EC_ItaLynch: Mainstreaming the Diagnosis of Lynch Syndrome (EC_ItaLynch)

EC_ItaLynch: Incorporating Lynch Syndrome Genetic Testing in Standard Medical Care of Patients With Endometrial Cancer (Mainstreaming)

Lynch syndrome (LS) is the most common cause of hereditary endometrial cancer (EC) and is associated with an increased risk of colorectal (CRC), ovarian, gastric, small bowel and urinary tract cancer. LS is determined by germline pathogenic variants in the DNA mismatch repair (MMR) genes (MLH1, MSH2, MSH6, PMS2) or in EPCAM.

Approximately 20-30% of ECs exhibit somatic MMR deficiency (dMMR), and among these patients approximately 10-30% are affected by LS. This estimate suggests that the prevalence of LS among all EC patients is roughly 3-5%. Prior to the introduction of Universal Screening, the diagnostic management of LS was mainly based on Selective Screening, which included clinical criteria based on the evaluation of family and personal history and the clinicopathological features of the tumor (Amsterdam criteria 1990, Bethesda criteria 1997). However, these have been limited in their application to clinical practice due to their complexity and the frequent lack of complete family history data. Therefore, Universal Screening for LS diagnosis by the identification of dMMR in the tumor tissue of all newly diagnosed CRC and EC cases has recently been proposed.

Universal Screening for LS in tumor tissue includes an immunohistochemistry based (IHC) test to assess loss of MMR protein expression or a polymerase chain reaction (PCR) test for microsatellite instability.

In the traditional diagnostic pathway for LS, genetic counseling and testing are always recommended for EC patients who are found to have loss of expression of any of the proteins encoded by the MSH2, MSH6, or PMS2. In case of MLH1 loss, genetic counseling and genetic testing are recommended for patients without hypermethylation of the MLH1 promoter.

Recent findings suggest that incorporating genetic testing in an oncologist-driven diagnostic algorithm (mainstreaming of genetic testing) could enable increased diagnostic rates, offering the benefits of precision medicine and a streamlined pathway of care to patients and their families.

The study consists of two parts:

  1. In the first part the aim of the current study is to compare the knowledge, experience and understanding of genetic testing among patients pursuing genetic testing using mainstreaming or standard genetic counseling through modified Modified Royal Marsden Patient Satisfaction Questionnaire.
  2. If the first aim will be achieved, a second part will be conducted, to evaluate the feasibility of the mainstreaming diagnostic pathway for LS.

Study Overview

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.

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.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2024

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
