Aims. The prevalence of diabetes mellitus in pancreatic cancer patients and control subjects was compared. Methods. Retrospective\r\nevaluation of 182 pancreatic cancer patients and 135 controls. The presence of diabetes was evaluated and the time period between\r\nthe diagnosis of diabetes and pancreatic cancer was assessed. A subanalysis based on patient sex was conducted. Results. Diabetes\r\nmellitus was present in 64 patients (35.2%) in pancreatic cancer group and in 27 patients (20.0%) in control group (?2 = 8.709;\r\nP = 0.003). In 18 patients (28.1% of diabetic pancreatic cancer patients) diabetes was new-onset. Diabetes was new-onset in 23.3%\r\nof females compared to 38.1% of males (?2 = 1.537; P = 0.215). The overall prevalence of diabetes was significantly higher among\r\nfemale pancreatic cancer patients (25% versus 43.9%; ?2 = 7.070, P = 0.008), while diabetes prevalence was equally represented in\r\nthe control group patients (22.1% versus 17.2%; ?2 = 0.484, P = 0.487). Conclusion. The prevalence of diabetes mellitus in study\r\ngroup of pancreatic cancer patients was significantly higher when compared to control group. Pancreatic cancer patients with\r\ndiabetes were predominantly females, while diabetes was equally prevalent among sexes in the control group. Therefore, patient\r\nsex may play important role in the risk stratification.
