Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include women aged 45 and older with abnormal uterine bleeding or postmenopausal bleeding, as well as younger women aged 18-44 with similar symptoms and risk factors for endometrial cancer.
✕Probably not a fit
Patients with a prior hysterectomy, current pregnancy, or those with recent cancer diagnoses or treatments may not benefit from this study.

What this trial studies
This project aims to develop a diagnostic test for early detection of endometrial, ovarian, and cervical cancers by utilizing specific methylated DNA markers found in vaginal fluid and plasma. The study will involve collecting samples from women experiencing abnormal uterine bleeding or postmenopausal bleeding, as these symptoms are often associated with gynecologic cancers. The research will focus on distinguishing between benign conditions and cancerous lesions, potentially reducing the need for invasive diagnostic procedures. The study will also explore the specificity of these markers among various benign gynecologic conditions.
Why it matters
Potential benefit: If successful, this test could provide a less invasive and more accurate method for early detection of gynecologic cancers, improving patient outcomes.
How similar studies have gone: While there have been advancements in cervical cancer screening, this approach for detecting other gynecologic cancers using methylated DNA markers is relatively novel and has not been extensively tested.
