but the charges to administer the drug will be billed to subjects or subjects health insurance.

Primary Outcome Measures :
  1. Standard Immunohistochemistry and Allred Scores Were to be Used to Measure the Estrogen Receptor (ER) Response Rate in Patients With ER-negative/Low, and Human Epidermal Growth Factor Receptor 2 (HER2)/Neu-positive Breast Cancer. [ Time Frame: 90 days ]
