2. patients with pancreatic cancer confirmed by pathology;
3. Patients without a second primary tumor;
4. The clinical diagnostic information to be collected within three months before sampling is relatively complete.

2. hepatitis B surface antigen positive, hepatitis C antibody positive, HIV antibody positive or syphilis antibody positive;
3. Those who have participated in other clinical trials of drugs and accepted clinical trials of drugs or devices for trial within the first three months;
4. Those vaccinated with active or attenuated vaccine within 1 month before screening or during the planned trial;
5. Pregnant or lactating women;
