cfDNA methylation sequencing and proteome analysis
What this trial is about
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.
