Pilot Study of Zirconium-89 Bevacizumab Positron Emission Tomography for Imaging Angiogenesis in Patients With Inflammatory Breast Carcinoma Receiving Preoperative Chemotherapy

89Zr-bevacizumab is a newly developed radiotracer. Radiotracers are compounds or drugs that are attached to small amounts of a radioactive substance. The amount of the compound or drug in a radiotracer is also very small. Radiotracers are used to make images of processes that are happening in the body, but they do not affect how the body works. 89Zr-bevacizumab is made up of the drug bevacizumab and the radioactive substance zirconium-89 (89Zr). 89Zr-bevacizumab is used for an imaging procedure called positron emission tomography/computed tomography (PET/CT). 89Zr-bevacizumab-PET/CT will be performed in this study at baseline, after 2 cycles of preoperative chemotherapy and at the completion of chemotherapy.

FDG-PET/CT scan: Pictures of your organs will be taken using a PET (Positron Emission Tomography) scanner. At the same time, a CT (computed tomography) scan will be performed. FDG, a radioactive substance similar to glucose (or sugar), will be injected into your vein using a needle prior to performing the PET/CT scan. After the injection, you will be asked to sit quietly for one hour to let the FDG absorb into the body. After this hour, you will be asked to lie flat on your back for up to 50 minutes while the PET and CT images are being taken. This FDG-PET/CT scan is part of regular cancer care. If you have had this test within 14 days of study enrollment, you may or may not have to have this test repeated.

• MRI Scan: MRI (Magnetic Resonance Imaging) scans of the breast will be taken. You will receive an injection of a dye before the MRI. You will be asked to lie flat on your back in the scanner for up to 30 minutes for pictures to be taken. This MRI scan is part of regular cancer care. If you have had this test within 14 days of study enrollment , you may or may not have to have this test repeated.

Tumor biopsies: Prior to starting your treatment, a radiologist will use breast MRI or ultrasound imaging to localize an area of your tumor in the breast for a research biopsy. The biopsy procedure is done in an outpatient setting using a done using a needle to obtain tissue. A local anesthetic will be given to minimize any pain; however, after the procedure you can expect some discomfort and possible bruising. This biopsy is part of research.
