Mapping the European cancer prevention research landscape: A case for more prevention research funding

Despite the strong evidence of prevention as a prime defence against the disease, the majority of cancer research investment continues to be made in basic science and clinical translational research. Little quantitative data is available to guide decisions on the choice of research priorities or the allocation of research resources. The primary aim of the mapping of the European cancer prevention research landscape presented in this paper is to provide the evidence-base to inform future investments in cancer research. Using bibliometric data to identify funders that are active in prevention research in Europe and in the world, we have identified that 14% of cancer research papers had a focus on prevention research and those were funded by 16% of all the European cancer research funders. An important finding of our study is the lack of research on primary prevention with primary prevention funders accounting for 25% of European cancer prevention funders, meaning that less than 4% of all European cancer research funders identified show an interest in primary prevention. An additional analysis revealed that 7% of European cancer prevention research papers are categorised as implementation projects, meaning that only 1% of all cancer research publications are implementation research in cancer prevention. This paper highlights that the narrow focus on biology and treatment in Europe needs to be widened to include such areas as primary prevention and secondary prevention and a larger concentration on implementation research. These data can help support a more policy-focused cancer research agenda for individual European governments and charitable and philanthropic organisations and stimulate joining efforts across Europe to create a more systematic and structured approach to cancer prevention.

Advancing the science of integrating multiple interventions by blending and bundling.

Cancer prevention and control research has produced a variety of effective interventions over the years, though most are single disease focused. To meet the Cancer Moonshot goal to reduce the cancer death rate by 50% by 2047, it may be necessary to overcome the limitations of siloed interventions that do not meet people's multiple needs and limitations in system capacity to deliver the increasing number of interventions in parallel. In this article, we propose integrating multiple evidence-based interventions as a potential solution. We define 2 types of integrated interventions, blended and bundled, and provide examples to illustrate each. We then offer a schematic and outline considerations for how to assemble blended or bundled interventions including looking at the intervention need or opportunity along the cancer continuum as well as co-occurring behaviors or motivations. We also discuss delivery workflow integration considerations including social-ecological level(s), context or setting, implementer, and intended beneficiary. Finally, in assembling integrated interventions, we encourage consideration of practice-based expertise and community and/or patient input. After assembly, we share thoughts related to implementation and evaluation of blended or bundled interventions. To conclude the article, we present multiple research opportunities in this space. With swift progress on these research directions, cancer prevention and control interventionists and implementation scientists can contribute to achieving the promise of the reignited Cancer Moonshot.

Toward a more comprehensive understanding of organizational influences on implementation: the organization theory for implementation science framework.

Implementation is influenced by factors beyond individual clinical settings. Nevertheless, implementation research often focuses on factors related to individual providers and practices, potentially due to limitations of available frameworks. Extant frameworks do not adequately capture the myriad organizational influences on implementation. Organization theories capture diverse organizational influences but remain underused in implementation science. To advance their use among implementation scientists, we distilled 70 constructs from nine organization theories identified in our previous work into theoretical domains in the Organization Theory for Implementation Science (OTIS) framework. The process of distilling organization theory constructs into domains involved concept mapping and iterative consensus-building. First, we recruited organization and implementation scientists to participate in an online concept mapping exercise in which they sorted organization theory constructs into domains representing similar theoretical concepts. Multidimensional scaling and hierarchical cluster analyses were used to produce visual representations (clusters) of the relationships among constructs in concept maps. Second, to interpret concept maps, we engaged members of the Cancer Prevention and Control Research Network (CPCRN) OTIS workgroup in consensus-building discussions. Twenty-four experts participated in concept mapping. Based on resulting construct groupings' coherence, OTIS workgroup members selected the 10-cluster solution (from options of 7-13 clusters) and then reorganized clusters in consensus-building discussions to increase coherence. This process yielded six final OTIS domains: organizational characteristics (e.g., size; age); governance and operations (e.g., organizational and social subsystems); tasks and processes (e.g., technology cycles; excess capacity); knowledge and learning (e.g., tacit knowledge; sense making); characteristics of a population of organizations (e.g., isomorphism; selection pressure); and interorganizational relationships (e.g., dominance; interdependence). Organizational influences on implementation are poorly understood, in part due to the limitations of extant frameworks. To improve understanding of organizational influences on implementation, we distilled 70 constructs from nine organization theories into six domains. Applications of the OTIS framework will enhance understanding of organizational influences on implementation, promote theory-driven strategies for organizational change, improve understanding of mechanisms underlying relationships between OTIS constructs and implementation, and allow for framework refinement. Next steps include testing the OTIS framework in implementation research and adapting it for use among policymakers and practitioners.

The special sauce of the Cancer Prevention and Control Research Network: 20 years of lessons learned in developing the evidence base, building community capacity, and translating research into practice

PurposeThe Cancer Prevention and Control Research Network (CPCRN) is a national network focused on accelerating the translation of cancer prevention and control research evidence into practice through collaborative, multicenter projects in partnership with diverse communities. From 2003 to 2022, the CPCRN included 613 members.MethodsWe: (1) characterize the extent and nature of collaborations through a bibliometric analysis of 20 years of Network publications; and (2) describe key features and functions of the CPCRN as related to organizational structure, productivity, impact, and focus on health equity, partnership development, and capacity building through analysis of 22 in-depth interviews and review of Network documentation.ResultsSearching Scopus for multicenter publications among the CPCRN members from their time of Network engagement yielded 1,074 collaborative publications involving two or more members. Both the overall number and content breadth of multicenter publications increased over time as the Network matured. Since 2004, members submitted 123 multicenter grant applications, of which 72 were funded (59%), totaling more than $77 million secured. Thematic analysis of interviews revealed that the CPCRN’s success—in terms of publication and grant productivity, as well as the breadth and depth of partnerships, subject matter expertise, and content area foci—is attributable to: (1) its people–the inclusion of members representing diverse content-area interests, multidisciplinary perspectives, and geographic contexts; (2) dedicated centralized structures and processes to enable and evaluate collaboration; and (3) focused attention to strategically adapting to change.ConclusionCPCRN’s history highlights organizational, strategic, and practical lessons learned over two decades to optimize Network collaboration for enhanced collective impact in cancer prevention and control. These insights may be useful to others seeking to leverage collaborative networks to address public health problems.

Supporting implementation science and health equity in cancer prevention and control through research networks

The Cancer Prevention and Control Research Network (CPCRN) is a national network of academic, public health, and community organizational partners across multiple geographic sites who collaborate to reduce the cancer burden in diverse communities. Given key recommendations that suggest the need for cross-disciplinary collaboration in cancer prevention and control, we sought to explore the historical and contemporary evolution of health equity and disparities research as an area of focus within the CPCRN over time. We conducted 22 in-depth interviews with former and current leaders, co-investigators, and other members of the network. Several key themes emerged from data that were analyzed and interpreted using a constructivist, reflexive, thematic analysis approach. Nearly all participants reported a strong focus on studying health disparities since the inception of the CPCRN, which offered the network a distinct advantage in recent years for incorporating an intentional focus on health equity. Recent law enforcement injustices and the inequities observed during the COVID-19 pandemic have further invigorated network activities around health equity, such as development of a health equity-focused workgroup toolkit, among other cross-center activities. Several participants noted that, in terms of deep, meaningful, and impactful health equity-oriented research, there are still great strides for the network to make, while also acknowledging CPCRN as well-aligned with the national dialogue led by federal agency partners around health equity. Finally, several future directions were mentioned by the participants, including a focus on supporting a diverse workforce and engaging organizational partners and community members in equity-focused research. Findings from these interviews provide direction for the network in advancing the science in cancer prevention and control, with a strengthened focus on health equity.

Twenty years of collaborative research to enhance community practice for cancer prevention and control.

The Cancer Prevention and Control Research Network (CPCRN) was established in 2002 to conduct applied research and undertake related activities to translate evidence into practice, with a special focus on the unmet needs of populations at higher risk of getting cancer and dying from it. A network of academic, public health and community partners, CPCRN is a thematic research network of the Prevention Research Centers Program at the Centers for Disease Control and Prevention (CDC). The National Cancer Institute's Division of Cancer Control and Population Sciences (DCCPS) has been a consistent collaborator. The CPCRN has fostered research on geographically dispersed populations through cross-institution partnerships across the network. Since its inception, the CPCRN has applied rigorous scientific methods to fill knowledge gaps in the application and implementation of evidence-based interventions, and it has developed a generation of leading investigators in the dissemination and implementation of effective public health practices. This article reflects on how CPCRN addressed national priorities, contributed to CDC's programs, emphasized health equity and impacted science over the past twenty years and potential future directions.

RORγt-Raftlin1 complex regulates the pathogenicity of Th17 cells and intestinal inflammation.

Abstract Th17 cells that produce IL-17 are pathogenic in many human diseases, including inflammatory bowel disease (IBD), but are, paradoxically, essential for maintaining the integrity of the intestinal barrier in a non-inflammatory state. However, the intracellular mechanisms that regulate distinct transcriptional profiles and functional diversity of Th17 cells remain unclear. We have found that Raftlin1, a lipid raft protein, is specifically upregulated in and forms a complex with RORγt via its conserved LLNSL motif in pathogenic Th17 cells. Disruption of the RORγt-Raftlin1 complex in Raftlin1 ΔLLNSLknock-in mice resulted in attenuated pathogenic Th17 cells elicited by Citrobacter rodentium; however, there was no effect on nonpathogenic Th17 cells induced by commensal segmented filamentous bacteria (SFB). Mechanistically, we found that Raftlin1 recruits distinct phospholipids to RORγt and promotes the pathogenicity of Th17 cells. Thus, we have identified a fundamental mechanism that drives the pathogenic function of Th17 cells, which could provide a platform for new therapeutic strategies to dampen Th17-mediated inflammatory diseases. This work was supported by funds from the National Institutes of Health (R01-DK115668, R01-AI155786) and Cancer Prevention Research Institute of Texas (RP190527) and a stimulus grant from the Harold C.

Pak2-mediated phosphorylation promotes RORγt ubiquitination and inhibits colonic inflammation

Abstract Dysregulated Interleukin (IL)-17 expression and its downstream signaling is strongly linked to inflammatory bowel diseases (IBD). However, the molecular mechanisms by which the function of RORγt, the transcription factor of IL-17, is regulated remains elusive, which is absolutely necessary to develop advanced strategies to inhibit IL-17-mediated inflammation. By mass spectrometry-based approach, we have identified that Pak2, a Ser/Thr kinase, directly associates with RORγt. Pak2 recognizes a conserved KRLS motif within RORγt and phosphorylated the Serine (S) 316 within this motif. Genetic deletion of Pak2 in Th17 cells resulted in reduced RORγt phosphorylation, increased IL-17 expression and severe colitis upon adoptive transfer to Rag1 −/−mice. Similarly, reconstitution of RORγt-S316A mutant in Rorc −/−Th17 cells resulted in enhanced IL-17 expression and colitis severity. Mechanistically, we demonstrate that Pak2-mediated phosphorylation causes a conformational change resulting in exposure of the ubiquitin ligase Itch interacting PPLY motif and degradation of RORγt. Thus, we have uncovered a novel mechanism by which the activity of RORγt is regulated that can be exploited therapeutically. This work was supported by funds from the National Institutes of Health (R01-DK115668 and R01-AI155786) and Cancer Prevention Research Institute of Texas (RP160577 and RP190527), a translational pilot project grant from the Harold C. Simmons Comprehensive Cancer Center, UT Southwestern Medical Center (23001045) to K.V., and R01-DK117001 to K.V. and A.L.T.

Mixed methods evaluation of the inaugural year of the Cancer Prevention and Control Research Network’s (CPCRN) scholars program

PurposeA diverse workforce trained in dissemination & implementation (D&I) science is critical for improving cancer outcomes and reducing cancer-related health disparities. This study aims to describe and evaluate impact of the Cancer Prevention and Control Research Network (CPCRN) Scholars Program in preparing scholars for collaborative careers in cancer control and implementation research and practice, and offers evaluation-driven recommendations for program improvements.MethodsThe CPCRN Scholars Workgroup conducted a sequential, mixed methods evaluation. We collected baseline and follow-up surveys and invited all 20 scholars and ten mentors to participate in an exit interview. We assessed the experience with the Scholar’s program, ratings of D&I competences, progress on their project, feedback about the curriculum, and understanding of implementation science.ResultsOver 86% partially or fully completed their project within 9 months; 78% of scholars engaged with a CPCRN workgroup. Scholars rated the following program components as valuable: the Putting Public Health Evidence in Action (PPHEIA) training (88.9%), D&I training modules (83.3%), and webinars (kickoff webinar-88.9% and selecting theories/models-88.9%). There was an increase in D&I competencies from baseline to posttest, with the greatest in community engagement topics. About 78% reported that they were satisfied with format of the activities and increased confidence in ability to discuss D&I concepts. From the qualitative interviews, the benefit of the program was becoming more knowledgeable about D&I research and networking.ConclusionThe inaugural year of the program yielded positive results, particularly related to increasing knowledge about D&I science and cancer control. This program builds the capacity of students, researchers and practitioners in D&I science.

Role of Antioxidant Vitamins and Other Micronutrients on Regulations of Specific Genes and Signaling Pathways in the Prevention and Treatment of Cancer

Cancer is an escalating global issue, with 19.3 million new cases and 9.9 million deaths in 2020. Therefore, effective approaches to prevent cancer are urgently required. Diet plays a significant role in determining cancer risk. Nutrients and food bioactives influence specific signaling pathways in the body. Recently, there have been significant advances in cancer prevention research through nutrigenomics or with the effects of dietary components on the genome. Google Scholar, PubMed, and Scopus databases were used to search for peer-reviewed articles between 2017 and 2023. Criteria used were vitamins, minerals, tumors, cancer, genes, inflammation, signaling pathways, and nutrigenomics. Among the total of 1857 articles available, the highest relevant 90 articles that specifically discussed signaling pathways and genes on cancer cell lines and human cancer patients were selected and reviewed. Food sources are rich in antioxidant micronutrients, which are effective in activating or regulating signaling pathways involved in pathogenesis and cancer therapy by activating enzymes such as mitogen-activated protein kinase (MAPK), protein kinase C (PKC), and phosphatidylinositol 3-kinase (PI3K). The micronutrients are involved in the regulation of β-catenin (WNT/β-catenin) including mutations in Kras and epidermal growth factor receptor (EGFR) alongside inhibition of the NF-kB pathway. The most common mechanism of cancer prevention by these micronutrients is their antioxidative, anti-inflammation, and anti-apoptosis effects. This review discusses how nutrigenomics is essential and beneficial for developing cancer prevention and treatment approaches.

Pancreatic Cancer Disparities among Gender, Race, and Ethnicity: The PRECEDE Consortium Outcomes and Impact.

The Pancreatic Cancer Early Detection (PRECEDE) Consortium was launched internationally to assess the surveillance of high-risk individuals (HRI) of pancreatic cancer, focusing on genetic risk factors. In the early recruitment period of 3 years from May 2020 to March 2022, the PRECEDE gathered analysis-eligible data on 1,113 HRIs. In this issue of Cancer Prevention Research, Katona and colleagues reported current portrait of demographics of the participants, with significant disparities in gender, race and ethnicity. Now the PRECEDE Consortium aims at correcting these disparities in the next 3 years and double the percentage of underrepresented groups to more closely represent the demographics of patients. See related article by Katona et al., p. 343.

Identifying research practices toward achieving health equity principles within the Cancer Prevention and Control Research Network

PurposeAlthough there is national recognition for health equity-oriented research, there is limited guidance for researchers to engage partnerships that promote health equity in cancer research. The Cancer Prevention and Control Research Network’s (CPCRN) Health Equity Work Group developed a toolkit to guide researchers in equitable collaborations.MethodsThe CPCRN’s Health Equity Work Group collectively outlined health and racial equity principles guiding research collaborations with partners that include communities, community-based organizations, implementing partners in the clinical setting including providers and health care organizations, and policy makers. Using a network-wide survey to crowdsource information around ongoing practices, we leveraged and integrated the network’s experience and collaborations.ResultsData from the survey formed the preliminary basis for the toolkit, with a focus on sharing fiscal resources with partners, training and capacity building, collaborative decision-making, community-driven research agenda setting, and sustainability. The final toolkit provides reflection considerations for researchers and collated exemplary resources, supported by the contemporary research.ConclusionsThe toolkit provides a guide to researchers at all experience levels wanting to engage in equitable research collaborations. Future efforts are underway to evaluate whether and how researchers within and outside CPCRN are able to incorporate these principles in research collaborations.

Principles to operationalize equity in cancer research and health outcomes: lessons learned from the cancer prevention and control research network

Reflecting their commitment to advancing health equity, the Cancer Prevention and Control Research Network (CPCRN) established a Health Equity Workgroup to identify and distill guiding principles rooted in health equity, community-engaged participatory research (CBPR), social determinants of health, and racial equity frameworks to guide its collective work. The Health Equity Workgroup utilized a multi-phase, participatory consensus-building approach to: (1) identify recurrent themes in health and racial equity frameworks; (2) capture perspectives on and experiences with health equity research among CPCRN members through an online survey; (3) engage in activities to discuss and refine the guiding principles; and (4) collect case examples of operationalizing equity principles in cancer research. Representatives from all CPCRN centers endorsed nine core principles to guide the Network’s strategic plan: (1) Engage in power-sharing and capacity building with partners; (2) Address community priorities through community engagement and co-creation of research; (3) Explore and address the systems and structural root causes of cancer disparities; (4) Build a system of accountability between research and community partners; (5) Establish transparent relationships with community partners; (6) Prioritize the sustainability of research benefits for community partners; (7) Center racial equity in cancer prevention and control research; (8) Engage in equitable data collection, analysis, interpretation, and dissemination practices; and (9) Integrate knowledge translation, implementation, and dissemination into research plans. Dissemination products, such as toolkits and technical assistance workshops, reflecting these principles will foster knowledge transfer to intentionally integrate health and racial equity principles in cancer prevention and control research.

How COVID-19 exposed pre-existing roadblocks for cancer control in Africa: strategies, lessons and recommendations from the 2019-2020 Africa Cancer Research and Control ECHO.

The COVID-19 related mitigation measures adversely affected various cancer control activities in Africa, with cancer prevention and screening activities amongst the most significantly impacted. When the COVID-19 pandemic struck, the Africa Cancer Research and Control ECHO utilised their virtual platform to share experiences and knowledge of how to continue cancer service delivery during the pandemic. This analysis describes the evolved strategies, dilemmas, and recommendations to strengthen the health systems for cancer control in Africa. Eleven 1-hour-long sessions about the then newly emerging coronavirus infection and its impact on cancer control in Africa were held from April 2020 to August 2020, using Zoom®. An average of 39 participants attended the sessions including scientists, clinicians, policymakers and global partners. Sessions were analysed thematically. Most strategies to maintain cancer services during the COVID-19 pandemic centred around cancer treatment, with few strategies on maintaining cancer prevention services, early detection, palliative care and research services. The most mentioned challenge during the pandemic was fear of exposure to COVID-19 infection at the health facility during diagnosis, treatment or follow-up for cancer care. Other challenges were disruptions to service delivery, inaccessibility of cancer treatment, disruption of research activities and a lack of psychosocial support for COVID-19 related fear/anxiety. Significantly, this analysis shows that the COVID-19 related mitigation measures exacerbated existing predicaments in Africa, such as inadequate attention to cancer prevention strategies, psychosocial and palliative services and cancer research. The Africa Cancer ECHO recommends African countries to leverage the infrastructure developed in response to COVID-19 pandemic to strengthen the health system along the entire cancer control continuum. This calls for urgent action to develop and implement evidence-based frameworks and comprehensive National Cancer Control Plans that will withstand any future disruptions.

Abstract B120: Identifying cancer disparities research gaps in NCORP: A pilot portfolio analysis

Abstract Background/Purpose: Clinical trials offer an underutilized platform to address health disparities. Most disparities-related work in clinical trials has focused on improving patient diversity, rather than on the research questions to reduce disparities. Within the NCI Community Oncology Research Program (NCORP), a large community-based clinical trials network, cancer disparities research incorporates the needs of diverse populations across its scientific portfolio of cancer control, symptom science, prevention, and care delivery studies. The objective of this portfolio analysis was to pilot a process to identify disparities-focused studies and related research gaps. Methods: We identified NCORP studies approved between August 2014-April 2021 with a focus on NIH health disparity and NCORP populations of interest (e.g., racial/ethnic minorities, rural residents, older adults, adolescent/young adults). After screening study titles and aims, studies were included if they focused exclusively on cancer disparities (primary aim) or had a disparities-related aim in studies with a broader focus (secondary aim). Coders abstracted study protocols across NCORP research areas, study-, cancer- and disparities-related characteristics. Coding disagreements were discussed until agreement. Descriptive statistics are reported. Results: The search identified 101 NCORP approved studies, of which 31% (n=31) were deemed disparities-focused. Most disparities-focused studies had primary disparities aims (n=26); fewer had secondary disparities aims (n=5). Sixty-five percent focused on populations underrepresented in clinical trials (9 older adults, 8 AYAs, and 3 other underserved), and 35% focused on health disparity populations (7 racial/ethnic minorities, 2 rural, and 2 socioeconomically disadvantaged). Most studies were available to English-speaking patients only (n=17), with Spanish the most common language accommodation (n=9). By NCORP scientific scope, 20 studies assessed patients’ quality of life, cancer-related or treatment-related symptoms; fewer addressed care delivery (n=8), prevention (n=1), or other topics (n=2). The most common outcome was adverse events or toxicity (n=6) and studies mostly included patients in active (n=19) versus post-treatment (n=10). Study designs were observational (n=15) or interventional (n=16) and examined individual (n=14), interpersonal (n=15) or multiple domains of influence (n=2). Conclusion: Through this pilot we defined a process to identify and describe NCORP disparities focused research and assessed related gaps. Over 30% of studies in the pilot had a primary disparities aim and focused on several populations of interest. Preliminary recommendations based on this pilot include strategies to increase secondary disparities approaches, disparities focused cancer prevention and care delivery research, studies examining multiple domains of influence, and expansion of language availability. NCORP’s strong infrastructure will build on this work to enhance the portfolio of disparities research in the community setting. Citation Format: Brenda A.

Aspirin for the primary prevention of breast cancer: an unforeseen advantage

Aspirin for the primary prevention of breast cancer: an unforeseen advantage

Abstract P034: Prevent Cancer-Greenville: identifying and influencing cancer risk

Abstract Purpose: Prevent Cancer - Greenville started in 2018 and provides study participants the opportunity to have their risk of developing cancer stratified into a personalized plan of screening and behavior modification as well as contribute to longitudinal cancer prevention research. Prevent Cancer - Greenville’s dual objectives include a participant educational focus based on individual risks as well as a long-term research objective of correlation of lifestyle and environmental influences on an individual’s molecular constitution and for those affected, the development of a cancer. Methods: Volunteer participants are accrued through open enrollment which is promoted through Prisma News, printed and online news articles, community events and a listing on the National Institute of Health clinicaltrials.gov website. Participants must be at least 18 years of age and must speak English to enroll. Enrollees participate in a yearly risk assessment, including diet, exercise, body composition using bioimpedance spectroscopy, and individual risk factors, with the data banked in a longitudinal manner. At each yearly visit, blood, urine, and buccal swab specimens are collected and stored along with participant’s lifestyle habits, body composition, and medical history as discrete data points. The potential to store thousands of participants’ specimens yearly for a decade or more creates an opportunity to retrospectively identify the likely multiple and sequential molecular events leading to the development of cancer. In short, patients eventually developing a malignancy will have a biological repository of DNA, RNA, and proteins that can potentially be deciphered as “steppingstones” leading to their illness. These molecular signatures will open the prospect of predicting cancer event pathways before clinical cancer develops, helping to correlate the epigenetic hallmarks of cancer development (nutrition, exercise, body fat content, microbiome). Results: Our team analyzed the current data collection for the 848 total participants accrued. The participants are 77.2% female and 22.8% male. Race is made up of 91.6% Caucasian, 6.3% African American, 1.3% Asian, and 0.7% Other. Ethnicity includes 2.6% Hispanic or Latino and 97.4% Non-Hispanic or Latino. A total of 11 participants have developed cancer since enrollment in the study. A total of 1600 buccal aliquots, 4,496 blood aliquots, and 888 urine aliquots are currently stored in the biorepository. Germline testing provided by a genetic counselor outside of the study identified 107 participants with pathogenic gene variants. Conclusion: The sequential annual visits will allow future molecular mapping and support strategies for early identification of malignancy and prevention of clinical disease through targeted interventions. To date, improving diversity has been challenging despite continued efforts. Citation Format: Larry Gluck, Armand DeSollar, Matthew Hudson, LeAnn Perkins, Julia Yates, Susan Webb, Gina Franco.

METHODOLOGICAL APPROACHES TO GERONTOLOGICAL CANCER RESEARCH

Abstract The wide range of gerontological cancer research necessitates a variety of methodological approaches. In our symposium, we bring together researchers who represent varied approaches to studying multiple cancer types—with a focus on demonstrating how to apply different methods. First, Ye, will discuss the use of a unique cross-sequential design to facilitate comparison between health change in long-term older cancer survivors and demographically-matched older adults with no history of cancer. Zanwar, will present disparities in cancer screening using secondary nationally representative complex survey data, provide examples of survey data that can be utilized in aging and cancer prevention and control research, and present challenges and opportunities for using survey data. Von Ah, will discuss research methods pertaining to a series of non-pharmacological clinical trials and offer insight to reducing barriers and improving acceptability to technology-based intervention programs in older breast cancer survivors. Next, Castaneda will present quantitative (i.e., group trajectory modeling, conditional Poisson regression) and qualitative approaches to understand the role of monoclonal gammopathy of undetermined significance in healthcare utilization and progression to multiple myeloma. Last, Halpin will discuss the use of naturally occurring data such as participant observation and audio recordings to evaluate education for patients with multiple myeloma preparing for autologous stem cell transplant. Understanding how a variety of methodological approaches are applied to gerontological cancer research will help facilitate a broader understanding of the tools available for these studies.
