MEET THE SPEAKER
David C. Metz, MD
Professor of Medicine, Perelman School of Medicine
Co-Director Emeritus, University of Pennsylvania Neuroendocrine Tumor Program
After earning his MD from the University of the Witwatersrand's Medical School, Dr. Metz was a resident at both the Albert Einstein Medical Center and the Johannesburg General Hospital. He went on to complete fellowships at Georgetown University Hospital as well as the National Institutes of Health.
Arriving at Penn Medicine in 1993, David Metz, MD, held a variety of leadership roles within the Department of Gastroenterology, including Co-Directorship of the Neuroendocrine Tumor Center and Penn NET Treatment Program. Dr. Metz was previously a staff fellow at the National Institutes of Health, where he performed basic research in pancreatic acinar cell secretion and clinical research in Zollinger-Ellison syndrome. While at Penn Medicine, he served as Chair of the North American Neuroendocrine Tumor Society (NANETS), as a member of the Liaison Committee for Recertification of the American Board of Internal Medicine (American Gastroenterological Association representative), and on the Food and Drug Administration Gastrointestinal Drugs Advisory Committee, among other positions.
Dr. Metz's clinical interests at Penn included Zollinger-Ellison syndrome and other acid-peptic conditions, Helicobacter pylori infection, non-steroidal anti-inflammatory drug gastropathy and the diagnosis and management of patients with functional and non-functional neuroendocrine tumors of the pancreas and alimentary tract. An investigator for a series of prominent clinical trials in all of these areas, Dr. Metz has published more than 200 articles on topics of clinical interest and research. He retired in July 2021 after 28 years at Penn Medicine.
In 2021 Dr. Metz received the NANETS Lifetime Achievement Award that honors an individual who, over the course of their career, has provided outstanding contributions to neuroendocrine disease management through research, clinical practice or educational initiatives, as well as exceptional leadership in NANETS and dedication to its mission.
