Endometrial Cancer Testing with Vaginal and Endometrial Cell Samples
About this study
- Endometrial cancer is one of the most common gynecologic cancers. If it is caught at an early stage, it can be treated more easily. Women who have this type of cancer often have a history of irregular menstrual bleeding. They may also have abnormal findings during gynecologic exams. Pap smears and cervical cell collection may be able to collect cell samples for cancer testing. However, samples from the vagina or endometrium may produce more accurate results. Researchers want to collect vaginal and endometrial cell samples to improve their tests for and understanding of endometrial cancer.
- To collect vaginal and endometrial cell samples to study endometrial cancer.
- Women at least 18 years of age who have had symptoms of abnormal uterine or post-menopausal bleeding, or abnormal ultrasound findings.
- Participants will be screened with a physical exam and medical history.
- Participants will have a pelvic exam. Before the exam, they will insert a small tampon in the vagina. The tampon will stay in place for about 10 to 30 minutes. The tampon will then be removed and collected for the study.
- During the pelvic exam, tissue will be collected from the uterine lining with a special brush. An additional sample (biopsy) will be collected from the lining.
- A blood sample will also be collected as part of the study.
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.See eligibility criteria
Women should meet at least one of the following criteria:
- Abnormal uterine bleeding
- Postmenopausal bleeding
- Thickened endometrial stripe
- Hereditary predisposition to endometrial cancer (e.g. HNPCC)
- Women referred for endometrial biopsy to evaluate suspicion or high risk of endometrial cancer
- Prior hysterectomy
- Pregnant women (There will be a verbal screen by the clinic nurse and the physician about a potential pregnancy and a pregnancy test may be conducted if there is any doubt)
- Prior pelvic radiation
- Cervical stenosis that renders Tao brush sampling impossible
