Research Interests

Dr. De Roos' research interests and experience are primarily in occupational and environmental exposures to chemicals and radiation as risk factors for cancer, other chronic diseases, and intermediate biologic effects. She has conducted studies of lymphomas, leukemias, autoimmune diseases, childhood cancers, and adult brain tumors.

A focus of Dr. De Roos' research is in health effects of exposure to persistent organic pollutants (POPs). In a study of POPs in plasma as contributors to non-Hodgkin lymphoma (NHL) risk (Cancer Res, 2005), Dr. De Roos and colleagues found that certain moderate- and highly-chlorinated polychlorinated biphenyl (PCB) congeners were associated with two- to three-fold increased risk of NHL (comparing extreme quartiles). The dioxin-like furan compounds measured were also strongly associated with NHL incidence, with a significant trend across quartiles (p=0.006), and the toxic equivalency quotient (TEQ), a summed metric that weights congeners by their dioxin-like potency, was associated with 35% increased risk of NHL per 10 TEQ units. These results suggest that exposures to POPs, particularly dioxin-like POPs and certain non-dioxin-like PCBs, contribute to NHL risk. Dr. De Roos is currently investigating how PCB concentrations change during weight loss in a group of women participating in an exercise intervention trial, and how PCBs may affect immune function in these women.

Dr. De Roos is investigating environmental and occupational exposures in relation to lymphohematopoietic cancers in the Women's Health Initiative (WHI) study, including insecticide exposures and farming history. A possible mechanism by which environmental exposures may contribute to NHL risk is by affecting the immune system, either through immune suppression or B-cell activation and proliferation. In a case-control study nested within the WHI Observational Study, Dr. De Roos is investigating viral and immune markers in prediagnostic biologic samples as predictors of incident NHL. Markers of interest are antibodies to Epstein-Barr virus (EBV) antigens, circulating EBV DNA, and cytokines and other molecules involved in B-lymphocyte response, including IL6, IL10, TNFα, sCD23, sCD27, sCD30, sCD44, and CXCL13.

Several of Dr. De Roos' studies are exploring the use of geographic information systems and geographically-referenced environmental surveillance data to estimate individual-level exposures. One project focuses on environmental exposure to industrial pollution in relation to NHL risk, using data on industry locations, reported emissions, and census data. In another study, Dr. De Roos and investigators at the University of British Columbia are characterizing the possible role of air pollution in the incidence and exacerbation of rheumatoid arthritis in the Vancouver metropolitan region.
