ABSTRACT
BACKGROUND: Prior studies have implicated diabetes as a risk factor for pancreatic cancer, yet the impact of diabetes progression on pancreatic cancer incidence remains unclear. We aim to assess pancreatic cancer risk across different stages of diabetes.
METHODS: Employing a predefined search strategy, we conducted a literature review of electronic databases up to 29 February 2024. Extracting odds ratios (OR) and 95% confidence intervals (CIs) relevant to diabetes, we aimed to evaluate pancreatic cancer risk among diabetic patients and conduct subgroup analyses.
RESULTS: Our systematic review comprised 29 observational cohort studies with 25 million participants. We observed a 2.13-fold higher likelihood of pancreatic cancer among diabetic individuals compared with nondiabetic counterparts. Specifically, males with diabetes exhibited a greater pancreatic cancer risk than females; however, regional disparities in pancreatic cancer risk among diabetic patients were NS. Regarding diabetes duration, pooled ORs (95% CI) for pancreatic cancer risk were 2.41 (2.07-2.81) for 1-4 years, 1.67 (1.50-1.85) for 4-10 years, and 2.01 (1.81-2.22) for over 10 years.
CONCLUSION: The results of this study confirm a significant association between diabetes and pancreatic cancer. Although there was no statistically significant difference in risk between different diabetes duration groups, diabetic patients overall face a higher risk of pancreatic cancer. Therefore, diabetic patients should undergo regular pancreatic cancer screening and take appropriate management measures to detect potential pancreatic cancer at an early stage.
