Selective Surgical Staging for the Treatment of Endometrial Cancer Based on Intraoperative Consultation

January 19, 2026 updated by: Frederick R. Ueland, M.D.

Surgical Staging for the Treatment of Endometrial Cancer Based on IOC

Complete pelvic and para-aortic lymphadenectomy performed at the time of primary surgical staging for endometrial cancer increases operative time and surgical morbidity, but appears to be necessary in most high grade and deeply invasive cancers. To date, the Mayo Clinic approach has not been reproduced, and the investigators propose to validate their algorithm at the University of Kentucky utilizing intra-operative consultation (IOC). The preliminary data at the University of Kentucky for IOC and endometrial cancer outcomes suggest that the investigators are well-suited to perform this investigation. A surgical approach that is tailored to the patient's cancer biology is rational, supported by the recent literature, and medically compelling since the co-morbidities of many obese, low-risk EC patients put them at significantly increased perioperative risk for complete lymphadenectomy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
401

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • All patients must be surgical candidates for complete hysterectomy and bilateral salpingo-oophorectomy and pelvic and aortic lymphadenectomy.
  • Patients must have a histologically confirmed diagnosis of endometrial cancer and no clinical evidence of extra-uterine disease on preoperative evaluation.
  • Preoperative evaluation to rule-out extra-uterine disease may include CT scan, MRI, or ultrasound. Preoperative imaging is not mandatory for study enrollment.
  • Patients may have received prior systemic chemotherapy. Such therapy must have been completed at least 5 years prior to study entry and the patient has no evidence of disease subsequent to such therapy. Patients must not have received neoadjuvant chemotherapy for the present disease.
  • Patients must have GOG performance status 0, 1, or 2.
  • Patients must have an estimated survival greater than or equal to 3 months
  • Patients must have signed an approved informed consent and HIPAA authorization.

Exclusion Criteria:

  • Patients with clinical evidence of disease beyond the uterus, including presence of suspicious aortic or inguinal nodes on imaging or clinical exam.
  • Patients who have received previous vaginal, pelvic, or abdominal irradiation.
  • Patients who received chemotherapy directed at the present disease.
  • Patients who have circumstances that will not permit completion of this study or the required follow-up.
  • Patients with renal abnormalities, such as pelvic kidney, horseshoe kidney, or renal transplantation, that would require modification of surgical lymph node assessments.
  • Patients with a history of other invasive malignancies, with the exception of non-melanoma skin cancer within the last five years.
  • Patients with GOG Performance Grade of 3 or 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Recurrence-free survival
Time Frame: 24 months
Recurrence-free survival rates in low-risk and high-risk subgroups of patients with endometrial cancer as classified by the use of pathology intraoperative consultation (IOC).
24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
