About this study
Official title: A Phase III Trial Of The Impact Of Sentinel Lymph Node Mapping On Patient Reported Lower Extremity Limb Dysfunction In Endometrial Cancer
This phase III trial compares the effect of sentinel lymph node mapping to standard lymph node dissection in reducing the risk of swelling in the legs (lymphedema) in patients undergoing a hysterectomy for stage I endometrial cancer. Standard lymph node dissection removes lymph nodes around the uterus during a hysterectomy to look for spread of cancer from the uterus to nearby lymph nodes. Sentinel lymph node mapping uses a special dye and camera to look for cancer that may have spread to nearby lymph nodes. Comparing the results of the procedures may help doctors predict the risk of long-term swelling in the legs.
Read the detailed description
PRIMARY OBJECTIVES:
- To compare the rates of lower extremity limb dysfunction (defined as a >= 4-point increase in Gynecologic Cancer Lymphedema Questionnaire [GCLQ] symptom score from baseline) in patients with apparent uterine confined endometrial cancer randomized to one of two lymphatic assessment strategies at time of hysterectomy:
Ia. Sentinel lymph node mapping and excision followed by side-specific lymphadenectomy on sides without a sentinel lymph node (SLN) identified according to a National Comprehensive Cancer Network (NCCN) guidelines approved algorithm (Arm 1); Ib. Sentinel lymph node mapping and excision according to an NCCN Guidelines approved algorithm followed by bilateral pelvic +/- para-aortic lymphadenectomy (Arm 2).
SECONDARY OBJECTIVE:
- To compare changes in lower extremity limb circumference in patients with apparent uterine confined endometrial cancer randomized to one of two lymphatic assessment strategies at time of hysterectomy.
II. To validate the test characteristics of a SLN mapping algorithm including SLN detection rates, rate of perioperative complications, rate of identifying lymphatic metastases, and detection of micrometastases using pathologic ultra-staging.
EXPLORATORY OBJECTIVES:
- To compare adjuvant therapy decisions in patients with apparent uterine confined endometrial cancer randomized to one of two lymphatic assessment strategies at time of hysterectomy.
II. To explore the impact of patient characteristics (age, body mass index [BMI], race), extent of lymph node dissection, and adjuvant therapy decisions (radiation, chemotherapy) on the development of lower extremity limb dysfunction - as well as their interaction with lymph node assessment strategies.
III. To evaluate the cost-effectiveness of SLN mapping with or without completion of lymphadenectomy for endometrial cancer.
SAFETY OBJECTIVE:
- To compare progression free and overall survival in patients with apparent uterine confined endometrial cancer randomized to one of two lymphatic assessment strategies at time of hysterectomy.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM 1: Patients receive ICG dye via injection and undergo sentinel lymph node mapping and excision during standard minimally invasive hysterectomy. Lymph nodes around the uterus may be removed if the mapping and excision cannot be completed. Successful mapping requires no additional removal of lymph nodes.
ARM 2: Patients receive ICG dye via injection and undergo sentinel lymph node mapping and excision during standard minimally invasive hysterectomy. Additional lymph nodes around the uterus are removed per standard of care.
Patients in both arms also undergo imaging as clinically indicated and optional blood sample collection throughout the study.
After completion of study intervention, patients are followed every 3 months for one year and at 18 and 24 months.

What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of patient-reported lower extremity limb dysfunction
The primary endpoint is the incidence of patient-reported lower extremity limb dysfunction at 18 months post-hysterectomy after undergoing lymphatic assessment according to a National Comprehensive Cancer Network guideline-based sentinel lymph node (SLN) mapping algorithm with or without completion of lymphadenectomy. The primary endpoint will be assessed using the Gynecologic Cancer Lymphedema Questionnaire (GCLQ) questionnaire. Surveys will be performed at enrollment (pre-surgery) and at 3, 6, 9, 12, and 18 months post-surgery. Patient-reported lower extremity limb dysfunction will be defined as an increase in GCLQ symptom score of at least four (4) points from baseline at any time during the 18 months follow-up. The primary null hypothesis will be evaluated with an intent-to-treat chi-squared test, adjusted for stratification factors. Proportional hazards modeling will be used to generate a hazard ratio and 95% confidence limits of Arm 1 versus Arm 2.
Measured: From 18 months post-hysterectomy after undergoing lymphatic assessment to 39 months
Secondary outcomes (4)
The incidence of lymphedema by quantifiable lower extremity limb changes
Patients will undergo circumferential lower extremity limb measures at three locations along each leg. Change will be estimated as measurement at baseline subtracted from measurement at follow-up. This will be assessed in both legs separately.
Measured: From enrollment and at 3, 6, 9, 12, and 18 months after surgery
Rate of successful bilateral SLN identification
Will be assessed in both, and only as the time of surgery.
Measured: At time of surgery
Rate of successful identification of lymph node metastasis
Will be assessed in both, and only as the time of surgery. The rate of lymph node metastasis identification during surgery will be compared between groups, with either t-tests or chi-squared tests where appropriate.
Measured: At time of surgery
Rate of perioperative complications
Will be assessed in both arms separately, and only as the time of surgery. The rate of perioperative complications during surgery will be compared between groups, with either t-tests or chi-squared tests where appropriate.
Measured: At time of surgery

Primary outcome
Incidence of patient-reported lower extremity limb dysfunction
Time frame: From 18 months post-hysterectomy after undergoing lymphatic assessment to 39 months
The primary endpoint is the incidence of patient-reported lower extremity limb dysfunction at 18 months post-hysterectomy after undergoing lymphatic assessment according to a National Comprehensive Cancer Network guideline-based sentinel lymph node (SLN) mapping algorithm with or without completion of lymphadenectomy. The primary endpoint will be assessed using the Gynecologic Cancer Lymphedema Questionnaire (GCLQ) questionnaire. Surveys will be performed at enrollment (pre-surgery) and at 3, 6, 9, 12, and 18 months post-surgery. Patient-reported lower extremity limb dysfunction will be defined as an increase in GCLQ symptom score of at least four (4) points from baseline at any time during the 18 months follow-up. The primary null hypothesis will be evaluated with an intent-to-treat chi-squared test, adjusted for stratification factors. Proportional hazards modeling will be used to generate a hazard ratio and 95% confidence limits of Arm 1 versus Arm 2.
4 secondary outcomes
The incidence of lymphedema by quantifiable lower extremity limb changes
Time frame: From enrollment and at 3, 6, 9, 12, and 18 months after surgery
Rate of successful bilateral SLN identification
Time frame: At time of surgery
Rate of successful identification of lymph node metastasis
Time frame: At time of surgery
Rate of perioperative complications
Time frame: At time of surgery

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Biospecimen Collection, Diagnostic Imaging Testing and Excisional Biopsy in people with Stage I Uterine Corpus Carcinoma or Carcinosarcoma AJCC v8, run by NRG Oncology at 60 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 7 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 60 sites in United States, South Korea. 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.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
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?
Incidence of patient-reported lower extremity limb dysfunction (time frame: From 18 months post-hysterectomy after undergoing lymphatic assessment to 39 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 7 Aug 2026.
