The Latest Clinical Trials and Research
Clinical trials help doctors and scientists find better ways to diagnose, treat, and prevent disease. Individuals who volunteer for clinical trials play an active role in their own health care and help others by advancing medicine. Our doctors make clinical trials a regular part of cancer care to increase overall cancer survival and expedite the development of a cure. At the John Wayne Cancer Institute you can participate in studies led by internationally renowned researchers. If you are interested in a clinical trial, please speak with your provider.

Our History
In the early 1990’s the leaders of the John Wayne Cancer Institute raised the idea of creating a center dedicated to the treatment and research of breast cancer. An extraordinary gift from Joyce Eisenberg Keefer, a dedicated champion for cancer research and treatment, allowed them to bring their vision to fruition and, in 1993, they opened the multidisciplinary breast center at Saint John’s Health Center. Unfortunately, the building that housed the breast center was damaged beyond repair in the 1994 Northridge earthquake. Once again a generous philanthropist, Margie Petersen, stepped in to provide the financial support necessary to rebuild the breast center.
