Official title
Improving Detection and Outcomes in Patients With Metastatic Invasive Lobular Breast Cancer Through Novel F-18 FAPI PET Imaging
Overview
This study is a pilot clinical imaging trial of a prospective, head-to-head comparison of 18F-Fibroblast Activation Protein Inhibitor (FAPI)-74 PET/CT versus standard-of-care 18F-Fluorodeoxyglucose (FDG) PET/CT in 15 patients with metastatic invasive lobular breast cancer (ILC). Patients will undergo both 18F-FDG PET/CT and 18F-FAPI-74 PET/CT within a 2-week period (14 days + 7 days) to compare lesions, tumor detection rates, and PET lesion intensity, as well as to assess the clinical value of the PET scans from the treating physician's and the patient's perspective.
Interventions
- Drug 18F-FAPI-74
FAPI scans will be performed as hybrid PET/CT examinations for attenuation correction and lesion localization. Each patient will be injected intravenously with 7 mCi +/- 2 mCi of 18F-FAPI-74 followed by a 20-minute (+/-10 min) uptake period. - Drug 18F-FDG
FDG PET/CT will be performed per standard-of-care protocol at Mount Sinai Hospital. Patients will fast for at least 6 hours before FDG administration and plasma glucose levels will be checked to ensure \< 200 mg/dL. Each patient will be injected intravenously with 15 mCi +/- 20% of 18F-FDG. - Procedure PET/CT
FAPI PET/CT images will be acquired from the top of skull to mid-thigh. FDG PET/CT images will be acquired from the skull base to mid-thigh after a 60-min uptake period. Outside FDG PET/CT performed at another institutional can be accepted, if image quality and acquisition is comparable to standard-of-care protocol at Mount Sinai Hospital.
Primary outcome measures
- Proportion of lesions detected by 18F-FAPI-74 PET/CT [Time frame: End of study, at 1 month]
Secondary outcome measures (7)
- Proportion of lesions detected by 18F-FDG PET/CT but not by 18F-FAPI-74 PET/CT [Time frame: End of study, at 1 month]
- Proportion of concordant lesions detected by both 18F-FAPI-74 PET/CT and 18F-FDG PET/CT [Time frame: End of study, at 1 month]
- Tumor detection rate [Time frame: End of study, at 1 month]
- SUVmax of the hottest lesion (lesion with highest SUVmax) on 18F-FAPI-74 PET/CT compared to 18F-FDG PET/CT and mean SUVmax across all lesions [Time frame: End of study, at 1 month]
- Tumor-to-background ratio (TBR) [Time frame: End of study, at 1 month]
- Number of participants with change in therapeutic management decisions [Time frame: End of study, at 1 month]
- Change in disease status assessment [Time frame: End of study, at 1 month]
