Predictive Factors for Differentiating Pancreatic Cancer-Associated Diabetes Mellitus from Common Type 2 Diabetes Mellitus for the Early Detection of Pancreatic Cancer.

Background: The purpose of this study was to find the factors that may be helpful for differentiating pancreatic cancer-associated diabetes mellitus (PC + DM) from common type 2 diabetes for the early diagnosis of pancreatic cancer.

Methods: From January 2008 to August 2013, 171 patients with pancreatic cancer and new-onset diabetes were recruited for the study; 242 age- and gender-matched patients with common type 2 diabetes were also identified as control during the same period. The patient's characteristics and laboratory parameters were compared between the 2 groups.
