Details and patient eligibility

About

Through the investigators' Breast Care Center at the University of Michigan Comprehensive Cancer Center, the investigators treat approximately 75 patients per year with neoadjuvant chemotherapy. The majority of the remainder of patients with stage II and III disease undergo treatment with adjuvant chemotherapy either on a clinical protocol or as standard of care. There is a subset of women with ER positive disease who do not receive chemotherapy because of favorable tumor characteristics.

This tissue procurement protocol is designed to systematically collect tissue, urine and blood specimens on patients undergoing neoadjuvant systemic therapy or adjuvant chemotherapy, serially following treatment, and/or at the time of disease recurrence in order to investigate mechanisms underlying development of metastatic disease, to identify predictors of response and resistance to therapy, and to test potential new therapies for breast cancer using a combination of patient-derived xenograft creation and new microfluidic technologies.

Inclusion and exclusion criteria

Entry Criteria for patients receiving neoadjuvant or adjuvant therapy (groups 1 and 2)

Inclusion Criteria

All patients must have a primary invasive breast cancer with the primary tumor intact (T2-4, any N, any M). Inflammatory breast cancer is permitted.
For the neoadjuvant cohort (group 1), the patient's clinical plan includes neoadjuvant systemic therapy (chemotherapy, hormonal therapy, and/or biologic therapy) prior to surgery on the breast.
For the adjuvant cohort (group 2), the patient's clinical plan includes surgical resection of the primary breast mass followed by adjuvant chemotherapy (with or without endocrine therapy or biologic therapy such as trastuzumab).
Patients in the neoadjuvant cohort must have had mammography performed at the University of Michigan, OR outside film review prior to enrollment.
All patients are required to sign an informed consent document regarding the experimental purpose of the research biopsies and serum banking, in accordance with the University of Michigan IRB standards.

Exclusion Criteria - For the neoadjuvant cohort (group 1): Tumors diagnosed by excisional biopsy, or incisional biopsy that does not leave at least 2 cm of measurable disease by physical examination, mammography, or ultrasound (with the exception of inflammatory breast cancer)

For the adjuvant cohort (group 2): Tumors diagnosed by excisional or incisional biopsy and which are not likely to have at least 2 cm of residual tumor remaining

Patients must not have received any prior chemotherapy, hormonal therapy, or radiation therapy for their current breast cancer. Patients who received tamoxifen or other agents for prevention of breast cancer may be included.
Patients with another active systemic malignancy within the past year.

Entry Criteria for patients with newly diagnosed locoregional or distant disease recurrence (who did not enroll at the time of initial adjuvant or neoadjuvant chemotherapy) (group 3)

Inclusion Criteria

Patients must have been previously diagnosed with non-invasive or invasive breast cancer.
Patients must have been diagnosed with biopsy-proven recurrence of breast cancer at any site
All patients are required to sign an informed consent document regarding the experimental purpose of the research biopsies and serum banking, in accordance with the University of Michigan IRB standards.

Exclusion Criteria

Patients must not have received any chemotherapy, hormonal therapy, or radiation therapy for treatment of their recurrent breast cancer.
Patients must not have been diagnosed with another active systemic malignancy within the past year.
