About me
Dr. Claudine Isaacs is a medical oncologist who specializes in the care of women with all stages of breast cancer. She is Professor of Medicine and Oncology, Associate Director of Clinical Research and Leader of the Clinical Breast Cancer Program at the Georgetown Lombardi Comprehensive Cancer Center. She is also the Medical Director of the Jess and Mildred Fisher Center for Hereditary Cancer and Clinical Genomics Research. She has been practicing for over 20 years.
Dr. Isaacs received her medical degree and internal medicine residency training at McGill University, Canada. She completed fellowship training in the Division of Hematology and Oncology at McGill University and a Fellowship in Breast Medical Oncology in the Division of Medical Oncology at Georgetown University. She then joined the faculty in the Department of Medicine and Oncology at Georgetown University.
Dr. Isaacs has extensive experience in the conduct of clinical trials focusing on all aspects of breast cancer. Additional research interests include cancer risk assessment and medical management and prevention strategies for women at high risk for breast cancer. She has served as the principal investigator of a variety of clinical trials in the treatment of early-stage and metastatic breast cancer, and currently serves as the principal investigator of the Translational Breast Cancer Research Consortium (TBCRC), the ISPY2 trial at Georgetown University. She has authored over 200 peer-reviewed publications. She has also served on a number of committees, including the Cancer Education Committee at the American Society of Clinical Oncology (ASCO), the ASCO Scientific Program Committee, the Breast Oncology Local Diseases Task Force of the Breast Steering Committee of the National Cancer Institute, and most recently the ASCO guidelines committee. She has been named one of America's Top Cancer Doctors by Castle Connolly/Newsweek for many years running, and has also received designations from Washingtonian Magazine and Women's Health Magazine.
Dr. Isaacs' Philosophy of Care:
I strive to personalize the care of my patients by tailoring state-of-the-art therapy to their individual situations and by providing them with access to cutting-edge clinical trials. Equally important is that the care of my patients extends well beyond focusing just on the optimal therapy of their cancer. My approach to care is to relate to each of my patients as individuals in the context of their lives, and not solely based on the characteristics of their disease. To that end, I work with a wonderful and dedicated multidisciplinary group of expert colleagues who are deeply committed to and involved with our patients' care. The whole team is focused solely on breast cancer and includes medical oncologists, surgeons, radiation oncologists, breast imagers, and pathologists who are supported by an experienced team of clinical nurse coordinators, nurse navigators, research nurses, genetic counselors and social workers, all championing a multidisciplinary approach to breast cancer diagnosis, treatment and recovery. We are not treating a disease. We are treating a person and we are here to provide state-of-the-art medical treatment and to accompany that person navigates their cancer journey.
