NCT05613270

Brief Summary

18F-fluoroestradiol (FES) is radioactive labeled estradiol, developed for in vivo visualization of estrogen receptor (ER) using positron emission tomography (PET). In this prospective study, 18F-FES PET/CT will be used to evaluate ER activity of metastatic disease and their potential sensitivity to endocrine therapy in ER-positive breast cancer.

Outcome Measures

Primary Outcomes (3)

  • Standardized uptake value of 18F-FES in BC

    The max standard uptake value (SUVmax) was measured in the breast cancer lesions on 18F-FES PET/CT.

    through study completion, an average of 1 year

  • Lesions detected by 18F-FES PET/CT

    The number of target lesions was calculated by 18F-FES PET/CT.

    through study completion, an average of 1 year

  • Compared with 18F-FDG PET/CT

    The number of lesions detected by 18F-FES PET/CT was compared with 18F-FDG PET/CT.

    through study completion, an average of 1 year

Secondary Outcomes (1)

  • Overall survival

    3 years

Study Arms (1)

18F-FES PET/CT

EXPERIMENTAL

Inject 18F-FES and then perform PET/CT scan.

Diagnostic Test: 18F-FES PET/CT scan

Interventions

18F-FES PET/CT scanDIAGNOSTIC_TEST

Patients with suspected metastatic ER-positive breast cancer underwent 18F-FES PET/CT after an injection of 185-222 MBq (5-6 mCi) 18F-FES to image lesions of metastatic breast cancer.
