Risk of Pancreatic Cancer in Patients With Chronic Pancreatitis

Patients with chronic pancreatitis face a significantly increased risk of developing pancreatic cancer compared to individuals without pancreatitis. According to the systematic review and meta-analysis, chronic pancreatitis is associated with a hazard ratio (HR) of 7.82 (95% CI: 5.25–11.65), indicating that the risk is nearly eight times greater for these patients. Chronic pancreatitis poses a higher risk than acute pancreatitis, which has an HR of 3.54 (95% CI: 1.84–6.80). The stronger association with chronic pancreatitis highlights the role of long-term inflammation in the development of pancreatic cancer.

The study also found that the risk is particularly elevated for pancreatic ductal adenocarcinoma (PDAC) (HR: 6.57, 95% CI: 5.31–8.14) and intraductal papillary mucinous neoplasms (IPMN) (HR: 17.19, 95% CI: 8.83–33.46). These findings suggest that chronic pancreatitis may play a critical role in the development of both malignant and precancerous pancreatic lesions.

Given the significant risk, patients with chronic pancreatitis should be considered a high-risk group for pancreatic cancer. This underscores the need for further research into cost-effective screening and monitoring strategies to detect pancreatic cancer or precancerous lesions early in this vulnerable population.
