Many American Indian (AI) and Alaska native (AN) patients do not complete guideline-concordant cancer care for the 4 most common cancers. Our aim was to better understand AI/AN attitudes toward radiation therapy (RT). Patients eligible for this survey study were AI/AN patients with cancer at the Phoenix Indian Medical Center who either received previous RT or were recommended to receive RT. An 18-item questionnaire was administered to each of the 50 participants from October 1, 2018, through February 15, 2019. Willingness to travel for RT was compared to respondent characteristics, concerns regarding RT, and obstacles to obtain RT. Duration of RT was important to 78% of patients: 24% would consider traveling 25 miles or more for a standard course, and 48% would travel that distance for a shorter course ( P < .001). The top-ranked barriers to RT were transportation, cost of treatment, and insurance compatibility. The top-ranked concerns about RT were adverse effects, cost of treatment, and fear of RT. Concerns about adverse effects were associated with the radiation team’s inability to explain the treatment ( P = .05). Transportation concerns were significantly associated with accessibility ( P = .02), communication with the RT team ( P = .02), and fear of RT ( P = .04). AI/AN patients are concerned about the adverse effects of RT and the logistics of treatment, particularly costs, transportation, and insurance compatibility. Use of culturally specific education and hypofractionation regimens may increase acceptance of RT for AI/AN patients with cancer, and this hypothesis will be tested in a future educational intervention-based study.

79 Background: Novel mechanisms are needed to provide high quality oncologic clinical care and clinical trial access to underserved and minority populations (UMP). UMP are underrepresented in cancer clinical trials, thus limiting the generalizability of the research. As a National Cancer Institute-Comprehensive Cancer Center, Mayo Clinic has the responsibility to ensure that its cancer care reaches a diverse patient population. Mayo Clinic in Arizona developed a clinical oncology practice in collaboration with the US Indian Health Service at Phoenix Indian Medical Center (PIMC), in part to address these needs. The relationship between Mayo and PIMC is invaluable and serves a crucial need in the community. The Mayo consultants serve as staff physicians in the “Oncology Center of Excellence” at PIMC and see 100 – 200 tribal members annually with new diagnoses of cancer or blood disorders. Being onsite at PIMC allows Mayo consultants to integrate seamlessly into the wider PIMC practice. Methods: Descriptive demographic data from the MCA-PIMC clinical practice were obtained from the PIMC practice database 2008 - 2017. Enrollment of MCA-PIMC patients into MCA cancer clinical trials were prospectively enumerated. Results: Between the time period of 2008-2017, 356 breast cancer patients and 259 colorectal cancer patients were seen by Mayo Clinic oncologists and the PIMC nurse practitioner. During the period of 2016-2017, there were 13 clinical trial referrals from PIMC with 8 of those patients being enrolled in Mayo cancer clinical trials. Conclusions: High quality oncologic clinical care can be provided via unique collaborations between academic oncology program and UMP-focused care provider. This mechanism allows access to cancer clinical trial opportunities for UMP. Prior to the established partnership, there were no Native American patients referred to clinical trials from PIMC, showing the critical pathway that has been forged. Importantly, this is the only known program of its kind in the country. By imbedding the cancer provider in the community, we are able to build trust with the underserved community and create a pathway to a quality care and clinical research.

In recent years, the emerging electronic cigarette (e-cigarette) marketplace has shown great development prospects all over the world. Reddit, one of the most popular forums in the world, has a very large user group and thus great influence. This study aims to gain a systematic understanding of e-cigarette flavors based on data collected from Reddit. Flavor popularity, mixing, characteristics, trends, and brands are analyzed. Fruit flavors were mentioned the most (n = 15,720) among all the posts and were among the most popular flavors (n = 2902) used in mixed blends. Strawberry and vanilla flavors were the most popular for e-juice mixing. The number of posts discussing e-cigarette flavors has increased sharply since 2014. Mt. Baker Vapor and Hangen were the most popular brands discussed among users. Information posted on Reddit about e-cigarette flavors reflected consumers’ interest in a variety of flavors. Our findings suggest that Reddit could be used for data mining and analysis of e-cigarette-related content. Understanding how e-cigarette consumers’ view and utilize flavors within their vaping experience and how producers and marketers use social media to promote flavors and sell products could provide valuable information for regulatory decision-makers.
