I am a surgical oncologist who specializes in treating patients with pancreatic cancer. My expertise includes both open and minimally invasive surgical techniques. I am also the medical director for the Continuous Performance Improvement Department at Fred Hutch. In this role, I help ensure the quality and safety of our health care service. I am a fellow of the American College of Surgeons and a member of the Society of Surgical Oncology, the American Association for Cancer Research and the American Association of Immunologists.

In the lab, I study the body’s immune response to pancreatic cancer as well as other solid tumors. Data suggests that pancreatic cancer may not only be evading the immune system, but actually getting assistance from it. Recently, my colleagues and I have found that the right combination of immunotherapy drugs prompts cells in the immune system to kill tumor cells. Our hope is to continue enhancing the body’s immune response within the tumor microenvironment.

Dr. Yeh is a professor in the Departments of Surgery and Pharmacology at the University of North Carolina (UNC) at Chapel Hill, Vice Chair of Research in the Department of Surgery, and co-Director of Clinical Research at the UNC Lineberger Comprehensive Cancer Center. She joined the faculty at UNC in 2005 and was recently named an Oliver Smithies Investigator (honoring the late Nobel Prize winner at UNC). She maintains an active clinical practice specializing in endocrine diseases (thyroid, parathyroid, adrenal) and pancreatic cancers. Her research focus centers on the use of genomics to identify new approaches for pancreatic cancer.

Dr. Yeh received her medical degree from Johns Hopkins University and completed her general surgery residency at the Boston Medical Center, a research fellowship at Dana-Farber Cancer Institute, and a surgical oncology fellowship at the Memorial-Sloan Kettering Cancer Center.

In 2015, Dr. Yeh identified new molecular subtypes of pancreatic cancer that have clinical and treatment significance. To translate molecular subtypes to the clinic, her group developed a single sample classifier that is now licensed to GeneCentric Therapeutics. Dr. Yeh and her collaborators also have developed a device that could help drive chemotherapy drugs directly into pancreatic tumor tissue to prevent their growth and shrink them. Dr. Yeh co-founded Advanced Chemotherapeutic Technologies, Inc. in order to bring the device into clinical trials.
