Pancreatic Cancer and Diabetes Mellitus

Prospective Cohort Study on Endo-Exdo Secretory Function Alterations and All-round Outcomes After Pancreatic Cancer

The goal of this observational study is to learn about post-surgery of pancreatic cancer diabetes mellitus.The main questions it aims to answer are:

1. Are the incident rates of glucose metabolic disorders (pre-diabetes and diabetes mellitus) after pancreatic cancer of different etiologies the same?
2. Are alterations in endocrine and exdocrine secretory function in patients with pancreatic surgery associated with all-round outcomes? All patients with pancreatic surgery have been given the standardized treatment for the condition.

The reasearchers will summarize the incident rates of glucose metabolic disorders (pre-diabetes and diabetes mellitus) during different surgical procedures to explore the association between alternations in endocrine and exdocrine secrectory function and all-round outcomes.

Investigators will prospectively collect data from patients with pancreatic cancer after surgery in participant centers.

Inclusion Criteria:

Age ≥ 18 years; 3. patients with pancreatic cancer who are proposed to undergo pancreatectomy by pancreaticobiliary surgery at our hospital; 4. those who voluntarily completed the Pancreatobiliary Surgery Cohort Study and signed the informed consent; 5. those who have completed and banked serum and pathological specimens at our hospital.
