Janet Stanford, PhD
Dr. Janet Stanford is a co-director of Core A (Leadership & Administration) of the PNW Prostate Cancer SPORE, a co-leader of Project 1 (Molecular Predictors of Prostate Cancer Progression and Mortality), and co-head of the Program in Prostate Cancer Research (PPCR). Dr. Stanford is a member of the Hutchinson Center and a research professor of epidemiology at the University of Washington’s School of Public Health. In the early 1990s, Stanford became one of the first Center researchers to focus on prostate cancer and today is recognized worldwide as an expert in the field. Her numerous studies and leadership of the program in prostate cancer research have illuminated many of the environmental, behavioral and genetic factors that can cause the disease. She also helps lead a nationwide research project of more than 2,000 people in more than 300 families exploring why prostate-cancer risk is higher in some families. Understanding the inherited genetic mutations for prostate cancer may provide new clues to help diagnose, treat, cure and even prevent it in future generations.
Dr. Stanford’s main research interests focus on hormonal, environmental, lifestyle and genetic factors that may alter cancer risk, cancer recurrence or progression, and cancer-specific mortality. The role of underlying genetic susceptibility based on rare, and high penetrance mutations as well as more common genetic variants of lower penetrance is a major focus of her research. As a cancer epidemiologist, Dr. Standford has been involved in the development, implementation, and analyses of research studies of the etiology and progression of several different types of cancer. However, her current concentration is on prostate cancer. The recent completion of two large population-based case-control studies of risk factors for prostate cancer has allowed Dr. Stanford and her research team to examine environmental/lifestyle exposures and genetic polymorphisms in candidate genes in relation to prostate cancer etiology and outcomes.

Ruth Etzioni, PhD
Ruth Etzioni is an affiliate professor of biostatistics and health services at the University of Washington and a member of the Hutchinson Center. Dr. Etzioni directs Core C (Biostatistics) of the PNW Prostate Cancer SPORE. Dr. Etzioni and her colleagues were among the first to formally evaluate the test’s ability to distinguish between true cancers and benign conditions. They have concluded that a variation on the PSA test that uses two types of PSA measurements could improve the test’s accuracy for men with borderline-normal total PSA levels, potentially leading to a significant drop in medical costs and complications for this group of men. Etzioni and colleagues have also determined that roughly one-third of older men diagnosed with prostate cancer through the PSA test are “overdiagnosed” with the disease, meaning patients are receiving unnecessary surgeries or other treatments even though the disease isn’t likely to threaten their health. Dr. Etzioni’s work currently focuses on the development and implementation of statistical methods for prostate cancer studies. In the past, she has worked on assessing the efficacy of 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). As leader of the biostatistics core for the Northwest Prostate Cancer 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. In addition to these projects, her current interests include modeling the development of resistance to androgen ablation therapy.

Elahe Mostaghel, MD, PhD
Elahe Mostaghel is co-leader of Project 5 (Exploiting Mechanisms of Response and Resistance to Next Generation Androgen Pathway Antagonists) of the PNW Prostate Cancer SPORE. She is an associate member in the Clinical Research Division at the Hutchinson Center and an associate professor in the Division of Medical Oncology at University of Washington, specializing in the care of men with advanced prostate and bladder cancer. Dr. Mostaghel completed her MD and PhD at Duke University, Internal Medicine residency training at the University of California at San Francisco, and Medical Oncology fellowship training at the UW/Hutchinson Center. Her research focuses on androgen and androgen receptor-related mechanisms of resistance that lead to prostate cancer progression, and how targeting these mechanisms can be exploited to optimize therapy. Current areas of research include pathways of intra-tumoral androgen steroidogenesis and metabolism, structural alterations in the androgen receptor, the activity of androgen transport proteins, and how alterations in these and other pathway may influence the sequencing of androgen and chemotherapy treatments. An important goal is to determine how patient and tumor-specific alterations in these proteins may be used to predict response to agents targeting these pathways.
Chris Ong, PhD
Chris Ong is co-leader of Project 3 (Targeting SEMA3C in Castration Resistant Prostate Cancer) of the PNW Prostate Cancer SPORE. He is an associate professor in the Department of Surgery with an associate appointment in the Department of Urologic Sciences at the University of British Columbia in Vancouver, BC. The primary focus of Dr. Ong’s research program is to understand the molecular mechanisms that govern the progression of prostate cancer from a state of androgen sensitivity to hormone independence with the hope of developing novel therapeutic strategies to prevent or delay the progression of prostate cancer to androgen independence. His primary focus has been on the PTEN tumor suppressor gene, which is among the most frequently mutated genes in cancer. One or both copies of PTEN is mutated in over 70% of primary prostate cancer and PTEN is completely inactivated in over 50% of advanced prostate cancer which correlates with a poor prognosis. Dr. Ong’s laboratory is currently studying how mutations of that gene confer protection of prostate cancer cells from cell death and resistance to chemotherapy as well as how loss of PTEN influences progression of prostate cancer cells to androgen independence. Implications from this research may lead to new therapeutic strategies designed to prevent or delay progression to androgen independence. Based on observations to date, Dr. Ong is testing the potential utility of several classes of small molecule drugs that act to down-modulate the PI3K survival pathway in the treatment of prostate cancer. These novel compounds have tremendous promise as lead compounds for development of therapeutics that target a primary defect associated with prostate cancer and other malignancies. Dr. Ong’s laboratory is also involved in the development of unique prostate tumor model systems which are used to characterize the function of a number of genes in normal and malignant prostate biology.
Stephen Plymate, MD
Steve Plymate is co-leader of Project 5 (Exploiting Mechanisms of Response and Resistance to Next Generation Androgen Pathway Antagonists) of the PNW Prostate Cancer SPORE. Areas of research in his program include:
- Control of prostate cancer growth and metastasis by inhibition of the type 1 IGF receptor with human monoclonal antibodies. Results in this area over the past year have shown that IGF-IR inhibition markedly enhances effects of castration by altering nuclear localization of the androgen receptor by changing AR phosphorylation sites. In collaboration with Dr. Bruce Montgomery, he has completed neo-adjuvant study of an IGF-IR monoclonal antibody combined with castration in men with high grade prostate cancer.
- The role of androgen receptor splicing as a mechanism of castration resistant prostate cancer. Dr. Plymate’s laboratory first described the ARv567es constitutively active splice variant in prostate cancer and its expression in human disease, the variant transcriptome, and splicing regulation of AR-V7 in response to castration. In addition, he has developed the first reported transgenic mouse in which AR-splice variants function as potential oncogenes.
- His laboratory is currently examining the interaction of ARv567es and PTEN loss in a transgenic mouse model.
- In collaboration with SPORE and DOD investigators, he is evaluating three new compounds that inhibit the amino-terminus of the AR and will thus inhibit all forms of the AR.
- Dr. Plymate has recently been awarded a DOD Transformative grant that includes two clinical trials targeting the AR as well as new laboratory methods for studying AR co-regulators and long-range chromatin interactions. He attends in the Prostate Cancer Clinic at the VA Puget Sound Healthcare System (VAPSHCS) and the transitional care unit at VAPSHCS.
