Investigating women with postmenopausal bleeding: The utility of endometrial thickness in transvaginal ultrasound.

Twenty point nine percent of women with PMB had a malignancy. With an upper limit of 4 mm in ET on ultrasound, malignancy was present in 22% of participants. [Correction added on 10 July 2020, after first online publication: percentage of women with PMB that had a malignancy has been amended to twenty point nine percent.] CONCLUSIONS: A limit of 3 mm for ET in PMB, along with office endometrial biopsy, should be considered to ensure timely diagnoses.
