Pancreas Registry and High Risk Registry

The overall purpose of this research project is to establish a registry of patients with pancreatic diseases. Patients included in the registry may include those with: pancreatic cancer, precancerous lesions of the pancreas such as intraductal papillary mucinous neoplasms (IPMNs) and cystic lesions, inflammatory lesions and inflammation of the pancreas, and patients at high-risk of pancreatic cancer such as those with a family history of pancreatic cancer or with a family history of a syndrome known to be associated with pancreatic cancer. The data contained in this registry will be used to conduct research related to the risk of pancreatic cancer and pancreatic diseases. As this is a registry protocol, no specific hypotheses are to be tested.

Specific Aims:

1. Establish and maintain a registry of individuals and their family members who have pancreatic diseases and may be at increased risk of developing pancreatic cancer over normal population risk. 2. Collect data and review existing data on personal and family histories, demographics, risk factors, and health behaviors. 3. Use the data in the registry to conduct studies related to disease risk, prevention, and prognosis of pancreatic cancer and other pancreatic diseases.

Pancreatic cancer is the fourth leading cause of death from malignancy in the United States. With near equivalent incidence and mortality, cure can only be achieved with surgical resection of an early stage lesion. Premalignant disease stages, such as IPMN, may be detected with noninvasive and minimally invasive techniques, providing an opportunity for screening and surveillance of at-risk populations.

Knowledge of the etiology of pancreatic cancer is incomplete. Approximately 10% of pancreatic ductal adenocarcinoma (PDAC) has a hereditary component, and screening this population has the potential to have an impact on disease mortality. Certain patient populations, such as those with hereditary pancreatitis, Peutz-Jeghers syndrome, familial atypical multiple mole melanoma (FAMMM syndrome), Lynch syndrome, and the breast ovarian cancer syndrome (BRCA1 and BRCA2 mutations) are at the highest risk of PDAC. BRCA2 mutations are the most commonly identified germline mutations in families with PDAC. Even a family history of PDAC without the above described syndromes has been shown to increase risk, suggesting a unique familial pancreatic cancer syndrome which may be related to the partner and localizer of BRCA2 (PALB2) gene or other PDAC susceptibility genes. Environmental risk factors, such as cigarette smoking, diabetes, obesity and dietary risk factors have been implicated in the development of PDAC.

A sequential model of acquisition of somatic mutations via a Pancreatic Intraepithelial Neoplasia (PanIN) has been proposed for the development of PDAC and subsequent metastases. However, others have proposed that the metastatic process may be initiated earlier in the disease process during the pre-malignant cyst or PanIN phase. This may in part account for the fact that the overwhelming majority of patients diagnosed with PDAC are diagnosed when the lesion is already metastatic.

Several groups have instituted PDAC screening for individuals at high-risk of PDAC. These groups have demonstrated the feasibility of detection of PDAC and pre-malignant lesions in certain high-risk individuals. Given the large gaps in knowledge, recruitment of patients with preneoplastic pancreatic diseases to registries is essential in the development of effective PDAC screening and prevention programs.

As an increasing number of patients undergo cross-sectional imaging with the abdomen with cat scan (CT) and magnetic resonance imaging (MRI), an increasing number of patients are found to have pancreatic disease and pancreatic cysts. While there is an increased risk of pancreatic cancer with these lesions, the studies to date are small and retrospective.
