Breast Cancer, Cancer of Breast, Breast Neoplasms
About this trial
This is an interventional treatment trial for Breast Cancer
Eligibility Criteria
Inclusion Criteria:
- Newly diagnosed histologically or cytologically confirmed operable invasive breast cancer defined as cT1 or T2, N0-1, and M0.
- Disease must be ER+ and HER2-.
- Ki67 score/proliferative index ≤ 30% or low to intermediate mitotic index
- Measurable disease defined as lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) by ultrasound or mammogram.
- 70 years of age or older.
- ECOG performance status ≤ 3
- Able to understand and willing to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).
Exclusion Criteria:
- Prior surgery for this cancer
- A history of other malignancy ≤ 5 years previous which would preclude endocrine treatment of their cancer.
- Currently receiving any other investigational agents.
- A history of allergic reactions attributed to compounds of similar chemical or biologic composition to any of the agents used in the study.
- Uncontrolled intercurrent illness as determined by their treating physician which would limit compliance with study requirements.
- Known HIV-positivity on combination antiretroviral therapy because of the potential for pharmacokinetic interactions with endocrine therapies. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated.

Arms of the Study
Arm 1
Experimental
Endocrine therapy alone
Neoadjuvant endocrine therapy will be given at the discretion of the treating physician as directed by the package insert and could include the following: goserelin, anastrozole, letrozole, exemestane, fulvestrant, or tamoxifen Frequency of office visits will be decided by the treating physician but must occur no less frequently than every 3 to 6 months for tumor assessment After 6 months and after 12 months, patients will be assessed; patients who progress will have standard care recommended , and at any point a patient can opt to receive standard care even if she has not progressed on neoadjuvant endocrine therapy Information on quality of life will be collected at baseline, Year 1, and Year 2 by the FACT-B questionnaire Archival tissue will be collected and sent to Genomic Health for analysis using the Oncotype DX assay. The Recurrence Score predicts chemotherapy benefit and indicates the 10-year risk of recurrence (will not be used to determine treatment)
