Eligibility

Age Range

Sex

FEMALE

Inclusion Criteria:

* Patient with postmenopausal bleeding
* Patient requiring hysteroscopy or hysterectomy
* No objection from the patient to participate in the study

Exclusion Criteria:

* Non-menopausal patient
* Patient under guardianship, curatorship or deprived of her freedom
* Patient with proven metastases on imaging
* Patient with a macroscopically suspicious cervix
* Patient presenting an ovarian cyst or an associated adnexal pathology
* Patient contraindicated for surgical treatment (therefore not eligible for pathological analysis)
* Patient who has already been treated with hormone therapy for breast cancer
* Patient who has already had surgery for this pathology, with a contributing anatomopathological result (we will therefore include patients who would not benefit from an operative hysteroscopy after performing a cornier® pipelle that does not allow a positive result)

Outcome Measures

Primary Outcomes

To evaluate the sensitivity of the HE4 marker in patients with postmenopausal bleeding in the diagnosis of endometrial cancer

The HE4 assays will be performed using the electrochemiluminescence (ECL) technique on Cobas Pro module E801, Roche Diagnostics. The HE4 assay is based on a sandwich-type electrochemiluminescence method. The HE4 assay with the Roche Diagnostics Elecsys reagent has been standardized against the Fujirebo Diagnostics HE4 EIA method. Positive/negative HE4 result for the estimation of the sensitivity of HE4 in the diagnosis of endometrial cancer. The commonly accepted threshold for ovarian cancer management of 140pmol/l in postmenopausal patients should be used. The gold standard for endometrial cancer is the pathological result (absence/presence of cancer) of the sample taken.

Time frame: Until the pathological results (About 10-15 days)

Secondary Outcomes

Assess other diagnostic parameters (specificity, PPV, NPV) of HE4

ROC curve for the HE4 marker in the diagnosis of endometrial cancer.

Time frame: Until the pathological results (About 10-15 days)

Establish the optimal threshold of HE4 for the diagnosis of endometrial cancer (use of an ROC curve)

Search for the threshold with the best specificity of HE4 in the diagnosis of endometrial cancer

Time frame: Until the pathological results (About 10-15 days)

Evaluate the diagnostic capabilities of CA125 alone and in combination with HE4, as well as the REM and REM-B algorithms for the diagnosis of endometrial cancer

Estimation of sensitivity, specificity, PPV and NPV in the diagnosis of endometrial cancer for the CA125 biomarker and the REM and REM B algorithms

Time frame: Until the pathological results (About 10-15 days)

Establish the existence of thresholds for HE4 and/or CA125 markers predictive of disease severity (FIGO stage)

Search for HE4 and CA125 marker thresholds to assess disease severity by FIGO stage

Time frame: Until the results of the extension assessment in the event of proven endometrial cancer (1 month)

Reassess the pathological threshold value of endometrial thickness on ultrasound

Search for the pathological threshold of endometrial thickness in the diagnosis of endometrial cancer

Time frame: Until the pathological results (About 10-15 days)

Assess the relationship between endometrial thickness on ultrasound and HE4 and CA125 marker values

Estimation of the relationship between CA125 and HE4 markers and endometrial thickness on ultrasound

Time frame: Until the pathological results (About 10-15 days)

To evaluate the diagnostic capabilities of HE4 and CA125 in subgroups of smoking patients and patients with renal failure

Estimation of sensitivity, specificity, PPV and NPV in the diagnosis of endometrial cancer for HE4 and CA125 in patients with active smoking and/or renal failure

Time frame: Until the pathological results (About 10-15 days)

Identify potential confounding factors associated with the value of the HE4 marker like treatments, comorbidities (renal insufficiency, high BMI) and others criteria that are collected in the medical files

Analyses of variables measured at inclusion that may influence the value of the HE4 marker.

Time frame: Until the pathological results (About 10-15 days)
