Risk-stratified faecal immunochemical testing (FIT) for urgent colonoscopy in Lynch syndrome during the COVID-19 pandemic.

BACKGROUND: Lynch syndrome is a hereditary cancer disease resulting in an increased risk of colorectal cancer. Herein, findings are reported from an emergency clinical service implemented during the COVID-19 pandemic utilizing faecal immunochemical testing ('FIT') in Lynch syndrome patients to prioritize colonoscopy while endoscopy services were limited. METHODS: An emergency service protocol was designed to improve colonoscopic surveillance access throughout the COVID-19 pandemic in England for people with Lynch syndrome when services were extremely restricted (1 March 2020 to 31 March 2021) and promoted by the English National Health Service. Requests for faecal immunochemical testing from participating centres were sent to the National Health Service Bowel Cancer Screening South of England Hub and a faecal immunochemical testing kit, faecal immunochemical testing instructions, paper-based survey, and pre-paid return envelope were sent to patients. Reports with faecal haemoglobin results were returned electronically for clinical action. Risk stratification for colonoscopy was as follows: faecal haemoglobin less than 10 µg of haemoglobin/g of faeces (µg/g)-scheduled within 6-12 weeks; and faecal haemoglobin greater than or equal to 10 µg/g-triaged via an urgent suspected cancer clinical pathway. Primary outcomes of interest included the identification of highest-risk Lynch syndrome patients and determining the impact of faecal immunochemical testing in risk-stratified colonoscopic surveillance. RESULTS: Fifteen centres participated from June 2020 to March 2021. Uptake was 68.8 per cent amongst 558 patients invited. For 339 eligible participants analysed, 279 (82.3 per cent) had faecal haemoglobin less than 10 µg/g and 60 (17.7 per cent) had faecal haemoglobin greater than or equal to 10 µg/g. In the latter group, the diagnostic accuracy of faecal immunochemical testing was 65.9 per cent and escalation to colonoscopy was facilitated (median 49 versus 122 days, χ2 = 0.0003, P < 0.001). CONCLUSION: Faecal immunochemical testing demonstrated clinical value for Lynch syndrome patients requiring colorectal cancer surveillance during the pandemic in this descriptive report of an emergency COVID-19 response service. Further longitudinal investigation on faecal immunochemical testing efficacy in Lynch syndrome is warranted and will be examined under the 'FIT for Lynch' study (ISRCTN15740250).

Educational and Psychosocial Support Needs in Lynch Syndrome: Implementation and Assessment of an Educational Workshop and Support Group.

Few reports of educational and counseling support resources exist for Lynch syndrome (LS), a disorder requiring multi-organ cancer screening and specialized medical care throughout adult life. Here we describe the development and efficacy of two resources designed to address this need, the Memorial Sloan Kettering Cancer Center Clinical Genetics Service annual Lynch Syndrome Educational Workshop (LSEW), and a quarterly Lynch Syndrome Patient Advocacy Network (LSPAN) support group. The LSEW and LSPAN were implemented beginning in 2012. Participant survey data evaluating satisfaction, clarity, and unmet needs for each event were retrospectively analyzed and summarized using descriptive statistics. Annual LSEW attendance ranged from 53 to 75 total participants. LSEW year 1 participants indicated a need for a support group, and preferred in-person meetings at a frequency of every 3-6 months. For LSEW year 2-5 participants, >96 % reported satisfaction with the LSEW, and >82 % expressed interest in secure online support. Common themes for improvement included increased time for question and answer sessions and additional introductory genetics education. Responding LSPAN participants (n = 57 total survey responses in 11 meetings) found the meetings helpful (100 %), information clear (91 %), and presence of a genetic counselor useful (67 %). Desired discussion topics included coping with stress and anxiety, development of a support network, family communication about LS, genetic testing decisions, and bereavement. Following genetic counseling, a need exists for ongoing educational and emotional support in LS. Implementation of resources such as the LSEW and LSPAN is feasible and perceived as helpful by participants.
