Assessment of Performance of [18F]-FES for Endometriosis Diagnosis (ENDOTEP)

September 13, 2018 updated by: University Hospital, Angers

Evaluation Des Performances de la Tomographie Par Emission de Positons Avec la 16α-[18F]Fluoro-17β-estradiol ([18F]-FES) Pour le Diagnostic de l'Endometriose

Endometriosis is a benign chronic disease responsible for infertility and pelvic pain. One of the main problem of endometriosis is the significant delay of diagnosis.This delay has significant consequences for patients. Currently the definitive diagnosis of endometriosis and the evaluation of its lesional extension require performing laparoscopy and a histological analysis of biopsy and pathologic areas. Lesions of endometriosis whose development and growth are estrogen-dependent, express estrogen receptor (ER). [18F]FES (16α-[18F]Fluoro-17β-estradiol) is an analog of estrogen, used in positron emission tomography (PET), and a specific tracer of ER. We propose to evaluate the performance of this functional imaging as a diagnostic tool for endometriosis.

The aim of this multicenter, prospective, open study is to assess sensitivity of PET with [18F] -FES for diagnosing endometriosis compared to the gold standard (histological confirmation on biopsy or excision of lesions performed during laparoscopy) in women care for suspected endometriosis and for whom laparoscopy is already scheduled.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
sensitivity of PET with [18F] -FES for diagnosing endometriosis defined by the ability of this diagnostic exam to give a positive result when endometriosis is present
Time Frame: Within 3 months after inclusion when laparoscopy is already scheduled.

PET with [18F]-FES considered positive if it allows to identify at least one hyperfixation area in a physiologically area not fixing tracer or not corresponding to a physiological removal area tracer.

PET results will be correlated with The results of PET with [18F] -FES will be correlated with histology results of at least one of the biopsies performed at laparoscopy.

Within 3 months after inclusion when laparoscopy is already scheduled.
