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.

Retrospective cohort study

OTHER

a retrospective cohort will be set up to provide an exhaustive overview of the approaches used for endometrial cancer, according to patient characteristics (age and BMI). It will include all patients not included in the randomized controlled trial and in the prospective cohort because the surgeon did not propose it to them, because they did not wish to be followed up for the study for 6 months, or because the surgeon considered that minimally invasive surgery was not indicated; up to a limit of 1000 inclusions.

Other: Retrospective cohort studyOther: information and consentOther: Collection of data

Interventions

The experimental procedure corresponds to robot-assisted laparoscopy.

Randomized study: Robot-assisted laparoscopy

The "control" procedure corresponds to conventional laparoscopy.

Randomized study: conventional laparoscopy

A prospective cohort of patients will be set up to support the randomized controlled trial. Patients will be offered participation in this cohort if the center is unable to participate in the randomized trial (i.e., does not have a robot, or does not have a laparoscopic column with fluorescence), if the patient refuses randomization in the randomized controlled trial, if the surgeon refuses to randomize the patient, or if the surgeon does not meet the learning curve criteria required for robotic surgery. These patients will be followed in exactly the same way as patients included in the randomized controlled trial, once their consent has been obtained.

Prospective cohort study

Retrospective data collection from the medical records of all patients who underwent hysterectomy for low- or intermediate-risk endometrial cancer during the inclusion period at a participating center and who were not included in the randomized controlled trial or prospective cohort; up to a limit of 1000 inclusions. For this retrospective cohort, only data concerning initial age, BMI, histological type of cancer and surgical approach used will be collected.

Model Details: As part of this project, we 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 hysterectomy * Group 2: conventional laparoscopic hysterectomy A prospective cohort based on the randomized controlled trial A retrospective cohort
