New tumor biopsies are not required for entrance into the Registry. BRCAmut PDAC Group: Study Group B: non-Ashkenazi Jewish descent * Know n BRCA mutation carrier. * Histologic proof of primary pancreatic ductal adenocarcinoma. * May have either potentially curable (resectable) primary PDAC, localized but unresectable primary PDAC, or metastatic (stage IV) PDAC. * Prior personal history of other malignancy; either prior or currently active, including breast, ovarian, or prostate cancer is allowed. * Both previously treated and previously untreated patients are eligible. Previous treatment may include surgical resection, regional radiation therapy, or systemic therapy. Patient may be receiving active therapy. * Willing to provide blood specimens for correlative studies. * Willing to provide permission to obtain banked tumor tissue for analysis (previous biopsies or surgical material).
