Registration Number

Lead Sponsor
Rennes University Hospital
Brief Summary

The standard treatment for endometrial cancer is surgery, as long as the stage of the disease and the patient's condition allow. It consists of hysterectomy (TSH) with bilateral adnexectomy. The recommended surgical approach is the minimally invasive or laparoscopic route, whose oncological safety has been demonstrated by the LAP2 study.

Since 2010 and the arrival of robotic surgery in gynaecology, the robot-assisted laparoscopic approach has gradually been used for endometrial cancer Hysterectomy.

Several studies have suggested that the cost and effectiveness of laparoscopy may vary according to the age and body mass index of the patient.

The investigators therefore hypothesise that robot-assisted laparoscopy may be more efficient than conventional laparoscopy for endometrial cancer hysterectomy in the context of an advanced learning curve in France.

The investigators therefore hypothesise that robot-assisted laparoscopy could be more efficient than conventional laparoscopy for endometrial cancer hysterectomy in the context of an advanced learning curve in France. The investigators will also test the efficiency of the surgical technique as a function of age and Body mass Index.

Detailed Description

As part of this project, the investigators are proposing an original approach by combining a randomized controlled trial with a prospective observational cohort and a retrospective cohort.

This research will therefore consist of 3 complementary studies :

A multicenter, parallel-group, open-label, randomized controlled superiority trial (ratio 1:1) comparing two groups:

* Group 1: laparoscopic robot-assisted THR

* Group 2: conventional laparoscopic STH A prospective cohort based on the randomized controlled trial A retrospective cohort Qualitative analysis of perceptions of the benefits and limitations of the surgical robot, and of the obstacles and levers to its deployment: focus groups with a sample of gynecology surgical teams from volunteer centers.
