Diagnostic Accuracy and Safety Study of FES PET/CT in Assessment of ER Status of Recurrent or Metastatic Breast Cancer

Brief Summary:
The standard diagnostic workup for recurrent or metastatic breast cancer includes biopsy and determination of tumor estrogen status according to National Comprehensive Cancer Network and European Society for Medical Oncology. Immunohistochemistry (IHC) is currently the most commonly used method for determining ER status. A investigational imaging tracer named 16-alpha-[18F]-fluoro-17-beta-estradiol, or [18F]fluoroestradiol ([18F]FES) acts similarly in vivo to estradiol and binds to estrogen receptors (ERs). Previous studies in human have shown the efficacy of [18F]FES PET in detecting ER positive breast cancer without any observed toxicity. The investigators hypothesized that [18F]FES PET imaging can noninvasively assess ER status in recurrent or metastatic breast cancer lesion . In this study, a positive and negative percent agreement between IHC and [18F]FES will be determined.

Arm Intervention/treatment
Experimental: [18F]fluoroestradiol (FES)
The injectable radioactive dose of 111-222 megabecquerel. One single IV injection over 1-2 min. [18F]FES PET/CT for imaging.
Drug: [18F]fluoroestradiol (FES)
[18F]FES PET/CT will be performed 90 min (± 10 min) after administration of [18F]FES. Patients will undergo core needle biopsy or surgery within 15 days after [18F]FES PET; or patients will undergo core needle biopsy within 30 days before [18F]FES PET. Experienced pathologists will determine metastatic/recurrent disease, and tumor histology including IHC. Patient will undergo surgery, radiation therapy or systemic therapy according to the results of staging workup, histology and biomarkers.

Primary Outcome Measures :
  1. lesion-level positive and negative percent agreement between qualitative [18F]FES PET interpretation and reference IHC testing [ Time Frame: up to 3 years ]

    3. Patients had histologically confirmed invasive primary breast carcinoma and the documented results of histology are available.
    4. Patients are scheduled to undergo core needle biopsy or surgery for histological confirmation and determination of ER status of recurrent or distant metastatic cancer within 15 days after [18F]FES PET; or patients already underwent core needle biopsy of recurrent or distant metastatic cancer within 30 days before [18F]FES PET and biopsy specimens are available for determination of ER status.
    5. Discontinuation of selective ER blocking agents including tamoxifen or fulvestrant for at least 60 days prior to [18F]FES PET
    6. Eastern Cooperative Oncology Group (ECOG) performance status of ≤2

Exclusion Criteria:

  • A patient will be excluded from this study if the patient does not full fulfill the inclusion criteria, or if any of the following conditions are observed

    1. Patient or patient's legally acceptable representative do not provide written informed consent
    2. The recurrent or metastatic lesion scheduled to undergo biopsy is located in breast, liver, ovary, uterus, or bone
    3. Female patient is pregnant or nursing. Exclusion of the possibility of pregnancy is made by one of the following: 1) woman is physiologically post menopausal (cessation of menses for more than 2 years), 2) woman is surgically sterile (has had a documented bilateral oophorectomy and/or documented hysterectomy, or 3) if the woman is of childbearing potential, a urine pregnancy test performed within 24 hours immediately prior to administration of [18F]FES has to be negative and the women is advised to apply contraceptive measures during her participation in this study
    4. Adjuvant chemotherapy within 3 weeks prior to [18F]FES PET.
    5. Radiation therapy or immuno/biologic therapy is scheduled to be given to patient before the histologic confirmation by biopsy or [18F]FES PET.
    6. Concurrent severe and/or uncontrolled and/or unstable medical disease other than cancer (e.g. congestive heart failure, acute myocardial infarction, severe pulmonary disease, chronic renal or hepatic disease which could compromise participation in the study) in the judgment of the investigator.
    7. Patient is a relative of the investigator, student of the investigator or otherwise dependent
    8. Patient has any other condition or personal circumstances that, in the judgment of the investigator, might interfere with the collection of complete data
    9. Patient has been involved in an investigative, radioactive research procedure within 7 days prior to registration
