Controversial tool under scrutiny: could a simple device raise cancer recurrence risk?
NCT ID NCT05687084
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This trial is testing whether using a uterine manipulator during minimally invasive hysterectomy for endometrial cancer affects the chance of cancer coming back. About 1,030 women with early-stage endometrial cancer will be randomly assigned to have surgery with or without the device. The goal is to provide clear evidence on whether the manipulator is safe or should be avoided.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Uterine manipulator device
- What this could lead to
- If it works, this could show that using a uterine manipulator is safe, or that avoiding it reduces cancer recurrence risk.
- What could go wrong
- This is a large but early-stage trial comparing a device already in use; results may show no difference or be inconclusive.
