Learning Curve for Ultrasound Assessment of Myometrial Infiltration in Endometrial Cancer Visualizing Videoclips: Potential Implications for Training.

Background: Diagnostic accuracy for estimating myometrial infiltration by ultrasound in endometrial cancer requires experience. The objective of this study is to determine the learning curve (LC) for assessing myometrial infiltration in cases of endometrial cancer using transvaginal ultrasound (TVS).

Methods: Five trainees (one staff radiologist and four fourth-year OB/GYN residents) participated in this study.

Risk of endometrial cancer and endometrial hyperplasia with atypia in asymptomatic postmenopausal women with endometrial thickness ≥11 mm: A systematic review and meta-analysis.

Purpose: To evaluate the risk of endometrial cancer and/or endometrial hyperplasia with atypia in asymptomatic postmenopausal women with endometrial thickness ≥ 11 mm.

Methods: Systematic review of literature using database search (PubMed and Web of Science) of articles published between January 1990 and December 2016 evaluating the correlation between endometrial thickness as measured by transvaginal ultrasound (double layer) and histopathological findings in asymptomatic postmenopausal women, using the following terms: "endometrial thickness," "postmenopausal," "postmenopause," and "asymptomatic." Inclusion criteria were prospective or retrospective studies of more than 150 cases that provided information on endometrial thickness and its correlation with histopathological data.
