Fatty Pancreas: Its Potential as a Risk Factor for Pancreatic Cancer and Clinical Implications

Area of Science:

• Gastroenterology and Hepatology
• Endocrinology
• Oncology

Background:

• Incidental findings of pancreatic abnormalities, including fatty pancreas (FP), are rising due to advanced imaging.
• FP, characterized by intra-pancreatic fat deposition, is associated with metabolic syndromes like obesity and diabetes.
• The clinical significance of FP is under investigation, with emerging links to pancreatic carcinogenesis.

Purpose of the Study:

• To explore the association between fatty pancreas and metabolic disorders.
• To investigate the potential role of FP in the development of pancreatic ductal adenocarcinoma (PDAC).
• To discuss the implications of FP in surveillance strategies for high-risk individuals and potential therapeutic interventions.

Main Methods:

• Review of current literature on fatty pancreas, metabolic disorders, and pancreatic cancer.
• Analysis of associations between metabolic syndrome components and FP.
• Examination of evidence linking FP to chronic inflammation, lipotoxicity, and altered pancreatic microenvironment in PDAC development.

Main Results:

• Metabolic disorders such as obesity, insulin resistance, and diabetes are implicated in FP development.
• FP is linked to an increased risk of PDAC, potentially mediated by inflammation and lipotoxicity.
• Pharmacological agents like GLP-1 receptor agonists and SGLT2 inhibitors show promise in reducing pancreatic fat.

Conclusions:

• Fatty pancreas may be a significant factor in pancreatic carcinogenesis and warrants further investigation.
• Incorporating FP assessment into surveillance for individuals at high risk for PDAC could be beneficial.
• Further research is needed to confirm the efficacy of pharmacological interventions in managing FP and its associated risks.
