Plain English Summary

Background and study aims
Lynch Syndrome (LS) is an inherited disorder that results in an increased lifetime risk of several cancers, including colorectal cancer (CRC). It is estimated that nearly 175,000 people in the U.K. have Lynch Syndrome, though fewer than 5% (~8,750) are known.
Given the increased risk of CRC for individuals with LS, colonoscopy (a test to check inside the bowels) is recommended every two years for patients with LS within England, which may begin between the ages of 25 – 35 and last until 75 years of age. Though colonoscopy is presently considered the gold standard for the detection of colonic lesions, the requirement of having up to 25 colonoscopies throughout a LS patient’s lifetime is invasive and resource intensive.
For this research study, we are proposing the use of a non-invasive, self-sampling diagnostic device known as the faecal immunochemical testing (FIT) kit for patients with LS. FIT is a CLIA-waived diagnostic device designed to detect trace amounts of faecal haemoglobin (f-Hb) and used to guide clinical referral for lower gastrointestinal investigation, often to colonoscopy. Despite the routine use of FIT in population-based CRC screening programmes within the U.K. and abroad, the role of FIT for patients with LS is unknown.

Who can participate?
Individuals (men and women) aged 25 – 75 years, who have a diagnosis of Lynch Syndrome.

What does the study involve?
In this study, we will offer eligible LS patients an OC-Sensor™ FIT kit via mail at baseline, and annually for 3 years thereafter. Patients will also receive additional study materials at baseline, as well as a pre-notification letter just prior to baseline. After the trial has ended, we will continue to passively observe a subset of trial participants (those with preceding negative FIT results), for the observation of interval CRC’s. The mechanism for collecting long-term follow up data at 3 years is dependent on future funding, however, and will therefore be decided at a later date.

What are the possible benefits and risks of participating?
By participating in this study there is a chance that your FIT results may provide your clinician with additional information which may assist them with your clinical care. You will also be contributing to research that will help improve surveillance for people with Lynch Syndrome in the future. There are no immediate risks in taking part in this research study, and it is unlikely that you will come to any harm while collecting a stool sample as part of the FIT kit sampling. FIT testing is used routinely as part of the National Bowel Cancer Screening Programme and has been deemed safe and effective in this setting. You may, however, be referred for an additional colonoscopy(s). Although this procedure is not considered as part of this research study, there are some risks associated with colonoscopies. Please enquire about any of these risks directly with your consultant.

Scientific titleExploring the utility and acceptability of Faecal Immunochemical Testing (FIT) as a novel intervention for the improvement of Colorectal Cancer (CRC) surveillance in individuals with Lynch Syndrome
Study acronymFIT for Lynch Syndrome
Study hypothesisBased upon preliminary data which came from a preceding emergency clinical service evaluation examining the utility of FIT in patients with Lynch Syndrome throughout the COVID-19 pandemic, we believe that a structured programme and longitudinal research with annual FIT alongside biannual colonoscopy in this patient cohort will enable a robust dataset to examine the efficacy of FIT as an additive, non-invasive diagnostic modality for the purposes of surveillance in patients with Lynch Syndrome.
Ethics approval(s)Approved 25/03/2021, Yorkshire & The Humber – Bradford Leeds Research Ethics Committee (NHSBT Newcastle Blood Donor Centre, Holland Drive, Newcastle upon Tyne, NE2 4NQ, UK; +44 (0)2071048083; bradfordleeds.rec@hra.nhs.uk), ref: 21/YH/0066
ConditionLynch Syndrome (hereditary non-polyposis colorectal cancer)
InterventionA baseline mailing will be sent to eligible participants within 30 days of their next standard of care colonoscopy to include the following study materials and items:
-A study invitation letter
-A FIT kit (OC-Sensor brand) enclosed within a biospecimen sample bag
-Consent form
-FIT instruction sheet (to have pictorial and written instructions for collection)
-A baseline questionnaire
-A patient information sheet
-Return envelope w/ prepaid postage

Eligible patients may read about the study in greater detail within the study invitation letter and the patient information leaflet. Interested patients will then be asked to provide a small faecal sample within the provided FIT kit and per the enclosed FIT instruction sheet. Additionally, they will be asked to complete the consent form and baseline questionnaire (which will assess attitudes of acceptability and preferences for this novel intervention, as well as current medications), all of which will be returned to the NHS Bowel Cancer Screening Programme Southern Hub (referred to as the "Southern Hub" herein), in Guildford, Surrey via the provided return envelope with prepaid postage.

FIT (self-sampling) kits will be posted to enrolled patients annually for 3 years after baseline (Years 1-3) and will include the FIT kit for sample collection, the FIT instruction sheet, a post-baseline letter, and a return envelope with prepaid postage for return to the Southern Hub.

At intervening years between patient's routine (biennial) colonoscopy (years 1 & 3), FIT will be used to inform colonoscopy triage for patients whose result exceeds an upper threshold of 6 micrograms of haemoglobin per gram of faeces. For patients whose FIT result exceeds the pre-defined upper threshold at those intervening years (whom we expect to be a small minority), results will be disclosed via their physician (Co-I) and they will be advised to proceed with a colonoscopy which shall be triaged via the two-week wait (2WW) pathway.

A subset of FIT-negative patients will be passively followed-up 3 years after the trial ends for the observation of interval CRC's.

To address the primary aim of the study, we will compare results from FIT and the respective pathology and/or histology reports from endoscopy following each colonoscopy from baseline through the subsequent 3 years (4 years total).
Intervention typeOther
Primary outcome measureConfirmation of no visible CRC at time of colonoscopy and subsequent negative pathology report for patients who had preceding negative FIT results. The absence of colorectal cancer is measured by colonoscopy for participants with preceding negative FIT results (<6 micrograms of haemoglobin / g of faeces) at Baseline and Year 2
Secondary outcome measures1. The overall acceptability of this novel intervention (FIT) by this patient population (Lynch Syndrome) will be measured through the use of a participant questionnaire which will be distributed at baseline
2. Confirmation of colorectal neoplasia (CN) at time of colonoscopy, and subsequent confirmation via pathology report for patients who had preceding positive FIT results over the 3-year interventional follow-up period
3. Gut microbiota measured using 16S next-generation sequencing on residual DNA from archived FIT samples at a single time point
4. Colorectal cancer (CRC) diagnoses from patient records in a subset of patients who had negative FIT results at Baseline and Years 1-3 to record for potential interval cancers through Baseline, Years 1-3, and passive follow-up years 4-6
5. Advanced colorectal neoplasia (ACN) at time of colonoscopy, and subsequent confirmation of malignancy on pathology report using patient records over the 5 year follow up period
