Positron Emission Tomography Imaging Using Copper Cu 64 TP3805 in Patients With Breast Cancer

OBJECTIVES: I. The study's primary goal is to assess the ability of Cu-64-TP3805 (copper Cu 64 TP3805) to detect primary breast lesions as determined by the F-18-FDG (fludeoxyglucose F 18) scan. II. The study's second goal is to determine the ability of Cu-64-TP3805 to detect primary breast lesions as determined by histology (sensitivity). III. The study's third goal is to determine the ability of Cu-64-TP3805 to detect metastatic lesions as identified by the F-18-FDG whole-body scan. OUTLINE: This is a dose-finding 2-stage study. STAGE I: Patients with a positive biopsy and abnormal (positive) fludeoxyglucose F18-labeled PET whole-body scan undergo a whole-body copper Cu 64 TP3805-labeled PET scan. STAGE II: Patients with a positive biopsy, but no fludeoxyglucose F18 scan undergo a breast fludeoxyglucose F18-labeled PEM scan followed by a breast copper Cu 64 TP3805-labeled PEM scan.
