158 Background: Evidence that rural residents compared to urban residents are more likely to be diagnosed at later stages and have worse survival outcomes has prompted recent policy initiatives by ASCO to address the rural cancer care gap. However, rural residents are generally poorer, potentially confounding the cause of these disparities. This study examined the impact of rurality, travel time to oncologist (TTO), and neighborhood deprivation (ND) on stage of diagnosis and 3-year survival in a regional setting. Methods: Cancer registry records for patients in Western Washington were linked with claims from regional commercial insurers, Medicare, and Medicaid at time of diagnosis. The study included adult patients with solid tumors diagnosed between 2012-2014. Rurality was sourced from the Rural-Urban Commuting Area Codes (RUCAs): Metro, Metro with Commute, Micropolitan, Small Town/Rural. ND was measured by the census block Area Deprivation Index from 1 (least) to 10 (most) deprived; TTO from Google Maps (minutes). Multinomial logistic regression measured stage at diagnosis (local, regional, distant). Cox survival models were stratified by insurance type. We adjusted all models for age, gender, race, marital status, cancer type and grade, and hierarchical condition categories. Results: The table below lists the effect size of rurality, TTO, and ND on the outcomes where significant (p<0.05). Conclusions: In Washington State, neighborhood deprivation, not rurality, was largely associated with later stage at diagnosis and poorer survival. Regional stakeholders need to carefully examine the local sources of cancer care disparities to effectively target interventions.[Table: see text]
