Researchers have developed a new test to measure a protein QSOX1 that is found to be elevated in subjects with pancreas cancer. Researchers are looking to use this test to compare subjects with pancreas cancer and subjects without pancreas cancer to see if this test could be used to diagnosis pancreas cancer.

Inclusion Criteria:

• Adult patients with biopsy-proven adenocarcinoma prior to receiving any therapy such as surgery, radiation or chemotherapy.
• Patients without pancreas cancer.
• Adult patients with benign pancreas disorders such as pancreatitis with imaging within 12 months (CT, MRI, EUS) documenting no cancer.
• Healthy adults with blood specimens in an existing biobank.
• Patients with pancreatic cystic lesions.
• Adult patients undergoing clinically indicated EUS-guided FNA biopsy of pancreatic cystic lesions.

Exclusion Criteria:

• Prior treatment for pancreas cancer.
• Unable or unwilling to give consent.
