In 2019, nearly 2 million Americans will receive a cancer diagnosis and more than 600,000 will die of cancer. Cancer diagnoses and deaths are disproportionately high among people who live in rural counties, have a low socioeconomic status, and are members of underserved racial and ethnic groups.

The Cancer Prevention and Control Research Network (CPCRN), a collaborative national network of academic centers engaged in cancer research, has produced a supplemental issue of Preventive Medicine with 12 articles that examine stakeholder-engaged implementation science and population approaches to improve equity in cancer prevention and control. The research findings reported in the supplement investigate factors at the level of the patient, community, health care provider, health care system, and the wider socio-political context.

The supplemental issue represents a diversity of collaborative research products made possible by the research and scientific networking infrastructure enabled by CPCRN, which has been funded by the Centers for Disease Control and Prevention (CDC) and the National Cancer Institute (NCI), part of the National Institutes of Health (NIH), since 2002. CPCRN is a thematic network of the CDC’s Prevention Research Centers (PRCs) in which multiple centers collaborate on research related to the dissemination and implementation of evidence-based approaches to reduce the burden of cancer, especially in disproportionately affected populations. The University of North Carolina at Chapel Hill’s PRC, the Center for Health Promotion and Disease Prevention, hosts the network’s coordinating center.

For the 2014-2019 funding cycle, the CPCRN member centers included cancer investigators at Case Western Reserve University, Oregon Health & Science University, University of Iowa, University of Kentucky, University of North Carolina at Chapel Hill, University of Pennsylvania, University of South Carolina, and University of Washington.

“In this supplemental issue, CPCRN researchers take on two tasks that are essential to reducing disparities in cancer outcomes,” said Jennifer Leeman, a guest editor on the issue and principal investigator of the University of North Carolina CPCRN collaborating center. “First, they examine the multilevel factors that are contributing to cancer disparities, and, second, they identify strategies to speed the implementation of cancer screening interventions across the different levels where factors occur. Taken together, these articles report findings that will aid public health practitioners, policymakers, and others as they design and implement interventions to reduce the burden of cancer in underserved communities.”

The 12 articles included in the supplement illustrate the types of research that are possible within a network of geographically dispersed centers all thematically linked by a common cause — reducing cancer burden in diverse populations. The supplement begins with an article authored by CPCRN federal agency partners at the CDC and NCI that provides an overview of the network and its purpose and history. The supplement ends with an article authored by several network leaders about the potential impact of CPCRN on cancer control and prevention.

In four articles, researchers report findings from their cross-center research on factors that contribute to rural disparities in cancer outcomes and present a conceptual framework to guide future research to reduce rural disparities. In five articles, CPCRN researchers report findings related to interventions to increase colorectal cancer screening rates in underserved populations. In one of these articles, researchers report on a national survey of patient navigators and the barriers they encounter to enabling populations to receive timely colorectal, breast, and cervical cancer screening.

CPCRN facilitates and coordinates timely, high-impact research across the eight collaborating centers. Each center conducts research in its own community and region, as well as collaborates with other centers to conduct multi-state research studies in topic-oriented workgroups. The articles in this issue report on several workgroup initiatives and findings completed during the latest round of network funding between 2014 and 2019.

“Because it leverages geographically dispersed, interdisciplinary teams of investigators, CPCRN is in a unique position to study the individual, geographic, policy, and other multilevel factors that increase the risk for poor cancer outcomes,” said Stephanie Wheeler, the principal investigator for the CPCRN Coordinating Center. “The articles in this supplement highlight the diversity and strength of scientific ideas and leadership that a robust thematic research network like CPCRN can produce, where the network’s contribution to science and practice is clearly greater than the sum of its parts.”
