Personalized tool to predict lymph node spread in early endometrial cancer
Official title: ENDORISK Clinical Implementation Study
Run by Radboud University Medical Center · NCT07200466 · Data updated 2026-11-12
This study will test whether using the ENDORISK risk model helps doctors better predict lymph node spread before surgery for people with early-stage endometrial cancer.

Is this trial a fit for you?
✓Likely a good fit
People with early-stage (FIGO I–II) endometrial carcinoma who are eligible for primary surgery, can give informed consent, and understand Dutch or English.
✕Probably not a fit
Patients with rare endometrial sarcomas, advanced-stage disease, those unable to consent, or who cannot communicate in Dutch or English are unlikely to benefit from participation.

What this trial studies
ENDORISK is a Bayesian network model developed to predict preoperative risk of lymph node metastasis in endometrial cancer and has been validated in three external cohorts. This implementation uses a stepped-wedge, non-inferiority design in which two oncology regions start using the model one year apart and clinicians complete the model during preoperative treatment counseling. Outcomes after implementation will be compared to prospectively collected standard-care data to see whether routine use changes risk stratification and surgical decision-making. Eligible patients are those with FIGO stage I–II endometrial carcinoma who are planned for primary surgical treatment.
Why it matters
Potential benefit: If successful, ENDORISK could reduce unnecessary lymph node surgeries and help tailor surgical staging to each patient's actual risk.
How similar studies have gone: The ENDORISK model has been developed and validated with good performance in three external cohorts, but prospective implementation in routine care is novel.
