About this trial
The goal of this observational study is to test in patients with cystic tumor of pancreas. The main questions it aims to answer are:
Screening of molecular diagnostic markers for pancreatic cystic tumors by cfDNA methylation sequencing of pancreatic cystic fluid and proteomic assays to distinguish benign from malignant and mucinous/non-mucinous, correlate with pathological features, and find molecular features associated with the degree of malignancy.
Participants will Provide post-operative cyst fluid specimens.
Eligibility criteria
Qualifiers
Subjects are ≥ 18 years old, regardless of gender;
Preoperative imaging examination (EUS, CT, MRI) diagnosed cystic mass of pancreas and suspected cystic tumor;
Subjects voluntarily accepted radical resection of pancreatic cystic tumors;

Disqualifiers
The excised sample does not contain cystic components, or the cystic fluid cannot be collected;
Receive tumor-related treatment (radiotherapy, chemotherapy, immunotherapy, etc.) before operation;
Receive antibiotic treatment within 1 week before operation;
Subjects refused to accept radical resection of pancreatic cystic tumor, or had any situation that they could not accept radical resection of pancreatic cystic tumor;
