Solving for Breast Cancer Disparities with Scott Siegel, PhD, and Dr. Dawn Leonard
12/28/23 • 16 min
Breast cancer is the second most common cancer among women in America - accounting for 1 in 3 new cancer diagnoses each year. And while there isn’t a big difference across races in terms of rates of getting breast cancer - there are huge gaps in what happens after diagnosis.
In this episode we sit down with Scott Siegel, Ph.D., director of cancer control and population sciences at ChristianaCare, and Dr. Dawn Leonard, chief of ChristianaCare's division of breast surgery, to discuss that alarming disparity.
They shed light on the urgent issues at play, including higher rates of advanced breast cancer and the aggressive triple negative breast cancer prevalent in Delaware. They explain how a victory in eliminating a racial disparity for a completely different form of cancer is spurring the call to action to address breast cancer. And we discuss how success in Delaware could apply nationwide.
Scott Siegel, Ph.D., is a psychologist and director of Population Health Research at ChristianaCare. In this role Siegel works collaboratively with multidisciplinary teams in the health system and with governments, universities, and community-based organizations to improve population health.
Dawn Leonard, MD, FACS, specializes in breast surgery at ChristianaCare. Dr. Leonard joined ChristianaCare with more than 17 years of practice and leadership experience, most recently at Georgetown University Hospital and as the site director at a community hospital with a Regional Breast Health Program. Dr. Leonard has earned multiple recognitions as a "Top Doc" in Breast Surgery and awards for excellence in healthcare, service and scholarship.

Patient-Centered Gene Editing with Eric Kmiec, Ph.D.
This past week the FDA for the first time approved use of a gene editing-based therapy. The new treatment is for people with Sickle Cell Disease. Gene editing has the potential to transform so many areas of medicine. ChristianaCare's Gene Editing Institute is the only institute of its kind in the nation at a community-based health system, which has led GEI to take a unique approach to gene editing research.
On this week's episode, we talk with Eric Kmiec, Ph.D., Executive Director and Chief Scientific Officer at ChristianaCare's Gene Editing Institute, about the patient-centered approach his researchers take. We find out what factors the team considers first when determining what to study and learn what that means for the development of new medicines to treat cancer and inherited diseases.
Join us for a great conversation on the past, present and future of gene editing - what is working, what is not, what opportunities there are beyond medicine and so much more.
Eric Kmiec, Ph.D., is executive director and chief scientific officer at ChristianaCare's Gene Editing Institute. He is also co-founder and chief scientific officer of CorriXR Therapeutics. Widely recognized for his pioneering work in the fields of molecular medicine and gene editing, Dr. Kmiec has developed CRISPR based genetic therapies for Sickle Cell Disease and Non-Small Cell Lung Cancer. He is also Editor-in-Chief of the journal, Gene and Genome Editing.
