Development of an In Vivo Cell Proliferation Marker for PET Assessment of Chemotherapeutic Response in Cancer
Description
Brief Summary
This phase I trial studies the side effects of positron emission tomography (PET)/computed
tomography (CT) in evaluating response to chemotherapy 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.
Detailed Description
I. Study fludeoxyglucose [18F]
2'-fluoro-5-methyl-1-beta-D-arabinofuranosyluracil-clevudine (FMAU) (fluorine F 18-clevudine
) in 10 patients with known breast cancer to obtain data on safety, circulating metabolite,
tumor imaging feasibility, and radiation dosimetry. II. Assess the potential utility of
FMAU-PET in the imaging evaluation of chemotherapeutic response in 15 patients with breast
cancer. OUTLINE: Patients receive fluorine F18-clevudine intravenously (IV) over 1 minute and
then undergo PET/CT scan at baseline. Patients with human epidermal growth factor receptor 2
positive (HER2+) breast cancer also undergo fluorine F 18-clevudine PET/CT scan 2-3 weeks
after the first course of treatment and after completion of treatment. After completion of
study treatment, patients are followed up at 24 hours.
