About this study

Patients with known or suspected primary or metastatic breast cancer with one lesion that is 1.0 cm in diameter or greater may be eligible for this study. Patients may participate in this study if they are at least 18 years of age. Up to 40 evaluable subjects will participate in a single imaging cohort. Patients will be stratified for analysis by breast cancer subtype with prioritization to recruit at least 10 estrogen-receptor-expressing (ER+) and 10 triple-negative breast cancers (TNBC). Participants may be treatment naïve or have received up to 3 weeks of treatment at the time of the \[18F\]F-Gln PET/CT scan. This is an observational study; \[18F\]F-GLN PET/CT will not be used to direct treatment decisions. While patients and referring physicians will not be blinded to the \[18F\]F-GLN PET/CT results, treatment decisions are made by the treating physicians based upon clinical criteria. \[18F\]F-GLN PET/CT imaging sessions will include an injection of \[18F\]F-GLN. Metabolism data will be collected. Pilot data will be collected to evaluate image quality and collect preliminary information on the uptake of \[18F\]F-GLN in breast cancer. Uptake measures will be compared to tumor markers of glutamine metabolism, when tissue is available. The safety of \[18F\]F-GLN will also be evaluated in all subjects.
