About the Provider

Dr. Claudine Isaacs is the co-director of the Breast Cancer Program and Medical Director of the Jess and Mildred Fisher Center for Hereditary Cancer and Clinical Genomics Research at the Lombardi Comprehensive Cancer Center.
Dr. Isaacs' extensive research covers all aspects of breast cancer, including cancer risk assessment, and novel prevention, screening and medical management strategies for women at high risk for breast cancer. Toward that end, she has served as the principal investigator (PI) or co-investigator for numerous clinical trials and grants exploring potential new treatments for early-stage and metastatic breast cancer. Dr. Isaacs also was a PI for the Cancer Genetics Network site and for the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Lombardi was one of 10 sites nationwide that enrolled patients for this trial.
Dr. Isaacs has authored over 185 peer-reviewed publications, numerous book chapters and served as editor for a seminal textbook on hereditary breast cancer, published in 2007. Professionally, she has been a member of the Cancer Education Committee and Scientific Program Committee at the American Society of Cancer Oncology, and the Breast Oncology Local Diseases Task Force of the Breast Steering Committee of the National Cancer Institute, among others.
Dr. Isaacs received her medical degree and 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 Lombardi faculty in the Department of Medicine (Division of Hematology and Medical Oncology) where she now is also a Professor of Medicine and Oncology.
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 experts 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 as she/he navigates the cancer journey.
