Molecular and cellular analysis of uterine lavage from gynecologic surgery

Exploring the Molecular and Cellular Composition of Uterine Lavage Specimens Collected at the Time of Gynecologic Surgery.

Not applicable Interventional Stanford University · NCT07044505

This will try a new uterine lavage catheter to collect samples from up to 50 adults having gynecologic surgery to see what cells are present.

What this trial studies

This is a prospective, consecutively-enrolled cohort of up to 50 adults undergoing gynecologic surgery at Stanford who will each have a uterine lavage sample collected with a novel catheter. The primary aim is to test the clinical and technical feasibility of collecting uterine lavage and to describe the molecular and cellular composition of the samples. Collected samples will undergo molecular and cellular profiling to characterize cell types and any disease-related signals. The procedure is performed intraoperatively and does not change the participant's planned surgical care.

Who should consider this trial

Good fit: Adults (18+) scheduled for gynecologic surgery at Stanford with an intact uterus and cervix, at least one intact fallopian tube and ovary on the same side, and the ability to provide informed consent.

Not a fit: People who are not having surgery at Stanford, who lack an intact uterus or cervix, have known endometrial or cervical cancer, have an IUD, are pregnant, or cannot consent are excluded and unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, this approach could enable better, less invasive sampling of uterine and adnexal tissues to inform future diagnostics or research into gynecologic disease.

How similar studies have performed: Related uterine lavage and cytology research has produced promising sampling results, but intraoperative molecular and cellular profiling using this specific catheter is relatively novel.
