Pancreatic Cancer Detection Consortium (PCDC) Prospective Cohorts

Pancreatic Cancer Detection Consortium (PCDC) Prospective Cohorts

This study evaluates individuals without pancreatic cancer, but who have been determined to be at higher-than-average lifetime risk of developing pancreatic cancer to help detect pancreatic cancer or other cancers at an earlier time when they might be more easily treated and cured.

PRIMARY OBJECTIVES:

I. To develop a cohort (biobank of biospecimens and data) of subjects without pancreatic cancer who are at highrisk for pancreatic cancer due to: a strong family history, a mutation in a known pancreatic cancer predisposition gene, or fukuoka worrisome or high-risk pancreatic cysts.

II. To follow the cohort subjects longitudinally and collect biospecimens and follow-up data and record medical outcomes.

III. To make biospecimen available to PCDC-approved projects to validate potential biomarkers for performance using nested case-control prospective designs.

OUTLINE: This is an observational study.

Participants undergo blood sample collection, complete questionnaires, have their medical records reviewed and undergo pancreatic cyst fluid collection during standard of care endoscopic ultrasounds fine needle aspiration.

Inclusion Criteria:

      • OR 2+ affected first degree relatives [(FDR), defined as blood related parents, siblings, or children]

    • Known pathogenic/likely pathogenic (P/LP) mutation in at least one of the following:
