Genomic Profiling of Pancreatic Cystic Tumors

This study aims to find out whether quantitative and qualitative analysis, including genetic mutation analysis, of samples obtained from patients with pancreatic cysts is associated with the risk of malignancy, and helpful in the differential diagnosis of mucinous and serous cysts. The study design is a single-arm prospective cohort observational study. Using blood, pancreatic cyst fluid, and pancreatic cyst tissue, genetic mutation analysis and measurement of various biomarkers are performed, and the relationship between these and malignancy or whether they are helpful in distinguishing mucinous and serous cysts is analyzed. The primary outcome is genetic variants of pancreatic cysts associated with malignancy. The secondary outcomes are factors including genetic variants that differentiate mucinous from serous cysts.
