The exposome as a target for primary prevention and a tool for early detection of pancreatic cancer

Abstract

Pancreatic Ductal Adenocarcinoma (PDAC) is a highly aggressive malignancy with limited survival due to late stage diagnosis and scarce therapeutic options. Emerging evidence highlights the role of the "exposome," which encompasses environmental, lifestyle, and metabolic exposures, as a crucial determinant in PDAC risk and a potential avenue for early detection. This review synthesizes findings on modifiable risk factors, including smoking, obesity, diabetes, diet, and alcohol consumption, and their interplay with genetic and metabolic profiles in PDAC development. Additionally, we explore cutting-edge approaches in exposomic research, such as biobanking, electronic health record analysis, and AI-driven predictive models, to identify early biomarkers and stratify high-risk populations. This integrated framework aims to inform prevention strategies and improve early detection of PDAC.
