Abstract:

Women with Lynch syndrome have a life-long risk of endometrial cancer and ovarian cancer. Endometrial cancer or ovarian cancer can be the first malignant tumor or the second primary malignant tumor in patients with Lynch syndrome. The main type of endometrial cancer associated with Lynch syndrome is endometrioid adenocarcinoma. In recent years, there have been few screening studies on endometrial cancer and ovarian cancer related to Lynch syndrome, mainly through outpatient endometrial biopsy, microsatellite high instability (MSI-H) status or MMR protein mutation and genetic testing to identify precancerous lesions and early cancers. In terms of prevention, oral contraceptives and preventive surgery removing the uterus and ovaries are used. Women with Lynch syndrome have a 40%~60% lifetime risk of endometrial cancer, and a 4%~24% lifetime risk of ovarian cancer. Therefore, it is of great significance for women with Lynch syndrome to have early screening and prevention of endometrial cancer and ovarian cancer.
