HE4 in the Diagnostic Approach of Endometrial Cancer in Patients With Postmenopausal Bleeding

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)
