Endometrial Carcinoma
Conditions
Brief summary
This phase I trial investigates the development of a new early detection test to reduce racial disparities in endometrial cancer death rates. DNA samples collected from a tampon may be able to be used to detect endometrial cancer. Studying information from focus groups and vaginal samples of African American and white women may help researchers develop a less invasive and painful test to detect endometrial cancer. The purpose of this trial is to perform a demonstration project of tampon self-collection, assess percentage of samples returned; total and endometrial derived DNA quantity and quality, preliminarily test previously validated DNA methylation markers that may discriminate endometrial cancer from normal endometrium in tampon specimens.
Detailed description
PRIMARY OBJECTIVES: I. To conduct focus groups to elicit perceptions and knowledge among African American women (AAW) and white women (WW) concerning abnormal uterine bleeding (AUB)/post-menopausal bleeding (PMB), endometrial cancer (EC) risk factors, barriers to seeking medical evaluation, sources of medical information and acceptance and feasibility of tampon self-collection for laboratory testing. II. To perform a demonstration project of tampon self-collection from 25 AAW and 25 WW with AUB/PMB in Jacksonville. OUTLINE: AIM 1: Participants attend a focus group over 2 hours about endometrial cancer including knowledge of abnormal uterine bleeding, post-menopausal bleeding, risk factors, sources of medical information, barriers to seeking gynecologic care, and acceptance of tampon self-collection for endometrial cancer detection. AIM 2: Participants receive a tampon kit for collection of vaginal samples. After completion of study enrollment, participants may be followed up annually for 10 years.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Differences in views on endometrial cancer (EC) risk between African American and white women and whether the former would be willing to participate in tampon testing (Aim 1) | Up to 12 months | Survey data will be reported as frequencies and proportions to describe the sample. Survey data will also be used to aid in interpretation of the qualitative data as appropriate. |
| Total deoxyribonucleic acid (DNA) (Aim 2) | Up to 12 months | — |
| Endometrial DNA (Aim 2) | Up to 12 months | — |
| Detection of EC-specific methylation markers (Aim 2) | Up to 12 months | Will test samples for top EC-specific DNA methylation markers using methylation-specific polymerase chain reaction and provide descriptive statistics for all measurements (mean, median, standard deviation). Will assess the percentage of samples that yield \> 500 ng amplifiable DNA, which suffices for methylation assays. |
