About this study
Official title: Preoperative Risk Stratification in Endometrial Cancer Using Expert Ultrasound and Molecular Classification for Tailoring Lymph Node Staging: Multicentric Prospective Observational Study
The goal of this observational study is to evaluaty the accuracy of current risk stratification of patients with endometrial cancer and to redefine lymph node staging recommendations based on real-world clinical data. The main question it aims to answer is:
Is there any group of patients who doesn't need lymph node staging for proper indication of adjuvant treatment? Participants are note taking any intervention. They are treated according to current standard of care and followed 3-years after primary surgery.
- Conditions

What is being measured
The primary outcome is the main question the study is designed to answer.
The accuracy of preoperative risk stratification
Measured: From enrollment to the first follow-up visit at 4 weeks after surgery.
Determination of specific groups for whom: 1) lymph node staging is crucial for changing risk category and adjuvant treatment decisions, and 2) lymph node staging could be safely omitted
Measured: From enrollment to the first follow-up visit at 4 weeks after surgery.

Where is the study taking place?
The record lists 1 site in Czechia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The accuracy of preoperative risk stratification (time frame: From enrollment to the first follow-up visit at 4 weeks after surgery.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07368205, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 May 2026.
