Could a simple swab catch uterine cancer before it spreads?
NCT ID NCT06268626
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to find a gentler way to detect uterine cancer early in people with abnormal bleeding. Instead of relying only on a biopsy, researchers will use a health questionnaire and a self-collected vaginal swab to look for cancer-related genetic changes and microbiome patterns. About 1,000 participants will be followed for 6-8 months to see how well these non-invasive methods work compared to standard biopsy results.

This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The study investigators will have 10-15 study gynecologists across British Columbia, Canada, who will be recruiting study participants from patients who are referred to them for an endometrial biopsy due to abnormal uterine bleeding. The investigators aim to recruit \~1000 participants in Study Part A in order to achieve their target sample size of n=50 EIN/EC and n=150 EH. Sequenced participants will be invited to participate in Study Part B/ Longitudinal monitoring and provide additional samples.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: Study Part A: * 40 years and older * Experiencing unexplained abnormal uterine bleeding (i.e., not from IUD, etc.) * Have an intact uterus * Referred for an endometrial biopsy Study Part B/Longitudinal monitoring: * Those selected for sequencing (from Part A) and who retained their uterus. Exclusion Criteria: Study Part A: * Endometrial sampling, pelvic radiation, or vaginal infection (vaginosis, yeast) in the past 3 months * Started hormone therapy (HRT, birth control, IUD) in the past year (with the exception of tamoxifen) * Intercourse, vaginal product use, or douching in the past 48 hours Study Part B/Longitudinal monitoring: * Same as Study Part A * EC or EIN, or anyone who is recommended a hysterectomy
