Dr. Ball is an endocrinologist who is involved in clinical trials and pre-clinical laboratory studies in thyroid cancer. His clinical trials have included protocols for advanced radioiodine-refractory differentiated thyroid cancer and medullary thyroid cancer. These studies are performed in collaboration with research staff in the upper aero-digestive group in the Sidney Kimmel Comprehensive Cancer Center.
Dr. Ball is associate protocol chair and a member of the Board of Directors of the International Thyroid Oncology Group (ITOG). He's developed national trials through this cooperative group. A focus of these clinical trials is the role of multikinase inhibitors, and inhibitors of the RAS-RAF-MAPK and PI3K pathways.
In pre-clinical research, Dr. Ball collaborates with Dr. Nelkin, Dr. Agrawal and others in the cancer biology division of the Kimmel Cancer Center. The principal areas of this research include pathogenesis and mechanisms of treatment resistance in medullary thyroid cancer, and pathogenesis and immune-directed therapy of anaplastic thyroid cancer. Recent studies have also focused on targeting the RAS-RAF-MAPK and PI3K pathways in differentiated thyroid cancer. This work is supported by the NIH and American Cancer Society.
