Could a simpler surgery be safer for aggressive uterine cancer?
NCT ID NCT06900582
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two surgical approaches for women with early-stage, high-risk endometrial cancer that has a p53 gene mutation. One group will get the standard extensive lymph node removal, while the other gets a less invasive sentinel node biopsy. The goal is to see if the simpler procedure is just as good at preventing cancer from coming back, with fewer side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Sentinel lymph node mapping (a less invasive surgical procedure to check for cancer spread)
- What this could lead to
- If successful, this could show that a less invasive surgery is safe for women with this aggressive type of endometrial cancer, reducing side effects like lymphedema.
- What could go wrong
- This is a relatively early-stage trial (Phase NA) with 374 participants. The less invasive approach might not catch all cancer spread, potentially leading to higher recurrence rates.

Inclusion Criteria: 1 . ≥ 18 years old 2. High-risk endometrial cancer, as defined by the ESGO-ESTRO 20211 histological and molecular classification, with p53 mutation confirmed on endometrial biopsy or curettage in the two months before the surgery 3. Magnetic Resonance Imaging (MRI) confirmed FIGO 2023 stage I and II endometrial cancer, i.e., confined to the uterine corpus, ovary and the cervical stroma. 4\. Participant with a scheduled surgical intervention (total hysterectomy and bilateral salpingo-oophorectomy, with omentectomy in the case of serous, carcinosarcoma and undifferenciated type EC) 5. Eligible for comprehensive lymphadenectomy by laparoscopy 6. Participant with a negative Positron Emission Tomography scan (PET-CT scan) for lymph node involvement in the two months before the intervention 7. ECOG (Eastern Cooperative Oncology Group) performance status of 0-1 8. Participant able to provide written informed consent Exclusion Criteria: 1. Recurrent EC 2. Previous chemo-, radio, or endocrine therapy for EC 3. Any contra-indication to lymphadenectomy and/or chemotherapy 4. Any contraindication to laparoscopy 5. Any criteria, based on the investigator's judgment, that would contraindicate the surgical procedure (e.g., but not limited to, anesthetic risk, bleeding, significant comorbidities) 6. Any known disorder or circumstances making participation in trial and follow-up questionable 7. Patients with other malignancies for whom the disease(s) and/or associated treatment(s) might have an impact on the patient's cancer prognosis 8. Known HIV-infection or AIDS 9. Simultaneous participation in another interventional clinical trial 10. Within the exclusion period following participation in another interventional clinical trial 11. Patients with difficulties in reading or understanding French, or an inability to understand the delivered information 12. Patients in emergency medical situations 13. Patient under guardianship or limited guardianship
