Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with suspected early stage endometrial cancer and no signs of extra-uterine disease.

Probably not a fit

Patients who are planned for laparotomic hysterectomy or those on progesterone therapy for endometrial cancer may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates whether the use of a uterine manipulator during minimally invasive surgery for early stage endometrial cancer affects the presence of cancer cells in the surgical fluid. Patients will be randomly assigned to two groups: one receiving surgery with a uterine manipulator and the other without. The aim is to determine if the manipulator increases the risk of cancer cell spread during the procedure. This research addresses a significant gap in understanding the potential risks associated with this common surgical practice.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical practices that minimize the risk of cancer spread during surgery.

How similar studies have gone: While there is limited research directly addressing this issue, the study aims to fill a gap in existing knowledge regarding uterine manipulators in surgical procedures.
