摘要Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest malignancies, accounting for 95% of pancreatic cancer cases, with a 5-year survival rate of around 10%. The relationship between pancreatitis and pancreatic cancer has been noted within the medical community. Recent epidemiological data and findings from experimental mouse models have underscored pancreatitis as a critical risk factor for pancreatic cancer. Therefore, exploring the mechanisms underlying the transition from pancreatitis to pancreatic cancer is crucial for improving early detection and treatment strategies for pancreatic cancer. In this review, we conducted a comprehensive search of the PubMed database and discussed relevant original studies, focusing on 3 key areas: findings from population- and animal-based studies, the role of pancreatic epithelial cell-intrinsic factors, and the impact of immune cells and cytokines. Additionally, we offered our prospectives on possible future research directions.
