EULAT Eradicate GBC (EULAT)

May 30, 2024 updated by: Institut de cancérologie Strasbourg Europe

Establishment and Exploitation of a European-Latin American Research Consortium Towards Eradication of Preventable Gallbladder Cancer - EULAT Eradicate GBC

Gallstones are relatively frequent in women and constitute one of the main risk factors for gallbladder cancer (GBC).

Currently, GBC diagnosis is mainly based on imaging (ultrasound or abdominal CT) associated with invasive examinations (biopsy and surgery), with no marker available to date to accurately predict risk and diagnose the disease early. The only curative treatment for GBC remains surgery with complete resection of tumors in early stages.

Given the aggressiveness of GBC and the very limited therapeutic options, as well as the possibility of preventing GBC by cholecystectomy during the 10 to 20 years required for the development of gallbladder tumors, it is imperative to develop effective and efficient prevention strategies based on a prioritization of interventions according to environmental and genetic-molecular risk factors.

The investigators aim to identify epidemiological factors linked to the development of GBC, and to identify, validate and functionally characterize genetic-molecular markers in blood, saliva, urine, bile and stool that allow risk prediction, early diagnosis and precision treatment of incidental tumors.

Detailed Description

Gallbladder cancer (GBC) is a neglected disease with huge potential for prevention. This study aims at significantly improving the accuracy of risk estimation and early detection of GBC by identifying and adequately considering geographical, environmental, lifestyle, ethnic, gender and molecular differences. The investigators plan to generate the information needed to establish and refine current prevention programmes, including the primary, secondary and tertiary prevention of GBC. The investigators will (1) build a unique European-Latin American GBC biorepository integrated into a tailored IT platform, (2) identify, validate and functionally characterize novel GBC biomarkers, (3) develop a multifactorial risk score that integrates established and newly identified epidemiological and molecular risk factors, (4) improve the understanding of the causal mechanisms that link lifestyle, cultural and behavioural factors to GBC development, (5) unravel novel opportunities for the targeted therapy of incidental GBC, (6) exploit existing and newly generated epidemiological and multi-omics data to improve the accuracy of GBC risk prediction and (7) contribute to the training of the next generation of Latin American researchers in precision medicine for GBC. The generated information will permit identification of individuals at high GBC risk, guiding surveillance and individual decisions on the possible benefit of preventive gallbladder removal in regions of low and high GBC incidence. Novel data on genomic alterations in incidental GBC will pave the way towards implementation of future clinical trials. The planned European-Latin American GBC biorepository and IT platform will constitute a prime resource for translational research on individualized prevention, personalized early detection and targeted therapy of GBC. The participation in our project of representatives of health authorities, patients and the industry guarantee the efficient incorporation of project results into national health policies.
