## TL;DR

A new national program in England improves colonoscopy access and quality for Lynch syndrome patients by integrating them into the bowel cancer screening system.

## Contribution

A novel national screening program for Lynch syndrome patients that ensures equitable, high-quality colonoscopy access without requiring referral.

## Key findings

- A backlog of over 1000 overdue colonoscopies for Lynch syndrome patients was cleared by January 2024.
- Over 10,913 eligible Lynch syndrome individuals were identified by November 2024.
- More than 2000 staff across 64 screening centers received standardized training in 2023.

## Abstract

Quality assurance, timeliness and equity of access to colonoscopy for people with Lynch syndrome (LS) in England has historically been highly variable. The LS-Bowel Cancer Screening Programme (LS-BCSP) launched in July 2023, delivers high quality colonoscopy to the average-risk population, from colonoscopists who have undergone high-level accreditation, utilising the existing average-risk BCSP infrastructure. Eligible individuals have a genetic diagnosis of LS. Comprehensive retrospective diagnoses of LS in England (since the 1990s) were ascertained from 17 regional genetics services. The National Disease Registration Service (NDRS) developed a registry of eligible individuals, and a portal for prospectively diagnosed cases. An existing national screening IT framework was adapted to incorporate disease-specific clinical pathway information, linked to existing national guidelines. Nationally standardised training for BCSP teams was delivered to > 2000 staff from 64 national screening centres in 2023. By November 2024, 10,913 eligible individuals were identified, with 150–250 new diagnoses added each month. A historical backlog of > 1000 patients overdue colonoscopy surveillance was cleared by January 2024. Diagnostic outcomes of LS patients from the first two years of LS-BCSP will be available to facilitate evaluation of the successes and failures of the LS_BCSP. This evaluation will include diagnostic outcomes, stratified by demographic and socioeconomic status, genotype, measures of colonoscopy quality and regional variation. This novel programme includes complete ascertainment of the national LS population in England, without requirement for referral. Individuals with LS now have access to high-quality, timely colonoscopy through an accredited programme which is quality-assured along the entire pathway.
