Comparative Analysis of Long-Standing and Newly Diagnosed Diabetes Mellitus in Patients with Pancreatic Ductal Adenocarcinoma: A Tunisian Multicenter Study
##plugins.themes.academic_pro.article.main##
Abstract
Introduction: Diabetes mellitus has emerged as a global public health issue due to its increasing prevalence and the increased risk of developing cancers. Pancreatic cancer is believed to be both a consequence of pre-existing diabetes and a potential cause of new-onset diabetes.
Aim: This study aims to compare the characteristics of patients with pancreatic ductal adenocarcinoma and newly diagnosed or long-standing diabetes mellitus.
Methods: A multicentric retrospective study was conducted over 13 years at two university hospitals in Sousse, Tunisia. Included patients had whether a newly diagnosed or a long-standing diabetes mellitus with histologically confirmed pancreatic ductal adenocarcinoma. Statistical analysis using appropriate tests was conducted.
Results: The prevalence of diabetes mellitus was 44.6% among three hundred and seven patients with pancreatic cancer. The male-to-female ratio in patients with pancreatic ductal adenocarcinoma was 2.6:1. Patients’ mean age was 63.9 years, with the majority being over 50 years old. Most patients had no family history of diabetes and exhibited significant weight loss, low body mass index, and uncontrolled diabetes. The comparison between individuals with newly diagnosed diabetes and those with long-standing diabetes revealed numerous similarities, apart from significant differences in drinking patterns (p = 0.03), tumor size (p = 0.018), and smoking in the subgroup of males (p = 0.044).
Conclusion: Patients over 50 with newly diagnosed diabetes mellitus, particularly those who consume alcohol occasionally and men who are not heavy smokers, should undergo further evaluation to identify potential early-stage pancreatic ductal adenocarcinoma
