Brief Summary
The main goal of this study is to characterize whether the results of the Oncotype DX® assay affect the physician's treatment recommendations for the adjuvant treatment of women with ER-positive (ER+), early breast cancer (EBC) with 1-3 positive lymph nodes who are potential candidates for chemotherapy, but for whom the benefits of chemotherapy may be uncertain.

Study Arms (1)
Early stage breast cancer
EXPERIMENTALWomen with node positive (1-3 nodes), ER positive breast cancer who are receiving (or will receive) endocrine therapy, and who are candidates for chemotherapy. Study subjects will have ONCOTYPE Dx assay performed on their breast tumors, and will complete study questionnaires.
Interventions
1. Physician pre-assay questionnaire 2. Patient pre-assay questionnaire 3. Oncotype DX® Assay 4. Physician post- assay questionnaire 5. Patient post-assay questionnaire
Eligibility Criteria
You may qualify if:
- Patients must have undergone surgical treatment for breast cancer with adequate evaluation of lymph node status with a sentinel lymph node procedure or full axillary dissection, with positive involvement of 1-3 axillary lymph nodes as confirmed by histologic examination.
- ECOG performance status 0 or 1
- Patient must be a candidate for treatment of their cancer with systemic chemotherapy in addition to hormonal therapy
- Eligible Staging Criteria: T1-3 N1 M0
- Breast tumor must undergo central pathology review at GHI and must be found adequate for the Oncotype DX assay.
- Breast tumor must be estrogen-receptor positive and HER2 positive (IHC/FISH) as per institutional guidelines
You may not qualify if:
- Patient has a prior history of breast cancer in the same breast
- Patient as been newly diagnosed with more than one operable primary breast tumor
- Patient has multi-centric tumors (note: patients with multi-focal tumors may be included)
- Patient has known metastatic breast cancer
- Patient has \<2mm invasive tumor as assessed by local pathologist
- Patient has received any kind of neoadjuvant treatment
- Presence of clinical factors rendering the patient a non-viable candidate for adjuvant chemotherapy
- Presence of a current medical condition that would interfere with patient's ability to consent and participate in this study
