Distribution of Genomic Testing Resources by Oncology Practice and Rurality: A Nationally Representative Study.

PURPOSE: Oncologists are increasingly using molecular profiling to inform personalized patient treatment decisions. Despite its promising utility, the integration of genomic testing into diverse clinical health care settings across geographic settings has been understudied. METHODS: We used data from the National Survey of Precision Medicine in Cancer Treatment, a nationally representative sample of practicing US oncologists, to assess the availability of six genomic testing resources, including on-site pathology, contracts with outside laboratories, on-site genetic counselors, internal policies or protocols for using genomic and biomarker testing, electronic medical record alerts, and genomic or molecular tumor boards. We used multivariate logistic regression models to examine differences in the availability of each genomic testing resource by practice type and rurality while adjusting for payer mix and patient volume. RESULTS: A larger proportion of multispecialty group and academic practices had genomic testing resources available compared with solo and nonacademic practices. Electronic medical record alerts were the least available resource, whereas contracts with outside laboratories were the most available resource. Compared with urban practices, there were significantly fewer practices located in rural areas that had on-site pathology, on-site genetic counselors, protocols for genomic tests, and molecular tumor boards. CONCLUSION: Genomic testing resources varied by practice type and geography among a nationally representative sample of practicing oncologists. This variation has important implications for the development of interventions and policies to support the more equitable delivery of precision oncology to patients with cancer.

Advancing Rural Cancer Control Research: National Cancer Institute Efforts to Identify Gaps and Opportunities.

Cancer mortality rates are approximately 8% higher in rural populations and mortality rates are falling more slowly in rural communities, resulting in widening rural-urban health disparities in the United States. The NCI has a long history of supporting health disparities research, including research to understand the health needs, strengths, and opportunities in rural communities. However, the portfolio analysis described in this article underscores the need to significantly accelerate rural cancer control research in partnership with state and local communities. This commentary outlines NCI's efforts over the last four years to address gaps in rural cancer control research and improve cancer prevention, control, and care delivery in rural populations. Future directions, challenges, and opportunities are also discussed.
