Differences in up-to-date colorectal and cervical cancer screening rates by ethnicity and preferred language: An analysis across patient-, clinic-, and area-level data sources

Research objective

There is interest in using clinic- and area-level data to inform cancer control, but it is unclear what value these sources may add in combination with patient-level data sources. This study aimed to investigate associations of up-to-date colorectal and cervical cancer screenings at community health centers (CHCs) with ethnicity and language variables at patient-, clinic-, and area-levels, while exploring whether patient-level associations differed based on clinic-level patient language and ethnicity distributions.

Study design

This was a cross-sectional study using data from multiple sources, including electronic health records, clinic patient panel data, and area-level demographic data. The study sample included English-preferring Hispanic, Spanish-preferring Hispanic, English-preferring non-Hispanic, and non-English-preferring non-Hispanic patients eligible for either colorectal cancer (N = 98,985) or cervical cancer (N = 129,611) screenings in 2019 from 130 CHCs in the OCHIN network in CA, OR, and WA.

Population studied

The study population consisted of adults aged 45+ eligible for colorectal cancer screening and adults with a cervix aged 25-65 eligible for cervical cancer screening.

Principal findings

Spanish-preferring Hispanic patients were significantly more likely to be up-to-date with colorectal and cervical cancer screenings than other groups. Patients seen at clinics with higher concentrations of Spanish-preferring Hispanics were significantly more likely to be up-to-date, as were individuals residing in areas with higher percentages of Spanish-speaking residents. Differential associations between patient ethnicity and language and up-to-date colorectal cancer screenings were greater among patients seen at clinics with higher concentrations of Spanish-preferring Hispanics.

Conclusions

The findings highlight that Spanish-speaking Hispanics seen in CHCs have higher rates of up-to-date cervical and colorectal cancer screenings than other groups and that this relationship is stronger at clinics with higher percentages of Spanish-preferring Hispanic patients. Our findings suggest area-level variables are not good substitutions for patient-level data, but variables at the clinic patient panel-level are more informative.

Impact of individual level uncertainty of lung cancer polygenic risk score (PRS) on risk stratification

BACKGROUND

Although polygenic risk score (PRS) has emerged as a promising tool for predicting cancer risk from genome-wide association studies (GWAS), the individual-level accuracy of lung cancer PRS and the extent to which its impact on subsequent clinical applications remains largely unexplored.

METHODS

Lung cancer PRSs and confidence/credible interval (CI) were constructed using two statistical approaches for each individual: (1) the weighted sum of 16 GWAS-derived significant SNP loci and the CI through the bootstrapping method (PRS-16-CV) and (2) LDpred2 and the CI through posteriors sampling (PRS-Bayes), among 17,166 lung cancer cases and 12,894 controls with European ancestry from the International Lung Cancer Consortium. Individuals were classified into different genetic risk subgroups based on the relationship between their own PRS mean/PRS CI and the population level threshold.

RESULTS

Considerable variances in PRS point estimates at the individual level were observed for both methods, with an average standard deviation (s.d.) of 0.12 for PRS-16-CV and a much larger s.d. of 0.88 for PRS-Bayes. Using PRS-16-CV, only 25.0% of individuals with PRS point estimates in the lowest decile of PRS and 16.8% in the highest decile have their entire 95% CI fully contained in the lowest and highest decile, respectively, while PRS-Bayes was unable to find any eligible individuals. Only 19% of the individuals were concordantly identified as having high genetic risk (> 90th percentile) using the two PRS estimators. An increased relative risk of lung cancer comparing the highest PRS percentile to the lowest was observed when taking the CI into account (OR = 2.73, 95% CI: 2.12-3.50, P-value = 4.13 × 10-15) compared to using PRS-16-CV mean (OR = 2.23, 95% CI: 1.99-2.49, P-value = 5.70 × 10-46). Improved risk prediction performance with higher AUC was consistently observed in individuals identified by PRS-16-CV CI, and the best performance was achieved by incorporating age, gender, and detailed smoking pack-years (AUC: 0.73, 95% CI = 0.72-0.74).

CONCLUSIONS

Lung cancer PRS estimates using different methods have modest correlations at the individual level, highlighting the importance of considering individual-level uncertainty when evaluating the practical utility of PRS.

State of Cancer Control in South America: Challenges and Advancement Strategies

Cancer is a major public health problem in South America. The cancer mortality burden is increasing in the region due to its presentation at later stages, which is related to limited access to cancer care. This results in a noticeable inequity in provisions of cancer care including specialized screening programs, as well as cancer-related treatments such as personalized medicine, radiation therapy, palliative care, and survivorship services. Consequently, South America faces many challenges for cancer control, most of them deriving from a lack of funding and unequal distribution of resources and cancer services, affecting mostly the underserved populations in the region.

International burden of cancer deaths and years of life lost from cancer attributable to four major risk factors: a population-based study in Brazil, Russia, India, China, South Africa, the United Kingdom, and United States

Background

We provide a comprehensive view of the impact of alcohol consumption, tobacco smoking, excess body weight, and human papillomavirus (HPV) infection on cancer mortality and years of life lost (YLLs) in Brazil, Russia, India, China, South Africa, the United Kingdom (UK), and United States (US).

Methods

We collected population attributable fractions of the four risk factors from global population-based studies and applied these to estimates of cancer deaths in 2020 to obtain potentially preventable cancer deaths and their 95% confidence intervals (CIs). Using life tables, we calculated the number and age-standardised rates of YLLs (ASYR).

Findings

In Brazil, Russia, India, China, South Africa, the UK, and the US in 2020, an estimated 5.9 million (3.3 million-8.6 million) YLLs from cancer were attributable to alcohol consumption, 20.8 million (17.0 million-24.6 million) YLLs to tobacco smoking, 3.1 million (2.4 million-3.8 million) YLLs to excess body weight, and 4.0 million (3.9 million-4.2 million) YLLs to HPV infection. The ASYR from cancer due to alcohol consumption was highest in China (351.4 YLLs per 100,000 population [95% CI 194.5-519.2]) and lowest in the US (113.5 [69.6-157.1]) and India (115.4 [49.7-172.7). For tobacco smoking, China (1159.9 [950.6-1361.8]) had the highest ASYR followed by Russia (996.8 [831.0-1154.5). For excess body weight, Russia and the US had the highest ASYRs (385.1 [280.6-481.2] and 369.4 [299.6-433.6], respectively). The highest ASYR due to HPV infection was in South Africa (457.1 [453.3-462.6]). ASYRs for alcohol consumption and tobacco smoking were higher among men than women, whereas women had higher ASYRs for excess body weight and HPV infection.

Interpretation

Our findings demonstrate the importance of cancer control efforts to reduce the burden of cancer death and YLLs due to modifiable cancer risk factors and promote the use of YLLs to summarise disease burden.

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.

Global prevalence and content of information about alcohol use as a cancer risk factor on Twitter

OBJECTIVES

Alcohol use is a major risk factor for several forms of cancer, though many people have limited knowledge of this link. Public health communicators and cancer advocates desire to increase awareness of this link with the long-term goal of reducing cancer burden. The current study is the first to examine the prevalence and content of information about alcohol use as a cancer risk on social media internationally.

METHODS

We used a three-phase process (hashtag search, dictionary-based auto-identification of content, and human coding of content) to identify and evaluate information from Twitter posts between January 2019 and December 2021.

RESULTS

Our hashtag search retrieved a large set of cancer-related tweets (N = 1,122,397). The automatic search process using an alcohol dictionary identified a small number of messages about cancer that also mentioned alcohol (n = 9061, 0.8%), a number that got small after adjusting for human coded estimates of the dictionary precision (n = 5927, 0.5%). When cancer-related messages also mentioned alcohol, 82% (n = 1003 of 1225 examined through human coding) indicated alcohol use as a risk factor. Coding found rare instances of problematic information (e.g., promotion of alcohol, misinformation) in messages about alcohol use and cancer.

CONCLUSIONS

Few social media messages about cancer types that can be linked to alcohol mention alcohol as a cancer risk factor. If public health communicators and cancer advocates want to increase knowledge and understanding of alcohol use as a cancer risk factor, efforts will need to be made on social media and through other communication platforms to increase exposure to this information over time.

Project ECHO for Cancer Care: a Scoping Review of Provider Outcome Evaluations

The Project ECHO model of telementoring has been used for the past 10 years to expand access to specialized cancer care. This scoping review identifies evidence for the model's ability to improve provider outcomes, synthesizing findings from existing studies within Moore et al.'s (2009) framework for continuing medical education outcomes. We search two large research databases and a collection maintained by Project ECHO staff for articles that focus on cancer ECHO programs, involve primary data collection, and were published between December 1, 2016, and November 30, 2021. We identified 25 articles for inclusion in our scoping review. Most articles reported results for outcomes related to program participation: attendance, satisfaction, and learning. Yet, just under half reported changes in provider practices. Results demonstrate widespread participation and improved learning resulting from ECHO programs focused on cancer care. There is also evidence of improved practices related to HCV vaccination and palliative care. We highlight examples of best practices as well as opportunities to improve provider outcome evaluations for cancer ECHO programs.

Integrating a focus on health equity in implementation science: Case examples from the national cancer institute's implementation science in cancer control centers (ISC3) network

Background

A Health Equity Task Force (HETF) of members from seven Centers funded by the National Cancer Institute's (NCI) Implementation Science in Cancer Control Centers (ISC3) network sought to identify case examples of how Centers were applying a focus on health equity in implementation science to inform future research and capacity-building efforts.

Methods

HETF members at each ISC3 collected information on how health equity was conceptualized, operationalized, and addressed in initial research and capacity-building efforts across the seven ISC3 Centers funded in 2019-2020. Each Center completed a questionnaire assessing five health equity domains central to implementation science (e.g., community engagement; implementation science theories, models, and frameworks (TMFs); and engaging underrepresented scholars). Data generated illustrative examples from these five domains.

Results

Centers reported a range of approaches focusing on health equity in implementation research and capacity-building efforts, including (1) engaging diverse community partners/settings in making decisions about research priorities and projects; (2) applying health equity within a single TMF applied across projects or various TMFs used in specific projects; (3) evaluating health equity in operationalizing and measuring health and implementation outcomes; (4) building capacity for health equity-focused implementation science among trainees, early career scholars, and partnering organizations; and (5) leveraging varying levels of institutional resources and efforts to engage, include, and support underrepresented scholars.

Conclusions

Examples of approaches to integrating health equity across the ISC3 network can inform other investigators and centers' efforts to build capacity and infrastructure to support growth and expansion of health equity-focused implementation science.

Addressing cancer care in low- to middle-income countries: a call for sustainable innovations and impactful research

Most new cancer cases are currently arising in low- and middle-income countries, where their outcomes are significantly poorer compared to high-income countries. Innovative solutions are imperiously needed to prevent, detect early, and manage cancer in low- and middle-income countries, aiming to improve the chances of survival.

Implementing and monitoring the right to health in breast cancer: selection of indicators using a Delphi process

BACKGROUND

Women with breast cancer have different chances of surviving their disease, depending on where they live. Variations in survival may stem from unequal access to prompt diagnosis, treatment and care. Implementation of the right to health may help remedy such inequalities. The right to health is enshrined in international human rights law, notably Article 12 of the International Covenant on Economic, Social and Cultural Rights. A human rights-based approach to health requires a robust, just and efficient health system, with access to adequate health services and medicines on a non-discriminatory basis. However, it may prove challenging for health policymakers and cancer management specialists to implement and monitor this right in national health systems.

METHOD

This article presents the results of a Delphi study designed to select indicators of implementation of the right to health to inform breast cancer care and management. In a systematic process, 13 experts examined an initial list of 151 indicators.

RESULTS

After two rounds, 54 indicators were selected by consensus, three were rejected, three were added, and 97 remained open for debate. For breast cancer, right-to-health features selected as worth implementing and monitoring included the formal recognition of the right to health in breast cancer strategies; a population-based screening programme, prompt diagnosis, strong referral systems and limited waiting times; the provision of palliative, survivorship and end-of-life care; the availability, accessibility, acceptability and quality (AAAQ) of breast cancer services and medicines; the provision of a system of accountability; and the collection of anonymised individual data to target patterns of discrimination.

CONCLUSION

We propose a set of indicators as a guide for health policy experts seeking to design national cancer plans that are based on a human rights-based approach to health, and for cancer specialists aiming to implement principles of the right to health in their practice. The 54 indicators selected may be used in High-Income Countries, or member states of the OECD who also have signed the International Covenant on Economic, Social and Cultural Rights to monitor progress towards implementation of the right to health for women with breast cancer.

Perceptions about the causes and treatment of cancer - A cross-sectional survey of university students in Ghana

Cancer awareness campaigns in Ghana and many parts of the world have gathered pace in recent years. Despite this encouraging trend, there has been no significant reduction in stigma in Ghana. This study investigated the role of beliefs about the causes of cancer in stigmatization and perceptions about treatment. Using standardized scales deployed in a survey, the study measured student perceptions about the causes of cancer, stigmatization, and opinion about the possibility of treating cancer. 225 students were sampled from two universities in the Ghanaian capital of Accra. The study used multiple linear regression and a logistic regression to answer two research questions. These asked whether beliefs in the mythical causes of cancer are associated with stigma towards cancer and whether this stigma is associated with the belief that cancer cannot be treated. The findings point to the association between perceived causes of cancer and stigma. Stigmatization was associated with the belief that cancer could not be treated. The findings imply that the perceived causes of cancer are associated with stigma and should thus be addressed by campaigners. Educating the public about the causes of cancer and addressing some of the myths can help reduce stigma and correct misperceptions about treatment.

Strengthening cancer control in the South Pacific through coalition-building: a co-design framework

Background

Cancer is a significant problem for the South Pacific region due to a range of complex health challenges. Currently gaps in diagnosis, treatment and palliative care are significant, and while governmental commitment is strong, economic constrains limit health system strengthening. Alliances have been successful in strengthening non-communicable disease and cancer control policy and services in resource constrained settings. A regional coalition approach has therefore been recommended as an effective solution to addressing many of the challenges for cancer control in the South Pacific. However, evidence regarding the effective mechanisms for development of alliances or coalitions is scarce. This study aimed to 1) create a Coalition Development Framework; 2) assess the use of the Framework in practice to co-design a South Pacific Coalition.

Methods

Creation of the Coalition Development Framework commenced with a scoping review and content analysis of existing literature. Synthesis of key elements formed an evidence-informed step-by-step guide for coalition-building. Application of the Framework comprised consultation and iterative discussions with key South Pacific cancer control stakeholders in Fiji, New Caledonia, Papua New Guinea, Samoa and Tonga. Concurrent evaluation of the Framework utilising Theory of Change (ToC) and qualitative analysis of stakeholder consultations was undertaken.

Findings

The finalised Coalition Development Framework comprised four phases with associated actions and deliverables: engagement, discovery, unification, action and monitoring. Application of the Framework in the South Pacific identified overwhelming support for a Cancer Control Coalition through 35 stakeholder consultations. Framework phases enabled stakeholders to confirm coalition design and purpose, strategic imperatives, structure, local foundations, barriers and facilitators, and priorities for action. ToC and thematic consultation analysis confirmed the Framework to be an effective mechanism to drive engagement, unification and action in alliance-building.

Interpretation

A Coalition to drive cancer control has significant support among key Pacific stakeholders, and establishment can now be commenced. Importantly results confirm the effective application of the Coalition Development Framework in an applied setting. If momentum is continued, and a regional South Pacific Coalition established, the benefits in reducing the burden of cancer within the region will be substantial.

Cancer survivorship experiences in Utah: an evaluation assessing indicators of survivors' quality of life, health behaviors, and access to health services

PURPOSE

The 2016-2020 Utah Comprehensive Cancer Prevention and Control Plan prioritized strategies to address cancer survivorship experiences. In this paper we present estimates for nine indicators evaluating these priorities, trends over time, and assess disparities in survivorship experiences across demographic subgroups.

METHODS

We surveyed a representative sample of Utah cancer survivors diagnosed between 2012 and 2019 with any reportable cancer diagnosis. We calculated weighted percentages and 95% confidence intervals (CI) for each indicator. We assessed change over time using a test for trend across survey years in a logistic regression model and used Rao-Scott F-adjusted chi-square tests to test the association between demographic characteristics and each survivorship indicator.

RESULTS

Most of the 1,793 respondents (93.5%) reported their pain was under control, 85.7% rated their overall health as good, very good, or excellent, but 46.5% experienced physical, mental, or emotional limitations. Only 1.7% of survivors aged 75 or older were current smokers, compared to 5.8% of 65-74-year-olds and 7.9% of survivors aged 55-74 (p < 0.006). No regular physical activity was reported by 20.6% and varied by survivor age and education level. The proportion who received a survivorship care plan increased from 34.6% in 2018 to 43.0% in 2021 (p = 0.025). However, survivors under age 55 were significantly less likely to receive a care plan than older survivors.

CONCLUSION

This representative survey of cancer survivors fills a gap in understanding of the cancer survivorship experience in Utah. Results can be used to evaluate and plan additional interventions to improve survivorship quality of life.

Cancer pattern in Varanasi district from Uttar Pradesh state of India, a foundation for cancer control based on the first report of the population-based cancer registry

Background

The cancer registry provides reliable data from the population. In this article, we provide cancer burden and its patterns from the Varanasi district.

Methods

The method adopted by the Varanasi cancer registry is community interaction along with regular visits to more than 60 sources to collect data on cancer patients. The cancer registry was established by the Tata Memorial Centre, Mumbai, in 2017 covering 4 million population (57% rural and 43% urban population).

Results

The registry has recorded 1,907 incidence cases (1,058 male and 849 female). The age-adjusted incidence rate per 100,000 population in male and female of Varanasi district is 59.2 and 52.1, respectively. One in 15 male and one in 17 female are at risk of developing the disease. Mouth and tongue cancers are the predominant cancers in male, whereas breast, cervix uteri, and gallbladder are the leading cancer sites among the female. In female, cervix uteri cancer is significantly higher (double) in rural areas when compared with urban areas (rate ratio [RR] 0.5, 95% confidence interval [CI; 0.36, 0.72]), whereas in male, mouth cancer is higher in urban areas when compared with rural areas (RR 1.4, 95% CI [1.11, 1.72]). More than 50% of cancer cases in male are due to tobacco consumption. There may be underreporting of the cases.

Conclusion

The results of the registry warrant policies and activities related to early detection services for the mouth, cervix uteri, and breast cancers. The Varanasi cancer registry is the foundation for cancer control and will play an important role in the evaluation of the interventions.

Creating research-ready partnerships: the initial development of seven implementation laboratories to advance cancer control

BACKGROUND

In 2019-2020, with National Cancer Institute funding, seven implementation laboratory (I-Lab) partnerships between scientists and stakeholders in 'real-world' settings working to implement evidence-based interventions were developed within the Implementation Science Centers in Cancer Control (ISC3) consortium. This paper describes and compares approaches to the initial development of seven I-Labs in order to gain an understanding of the development of research partnerships representing various implementation science designs.

METHODS

In April-June 2021, members of the ISC3 Implementation Laboratories workgroup interviewed research teams involved in I-Lab development in each center. This cross-sectional study used semi-structured interviews and case-study-based methods to collect and analyze data about I-Lab designs and activities. Interview notes were analyzed to identify a set of comparable domains across sites. These domains served as the framework for seven case descriptions summarizing design decisions and partnership elements across sites.

RESULTS

Domains identified from interviews as comparable across sites included engagement of community and clinical I-Lab members in research activities, data sources, engagement methods, dissemination strategies, and health equity. The I-Labs use a variety of research partnership designs to support engagement including participatory research, community-engaged research, and learning health systems of embedded research. Regarding data, I-Labs in which members use common electronic health records (EHRs) leverage these both as a data source and a digital implementation strategy. I-Labs without a shared EHR among partners also leverage other sources for research or surveillance, most commonly qualitative data, surveys, and public health data systems. All seven I-Labs use advisory boards or partnership meetings to engage with members; six use stakeholder interviews and regular communications. Most (70%) tools or methods used to engage I-Lab members such as advisory groups, coalitions, or regular communications, were pre-existing. Think tanks, which two I-Labs developed, represented novel engagement approaches. To disseminate research results, all centers developed web-based products, and most (n = 6) use publications, learning collaboratives, and community forums. Important variations emerged in approaches to health equity, ranging from partnering with members serving historically marginalized populations to the development of novel methods.

CONCLUSIONS

The development of the ISC3 implementation laboratories, which represented a variety of research partnership designs, offers the opportunity to advance understanding of how researchers developed and built partnerships to effectively engage stakeholders throughout the cancer control research lifecycle. In future years, we will be able to share lessons learned for the development and sustainment of implementation laboratories.

Colorectal Cancer in Saudi Arabia: The Way Forward

Colorectal cancer is the most common cancer in Saudi males and the second most common cancer in Saudi females with increasing incidence throughout the last four decades. Although the disease incidence is on the rise, still there is no systemic screening for colorectal cancer in the Saudi population. Early onset colorectal cancer is common in the Saudi population and up to 50% in Saudi patients diagnosed at late stages with regional and distal metastasis. Therefore, more efforts are required to control the disease in the Kingdom of Saudi Arabia. In this regard,  systematic work at national level is highly required to make  colorectal cancer screening for population at risk part of the routine primary health care activities. This paper highlights the current situation of colorectal cancer in the Kingdom of Saudi Arabia with relation to incidence, mortality and morbidity in addition to the disease control efforts going on. Finally, some recommendations are provided to strengthen the control program of colorectal cancer.

Survival trends in solid cancers in the Nordic countries through 50 years

AIMS

Global survival studies in cancer have generally shown favourable development, but studies over extended periods on populations for which medical care is essentially free of charge are lacking.

METHODS

We analyse relative 1- and 5-year survival in all solid cancers in Denmark, Finland, Norway and Sweden through a 50-year period (1970-2019) using the NORDCAN database.

RESULTS

The most recent survival results showed three types of patterns. Cancers of very good survival (5-year survival ∼90%) included common cancers of the breast and prostate, as well as melanoma. The second pattern, which included the largest number of cancers, showed 1-year survival of over 80% and a drop of 10-20 % units in 5-year survival. The third group consisted of eight fatal cancers, sharing poor 5-year survival (around 20%). The 50-year improvement in 1-year survival was largest (30-50 % units) in kidney, brain, gallbladder and liver cancers, and (∼30%) in colon, small intestinal, lung, pleural, pancreas and ovarian cancers. Improvements in 5-year survival were highest (40-50 % units) in prostate and kidney cancers but remained at 10-20 % units for the eight fatal cancers. Survival showed significant sex preferences for a few cancers.

CONCLUSIONS

The analysis over a half-century confirms the progress in 'real-world' cancer control, and in 84% of patients 5-year survival was &gt;60%. Metastases remain a challenge, placing the emphasis on early detection before metastasis occurs. Novel therapies, such as immunotherapy which has curative potential even against metastatic disease, are needed.

Oncology Patient Navigation Training: Results of a Pilot Study in Nigeria

The purpose of this pilot study was to test the efficacy of an online navigation training designed to improve trainee confidence in performing core patient navigation tasks among Nigerian nurses, patient advocates, and cancer survivors. The online training originally designed for US patient navigators was supplemented by a Nigerian health system interactive session. Nurses, advocates, and cancer survivors (n = 36) were recruited to take a patient navigation training from May-June 2020 that consisted of approximately 10 h of online content and a 2-h online session. Trainees enrolled in the no-cost training and completed all 20 lessons. Post-intervention interviews (n = 10) were conducted to garner feedback from trainees. Trainees reported statistically significant improvements in confidence in performing core competencies for cancer patient navigation across all lessons. Feedback was generally positive with trainees expressing satisfaction and appreciation for the training. Challenges included lack of free, broadband Internet access leading to data streaming costs on the part of trainees. Trainees who were oncology nurses indicated that funding, time, and staffing constraints could impede implementation of patient navigation in practice; but these trainees also expressed new ideas for patient support and advocacy to alleviate some barriers to care for their patients as a result of the training. This study provided preliminary data that supports the feasibility and utility of using the GW Cancer Center online patient navigation training in non-US settings. Small adaptations to training content and technological delivery could improve access to the training experience. Implementation science approaches are needed to inform sustainable patient navigation in low-resource settings.

Cancer incidence and spectrum among Uygurs in Hotan District in China

Cancer is the leading cause of death in China and a significant public health problem with increasing incidence and fatality rates. The Han nationality is the main ethnic group in China, and many reports on the epidemiology of cancers in Han nationality are published. However no studies report the cancer spectrum of Uygurs which are one of the minority nationalities in China. Hence, we present incidence and mortality numbers of different cancers for the Uygur patients for the period 2018-2020 in Hotan District where Uygur population accounts for 99 %. During the 3-year study period, 2509 new Uygur cancer cases were registered, comprising 774 men and 1735 women. Cervical cancer was the most common, followed by esophageal, breast, gastric and colorectal cancers. The most common cancers in women and men were cervical cancer and esophageal cancer, respectively. In conclusion, the cancer spectrum in Hotan is different from other regions of China and our research revealed the cancer incidence in Hotan, which could help us to take appropriate measures to reduce the incidence rate.

Results of the George Washington University cancer center's comprehensive cancer control cancer communication mentorship program and implications for future practice

PURPOSE

The Comprehensive Cancer Control Cancer Communication Mentorship Program ("Mentorship Program") was created by the George Washington University Cancer Center (GWCC) to provide technical assistance (TA) in implementing evidence-based cancer screening communication interventions and support networking for comprehensive cancer control (CCC) professionals. The Mentorship Program matched entry-to mid-level CCC professionals with health communication and/or CCC experts and offered monthly web-based discussions with academic researchers and practitioners who shared their knowledge and provided applied learning opportunities throughout mentees' project planning, implementation and evaluation. The program objective was for mentees to improve health communication skills and apply evidence-based knowledge to reduce the burden of cancer.

METHODS

A mixed methods evaluation was conducted, including a qualitative description of each project and its outcomes as well as quantitative measures of satisfaction with the program and self-rated changes in competence.

RESULTS

Mentees represented the following locations: New Jersey, Arkansas, Michigan, West Virginia, and Republic of Palau. Project topics ranged from increasing Human papillomavirus (HPV) vaccinations to increasing screening uptake for colorectal cancer, lung cancer, cervical cancer, and breast cancer. Evaluation results from pre- and post-program communication competency self-assessments and mid- and post-program surveys revealed that the Mentorship Program advanced personal and professional goals and improved public health communication skills.

CONCLUSION

The Mentorship Program achieved its objectives for peer networking and offering expert TA in cancer prevention and control communication, offering a promising model for others involved in supporting implementation of evidence in practice.

An informatics infrastructure to catalyze cancer control research and practice

PURPOSE

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.

METHODS

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.

RESULTS

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.

CONCLUSION

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.

An evaluation of an Extension for Community Healthcare Outcomes (ECHO) intervention in cancer prevention and survivorship care

To improve cancer care in Indiana, a telementoring program using the Extension for Community Healthcare Outcomes (ECHO) model was introduced in September 2019 to promote best-practice cancer prevention, screening, and survivorship care by primary care providers (PCPs). The aim of this study was to evaluate the program’s educational outcomes in its pilot year, using Moore’s Evaluation Framework for Continuing Medical Education and focusing on the program’s impact on participants’ knowledge, confidence, and professional practice. We collected data in 22 semi-structured interviews (13 PCPs and 9 non-PCPs) and 30 anonymous one-time surveys (14 PCPs and 16 non-PCPs) from the program participants (hub and spoke site members), as well as from members of the target audience who did not participate. In the first year, average attendance at each session was 2.5 PCPs and 12 non-PCP professionals. In spite of a relatively low PCP participation, the program received very positive satisfaction scores, and participants reported improvements in knowledge, confidence, and practice. Both program participants and target audience respondents particularly valued three features of the program: its conversational format, the real-life experiences gained, and the support received from a professional interdisciplinary community. PCPs reported preferring case discussions over didactics. Our results suggest that the Cancer ECHO program has benefits over other PCP-targetted cancer control interventions and could be an effective educational means of improving cancer control capacity among PCPs and others. Further study is warranted to explain the discrepancies among study participants’ perceptions of the program’s strengths and the relatively low PCP participation before undertaking a full-scale effectiveness study.

Collaboration networks of the implementation science centers for cancer control: a social network analysis

BACKGROUND

Multi-center research initiatives offer opportunities to develop and strengthen connections among researchers. These initiatives often have goals of increased scientific collaboration which can be examined using social network analysis.

METHODS

The National Cancer Institute (NCI)-funded Implementation Science Centers in Cancer Control (ISC3) initiative conducted an online social network survey in its first year of funding (2020) to (1) establish baseline network measures including the extent of cross-center collaboration and (2) assess factors associated with a network member's access to the network such as one's implementation science (IS) expertise. Members of the seven funded centers and NCI program staff identified collaborations in planning/conducting research, capacity building, product development, scientific dissemination, and practice/policy dissemination.

RESULTS

Of the 192 invitees, 182 network members completed the survey (95%). The most prevalent roles were faculty (60%) and research staff (24%). Almost one-quarter (23%) of members reported advanced expertise in IS, 42% intermediate, and 35% beginner. Most members were female (69%) and white (79%). One-third (33%) of collaboration ties were among members from different centers. Across all collaboration activities, the network had a density of 14%, suggesting moderate cohesion. Degree centralization (0.33) and betweenness centralization (0.07) measures suggest a fairly dispersed network (no single or few central member(s) holding all connections). The most prevalent and densely connected collaboration was in planning/conducting research (1470 ties; 8% density). Practice/policy dissemination had the fewest collaboration, lowest density (284 ties' 3% density), and the largest number of non-connected members (n=43). Access to the ISC3 network varied significantly depending on members' level of IS expertise, role within the network, and racial/ethnic background. Across all collaboration activities, most connected members included those with advanced IS expertise, faculty and NCI staff, and Hispanic or Latino and white members.

CONCLUSIONS

Results establish a baseline for assessing the growth of cross-center collaborations, highlighting specific areas in need of particular growth in network collaborations such as increasing engagement of racial and ethnic minorities and trainees or those with less expertise in IS.

Methods and implementation of a Hospital-Based Cancer Registry in a major city in a low-to middle-income country: the case of Cali, Colombia

PURPOSE

To describe our experience upon developing and implementing a hospital-based cancer registry (HBCR) in a quaternary-level of care private non-profit academic medical center in Cali, Colombia.

METHODS

HBCRs capture, in a given institution, every single patient with a confirmed malignancy. In this study, all cases evaluated between 2014 and 2018 were included in the HBCR. In compliance with the International Agency for Research on Cancer recommendations, cases were classified as analytic or non-analytic. Data derived from an exhaustive selection of patients was stored in a computing platform owned by the institution, meeting the 2016 Facility Oncology Registry Data Standards recommendations. Quality control was performed by evaluating comparability, timeliness, validity, and completeness.

RESULTS

A total of 24,405 new cases were registered between 2014 and 2018, from which 4253 (17.4%) died. Among all cases, based on the anatomic location, most common malignancies were breast (n = 1554), thyroid (n = 1346), hematolymphoid (n = 1251), prostatic (n = 805), and colorectal (n = 624). The behavior of the new cases was consistent with an incremental trend.

CONCLUSION

Upon implementing the HBCR, major challenges were identified (i.e., a precise definition of cases, the development of processes for capturing new cases, a standardized data collection strategy, and carrying-out an appropriate patient follow-up). Based on our experience, the success of an HBCR largely relies on the interest from the institution, the engagement of stakeholders and financial support, that is, it depends on the adequate access over time to funding, technological, and staffing resources.

Robust p53 recovery using chattering free sliding mode control and a gain-scheduled modified Utkin observer

p53 protein plays an essential role in protecting the genomic integrity of mammalian cells. A drastic decrease in the amount of p53 protein has been observed in cancerous cells. By using Nutlin-based small molecule drugs, the concentration of p53 can be restored to the desired level. This paper presents the drug-dosage design for p53 pathway, based on a control-oriented nonlinear model. A chattering free sliding mode control (CFSMC) strategy is employed to track the desired trajectory of p53 concentration for both of its dynamic behaviors, i.e., sustained and oscillatory responses. A gain-scheduled modified Utkin observer (GSMUO) is designed for robust state reconstruction and disturbance estimation. The simulation results show that CFSMC and GSMUO exhibit desired robustness and performance properties in the presence of parametric variations, an input disturbance and measurement noise. Moreover, a comprehensive simulation study, along with a detailed quantitative analysis is performed to compare CFSMC-GSMUO with four different techniques: a sliding mode control (SMC) with an equivalent control based sliding mode observer (SMO) and GSMUO, respectively, and a dynamic sliding mode control (DSMC) with SMO and GSMUO, respectively. The analysis demonstrates that the tracking error and utilization of the control energy is the least in the case of CFSMC-GSMUO as compared to its counterparts.

A tribute to Robert Croyle, PhD, Director, Division of Cancer Control and Population Sciences

At the beginning of Dr. Robert Croyle's 18th and final year as director of the National Cancer Institute's (NCI) Division of Cancer Control and Population Sciences (DCCPS), before his retirement in December 2021, it is fitting to review some of his and the division's many accomplishments and pay tribute to him as one of the government's most effective leaders. The focus of this article is on Dr. Croyle's contributions in the behavioral and related domains and his and the division's impact on the landscape of cancer control and population sciences. Dr. Croyle joined DCCPS in 1998 as associate director for behavioral research. He became acting director of DCCPS in 2001 and then director in 2003. DCCPS is a formidable NCI division, with broad mandates and responsibilities and many partners from multiple sectors. The division conducts and supports an integrated program of the highest-quality genetic, epidemiological, behavioral, social, applied, survivorship, surveillance, and health care delivery cancer research. The division's notable successes in implementation science and the dissemination of evidence-based findings and products, use of cancer research consortia, and partnerships across National Institutes of Health and with external federal and nongovernmental organizations are among many that reflect Dr. Croyle's visionary leadership.

Embracing policy implementation science to ensure translation of evidence to cancer control policy

Although health-related policies are abundant, efforts to understand how to ensure that these policies serve as an effective vehicle for translating scientific evidence are relatively sparse. This paper explores how policy-focused implementation science (IS) may contribute to understanding the translation of scientific evidence to health-related policy in governmental and nongovernmental sectors. Expanding the focus of implementation science in cancer control could systematically address policy to both increase the use of scientific evidence in general and to address health equity. In this Commentary, we look to relevant work outside of IS that could be informative, most notably from the field of political science. We propose several ideas for future research that could help move the field of policy implementation science in cancer control in the USA forward. Although most efforts to increase uptake of the scientific evidence base reference translation to "practice and policy," there has been relatively little emphasis in the USA on implementation at the policy level, especially related to cancer control. If we are to achieve the full benefits of scientific discovery on population and public health, we will need to consider policy as a critical mechanism by which evidence can be translated to practice. We have a robust set of methods within implementation science that are increasing the pace of adoption and maintenance of evidence-based programs in a variety of settings. Building on these efforts, the time is right to expand our focus to include policy implementation.

Emerging digital technologies in cancer treatment, prevention, and control

The very first issue of the journal of Translational Behavioral Medicine (TBM) was dedicated, in part, to the theme of Health Information Technology as a platform for evidence implementation. The topic was timely: legislation in the USA was passed with the intent of stimulating the adoption of electronic health records; mobile smartphones, tablets, and other devices were gaining traction in the consumer market, while members within the Society of Behavioral Medicine were gaining scientific understanding on how to use these tools to effect healthy behavior change. For the anniversary issue of TBM, we evaluated the progress and problems associated with deploying digital health technologies to support cancer treatment, prevention, and control over the last decade. We conducted a narrative review of published literature to identify the role that emerging digital technologies may take in achieving national and international objectives in the decade to come. We tracked our evaluation of the literature across three phases in the cancer control continuum: (a) prevention, (b) early detection/screening, and (c) treatment/survivorship. From our targeted review and analyses, we noted that significant progress had been made in the adoption of digital health technologies in the cancer space over the past decade but that significant work remains to be done to integrate these technologies effectively into the cancer control systems needed to improve outcomes equitably across populations. The challenge for the next 10 years is inherently translational.

Future directions for implementation science at the National Cancer Institute: Implementation Science Centers in Cancer Control

The National Cancer Institute (NCI) Cancer Moonshot initiative seeks to accelerate cancer research for the USA. One of the scientific priorities identified by the Moonshot's Blue Ribbon Panel (BRP) of scientific experts was the implementation of evidence-based approaches. In September 2019, the NCI launched the Implementation Science Centers in Cancer Control (ISC3 or "Centers") initiative to advance this Moonshot priority. The vision of the ISC3 is to promote the development of research centers to build capacity and research in high-priority areas of cancer control implementation science (e.g., scale-up and spread, sustainability and adaptation, and precision implementation), build implementation laboratories within community and clinical settings, improve the state of measurement and methods, and improve the adoption, implementation, and sustainment of evidence-based cancer control interventions. This paper highlights the research agenda, vision, and strategic direction for these Centers and encourages transdisciplinary scientists to learn more about opportunities to collaborate with these Centers.

Communication research at the National Cancer Institute, 2013-2019: a grant portfolio analysis

PURPOSE

To analyze communication-focused grants funded by the National Cancer Institute (NCI) between fiscal years 2013 and 2019 to provide insight into the characteristics of funded projects and identify promising areas for future research.

METHODS

iSearch, a portfolio analysis tool, was queried to identify communication-related grants funded by NCI. Abstracts and specific aims were coded for key study characteristics. 344 unique competing grants with a substantial communication component were included in the final analysis. SAS version 9.4 was used to calculate code frequencies.

RESULTS

Most communication grants focused on cancer prevention (n = 197), with fewer targeting diagnosis, treatment, survivorship, or end-of-life. Tobacco product use was the most frequently addressed topic (n = 128). Most grants targeted or measured outcomes at the individual (n = 332) or interpersonal level (n = 127). Cancer patients/survivors (n = 101) and healthcare providers (n = 63) were often the population of focus, while caregivers or those at increased risk for cancer received less attention. Studies were often based in healthcare settings (n = 125); few studies were based in schools or worksites. Many grants employed randomized controlled trials (n = 168), but more novel methods, like optimization trials, were uncommon.

CONCLUSION

NCI's support of health communication research covers a diverse array of topics, populations, and methods. However, the current analysis also points to several promising opportunities for future research, including efforts focused on communication at later stages of the cancer control continuum and at multiple levels of influence, as well as studies that take advantage of a greater diversity of settings and leverage novel methodological approaches.

Health Information National Trends Survey (HINTS.gov)

As an initiative of the National Cancer Institute (NCI), the Health Information National Trends Survey (HINTS) is a recurring, cross-sectional national survey to assess how adults in the United States access and use health information, their perceptions of health risk, and their participation in health-promoting or health-risking behaviors with an emphasis on cancer-related topics. The HINTS website (<https://hints.cancer.gov>) gives free public access to all HINTS survey materials, data, and analyses. HINTS data can be used to inform the design and evaluation of cancer control and other health related communication programs, and serve as a starting point for further independent research. This article provides an overview of the resources available at (<https://hints.cancer.gov>) and suggests factors to bear in mind while navigating the site.

Optimizing Implementation in Cancer Control (OPTICC): protocol for an implementation science center

BACKGROUND

Evidence-based interventions (EBIs) could reduce cervical cancer deaths by 90%, colorectal cancer deaths by 70%, and lung cancer deaths by 95% if widely and effectively implemented in the USA. Yet, EBI implementation, when it occurs, is often suboptimal. This manuscript outlines the protocol for Optimizing Implementation in Cancer Control (OPTICC), a new implementation science center funded as part of the National Cancer Institute Implementation Science Consortium. OPTICC is designed to address three aims. Aim 1 is to develop a research program that supports developing, testing, and refining of innovative, efficient methods for optimizing EBI implementation in cancer control. Aim 2 is to support a diverse implementation laboratory of clinical and community partners to conduct rapid, implementation studies anywhere along the cancer care continuum for a wide range of cancers. Aim 3 is to build implementation science capacity in cancer control by training new investigators, engaging established investigators in cancer-focused implementation science, and contributing to the Implementation Science Consortium in Cancer.

METHODS

Three cores serve as OPTICC's foundation. The Administrative Core plans coordinates and evaluates the Center's activities and leads its capacity-building efforts. The Implementation Laboratory Core (I-Lab) coordinates a network of diverse clinical and community sites, wherein studies are conducted to optimize EBI implementation, implement cancer control EBIs, and shape the Center's agenda. The Research Program Core conducts innovative implementation studies, measurement and methods studies, and pilot studies that advance the Center's theme. A three-stage approach to optimizing EBI implementation is taken-(I) identify and prioritize determinants, (II) match strategies, and (III) optimize strategies-that is informed by a transdisciplinary team of experts leveraging multiphase optimization strategies and criteria, user-centered design, and agile science.

DISCUSSION

OPTICC will develop, test, and refine efficient and economical methods for optimizing EBI implementation by building implementation science capacity in cancer researchers through applications with our I-Lab partners. Once refined, OPTICC will disseminate its methods as toolkits accompanied by massive open online courses, and an interactive website, the latter of which seeks to simultaneously accumulate knowledge across OPTICC studies.

Addressing cancer prevention and control in Armenia: tobacco control and mHealth as key strategies

This paper focuses on the particular challenges in cancer prevention and control (CPC) in low- and middle-income countries (LMICs). In particular, this paper extrapolates challenges and opportunities in Armenia, which has the 2nd highest rate of cancer-related deaths in the world, the 11th highest smoking prevalence among men globally, and an evolving health system infrastructure for non-communicable disease (NCD) prevention and control, including CPC. Despite significant progress in enhancing research capacity in Armenia over the past decade, additional efforts are needed, particularly in CPC-related research. Key opportunities are to advance tobacco control and utilization of mHealth. Public health training programs remain insufficient in the area of CPC, and in-country research expertise regarding CPC and related areas (e.g., tobacco control, mHealth, policy) is limited, particularly given the need to address the diverse and complex determinants of onset, prevention, and management of cancer. Moreover, critical gaps in research dissemination and knowledge translation from evidence to policy and practice continue to exist. Thus, public health infrastructure must be enhanced, in-country CPC leaders across various relevant disciplines must be further developed and supported, and medical and public health training must more fully integrate CPC and research dissemination and translation to inform policy and practice.

Revisiting time to translation: implementation of evidence-based practices (EBPs) in cancer control

PURPOSE

Previous studies estimate translation of research evidence into practice takes 17 years. However, this estimate is not specific to cancer control evidence-based practices (EBPs), nor do these studies evaluate variation in the translational process. We examined the translational pathway of cancer control EBPs.

METHODS

We selected five cancer control EBPs where data on uptake were readily available. Years from landmark publication to clinical guideline issuance to implementation, defined as 50% uptake, were measured. The translational pathway for each EBP was mapped and an average total time across EBPs was calculated.

RESULTS

Five cancer control EBPs were included: mammography, clinicians' advice to quit smoking, colorectal cancer screening, HPV co-testing, and HPV vaccination. Time from publication to implementation ranged from 13 to 21 years, averaging 15 years. Time from publication to guideline issuance ranged from 3 to 17 years, and from guideline issuance to implementation, - 4 to 12 years. Clinician's advice to quit smoking, HPV co-testing, and HPV vaccination were most rapidly implemented; colorectal cancer screening and mammography were slowest to implement.

CONCLUSION

The average time to implementation was 15 years for the five EBPs we evaluated, a marginal improvement from prior findings. Although newer EBPs such as HPV vaccination and HPV co-testing were faster to implement than other EBPs, continued efforts in implementation science to speed research to practice are needed.

Changes in cancer incidence and mortality in Australia over the period 1996-2015

OBJECTIVE

A previous Australian study compared the observed numbers of cancer cases and deaths in 2007 with the expected numbers based on 1987 rates. This study examines the impact of cancer rate changes over the 20-year period 1996-2015, for people aged under 75 years.

RESULTS

The overall age-standardised cancer incidence rate increased from 350.7 in 1995 to 364.4 per 100,000 in 2015. Over the period 1996-2015, there were 29,226 (2.0%) more cases (males: 5940, 0.7%; females: 23,286, 3.7%) than expected numbers based on 1995 rates. Smaller numbers of cases were observed compared to those expected for cancers of the lung for males and colorectum, and cancers with unknown primary. Larger numbers of cases were observed compared to those expected for cancers of the prostate, thyroid and female breast. The overall age-standardised cancer mortality rate decreased from 125.6 in 1995 to 84.3 per 100,000 in 2015. During 1996 to 2015 there were 106,903 (- 20.6%) fewer cancer deaths (males: - 69,007, - 22.6%; females: - 37,896, - 17.9%) than expected based on the 1995 mortality rates. Smaller numbers of deaths were observed compared to those expected for cancers of the lung, colorectum and female breast, and more cancer deaths were observed for liver cancer.

Cancer control in Ghana: A narrative review in global context

Globally, cancer is likely to be ranked as the leading cause of death among non-communicable diseases in the 21st century. In Ghana, estimates suggest that the disease is expected to increase continuously. The best way to address the increasing burden is through a comprehensive cancer control program. This paper presents an appraisal of the literature, reports and, studies that seek to highlight strategies for cancer control globally and in Ghana. In consideration of literature, a search of relevant databases (PubMed, Google Scholar, Cochrane Database of Systematic Reviews, Google, International organizations web pages, International reports, Ministry of Health of Ghana reports, and textbooks) was performed. A narrative review of the background information on this subject is provided to inform future research on cancer control. This review was conducted as part of a study to involve community pharmacists in cancer detection and prevention in Ghana.

Promoting evidence-based practices for breast cancer care through web-based collaborative learning

The Knowledge Summaries for Comprehensive Breast Cancer Control (KSBCs) are a series of 14 publications aligned with World Health Organization guidance on evidence-based breast cancer control and accepted frameworks for action. To study utilization of the KSBCs in the development of locally relevant breast cancer control policies and programs in limited resource settings, the National Cancer Institute Center for Global Health, the University of Washington and the Fred Hutchinson Cancer Research Center developed the Project ECHO® for KSBCs (KSBC ECHO). Project ECHO is an online model which employs case-based learning, while promoting multi-directional learning and network-building. The program was evaluated using a pre-post study design to assess if this online collaborative learning platform can be an effective model for dissemination and utilization of the KSBCs to inform breast cancer control programs and policy advocacy in limited resource settings. A total of 28 KSBC ECHO participants (57%) responded to the baseline and endpoint program evaluation surveys. Across all 28 respondents, analysis of the data indicates that knowledge increase was statistically significant overall: average knowledge gain was 0.77, 95% CI [0.44 - 1.08] and p value < 0.0001. A majority of responding team leads reported that the core ECHO components (case/didactic presentations, discussion) contributed to a great extent to strengthening their project proposal/goals. Program evaluation survey responses indicate that utilization of this online platform provided an opportunity for individual knowledge gain, multi-directional information exchange, network-building, and strengthening of the proposed breast cancer control projects based in limited resource settings.

Focal therapy with high-intensity focused ultrasound for the localized prostate cancer for Asian based on the localization with MRI-TRUS fusion image-guided transperineal biopsy and 12-cores transperineal systematic biopsy: prospective analysis of oncological and functional outcomes

BACKGROUND

We evaluated clinical outcomes of region target focal therapy with high-intensity focused ultrasound (HIFU) for the localized prostate cancer (PCa) based on magnetic resonance imaging-based biopsy and systematic prostate biopsy for Asian.

METHODS

We prospectively recruited patients with localized PCa, located their significant tumors using MRI-transrectal ultrasound (TRUS) elastic fusion image-guided transperineal prostate biopsy and 12-cores transperineal systematic biopsy, and focally treated these regions in which the tumors were located in the prostate using HIFU. Patients' functional and oncological outcomes were analyzed prospectively.

RESULTS

We treated 90 men (median age 70 years; median PSA level 7.26 ng/ml). Catheterization was performed within 24 h after the treatment in all patients. Biochemical disease-free rate was 92.2% during 21 months follow-up when use of Phoenix ASTRO definition. In follow-up biopsy, significant cancer was detected in 8.9% of the patients in un-treated areas. Urinary functions, including international prostate symptom score (IPSS) (P < 0.0001), IPSS quality of life (QOL) (P = 0.001), overactive bladder symptom score (OABSS) (P < 0.0001), EPIC urinary domain (P < 0.0001), maximum urinary flow rate (P < 0.0001), and IIEF-5 (P = 0.001), had significantly deteriorated at 1 month after treatment, but improved to preoperative levels at 3 or 6 months. Rates of erectile dysfunction and ejaculation who had the functions were 86% and 70%, respectively, at 12 months after treatment.

CONCLUSIONS

The present treatment for Asian would have similar oncological and functional outcomes to those in previous reports. Further large studies are required to verify oncological and functional outcomes from this treatment for patients with localized PCa.

Understanding Skin Screening Practices Among Children at Elevated Risk for Melanoma to Inform Interventions for Melanoma Prevention and Control

Melanoma is the deadliest form of skin cancer. Screening can aid in early disease detection, when treatment is more effective. Although there are currently no consensus guidelines regarding skin screening for pediatric populations with elevated familial risk for melanoma, at-risk children with the help of their parents and healthcare providers may implement skin self-exams. Healthcare providers may also recommend screening practices for these children. The goal of the current study was to describe current screening behaviors and provider recommendation for screening among children of melanoma survivors. Parents of children with a family history of melanoma completed a questionnaire that included items on children's screening frequency, thoroughness, and who performed the screening. Seventy-four percent of parents reported that their children (mean age = 9.0 years, SD = 4.8) had engaged in parent-assisted skin self-exams (SSEs) in the past 6 months. Only 12% of parents reported that children received SSEs once per month (the recommended frequency for adult melanoma survivors). In open-ended responses, parents reported that healthcare providers had provided recommendations around how to conduct SSEs, but most parents did not report receiving information on recommended SSE frequency. Twenty-six percent of parents (n = 18) reported that children had received a skin exam by a healthcare provider in the past 6 months. The majority of children with a family history of melanoma are reportedly engaging in skin exams despite the lack of guidelines on screening in this population. Future melanoma preventive interventions should consider providing families guidance about implementing screening with their children.

An Asian Body to Tackle Cancers in Asia - The Asian National Cancer Centers Alliance

The socioeconomic burden of cancer is growing rapidly in the Asian region, with a concentrated burden on low- and middle- income countries. The residents of this region, representing almost 60% of the global population, demonstrate an eclectic and complex nature, with huge disparities in ethnicity, sociocultural practices among others. The Asian National Cancer Centers Alliance (ANCCA) was established in 2005 by heads of several national cancer centers (NCCs) in the region to address common issues and concerns among Asian countries. During the first 13 years of ANCCA’s existence, the participating NCCs’ senior managers paved the way toward collaboration through transparent sharing of key facts and activities. Concrete achievements of the Alliance include the Asia Tobacco-Free Declaration, the establishment of the ANCCA Constitution in 2014 as well as the creation of an official website more recently. In November 2019, the most active ANCCA members (China, India, Indonesia, Japan, Korea, Mongolia, Singapore, Thailand, and Vietnam) strengthened the bonds of the entity with the clear aim to halt the increase in cancer and mortality rates in Asian countries by 2030. New opportunities including accelerated cooperation between members as well as collaboration with external and multidisciplinary stakeholders at local, regional and international levels are an essential step to most effectively tackle cancers in Asia.

Training Future Leaders: Experience from China-ASEAN Cancer Control Training Program

Cancer care professionals are pivotal in translating the knowledge into action in the continuum of cancer control process. Unfortunately, in China and the Association of South-east Asian Nations (ASEAN), limited training opportunities are available for health professionals in the area of cancer prevention and control. Therefore, the Cancer Hospital, Chinese Academy of Medical Sciences (CICAMS), and the International Agency for Research on Cancer (IARC) collaboratively designed and held the China-ASEAN Cancer Control and Prevention Training Program to provide continuing education opportunities for cancer professionals from China and ASEAN countries. The aim of this article is to report on the effectiveness and quality of the program and share our experience. A total of 36 participants from 12 countries completed the whole course including 1-month online learning and 1-week face-to-face workshop and cancer control facility tour in October 2017. After completion of the program, all participants were invited to fill out a questionnaire and to provide their comments on the training course. Out of 36 participants, 33 completed the evaluation form and they rated the training course highly in terms of satisfaction, value, and likelihood of recommending it to other colleagues. Additionally, all participants provided very detailed and practical comments on the course. Such an intensive, short-term, and comprehensive training program is expected to help participants establish a broader view of cancer prevention and control within the wider health services and be involved in national cancer control programs in a more efficient way. This training course could serve as a model for other institutes dedicated to nurturing future leaders in cancer control.

Putting Evidence Academies into action: Prostate cancer, nutrition, and tobacco control science

A well-documented challenge in moving public health research into practice is the extended time it takes to implement findings in clinical practice and communities. The Evidence Academy model (Rohweder et al., 2016), developed and first used in North Carolina, is a pragmatic, action-oriented model that aims to shorten this timeline by communicating cutting-edge findings directly to those who can use them and convening individuals working in a single topic area to network and plan activities for the future. The University of Pennsylvania Collaborating Center of the Cancer Prevention and Control Research Network (CPCRN) held three conferences based on the Evidence Academy model: one about prostate cancer in 2015, a second on food access and obesity prevention in 2017, and a third about tobacco control science in 2018. A diverse planning committee of stakeholders helped shape the content, focus,and format of each conference. Local and national experts presented findings to regional audiences of researchers, practitioners, government leaders, and community members. Each Evidence Academy included collaborators and speakers from other Prevention Research Centers (PRCs) and CPCRN network sites. Evaluations and outcomes indicated that the events were successful in achieving their goals and fostered ongoing relationships among attendees. This paper illustrates how the Evidence Academy model was used in a different region and describes lessons learned and follow-up activities that were initiated via the Evidence Academy and with input from participants. Lessons learned may be helpful in developing and evaluating future adaptations of the Evidence Academy model and/or the effectiveness of its components.

Food Label Literacy and Use among US Adults Diagnosed with Cancer: Results from a National Representative Study

For those diagnosed with cancer, lifestyle factors including diet can be more important than ever. However, lack of nutrition-related knowledge can pose a significant barrier to healthy eating. Food labels guide consumers in selecting appropriate portion sizes-that is, caloric content-and ensuring adequate intake of nutrients. Data from the 2013-2014 HINTS were used to examine (a) differences in food label use and food label literacy between respondents ever had a cancer diagnosis and those never had a diagnosis; (b) sociodemographic correlates and health-related correlates of food label use and literacy, in a context of cancer diagnosis; and (c) potential association between food label use/literacy and each of two dietary choices, eating vegetables and fruits and limiting intake of sugary drinks, again, in a context of cancer diagnosis. Data was analyzed via SPSS version 24.0, and cross tabulations using Pearson's Chi-square test and logistic regressions. Income, gender and non-participation in support groups were associated with food label literacy (p<.05). Confidence to take care of self was associated with food label use (p<.05). Relationships were observed between using food labels and curtailing soda intake (b = -.368, p<.05), eating relatively more fruits (b = .558, p<.05), and eating relatively more vegetables (b = .558, p<.05). The overall models predicting consumption of soda [x2 (2) = 13.70, p = .001, Nagelkerke R-square = .059], of fruits [x2 (2) = 33.87, p < .001, Nagelkerke R-square = .136], and of vegetables [x2 (2) = 36.08, p < .001, Nagelkerke R-square = .144] was statistically significant. Implications for research and practice can be found in results linking food label use to better quality diets. They include the usefulness of nutrition education interventions targeting lower-income men with cancer diagnoses; one lesson should be the use of food labels.

[Clinical target volume : Principles and limits]

BACKGROUND

The clinical target volume (CTV) is regarded fundamental for radiotherapy planning by the International Commission on Radiation Units and Measurements (ICRU).

OBJECTIVES

The aim of this article is to give an overview on the basics and problems of defining the CTV for radiotherapy planning.

MATERIALS AND METHODS

After briefly defining CTV, a short description of the process to homogenize CTV in intraindividual comparisons is given, where special attention is paid to radiological requirements. This information is summarized in a number of tables.

RESULTS

CTV is the most complex volume among the target volumes that have been defined by the ICRU. A survey of the determinants of the definition of CTV is given.

CONCLUSIONS

This overview on the basic rules of how to define CTVs can help to increase the understanding of the radiological requirements for optimum imaging to support radiotherapy planning regardless of the specialty of the physician.

Sociodemographic correlates of cancer fatalism and the moderating role of religiosity: Results from a nationally-representative survey

In general, it has been found that cancer fatalism is negatively associated with important cancer prevention and control behaviors, whereas religiosity is positively associated with these behaviors. Yet, the notion that religiosity gives rise to fatalistic beliefs that may discourage health behaviors is deeply ingrained in the public health literature. In addition, racial/ethnic group membership is associated with higher reports of cancer fatalism, though this association may be confounded by socioeconomic status (SES). A better understanding of the relationships between racial/ethnic group membership, SES, and religiosity may contribute to the development of effective interventions to address cancer fatalism and improve health behaviors. In this study, we examined associations between racial/ethnic group membership, SES, and cancer fatalism as the outcome. In addition, we tested whether religiosity (as measured by religious service attendance) moderated these relationships.

Collaborating to conquer cancer: the role of partnerships in comprehensive cancer control

Comprehensive cancer control celebrated its twentieth anniversary in 2018. A dedicated group of national partners formed the Comprehensive Cancer Control National Partnership (CCCNP) at the same time that CDC's National Comprehensive Cancer Control Program was formed. The CCCNP has supported the development and growth of comprehensive cancer control from its inception. The CCCNP mirrors how coalitions function at the state, tribe, territory, and Pacific Island Jurisdiction level. We provide a national example of how 19 leading cancer organizations work together with a unified vision to support cancer control efforts in the United States (U.S.). What follows is an overview of the CCCNP, its vision, mission, and structure and a description of how this partnership has evolved over the past 20 years. The importance of collaboration is highlighted. Two states, South Dakota and Kansas, provide examples of how working with partners through the cancer coalition has advanced their state's cancer control agenda. Closing thoughts on the future work of the CCCNP are provided, including a continued focus on supporting health equity; better engagement and support of CCC coalition leaders; and informing efforts to develop a national cancer control plan for the United States.

Comprehensive cancer control in the U.S.: summarizing twenty years of progress and looking ahead

In order to celebrate the accomplishments of the Centers for Disease Control and Prevention's (CDC) National Comprehensive Cancer Control Program (NCCCP), the Comprehensive Cancer Control National Partners (CCCNP) developed this Special Issue on Cancer Causes and Control. This, the third Special Issue on Comprehensive Cancer Control (CCC), is a reflection of 20 years of building successful partnerships to prevent and control cancer; planning and implementing strategic cancer control; collaborating to address national cancer prevention and control priorities; evaluating efforts; sharing successes; and, in later years, serving as a model for global cancer control planning and implementation. The CDC currently supports cancer control planning and implementation in all 50 states, the District of Columbia, eight tribes or tribal organizations, and seven Pacific Island Jurisdictions and U.S. territories through the NCCCP. CCC is an approach that brings together multi-sector partners to address the cancer burden in a community collectively by leveraging existing resources and identifying and addressing cancer related issues and needs. The Comprehensive Cancer Control National Partnership (CCCNP), a partnership of national organizations, has been committed to supporting comprehensive cancer control efforts since 1999. We summarize the efforts described in this Special Issue. We also describe opportunities and critical elements to continue the momentum for comprehensive cancer control well into the future.

Ovarian Cancer Knowledge in Women and Providers Following Education with Inside Knowledge Campaign Materials

Because no effective methods for preventing or screening for ovarian cancer exist, symptom recognition is integral to its early detection. The Centers for Disease Control and Prevention's Inside Knowledge: Get the Facts about Gynecologic Cancer campaign was developed to raise awareness and educate women and providers about risk factors, symptoms, recommended screening, and prevention strategies for the five main gynecologic cancers, including ovarian cancer. Inside Knowledge campaign materials were utilized by CDC's National Comprehensive Cancer Control Program grantees to educate women and providers about gynecologic cancer from 2014 to 2015. Grantees recruited participants and held educational sessions using Inside Knowledge materials. Questionnaires were given before and after the sessions to assess changes in awareness, confidence, and behavioral intentions around gynecologic cancer information and analyzed in 2016. This analysis focused on an assessment of changes related to ovarian cancer information. Participants' knowledge increased after educational sessions. Among women, there were increases in correctly identifying that the Papanicolaou (Pap) test does not screen for ovarian cancer (89.2%) and that genetic testing is available (77.9%). There was a lower increase in knowledge that HPV is not a cause of ovarian cancer (56.4%). Providers and women reported significant increases in their confidence in their ability to talk to each other about gynecologic cancer post-session. Ovarian cancer awareness, confidence, and related behaviors increased in participants exposed to Inside Knowledge materials. Using these materials to increase knowledge could lead to more empowered patients, better provider-patient communications, and improved care for gynecologic cancers, including ovarian cancer.

Skin cancer interventions across the cancer control continuum: Review of technology, environment, and theory

The National Cancer Institute's Skin Cancer Intervention across the Cancer Control Continuum model was developed to summarize research and identify gaps concerning skin cancer interventions. We conducted a mapping review to characterize whether behavioral interventions addressing skin cancer prevention and control from 2000 to 2015 included (1) technology, (2) environmental manipulations (policy and/or built environment), and (3) a theoretical basis. We included 86 studies with a randomized controlled or quasi-experimental design that targeted behavioral intervention in skin cancer for children and/or adults; seven of these were dissemination or implementation studies. Of the interventions described in the remaining 79 articles, 57 promoted only prevention behaviors (e.g., ultraviolet radiation protection), five promoted only detection (e.g., skin examinations), 10 promoted both prevention and detection, and seven focused on survivorship. Of the 79 non-dissemination studies, two-thirds used some type of technology (n=52; 65.8%). Technology specific to skin cancer was infrequently used: UVR photography was used in 15.2% of studies (n=12), reflectance spectroscopy was used in 12.7% (n=10), and dermatoscopes (n=1) and dosimeters (n=2) were each used in less than 3%. Ten studies (12.7%) targeted the built environment. Fifty-two (65.8%) of the studies included theory-based interventions. The most common theories were Social Cognitive Theory (n=20; 25.3%), Health Belief Model (n=17; 21.5%), and the Theory of Planned Behavior/Reasoned Action (n=12; 15.2%). Results suggest that skin cancer specific technology and environmental manipulations are underutilized in skin cancer behavioral interventions. We discuss implications of these results for researchers developing skin cancer behavioral interventions.
