About this trial

This is an interventional diagnostic trial for Deep Fibromatosis/Desmoid Tumor focused on measuring desmoid, FES-PET, aggressive fibromatosis

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patients with biopsy-proven extra-abdominal desmoid tumors
  • Not currently on estrogen medication for birth control, menopause, or other reason
  • No anti-estrogen therapy for desmoid tumor within the past 6 months
  • Both sporadic desmoid tumors and those associated with familial adenomatous polyposis (FAP) syndromes will be included

Exclusion Criteria:

  • Pregnancy or nursing patients
  • Patients who do not wish to participate

Sites / Locations

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Diagnostic (18F-FES PET/CT)

Arm Description

Patients undergo 18F-FES PET/CT imaging over 30 minutes.

Outcomes

Primary Outcome Measures

Standard uptake value (SUV) measured as percent injected dose per cc
Data will be summarized graphically and numerically. Continuous variables (e.g. SUV) will be summarized using the mean, standard deviation, and a 5 number percentile summary set (minimum, p25, p50, p75, and maximum). The Spearman correlation statistic will be used to estimate the magnitude of a linear association between SUV and IHC measures. Ninety-five percent confidence intervals will be calculated for all point estimates.

Secondary Outcome Measures

IHC staining intensity in tissue samples
IHC staining intensity measured on an ordinal scale or dichotomized as positive or negative. Data will be summarized graphically and numerically. Categorical measures (e.g., IHC) will be summarized in frequency tables. The Spearman correlation statistic will be used to estimate the magnitude of a linear association between SUV and IHC measures. Ninety-five percent confidence intervals will be calculated for all point estimates.

5. Study Description

Brief Summary
This pilot clinical trial studies fluorine (F)-18 16 alpha-fluoroestradiol (18F-FES) positron emission tomography (PET)/computed tomography (CT) in imaging patients with desmoid tumors. 18F-FES binds to estrogen receptors, which are present on desmoid tumors, and gives off radiation that may be detected by PET and CT scans. The PET/CT scan forms an image that may show where tumor cells with estrogen receptors can be found in the body.
Detailed Description
PRIMARY OBJECTIVES: I. Establish the avidity of desmoid tumors on 18F-FES PET/CT imaging. II. Correlate 18F-FES PET avidity with degree of estrogen receptor (ER) expression by immunohistochemistry (IHC). OUTLINE: Patients undergo 18F-FES PET/CT imaging over 30 minutes. After completion of study, patients are followed up for 30 days.
