    Diabetes, Pancreatogenic Diabetes, and Pancreatic Cancer
    (American Diabetes Association, 2017-05) Andersen, Dana K.; Korc, Murray; Petersen, Gloria M.; Eibl, Guido; Li, Donghui; Rickels, Michael R.; Chari, Suresh T.; Abbruzzese, James L.; Medicine, School of Medicine
    The relationships between diabetes and pancreatic ductal adenocarcinoma (PDAC) are complex. Longstanding type 2 diabetes (T2DM) is a risk factor for pancreatic cancer, but increasing epidemiological data point to PDAC as also a cause of diabetes due to unknown mechanisms. New-onset diabetes is of particular interest to the oncology community as the differentiation of new-onset diabetes caused by PDAC as distinct from T2DM may allow for earlier diagnosis of PDAC. To address these relationships and raise awareness of the relationships between PDAC and diabetes, a symposium entitled Diabetes, Pancreatogenic Diabetes, and Pancreatic Cancer was held at the American Diabetes Association's 76th Scientific Sessions in June 2016. This article summarizes the data presented at that symposium, describing the current understanding of the interrelationships between diabetes, diabetes management, and pancreatic cancer, and identifies areas where additional research is needed.

    Endoscopic Ultrasound and Related Technologies for the Diagnosis and Treatment of Pancreatic Disease - Research Gaps and Opportunities: Summary of a National Institute of Diabetes and Digestive and Kidney Diseases Workshop
    (Lippincott, Williams & Wilkins, 2017) Lee, Linda S.; Andersen, Dana K.; Ashida, Reiko; Brugge, William R.; Canto, Mimi I.; Chang, Kenneth J.; Chari, Suresh T.; DeWitt, John; Hwang, Joo Ha; Khashab, Mouen A.; Kim, Kang; Levy, Michael J.; McGrath, Kevin; Park, Walter G.; Singhi, Aatur; Stevens, Tyler; Thompson, Christopher C.; Topazian, Mark D.; Wallace, Michael B.; Wani, Sachin; Waxman, Irving; Yadav, Dhiraj; Singh, Vikesh K.; Medicine, School of Medicine
    A workshop was sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases to address the research gaps and opportunities in pancreatic endoscopic ultrasound (EUS). The event occurred on July 26, 2017 in 4 sessions: (1) benign pancreatic diseases, (2) high-risk pancreatic diseases, (3) diagnostic and therapeutics, and (4) new technologies. The current state of knowledge was reviewed, with identification of numerous gaps in knowledge and research needs. Common themes included the need for large multicenter consortia of various pancreatic diseases to facilitate meaningful research of these entities; to standardize EUS features of different pancreatic disorders, the technique of sampling pancreatic lesions, and the performance of various therapeutic EUS procedures; and to identify high-risk disease early at the cellular level before macroscopic disease develops. The need for specialized tools and accessories to enable the safe and effective performance of therapeutic EUS procedures also was discussed.

    PROspective Evaluation of Chronic Pancreatitis for EpidEmiologic and Translational StuDies: Rationale and Study Design for PROCEED From the Consortium for the Study of Chronic Pancreatitis, Diabetes, and Pancreatic Cancer
    (Wolters Kluwer, 2018-11) Yadav, Dhiraj; Park, Walter G.; Fogel, Evan L.; Li, Liang; Chari, Suresh T.; Feng, Ziding; Fisher, William E.; Forsmark, Christopher E.; Jeon, Christie Y.; Habtezion, Aida; Hart, Phil A.; Hughes, Steven J.; Othman, Mohamed O.; Rinaudo, Jo Ann; Pandol, Stephen J.; Tirkes, Temel; Serrano, Jose; Srivastava, Sudhir; Van Den Eeden, Stephen K.; Whitcomb, David C.; Topazian, Mark; Conwell, Darwin L.; Medicine, School of Medicine
    Prospective Evaluation of Chronic Pancreatitis for Epidemiologic and Translational Studies (PROCEED) is the first prospective, observational cohort study of chronic pancreatitis (CP) in the United States. The primary goals of PROCEED are to define disease progression, test the predictive capability of candidate biomarkers, and develop a platform to conduct translational and mechanistic studies in CP. Using objective and consensus-driven criteria, PROCEED will enroll adults at different stages of CP-controls, suspected CP, and definite CP. In addition to collecting detailed information using structured case report forms and protocol-mandated evaluations at baseline and during follow-up, PROCEED will establish a linked biorepository of blood, urine, saliva, stool, pancreatic fluid, and pancreatic tissue. Enrollment for PROCEED began in June 2017. As of July 1, 2018, nine clinical centers of the Consortium for the Study of Chronic Pancreatitis, Diabetes, and Pancreatic Cancer are enrolling, and 350 subjects have completed baseline evaluation. In conclusion, PROCEED will provide the most accurate and reliable estimates to date on progression of CP. The established cohort and biorepository will facilitate numerous analyses, leading to new strategies for diagnosis, methods to monitor disease progression, and treatment of CP.

    A Prospective Study to Establish a New-Onset Diabetes Cohort: From the Consortium for the Study of Chronic Pancreatitis, Diabetes, and Pancreatic Cancer
    (Wolters Kluwer, 2018-11) Maitra, Anirban; Sharma, Ayush; Brand, Randall E.; Van Den Eeden, Stephen K.; Fisher, William E.; Hart, Phil A.; Hughes, Steven J.; Mather, Kieren J.; Pandol, Stephen J.; Park, Walter G.; Feng, Ziding; Serrano, Jose; Rinaudo, Jo Ann; Srivastava, Sudhir; Chari, Suresh T.; Medicine, School of Medicine
    The National Cancer Institute and the National Institute for Diabetes and Digestive and Kidney Diseases initiated the Consortium for the Study of Chronic Pancreatitis, Diabetes, and Pancreatic Cancer (CPDPC) in 2015 (the CPDPC's origin, structure, governance, and research objectives are described in another article in this journal). One of the key objectives of CPDPC is to assemble a cohort of 10,000 subjects 50 years or older with new-onset diabetes, called the NOD cohort. Using a define, enrich, and find early detection approach, the aims of the NOD study are to (a) estimate the 3-year probability of pancreatic ductal adenocarcinoma (PDAC) in NOD (define), (b) establish a biobank of clinically annotated biospecimens from presymptomatic PDAC and control new-onset type 2 diabetes mellitus subjects, (c) conduct phase 3 validation studies of promising biomarkers for identification of incident PDAC in NOD patients (enrich), and (d) provide a platform for development of a future interventional screening protocol for early detection of PDAC in patients with NOD that incorporates imaging studies and/or clinical algorithms (find). It is expected that 85 to 100 incidences of PDAC will be diagnosed during the study period in this cohort of 10,000 patients.

    Type 3c (pancreatogenic) diabetes mellitus secondary to chronic pancreatitis and pancreatic cancer
    (Elsevier, 2016-11) Hart, Phil A.; Bellin, Melena D.; Andersen, Dana K.; Bradley, David; Cruz-Monserrate, Zobeida; Forsmark, Christopher E.; Goodarz, Mark O.; Habtezion, Aida; Korc, Murray; Kudva, Yogish C.; Pandol, Stephen J.; Yadav, Dhiraj; Chari, Suresh T.; Consortium for the Study of Chronic Pancreatitis, Diabetes, and Pancreatic Cancer(CPDPC); Medicine, School of Medicine
    Diabetes mellitus is a group of diseases defined by persistent hyperglycaemia. Type 2 diabetes, the most prevalent form, is characterised initially by impaired insulin sensitivity and subsequently by an inadequate compensatory insulin response. Diabetes can also develop as a direct consequence of other diseases, including diseases of the exocrine pancreas. Historically, diabetes due to diseases of the exocrine pancreas was described as pancreatogenic or pancreatogenous diabetes mellitus, but recent literature refers to it as type 3c diabetes. It is important to note that type 3c diabetes is not a single entity; it occurs because of a variety of exocrine pancreatic diseases with varying mechanisms of hyperglycaemia. The most commonly identified causes of type 3c diabetes are chronic pancreatitis, pancreatic ductal adenocarcinoma, haemochromatosis, cystic fibrosis, and previous pancreatic surgery. In this Review, we discuss the epidemiology, pathogenesis, and clinical relevance of type 3c diabetes secondary to chronic pancreatitis and pancreatic ductal adenocarcinoma, and highlight several important knowledge gaps.
