About this study
Official title: Prospective Evaluation of Lymph Node Metastasis at the Time of Surgical Staging for High Risk Endometrial Cancer
This clinical trial studies positron emission tomography (PET)/computed tomography (CT) and lymph node mapping in finding lymph node metastasis in patients with endometrial cancer that is at high risk of spreading. A PET/CT scan is a procedure that combines the pictures from a PET scan and a CT scan, which are taken at the same time from the same machine. The combined scans give more detailed pictures of areas inside the body than either scan gives by itself. Lymph node mapping uses a radioactive dye, called indocyanine green solution, to identify lymph nodes that may contain cancer cells. PET/CT and sentinel lymph node mapping may be better ways than surgery to identify cancer in the lymph nodes.
Read the detailed description
PRIMARY OBJECTIVES:
- To estimate the false negative rate of PET/CT and/or sentinel lymph node mapping in the detection of positive lymph nodes in women with high risk endometrial cancers.
SECONDARY OBJECTIVES:
- To estimate the sensitivity, specificity, positive predictive value, and negative predictive value of PET/CT and/or sentinel lymph node mapping in the detection of positive lymph nodes in women with high risk endometrial cancer.
II. To determine if a molecular panel of estrogen-induced genes that we have previously identified from retrospective studies correlate with extra-uterine spread including lymph node metastasis at the time of surgical staging for endometrial cancer.
III. To prospectively identify patterns of lymphatic spread of endometrial cancer.
IV. To correlate cancer antigen 125 (CA-125) and WAP four-disulfide core domain 2 (HE4) levels with disease metastasis at the time of surgical staging and to explore the use of other serum biomarkers to predict recurrence.
- To prospectively collect morbidity and mortality data related to performing lymph node dissection including intra-operative and postoperative complications.
VI. To determine whether metabolic parameters of the primary endometrial tumor on PET including tumor intensity (maximum standard uptake value [SUV] and peak SUV), metabolic tumor volume (obtained at a threshold of 40% of maximum and at a threshold of SUV=3), and total lesion glycolysis (expressed average SUV over the metabolic tumor volume) are predictive of locoregional or metastatic spread, and whether these parameters correlate with CA-125 and HE4 levels.

The record lists 7 sites in United States. 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?
Yes. Results are posted in the registry (first posted 28 Nov 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
False Negative Rate of PET/CT Verses Sentinel Lymph Node Mapping in the Detection of Positive Lymph Nodes in Women With High Risk Endometrial Cancers. (time frame: 36 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 8 Oct 2026.
