64 Cu-DOTA-alendronate PET Imaging in Localizing and Characterizing Breast Calcifications in Participants Before Undergoing Mastectomy
This early phase I pilot trial studies how well 64Cu-DOTA-alendronate positron emission tomography (PET) imaging work in localizing and characterizing breast calcifications (small calcium deposits) in participants before undergoing mastectomy. Diagnostic procedures, such 64Cu-DOTA-alendronate PET, may detect calcification and help doctors predict cancer associated calcification within breast tissue.
PRIMARY OBJECTIVES:
I. To evaluate the uptake (maximum standardized uptake value [SUVmax]) of 64Cu-DOTA-alendronate in female patients with biopsy-proven malignant breast calcifications.
SECONDARY OBJECTIVES:
I. To compare uptake of 64Cu-DOTA-alendronate on PET -computed tomography (CT) with histology after mastectomy.
OUTLINE: This is a dose-escalation study of 64Cu-DOTA-alendronate.
Participants receive 64Cu-DOTA-alendronate intravenously (IV) and undergo PET/CT imaging 60 minutes after injection. Participants with sufficient levels of residual radioactivity may undergo repeat imaging on day 1 as determined by the study team.
After completion of study , participants are followed up for 7 days.
