Chronic Pancreatitis, Pancreatic Cancer
Conditions
Brief summary
The investigators plan to collect throat swabs, saliva, feces and serum samples from pancreatic cancer patients, chronic pancreatitis patients and healthy people and clarify the characteristics of oral flora and serum metabolome of pancreatic cancer patients.

Eligibility
Inclusion criteria
1.Pathologic diagnosis of pancreatic ductal adenocarcinoma;Diagnosis of CP defined as having obvious morphological features of CP (i.e., the presence of pancreatic calcifications on CT scan and/or magnetic resonance cholangiopancreatography);Other benign disease populations without pancreatic lesions.
Exclusion criteria
1. Pregnant women. 2. Patients with coagulation disorders who are unable to undergo blood tests. 3. Have a history of using antibiotics or probiotics within the past 3 months.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| serum metabolites | Baseline | Perform Untargeted liquid chromatography-tandem mass spectrometry (LC-MS/MS) to analyse serum samples collected from pancreatic cancer patients, chronic pancreatitis patients and healthy people. |
| Gastrointestinal microbiota | Baseline | Perform 16S RNA sequence and shotgun metagenomic analysis of fecal, throat swabs and salivary samples collected from pancreatic cancer patients, chronic pancreatitis patients and healthy people. |
| Overall Survival | up to 2 years | The length of time (in days) from study enrollment that participants remain alive. |
| Predictive model | up to 2 years | Combined with preoperative imaging and pathological information, a predictive model of pancreatic cancer would be established based on the metabolic and microbiota difference. Verify the stability and accuracy of our model in larger cohorts and promote clinical translation. |
