Breast Cancer Prevention Practices and Knowledge in Italian and Chinese Women in Italy: Clinical Checkups, Free NHS Screening Adherence, and Breast Self-Examination (BSE).

Breast cancer remains a significant global concern, underscoring the critical need for early detection and prevention strategies. Primary and secondary preventive measures, such as routine screenings and behaviors like breast self-examination (BSE), play a crucial role in facilitating early diagnosis. While the National Health System (NHS) in Italy offers free regular screenings for women aged 50-69, there is a lack of clarity regarding the participation of both Italian and Chinese women residing in Italy in these screening programs. This study aims to bridge this knowledge gap by thoroughly assessing the involvement in regular clinical check-ups and the types of screening employed, the adherence to free screenings offered by the NHS, and the practice of BSE among women aged 50-69 of these two groups. Furthermore, it investigates their knowledge and perceptions regarding breast cancer and BSE. Results reveal disparities in breast cancer control practice between Italian and Chinese women in Italy: the former demonstrates higher adherence to clinical checkups (53% vs. 3%, p < 0.001), while both groups show low participation in free NHS screenings (70% vs. 4%, p < 0.001). Additionally, Chinese women reported significantly lower frequency of mammography (96% vs. 33%, p < 0.001) and ultrasound (69% vs. 16%, p < 0.001). The frequency of BSE also differed substantially, with 47% of Chinese women never performing BSE compared to 12% of Italian women (p < 0.001). This comprehensive exploration provides valuable insights, attitudes, and knowledge into the disparities and potential areas for improvement in breast cancer prevention, thus contributing to the overall well-being of these communities. The findings highlight the necessity for educational initiatives aimed at improving awareness and participation in screenings, particularly among the Chinese population. These initiatives could have profound implications for patient education by equipping women with the knowledge and skills necessary to engage in proactive health behaviors.

Abstract 821: Uptake of cervical cancer screening services by women living with HIV in Kajiado County Kenya

Abstract Background: This project is an African Caribbean Cancer Consortium (AC3) facilitated study: Women living with HIV (WLHIV) are more susceptible to cancer due to their immune-compromised status. The Kenya Ministry of Health recommends that women diagnosed with HIV should be screened for cervical cancer annually by either visual inspection with acetic acid (VIA) or visual inspection with Lugol’s iodine (VILI), cytology and testing for HPV once every two years. Objective: We determined the uptake of cervical cancer screening and HPV testing by women living with HIV (WLHIV) in Kajiado County in 2022. Methodology: The electronic health information system was used to abstract data for WLHIV in Kajiado county. Kajiado county has 57 antiretroviral (ART) facilities. However, our analysis accessed data from 38 facilities whose data is captured in the health information system. Authorized health care workers from the county were requested to abstract redacted data from the health information system. No personal identifiers were collected from the system as a means of protecting the privacy of individuals and abiding with the Kenya’s data protection law. Authorization to access the county was obtained from the county’s department of health while ethical approval was obtained from Mount Kenya University’s Institutional Scientific and Ethics Review Committee. Results: A total of 16,827 people living with HIV were enrolled for care at the 38 ART selected sites in 2022. Out on the total population that was enrolled for care, 11,785 (70%) were women with an age range of 15 to 49 years. A total of 3342 WLHIV, representing 28.36% of the target population, were screened by using visual inspection with acetic acid (VIA). Data for other methods of screening and HPV testing was not available in the health information systems. Of those screened, 3240 (97%) tested negative, 78 (2.3%) had positive results while 24 (0.7%) had suspicious lesions. Conclusion: Our analysis shows low uptake of cervical cancer screening services with only 28.36% of the targeted women being screened in 2022. The only available testing method (VIA) is less robust as compared to cytology and HPV testing. We also found a gap in reporting of HPV testing in the county. We thus recommend implementation science research examining the systemic barriers to HPV testing and reporting to better inform best practice HPV-related cancer prevention and control policy and practice to reduce cancer-related morbidity and mortality among WLHIV.

Contributions to Research and Practice Made by the National Cancer Institute’s Health Communication and Informatics Research Branch

ABSTRACT The Health Communication and Informatics Research Branch at the U.S. National Cancer Institute was founded in 1999 in response to increasing evidence demonstrating a link between effective health communication and improved cancer-related outcomes and in recognition of the rapid and dramatic technological changes that were transforming health communication at the turn of the 21st century. For the past 25 years, the Health Communication and Informatics Research Branch has been conducting and supporting research at the forefront of emerging cancer communication trends and technologies, making numerous contributions to health communication science, public health, and cancer control practice. In this essay, we provide a brief history of the branch and the context that led to its establishment, discuss contributions made by the branch to health communication research and practice through key projects and initiatives, and conclude by highlighting health communication and informatics research priorities that offer opportunities for significant impact going forward in light of the challenges posed by the current communication environment.

Growth and development of oncology nursing in Asia.

Oncology nursing is increasingly recognized around the world as being vitally important for an effective cancer control system. Granted, there is variation between and among countries regarding the strength and nature of that recognition, but oncology nursing is clearly seen as a specialty practice and as a priority for development in cancer control plans, especially for high resource countries. Many countries are beginning to recognize that nurses are vitally important to their cancer control efforts and nurses require specialized education and infrastructure support to make a substantial contribution. The purpose of this paper is to highlight the growth and development of cancer nursing in Asia. Several brief summaries are presented by nurse leaders in cancer care from several Asian countries. Their descriptions reflect illustrations of the leadership nurses are providing in cancer control practice, education, and research in their respective countries. The illustrations also reflect the potential for future development and growth of oncology nursing as a specialty given the many challenges nurses face across Asia. The development of relevant education programs following basic nursing preparation, the establishment of specialty organizations for oncology nurses, and engagement by nurses in policy activity have been influential factors in the growth of oncology nursing in Asia.

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.

An informatics infrastructure to catalyze cancer control research and practice.

A disconnect often exists between those with the expertise to manage and analyze complex, multi-source data sets, and the clinical, social services, advocacy, and public health professionals who can pose the most relevant questions and best apply the answers. We describe development and implementation of a cancer informatics infrastructure aimed at broadening the usability of community cancer data to inform cancer control research and practice; and we share lessons learned. We built a multi-level database known as The Ohio Cancer Assessment and Surveillance Engine (OH-CASE) to link data from Ohio's cancer registry with community data from the U.S. Census and other sources. Space-and place-based characteristics were assigned to individuals according to residential address. Stakeholder input informed development of an interface for generating queries based on geographic, demographic, and disease inputs and for outputting results aggregated at the state, county, municipality, or zip code levels. OH-CASE contains data on 791,786 cancer cases diagnosed from 1/1/2006 to 12/31/2018 across 88 Ohio counties containing 1215 municipalities and 1197 zip codes. Stakeholder feedback from cancer center community outreach teams, advocacy organizations, public health, and researchers suggests a broad range of uses of such multi-level data resources accessible via a user interface. OH-CASE represents a prototype of a transportable model for curating and synthesizing data to understand cancer burden across communities. Beyond supporting collaborative research, this infrastructure can serve the clinical, social services, public health, and advocacy communities by enabling targeting of outreach, funding, and interventions to narrow cancer disparities.

New directions in cancer and aging: State of the science and recommendations to improve the quality of evidence on the intersection of aging with cancer control.

BackgroundThe global population of older cancer survivors is growing. However, the intersections of aging‐related health risks across the cancer control continuum are poorly understood, limiting the integration of aging into cancer control research and practice. The objective of this study was to review the state of science and provide future directions to improve the quality of evidence in 6 priority research areas in cancer and aging.MethodsThe authors identified priority research areas in cancer and aging through an evidence‐based Research Jam process involving 32 investigators and trainees from multiple disciplines and research centers in aging and cancer; then, they conducted a narrative review of the state of the science and future directions to improve the quality of evidence in these research areas. Priority research areas were defined as those in which gaps in scientific evidence or clinical practice limit the health and well‐being of older adults with cancer.ResultsSix priority research areas were identified: cognitive and physical functional outcomes of older cancer survivors, sampling issues in studies of older cancer survivors, risk and resilience across the lifespan, caregiver support and well‐being, quality of care for older patients with cancer, and health disparities. Evidence in these areas could be improved through the incorporation of bias reduction techniques into longitudinal studies of older cancer survivors, novel data linkage, and improved representation of older adults in cancer research.ConclusionsThe priority research areas and methodologies identified here may be used to guide interdisciplinary research and improve the quality of evidence on cancer and aging.

Cancer and climate change.

The acute impact of climate change on human health is receiving increased attention, but little is known or appreciated about the effect of climate change on chronic diseases, particularly cancer. This Review provides a synopsis of what is known about climate change and the exposures it generates relevant to cancer. In the context of the world's cancer burden and the probable direction we could expect to follow in the absence of climate change, this scoping review of the literature summarises the effects that climate change is having on major cancers, from environmental exposures to ultraviolet radiation, air pollution, disruptions in the food and water supply, environmental toxicants, and infectious agents. Finally, we explore the effect of climate change on the possible disruption of health systems that have been essential to cancer control practice. We conclude with potential responses and opportunities for intervention.

Subsequent Cancer Prevention and Control Activities Among Low- and Middle-Income Country Participants in the US National Cancer Institute's Summer Curriculum in Cancer Prevention.

PURPOSEA dramatic shift in the burden of cancer from high-income countries to low- and middle-income countries (LMICs) is predicted to occur over the next few decades. An effective response requires a range of approaches to capacity building in cancer prevention and control in LMICs, including training of cancer prevention and control professionals. Toward this end, the US National Cancer Institute includes LMIC-based participants in its Summer Curriculum in Cancer Prevention, which is an annual, short-term in-person training program.METHODSIn 2015 and 2016, the US National Cancer Institute fielded a survey to all Summer Curriculum alumni who were based in LMICs when they participated in the program, between 1998 and 2015. Its aims were to learn about subsequent engagement in cancer prevention and control in LMICs and attribution of activities/accomplishments to participation in the Summer Curriculum in Cancer Prevention.RESULTSRespondents (N = 138) worked in academia/research (n = 61), health care (n = 41), and health policy/Ministries of Health (n = 36) in all six world regions. Most respondents (90.6%) worked in the same LMIC as when they participated in the Summer Curriculum in Cancer Prevention. When asked about activities/accomplishments completed as a result of participation, 92.8% reported at least one cancer prevention and control practice activity/accomplishment, 81.2% reported at least one cancer research activity/accomplishment, and 44.2% reported authoring one or more peer-reviewed publications. Reported ways that the Summer Curriculum in Cancer Prevention contributed to these activities/accomplishments were emphasizing a public health approach; focusing on research priorities, methods, and scientific writing; and highlighting the importance of research and publications. Finally, 79.7% of respondents reported using Summer Curriculum in Cancer Prevention materials to train others.CONCLUSIONThese findings have implications for the design of future training initiatives for LMIC-based cancer prevention and control professionals.

Challenges of using nationally representative, population-based surveys to assess rural cancer disparities

Population-based surveys provide important information about cancer-related health behaviors across the cancer care continuum, from prevention to survivorship, to inform cancer control efforts. These surveys can illuminate cancer disparities among specific populations, including rural communities. However, due to small rural sample sizes, varying sampling methods, and/or other study design or analytical concerns, there are challenges in using population-based surveys for rural cancer control research and practice. Our objective is three-fold. First, we examined the characterization of “rural” in four, population-based surveys commonly referenced in the literature: 1) Health Information National Trends Survey (HINTS); 2) National Health Interview Survey (NHIS); 3) Behavioral Risk Factor Surveillance System (BRFSS); and 4) Medical Expenditures Panel Survey (MEPS). Second, we identified and described the challenges of using these surveys in rural cancer studies. Third, we proposed solutions to address these challenges. We found that these surveys varied in use of rural-urban classifications, sampling methodology, and available cancer-related variables. Further, we found that accessibility of these data to non-federal researchers has changed over time. Survey data have become restricted based on small numbers (i.e., BRFSS) and have made rural-urban measures only available for analysis at Research Data Centers (i.e., NHIS and MEPS). Additionally, studies that used these surveys reported varying proportions of rural participants with noted limitations in sufficient representation of rural minorities and/or cancer survivors. In order to mitigate these challenges, we propose two solutions: 1) make rural-urban measures more accessible to non-federal researchers and 2) implement sampling approaches to oversample rural populations.

Going beyond the individual: how state-level characteristics relate to HPV vaccine rates in the United States

BackgroundThe human papillomavirus (HPV) vaccine is an underutilized cancer control practice in the United States. Although individual contextual factors are known to impact HPV vaccine coverage rates, the impact of macro-level elements are still unclear. The aim of this analysis was to use HPV vaccination rates to explore the underuse of an evidence-based cancer control intervention and explore broader-level correlates influencing completion rates.MethodsA comprehensive database was developed using individual-level date from the National Immunization Survey (NIS)-Teen (2016) and state-level data collected from publically available sources to analyze HPV vaccine completion. Multi-level logistic models were fit to identify significant correlates. Level-1 (individual) and level-2 (state) correlates were fitted to a random intercept model. Deviance and AIC assessed model fit and sampling weights were applied.ResultsThe analysis included 20,495 adolescents from 50 U.S. states and the District of Columbia. Teen age, gender, race/ethnicity, and maternal education were significant individual predictors of HPV completion rates. Significant state-level predictors included sex education policy, religiosity, and HPV vaccine mandate. States with the lowest HPV coverage rates were found to be conservative and highly religious. Little variation in vaccine exemptions and enacted sex and abstinence education polices were observed between states with high and low HPV vaccine coverage suggesting various contextual and situational factors impact HPV vaccine completion rates.ConclusionsGiven that gender, religiosity, political ideology, and education policies are predictors of HPV vaccine completion, the interaction and underlying mechanism of these factors can be used to address the underutilization of the HPV vaccine.

Barriers to Scale of Digital Health Systems for Cancer Care and Control in Last-Mile Settings.

The growing cancer epidemic is a major public health challenge globally but especially in low- and middle-income countries where patients often have to make long and complex journeys to receive care. Extending cancer prevention, diagnosis, and treatment to low- and middle-income countries through innovative solutions such as digital health systems is an urgent health priority. We contend that such digital systems will achieve success and scale only when existing gaps in cancer care and control policies and practices are addressed to strengthen health systems and improve outcomes. We call for concerted action to focus on the effective implementation of cancer care and control policies and practice in last-mile settings to improve pathways to care for people with and at risk for cancer.

Cancer control falls squarely within the province of the psychological sciences.

Against the background of cancer as a contemporary public health challenge, this article presents a selective overview of psychological science contributions to cancer control research, practice, and policy. Initial contributions were circumscribed to awareness campaigns and the assessment of emotional responses to diagnosis and treatment. As evidence linking certain behaviors to cancer risk and outcomes accumulated, psychology emerged as a "hub science" in the Nation's cancer control program. Despite substantial accomplishments, new societal trends further challenge our ability to reduce risk, incidence, and deaths from cancer and enhance quality of life for cancer survivors. Evidence generated from psychological research conducted within each cell of Pasteur's quadrant continues to be relevant and necessary for effective 21st-century approaches to cancer prevention and control at the individual, clinical, and population levels.

The cancer prevention and control research network: An interactive systems approach to advancing cancer control implementation research and practice.

Although cancer research has advanced at a rapid pace, a gap remains between what is known about how to improve cancer prevention and control (CPC) and what is implemented as best practices within health care systems and communities. The Cancer Prevention and Control Research Network (CPCRN), with more than 10 years of dissemination and implementation research experience, aims to accelerate the uptake and use of evidence-based CPC interventions. The collective work of the CPCRN has facilitated the analysis and categorization of research and implementation efforts according to the Interactive Systems Framework for Dissemination and Implementation (ISF), providing a useful heuristic for bridging the gap between prevention research and practice. The ISF authors have called for examples of its application as input to help refine the model. We provide examples of how the collaborative activities supported by the CPCRN, using community-engaged processes, accelerated the synthesis and translation of evidence, built both general and innovation-specific capacity, and worked with delivery systems to advance cancer control research and practice. The work of the CPCRN has provided real-world examples of the application of the ISF and demonstrated that synthesizing and translating evidence can increase the potential that evidence-based CPC programs will be used and that capacity building for both the support system and the delivery system is crucial for the successful implementation and maintenance of evidence-based cancer control. Adoption and implementation of CPC can be enhanced by better understanding ISF systems and intervening to improve them.

Using Digital Surveillance to Examine the Impact of Public Figure Pancreatic Cancer Announcements on Media and Search Query Outcomes

Announcements of cancer diagnoses from public figures may stimulate cancer information seeking and media coverage about cancer. This study used digital surveillance to quantify the effects of pancreatic cancer public figure announcements on online cancer information seeking and cancer media coverage. We compiled a list of public figures (N = 25) who had been diagnosed with or had died from pancreatic cancer between 2006 and 2011. We specified interrupted time series models using data from Google Trends to examine search query shifts for pancreatic cancer and other cancers. Weekly media coverage archived on Google News were also analyzed. Most public figures' pancreatic cancer announcements corresponded with no appreciable change in pancreatic cancer search queries or media coverage. In contrast, Patrick Swayze's diagnosis was associated with a 285% (95% confidence interval [CI]: 212 to 360) increase in pancreatic cancer search queries, though it was only weakly associated with increases in pancreatic cancer media coverage. Steve Jobs's death was associated with a 197% (95% CI: 131 to 266) increase in pancreatic cancer queries and a 3517% (95% CI: 2882 to 4492) increase in pancreatic cancer media coverage. In general, a doubling in pancreatic cancer-specific media coverage corresponded with a 325% increase in pancreatic cancer queries. Digital surveillance is an important tool for future cancer control research and practice. The current application of these methods suggested that pancreatic cancer announcements (diagnosis or death) by particular public figures stimulated media coverage of and online information seeking for pancreatic cancer.

Abstract P3-01-01: Insulin, Insulin-like Growth Factor-1 and cycling estrogen predict premenopausal mammographic density.

Abstract Background: Mammographic density, a strong biomarker for breast cancer risk, represents epithelial and stromal proliferation. Insulin and insulin-like growth factor (IGF)-1 are suggested to influence cellular proliferation, while estrogen is a key factor in breast cancer development. However, whether the effects of these hormones among premenopausal women are mediated through mammographic density is less known. Material and Methods: Fasting serum insulin, IGF-1, and IGF binding protein (IGFBP)-3 were assessed among 202 healthy premenopausal women (Norwegian Energy Balance and Breast cancer Aspects study-I (EBBA-I). Daily salivary levels of 17β-estradiol throughout an entire menstrual cycle were measured at the reproductive Ecology Laboratory, Harvard University, USA. Computer-assisted mammographic density (Madena) was obtained from digitized mammograms taken at day 7–12 of the menstrual cycle. Uni- and multivariable regression models were used to study the associations between hormones and premenopausal percent mammographic density. Results: Among women with a mean age of 30,7 years, a mean premenopausal percent mammographic density of 29.8 % was observed. Throughout the menstrual cycle when comparing women with a high percent mammographic density (≥28.5%) to women with a low percent mammographic density (&amp;lt;28.5%), we observed insulin, IGF-1 and IGFBP-3 independently and in combination with cycling 17β-estradiol to predict premenopausal percent mammographic density. We observed among women with either serum insulin ≥89 pmol/, IGF-1 ≥24 nmol/l, IGFBP-3 ≥ 100 nmol/l, having a high (≥28.5%) versus a low (&amp;lt;28.5%) percent mammographic density was associated with an increase in overall average 17β-estradiol of 4.0 %, 10.9 % and 14.9%, respectively. Moreover, we observed a higher adjusted Odds Ratio (OR) for having a high percent mammographic density for each standard deviation (SD) increase in overall average 17β -estradiol, insulin, IGF-1 and IGFBP-3: 17β-estradiol, 1.55 (1.06–2.27); insulin, 1.62 (0.76–3.48), IGF-1, 1.90 (1.10–3.27); IGFBP-3, 1.88 (1.05–3.37) (adjusted for age, body mass index-BMI kg/m2)). Conclusion: Our study supports that insulin, IGF-1 and IGFBP-3 independently, and in combination with cycling estrogen, predicts premenopausal mammographic density. These hormones may be important biomarkers in breast cancer control and clinical practice. Citation Information: Cancer Res 2012;72(24 Suppl):Abstract nr P3-01-01.
