Evaluation of ultrasound endometrial stripe thickness in uterine serous carcinoma

Abstract

Uterine serous carcinoma (USC) is a rare type of endometrial cancer representing less than 10% of uterine cancers, but contributes to up to 50% of the mortality. USC can occur in the setting of a thin, atrophic endometrium. National guidelines support the use of transvaginal ultrasound as one option for initial triage in the evaluation of a woman with postmenopausal bleeding. If the endometrial stripe (EMS) is ≤4 mm, biopsy can be avoided if no further bleeding occurs. We sought out to further investigate the EMS thickness in USC in order to assess the reliability of the current guidelines in this cancer.
