Evaluation of DNA Methylation Markers for Endometrial Cancer Risk-stratification Using Patient-collected Urine and Vaginal Samples and Clinician-collected Cervical Samples From Women With Postmenopausal Bleeding

The goal of this observational study is to investigate the clinical utility of DNA-methylation testing in urine and vaginal samples collected by patients and cervical samples collected by clinicians, to determine the risk of endometrial cancer in symptomatic women with postmenopausal bleeding. The study aims to answer the following research questions: * What is the diagnostic accuracy of DNA methylation testing in urine, vaginal and cervical samples compared to traditional TVUS for endometrial cancer detection? * What is the 2-year risk of EC among women testing negative on TVUS and/or DNA methylation tests or those testing positive on methylation only? Researchers will compare DNA methylation testing in patient-collected urine and vaginal samples as well as in clinician-collected cervical samples, with the traditional diagnostic pathway for women with PMB, which includes TVUS evaluation, and when indicated by abnormal TVUS findings, endometrial biopsy according to clinical guidelines. Participants will * take a urine and vaginal sample * have a cervical sample collected by a clinician * undergo TVUS evaluation according to clinical guidelines * If TVUS shows thickened endometrium (≥ 5 mm) and/or irregularity, an endometrial biopsy will be collected according to clinical guidelines * fill out a questionnaire regarding acceptability and preferences of sampling methods and complete a lifestyle questionnaire.

The Clinical Utility of DNA Methylation Testing in Patient-collected Urine and Vaginal Samples to Detect Endometrial Cancer: a Case-control Study

The goal of this observational case-control study is to investigate the use of DNA-methylation testing in patient-collected urine and vaginal samples to detect endometrial cancer. The study aims to answer the following questions: * Can DNA methylation testing in vaginal and full-void urine samples distinguish endometrial cancer cases from healthy controls? Researchers will compare patient-collected urine and vaginal samples from patients with diagnosed endometrial cancer (cases) to gynaecologically and oncologically healthy controls (controls). Participants will * take a urine and vaginal sample at the hospital. * answer a questionnaire regarding acceptability and preferences of self-sampling methods. * answer a lifestyle questionnaire.
