Overview

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.

Eligibility

Inclusion Criteria:

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

      • 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
