Brief Summary:

Given that there is a significant prevalence of Lynch syndrome among patients with endometrial cancer (about 5% of patients with endometrial cancer), and given there is a known risk of endometrial cancer among patients with endometrial hyperplasia (40% risk of pre-existing occult cancer with endometrial intraepithelial neoplasia), it is hypothesized that a diagnosis of endometrial hyperplasia may herald on-going risk of harboring a Lynch Syndrome gene mutation.

The purpose of this study is to examine endometrial hyperplasia specimens and compare the frequency of Lynch Syndrome gene mutations between endometrial hyperplasia and endometrial cancer subjects. This will provide a rationale and opportunity for earlier screening, and reduce colon cancer morbidity and mortality secondary to the Lynch syndrome gene.

Condition or disease Intervention/treatment
Lynch Syndrome Endometrial Cancer Endometrial Hyperplasia Mismatch Repair Deficiency Microsatellite Instability Diagnostic Test: Immunohistochemical staining

Detailed Description:
This is an observational cohort study. Tissue specimens obtained that have been labeled with the diagnosis of endometrial hyperplasia will be identified and their chart reviewed for demographic date of age, race, body mass index, and co-morbidities. The specimen will then be tested via immunohistochemistry for the mismatch repair proteins MLH1, PMS2, MSH2, or MSH 6. Their absence is indicative of Lynch Syndrome. Statistical analysis will then be performed to compare the incidence of Lynch syndrome in endometrial hyperplasia with Lynch Syndrome in endometrial cancer.

Study Type : Observational
Estimated Enrollment : 150 participants
Observational Model: Cohort
Time Perspective: Retrospective
Official Title: Frequency of Endometrial Cancer Precursors Associated With Lynch Syndrome
Actual Study Start Date : May 8, 2019
Estimated Primary Completion Date : December 2022
Estimated Study Completion Date : January 2023

Group/Cohort Intervention/treatment
Endometrial hyperplasia
These are patients with a diagnosis of endometrial hyperplasia at WellSpan in the study time frame diagnosed via endometrial biopsy, dilation and curettage, or hysterectomy.
Diagnostic Test: Immunohistochemical staining
Immunohistochemistry will be performed on the endometrial tissue specimens

Primary Outcome Measures :
  1. Lynch Syndrome Screen Positive Rate [ Time Frame: 2014-2022 ]
    This is the rate of subjects who screen positive for Lynch Syndrome based on immunohistochemical staining

Biospecimen Retention:   Samples With DNA
No new biospecimens are retained. The biospecimens referenced are those that were already collected for tissue diagnosis of endometrial hyperplasia: endometrial biopsies, curettage specimens, and hysterectomy specimens. These are kept routinely in the pathology department on microscope slides post-procedure per hospital policy.
