Abstract

Objectives Diabetes mellitus (DM) is prevalent with pancreatic ductal adenocarcinoma (PDAC). Importantly, new-onset DM is characteristic of the disease and could be an early sign of PDAC. The clinical outcome of PDAC with new-onset DM may differ from that in patients without DM or long-standing DM. Methods We retrospectively reviewed medical records of PDAC patients who underwent curative resection between 2006 and 2014. New-onset DM was defined as a diagnosis of DM within 24 months before the diagnosis of PDAC. Survival analysis and Cox regression were performed to evaluate oncologic outcomes. Results No significant differences in clinical characteristics were found in 3 groups. Overall survival of patients with new-onset DM was worse than non-DM (22 vs 33 months, P = 0.039). New-onset DM was highly associated with early recurrence (hazard ratio, 1.451; 95% confidence interval, 1.054-1.999; P = 0.022). Poor oncologic outcome of new-onset DM was more pronounced in low T stage patients (overall survival in low vs high T stage, 33 vs 18 months; P = 0.129). Conclusions Pancreatic ductal adenocarcinoma with new-onset DM has worse oncologic outcomes than non-DM or long-standing DM. These results suggest that new-onset DM represents aggressive tumor biology, especially in the early stage of PDAC.
