Dr. Ruth (Douglas) Etzioni is a Full Member in Biostatistics of the Division of Public Health Sciences at the Fred Hutchinson Cancer Research Center. Her work focuses on the development and implementation of statistical methods for prostate cancer studies. In the past, she has worked on assessing the efficacy of prostate specific antigen (PSA) screening from population studies, estimating the frequency of overdiagnosis associated with PSA, evaluating novel prostate cancer biomarkers, and tracking patterns and outcomes of prostate cancer care. Her work in prostate cancer surveillance is conducted as part of the Cancer Intervention and Surveillance Modeling Network (CISNET). Click link for more information on the projects.
As leader of the biostatistics core for the Northwest Prostate Cancer Specialized Program of Research Excellence (SPORE), Dr. Etzioni has developed methods for analyzing immunohistochemical studies, and combining results from microarray experiments, while working with SPORE investigators to select the most appropriate design and analysis approaches for a broad array of studies. She is an affiliate investigator on the Data Management Coordination Center for the Early Detection Research Network (EDRN) and continues to work with EDRN statisticians on methods for biomarker development. Dr. Etzioni is starting a project to build a computerized decision tool for the development of clinical practice guidelines for prostate cancer screening (Guidelines). In addition to these projects, her current interests include modeling the development of resistance to androgen ablation therapy.
