Endometrial Cancer Screening in High-risk Populations

Endometrial cancer is one of the most common malignancies of the reproductive system. The incidence of endometrial cancer has increased in recent years. No effective, low-cost screening method for populations at high risk exists. The traditional methods of endometrial cancer screening and diagnosis (segmented scraping and hysteroscopic biopsy) are invasive examinations with high medical costs. It is urgent to establish a reasonable, effective, economical, and non-invasive endometrial cancer screening strategy. This study aims to evaluate the effectiveness and feasibility of transvaginal ultrasound and microscale endometrial sampling biopsy in screening for endometrial precancerous lesions and endometrial cancer among high-risk populations in China, and to conduct cost-effectiveness analysis of different screening strategy, ultimately guiding the development of screening strategies that are suitable for high-risk populations in China.
