Microscopic pathologic response, defined as no evidence of microscopic invasive tumor present at primary tumor site in the surgical specimen, as opposed to results "other than pathologic complete response (pCR)" [ Time Frame: At time of surgery ] [ Designated as safety issue: No ]
The primary clinical endpoint is dichotomous (yes/no). Associations with pathologic response will be estimated using logistic regression.

  • Percent change in tumor perfusion [ Time Frame: Baseline to up to 12 weeks (mid-therapy) ] [ Designated as safety issue: No ]
    Relationships between imaging variables and gene expression measured at pre-therapy will be examined by linear regression models.
  • Percent change in tumor metabolism [ Time Frame: Baseline to up to 12 weeks (mid-therapy) ] [ Designated as safety issue: No ]
    Relationships between imaging variables and gene expression measured at pre-therapy will be examined by linear regression models.
  • Time from surgery to breast cancer recurrence or death [ Time Frame: From surgery to breast cancer recurrence or death, assessed up to 5 years ] [ Designated as safety issue: No ]
    Will be examined using Cox proportional hazards regression.

FDG PET and DCE-MRI in Predicting Response to Treatment in Patients With Breast Cancer
Quantitative Dynamic PET and MRI and Breast Cancer Therapy

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.

PRIMARY OBJECTIVES:

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.

OUTLINE:

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).
