Breast Cancer Clinical Trial
FDG PET and DCE-MRI in Predicting Response to Treatment in Patients With Breast Cancer
This clinical trial studies fludeoxyglucose F 18 (FDG) positron emission tomography (PET) and dynamic contrast-enhanced (DCE)-magnetic resonance imaging (MRI) in predicting response to treatment in patients with breast cancer. Comparing results of diagnostic procedures done before, during, and after chemotherapy may help doctors predict a patient's response to treatment and help plan the best treatment.
I. To determine whether detailed kinetic analysis of FDG PET and magnetic resonance (MR) imaging studies for measures of tumor metabolism and blood perfusion can predict response and outcome for breast cancer patients undergoing neo-adjuvant therapy.
II. To compare the in vivo tumor biology associated with responsive and resistant tumors as measured by kinetic changes in FDG PET and MR imaging parameters to tumor subtypes analyzed from assay of pre-therapy biopsy and post-therapy surgical tissue.
Patients undergo FDG PET and DCE-MRI 1-2 weeks before prior to chemotherapy initiation, between 1-12 weeks after initiation of the first course of chemotherapy, and after the completion of chemotherapy (within 4 weeks prior to surgery).
Pathologically confirmed breast cancer, determined to be a candidate for primary systemic (neoadjuvant) therapy and for surgical resection of residual primary tumor following completion of neoadjuvant therapy
Primary tumor 2.0 cm or greater, and/or clinical evidence of axillary disease (palpable N1 or N2 or biopsy proven)
No obvious contraindications for primary chemotherapy
Able to lie still for PET and MRI scanning
Able to understand and willing to sign a written informed consent document and a Health Insurance Portability and Accountability Act (HIPAA) authorization in accordance with institutional guidelines
Serious systemic illness other than breast cancer
Contraindication to MRI or history of adverse reaction to gadolinium
Evidence of distant disease outside of regional lymph nodes
Poorly controlled diabetes mellitus (fasting blood glucose > 200)
Prior systemic cancer therapy
