Abstract

Objective To determine the use of the transvaginal ultrasound (TVUS) in postmenopausal women with type II endometrial cancer.

Methods/Materials A retrospective review was conducted for 173 women with pathology proven type II endometrial cancer at a single institution. Those who underwent preoperative TVUS were included, and the following data were obtained: endometrial stripe (EMS) measurement, uterine and/or adnexal findings, and uterine size/volume. Clinicopathologic factors were abstracted. Descriptive and regression analyses were performed.

Results Fifty-eight women comprised the cohort, and the median age was 66.5 years (50–85 years). The most commonly reported symptom was postmenopausal bleeding in 53 patients (91.4%). The EMS was reported as thin (⩽5mm) or indistinct in 16 patients (27.5%). Approximately 60% of patients had 1 or more ultrasound abnormalities: intracavitary mass (31%), intracavitary fluid (12.1%), myometrial lesion (31.03%), and adnexal mass (12.1%). Poorly differentiated endometrioid cancer (53.45%) represented the predominant histology. Of the 16 (27.5%) women with a thin/indistinct EMS, 5 women (8.6%) did not have any abnormal ultrasound findings whatsoever.

Conclusions Women with type II endometrial cancer had a thin/indistinct EMS on TVUS in approximately 25% of cases. Lack of any ultrasound abnormality, including a thickened EMS, was noted in approximately 10% of patients. The use of TVUS, which has been of value in type I cancer, is limited in type II endometrial cancer. Therefore, endometrial sampling should be included in the evaluation of all women with postmenopausal bleeding, regardless of EMS thickness.
