F-FES) is an in vivo specific imaging agent for estrogen receptor (ER). We investigated the concordance between tumor ER status as determined by FES-PET and in vitro immunohistochemical assays. Methods:
18
F-FES was prepared by ourselves. Twenty-six patients were enrolled (17 primary and 9 metastatic/recurrent). Patients underwent both
18
F-FES and
18
F-FDG PET/CT. Results: We found good overall agreemen
t (96.15%) between in vitro ER assays and FES-PET. The ER status diagnosis sensitivity of
18
F-FES was 93.33% and the specificity was 100% when using cut-off value of SUV
max
≥1.5. There was a positive correlation between in vitro ER
PR assays and the SUV
max
of
18
F-FES while in vitro HER-2/neu assays correlatived negatively with
18
F-FES SUV
max
. Conclusion: These results suggested
18
F-FES may be useful for studying the ER expression of all malignant lesions in patients with breast cancer and guiding individual therapy.
