Brief Summary
This phase II trial studies how well genetic testing works in predicting tumor response in patients with stage I-III HER2 negative invasive breast cancer. Genetic testing is a procedure that tests tumor samples to learn if certain genes are activated (turned on) in the tumor and if the activation of these genes may predict if the tumor will be sensitive or resistant to routine breast cancer treatments, such as chemotherapy or hormonal therapy.

Conditions
Outcome Measures
Primary Outcomes (1)
Feasibility defined as the ability to classify patients into 1 of 4 cohorts
The study will use the methods of Thall et al. to monitor the ability to classify patients into 1 of 4 groups (success rate) throughout the trial. Will use summary statistics to describe the demographic and clinical characteristics of patients overall and within each subgroup (Groups A-D).
Up to 5 years
Secondary Outcomes (4)
Disease-free survival (DFS)
Time between diagnostic tumor biopsy and the first failure event, assessed at 3 and 5 years
Frequency of tumors
Up to 5 years
Concordance of genomic analysis with immunohistochemistry (IHC)
Up to 5 years
Indeterminate Results
Up to 5 years
Study Arms (1)
Diagnostic (biopsy, surgery, genetic testing)
EXPERIMENTALPatients undergo biopsy or surgery to obtain tumor sample for genetic testing. Patients are then assigned to 4 treatment cohorts as determined by genetic test results.
Interventions
Undergo tumor biopsy
Undergo genetic testing
Eligibility Criteria
You may qualify if:
- The patient can undergo biopsy or surgery of a primary tumor site for suspected or proven invasive breast cancer of clinical stage I to III; stage IV patients will be allowed and included in the feasibility assessment, but will not be included in outcomes analysis for secondary objectives
- The clinical or radiologic primary tumor size is at least 1 cm diameter
You may not qualify if:
- The patient has proven HER2-positive breast cancer, defined as a pathology report of amplification of the gene or 3+ score for immunohistochemical staining
- The patient has received prior systemic therapy or radiation therapy for breast cancer
- The patient has a prior history of invasive or metastatic cancer within 5 years of diagnosis of breast cancer, excluding squamous cell or basal cell carcinoma of the skin
- The patient had prior excisional biopsy of the primary invasive breast cancer
- There is hematoma or biopsy site changes that obscure the primary tumor
- Patients deemed medically ineligible for any adjuvant or neoadjuvant therapy. Patients with ER-positive (+) tumors deemed medically eligible for hormonal therapy, but not chemotherapy will be considered eligible for this protocol. Patients with ER-negative (-) tumors who are not candidates for adjuvant anthracycline based chemotherapy will be considered ineligible for this protocol. Patients who undergo biopsy and are later found to be ineligible for adjuvant therapy will be assessed for the primary objective, but will be excluded from the secondary objectives
