What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 3 trials are large pivotal studies comparing the treatment to current standard of care or placebo. Your participation directly contributes to the evidence needed for regulatory approval.

This trial targets 428 participants in total. It began in 2022-12-07 with a primary completion date of 2026-10-31.

Brief Summary

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.

Eligibility Criteria

Inclusion Criteria: * Histologically proven diagnosis of endometrial cancer based on endometrial sampling with a plan to undergo laparoscopic or robotic hysterectomy and lymphatic assessment as part of primary management. Biopsy must be performed within 90 days prior to registration * Clinical stage I endometrial cancer based on the following diagnostic workup: * History/physical examination within 30 days prior to registration is reassuring for the absence of metastatic disease * Age \>= 18 years * Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1 or 2 * Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial * The patient or a legally authorized representative must provide study-specific informed consent prior to study entry and, for patients treated in the United States (U.S.), authorization permitting release of personal health information * Patients must speak English, Spanish, or Korean Exclusion Criteria: * Patients whom the surgeon believes is not a candidate for pelvic lymphadenectomy due to medical comorbidities or other technical challenges (i.e. morbid obesity or prior surgery) * History of chemotherapy or immunotherapy for the treatment of endometrial cancer. Progestin-containing therapies such as megestrol, medroxyprogesterone, or levonorgestrel-containing intrauterine device (IUD) are acceptable * History of radiation to the pelvis, groin or lower extremities, or surgery to the pelvic lymph nodes or inguinal lymph nodes * Patients who are going to undergo another elective surgery during the same operative event as their hysterectomy (i.e., sacrocolpopexy, cholecystectomy) * Patients with severe, active co-morbidity defined as follows: * History of patient or provider identified lower extremity lymphedema * History of patient or provider identified chronic lower extremity swelling * History of lower extremity or pelvic deep venous thromboembolism within 90 days of registration * History of lower extremity cellulitis within 90 days of registration
