Dr. Ruth Etzioni is a biostatistician who primarily focuses on cancer screening and early detection. Much of her work is in the area of prostate and breast cancer, where she develops methods for evaluating diagnostic tests; creates mathematical models to reflect the impact of screening tests on the incidence and mortality rates of these cancers; calculates costs and benefits of preventive screening; tracks population trends with regard to screening and related behaviors and works with investigators on trial design and analysis. Dr. Etzioni also researches overdiagnoses associated with certain screening tests — when screening finds cancers that would not cause symptoms or death within a patient’s natural lifetime. She also evaluates novel cancer biomarkers and tracks patterns and outcomes of cancer care. Dr. Etzioni leads the biostatistics core for the National Cancer Institute-funded multicenter Northwest Prostate Cancer Specialized Program of Research Excellence, or SPORE, and she has a longstanding interest in researching, tracking and working to eliminate health disparities.
