#InSiGHT2024

Welcome

Dear Colleagues, Dear Friends,

On behalf of the Board of Directors and the Program Committee it is a great pleasure to invite you to the 2024 Insight Biennial Conference to be held in Barcelona at 19th-22nd June 2024.

This conference, which focusses on the worldwide improvement of care of patients and families with any hereditary condition resulting in gastrointestinal tumors, is a great opportunity and challenge. We aim to make this a great scientific meeting that attracts clinical and research experts in the field, including PhD students and other early career scientists and physicians.

The Program Committee has been working hard to put together a vibrant and comprehensive program for the meeting securing the participation of internationally acknowledged invited experts to address hot topics on key areas in Fundamental, Translational and Clinical Science in sessions with invited speakers and the best peer-reviewed abstracts as oral communications. Workshops will allow lively debating. We will also have the opportunity to listen the voice of patients critical to adequately design our care and our research.

Selected topics include among others: Mutational signatures and somatic evolution in normal tissue; the use of artificial intelligence (AI) in Digital pathology and Endoscopies; and monogenetic defects and Polygenic Risk Scores. Regarding clinical science we will be addressing surgical challenges as well as controversies in surveillance and testing in pediatric and adult settings. Issues on colorectal, gynecological, gastric and biliopancreatic neoplasms will also be discussed. Also chemoprevention, vaccines and lifestyle modification will be tackled. Finally, we have joined forces with the European Society of Gastrointestinal Endoscopy to organize a pre-meeting educational event.

A scientific congress is not just a series of lectures or debates delivered from a podium. There is the social interaction, meeting old friends and making new acquaintances which may turn to become lifelong, discussing a project over a coffee, inviting colleagues to spend time in our unit. Especially for trainees, a congress represents the unique opportunity to meet renowned professionals and establish connections that can lead to new professional opportunities. In this regard, we have done our best to promote the active participation of the young people hoping to help providing effective enduring mentorship to the next generation of physicians, health professionals and scientists.

As Chairpersons of Insight we are very happy and honored to welcome all of you in Barcelona

next June to share and learn the most up to date evidence in our specialty and to enjoy networking with your friends and colleagues.

Kind regards, also on behalf of the InSiGHT Scientific Committee,

ERN GENTURIS is a European Reference Network (ERN) for all patients with one of the rare genetic tumour risk syndromes (genturis).  These patients are at very high hereditary risk of developing multiple tumours, which are often located in multiple organ systems. In case they are diagnosed with cancer they need different treatment and follow-up as compared to non-hereditary cancers. In addition ERN GENTURIS takes care of the relatives of these patients, for which prevention and early detection of tumours is of great importance too.

ERN GENTURIS is working to improve identification of these syndromes, minimize variation in clinical outcomes, design and implement guidelines, develop a GENTURIS registry, support research, and empower patients. The network is educating the public and healthcare professionals and fosters the sharing of best practice across Europe. Access to multidisciplinary care is continuously improved, with new models and standards for sharing and discussing complex cases. The network is enhancing the quality and interpretation of genetic testing and increasing patient participation in clinical research programs. ERN GENTURIS is coordinated by the Radboud university medical center in Nijmegen, The Netherlands. 51 clinical centers in 23 countries are members of ERN GENTURIS

Lynsight (formerly LS CancerDiag) is a Finnish company based in Helsinki and the developer of DiagMMR. This novel test can find inherited functional defects directly in MMR proteins derived from a minute skin biopsy, with high accuracy, and before cancers develop. Patients, families, providers, and payers are stuck in the unknown. Lynsight offers a new way to test for Lynch syndrome that shines a light on the functional problem — and enlightens the path ahead. DiagMMR will be introduced into the US market once the clinical validation studies are completed.
