BACKGROUND: Diabetes mellitus (DM) has long been recognized as a risk factor for pancreatic cancer (PaC) and recently has attracted attention as a manifestation of PaC. Diabetes is expected to be a clue for the early detection of PaC; however, no effective screening strategy has been established.
METHODS: Forty diabetic patients with PaC were identified and compared with 120 diabetic patients without any malignancies. We analyzed risk factors for and early signs of PaC, focusing on the DM-onset age.
RESULTS: As there were peaks at 40-45 years and 60-65 years in the distribution of DM-onset age, we analyzed the clinical characteristics of and risk factors for PaC according to DM-onset age: i.e., early-onset (< 55 years) and late-onset (≥ 55 years). PaC was diagnosed within 2 years of DM onset (new-onset) in 0% of the patients with early-onset DM, and in 33% of those with late-onset DM. The mean duration of DM in patients with early-onset DM with PaC was longer than that in the late-onset patients (26 vs. 9 years; P < 0.01). A family history of DM (odds ratio [OR] 3.60) and use of insulin (OR 3.52) were significant risk factors in patients with early-onset DM, while the onset age of DM (OR 1.12) and multiple diabetic patients in the family (OR 6.13) were risk factors in those with late-onset DM. Body weight loss and exacerbation of DM were seen 12 months prior to PaC diagnosis in both groups.
CONCLUSIONS: Our study revealed specific risk factors for and similar early signs of PaC in early-onset and late-onset DM. Thus, we could develop a screening strategy, combining these risk factors specific for DM-onset age with early signs of disease.
