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.

Clinical Studies of Endometrial Cytology and Cervical Methylation Assays in Endometrial Cancer Screening and Fertility-Preservation Evaluation

The current study aims to assess high-risk patients using both liquid-based cytology and cervical methylation testing. The results will be compared with the traditional hysteroscopic pathological findings to determine the sensitivity and specificity of these methods for early detection of endometrial cancer, thereby evaluating their potential application in early screening. Primary Objectives： 1. To evaluate the sensitivity, specificity, and accuracy of endometrial cytology for screening endometrial cancer. 2. To assess the sensitivity, specificity, and accuracy of methylation testing for screening endometrial cancer. 3. To perform further molecular testing on tissue samples obtained from endometrial cytology and cervical methylation tests, aiming to explore early screening-sensitive indicators. Secondary Objectives： 1. To determine the value of endometrial cytology in evaluating the efficacy of fertility-sparing treatments for endometrial cancer. 2. To assess the value of methylation testing in evaluating the efficacy of fertility-sparing treatments for endometrial cancer.

A Study of Tilvestamab (BGB149) in Relapsed, Platinum-resistant, High-grade Serous Ovarian Cancer (HGSOC) Participants

The primary purpose is to assess the safety and tolerability of tilvestamab following IV administration of multiple doses to participants with HGSOC who have been treated with at least 1 complete course of platinum-based chemotherapy and whose disease has relapsed with platinum resistance (\[PRR\]-HGSOC) and to determine the plasma pharmacokinetics (PK) exposure by comprehensive profiling (at single dose and steady-state) of multiple ascending doses of tilvestamab.
