Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study seeks to better understand the recurrence of high-risk endometrial cancer. It will collect information about cancer genetics to find out various hereditary or cancer specific genetic variants that may have a role in diagnosis or management and prognosis of cancer. It also seeks to develop a genetic results and medical record databank for future studies.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVE:

I. To generate preliminary data for a risk stratification model for recurrence including traditional histopathologic risk factors, molecular characterization in endometrial cancer patients with features of aggressive disease.

OUTLINE: This is an observational study.

Patients undergo blood and tissue sample collection and have their medical records reviewed throughout the study.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Age ≥ 18 years
* Planned complete surgical staging at Mayo Clinic. Complete surgical staging includes at least total hysterectomy, bilateral salpingo-oophorectomy and lymph node assessment. Sentinel node mapping meets the criteria for lymph node assessment. Peritoneal cytology is recommended. Additional staging procedures such as pelvic and para-aortic nodal evaluation, omental biopsy or omentectomy, may also be utilized for staging in patients based on the clinical situation and at the surgeon's discretion
* At least one preoperative or postoperative feature of aggressive disease \[International Federation of Gynecology and Obstetrics (FIGO) staging used throughout this protocol\]

* Preoperatively:

* Biopsy with grade 3 endometrioid endometrial cancer (EC) or non-endometrioid EC
* Patients with FIGO grade 1-2 EC with evidence of extrauterine disease on imaging (CT, MRI, or PET)
* Postoperatively:

* Endometrial cancer (FIGO) with one or more established risk factors:

* Non-endometrioid histology

* Grade 3
* Lymphovascular space invasion (LVSI), ≥ 50% of myometrial invasion, presence of isolated tumor cells (ITC) in a sentinel lymph node OR
* Stage II to IV (FIGO) EC
* Provide written informed consent
* Willingness to provide mandatory blood specimens for correlative research
* Willingness to provide mandatory tissue specimens for correlative research
* Willingness to return to registering site for clinical follow-up

Exclusion Criteria

* Patient receiving or who has received neoadjuvant chemotherapy
* Pre-operative pregnancy
