Abstract C004: Collecting evidence to drive research that addresses community cancer needs in Western Washington

Abstract

Abstract Background: The Fred Hutch/University of Washington Cancer Consortium (Consortium) is a National Cancer Institute-designated comprehensive cancer center located in the Seattle metro area. The Consortium comprises four partnering institutions (Fred Hutchinson Cancer Research Center, University of Washington, Seattle Children's Hospital, and Seattle Cancer Care Alliance [SCCA]) that together address the full spectrum of cancer research and interventions to reduce the burden of cancer among catchment area (CA) residents. The Consortium's CA is thirteen counties in western Washington (WA). In an effort to understand and document ongoing research conducted to address the cancer burden, risk factors, incidence, mortality, and inequities in the CA, we initiated a comprehensive needs assessment. Methods: We conducted a quantitative and qualitative needs assessment from September 2017 to June 2018. Quantitative assessment included secondary data analyses from multiple sources (Seattle-Puget Sound Surveillance, Epidemiology and End Results cancer registry, Behavioral Risk Factor Surveillance Survey data, and WA State Department of Health data). Qualitative assessment included semistructured interviews (n=32) conducted in person and over the telephone with key informants representing county health departments, clinic/health systems, SCCA network sites, and community-based organizations. Interviews included questions about barriers and facilitators to cancer screening, referrals, services, access to care, and cancer inequities. Results: The quantitative data analysis identified the top five cancer incidence sites in the CA as breast, prostate, lung, hematologic malignancies and colorectal; the top five mortality sites in the CA are lung, prostate, breast, hematologic malignancies and colorectal. Comparisons of incidence and mortality for the region revealed several inequities: 1) American Indians and Alaska Natives (AIAN) had the most numerous and severe inequities for incidence and mortality of the top cancers; 2) non-Hispanic Blacks had the most severe mortality for prostate cancer; and 3) outlying rural counties had higher incidence and mortality rates than urban areas. Through the qualitative data analysis, we identified seven major themes that influenced cancer prevention and control, including geography, social determinants of health, financial issues, issues around provider trust and communication, issues with agency partnerships/collaboration, and race/ethnicity. Qualitative interviews suggested opportunities for the Consortium to address barriers that underlie several major cancer inequities in the CA. Conclusion: The Consortium will use the needs assessment as a baseline measure to evaluate future research that addresses the cancer burden in the CA. The Consortium now has information to take an informed approach to engage key stakeholders to collaborate and holistically improve cancer research and outcomes for all CA residents.
