This is a single arm, phase 0 study to evaluate the safety and efficacy of PET-CT scans with FDG-labeled RBC in patients with breast cancer.
Cardiac ejection fraction can be calculated and monitored in breast cancer patients during chemotherapy using a FDG-RBC PET-CT scan. The purpose of this study is to determine if calculated cardiac ejection fraction shows high concordance with results from echocardiography.

Experimental: Cardiac Imaging - All Participants
Study agent: 2-deoxy-2-[18F]fluoro-D-glucose (FDG). Fluoro-D-glucose-positron Emission Tomography: Participants will undergo a PET-CT scan with Fluoro-D-glucose-labeled (FDG-labeled) red blood cells (RBCs) within 2 weeks of obtaining an echocardiogram prior to start of chemotherapy. A repeat FDG-RBC PET-CT scan will be completed within two weeks of obtaining their follow-up echocardiogram to determine post-therapy cardiac ejection fraction. If the participant has an echocardiogram obtained prior to completion of chemotherapy, an attempt will be made to obtain a FDG-RBC PET-CT scan within two weeks of the echocardiogram.
Diagnostic Test: Fluoro-D-glucose-positron Emission Tomography
2-deoxy-2-[18F]Fluoro-D-glucose-positron Emission Tomography (FDG-PET): within 2 weeks of obtaining first echocardiogram; within two weeks of obtaining follow-up echocardiogram.
Biological: 2-deoxy-2-[18F]fluoro-D-glucose (FDG)
2-deoxy-2-[18F]fluoro-D-glucose (FDG) labeled autologous human erythrocytes (RBCs): Approximately 10 mls of packed human erythrocytes are collected from the patient and labeled with ≈5-10 milliCuries of commercially available United States Pharmacopeia (USP)-grade FDG (≈5-10 picograms FDG) (Vendor: Cardinal Health) under sterile conditions in a Good Manufacturing Practice (GMP)-certified laboratory.
Synthesized RBCs: The cell suspension is manually infused via syringe through an indwelling peripheral venous catheter over the course of 1 minute, using an infusion method approved by the Moffitt Cancer Center (MCC) radiation safety officer.
Diagnostic Test: Echocardiogram
Echocardiogram: prior to start of chemotherapy; post-treatment regimen.
Other Name: Echocardiography
- Cardiac Ejection Fraction (EF) [ Time Frame: Up to 12 months ]Calculated cardiac ejection fraction (EF) with a low radiation dose FDG-RBC PET-computed tomography (CT) scan before and after neoadjuvant chemotherapy.
- Concordance Between FDG-RBC PET-CT and Echocardiogram [ Time Frame: Pre-treatment and Post-treatment, up to 12 months ]The concordance will be estimated by the use of Lin's method49 along with 95% confidence interval.
