State of the Science of Scale-Up of Cancer Prevention and Early Detection Interventions in Low- and Middle-Income Countries: A Scoping Review. JCO Glob Oncol 2024; 10:e2300238. [PMID: 38237096 PMCID: PMC10805431 DOI: 10.1200/go.23.00238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 08/22/2023] [Accepted: 10/18/2023] [Indexed: 01/23/2024] Open
Abstract
PURPOSE Cancer deaths in low- and middle-income countries (LMICs) will nearly double by 2040. Available evidence-based interventions (EBIs) for cancer prevention and early detection can reduce cancer-related mortality, yet there is a lack of evidence on effectively scaling these EBIs in LMIC settings. METHODS We conducted a scoping review to identify published literature from six databases between 2012 and 2022 that described efforts for scaling cancer prevention and early detection EBIs in LMICs. Included studies met one of two definitions of scale-up: (1) deliberate efforts to increase the impact of effective intervention to benefit more people or (2) an intervention shown to be efficacious on a small scale expanded under real-world conditions to reach a greater proportion of eligible population. Study characteristics, including EBIs, implementation strategies, and outcomes used, were summarized using frameworks from the field of implementation science. RESULTS This search yielded 3,076 abstracts, with 24 studies eligible for inclusion. Included studies focused on a number of cancer sites including cervical (67%), breast (13%), breast and cervical (13%), liver (4%), and colon (4%). Commonly reported scale-up strategies included developing stakeholder inter-relationships, training and education, and changing infrastructure. Barriers to scale-up were reported at individual, health facility, and community levels. Few studies reported applying conceptual frameworks to guide strategy selection and evaluation. CONCLUSION Although there were relatively few published reports, this scoping review offers insight into the approaches used by LMICs to scale up cancer EBIs, including common strategies and barriers. More importantly, it illustrates the urgent need to fill gaps in research to guide best practices for bringing the implementation of cancer EBIs to scale in LMICs.

Abstract
This short review summarizes two studies that explore the association between coffee consumption, breast cancer, and mortality. The researchers found possible protective effects of coffee consumption and no association between coffee and increased risk of breast cancer. Nurses can help women who consume coffee to understand the current research regarding the relationship between coffee consumption, breast cancer risk, and mortality. Nurses can recommend referral to registered dietitians for comprehensive counseling on diet and cancer. Nurses can collaborate with interdisciplinary teams to help facilitate research regarding the association between coffee and breast cancer.

Effectiveness of Digital Health on the Quality of Life of Long-Term Breast Cancer Survivors: A Systematic Review. Semin Oncol Nurs 2023; 39:151418. [PMID: 37045645 DOI: 10.1016/j.soncn.2023.151418] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 03/02/2023] [Accepted: 03/08/2023] [Indexed: 04/14/2023]
Abstract
OBJECTIVES To identify, critically appraise, and synthesize the available evidence on the effectiveness of digital health interventions to improve the quality of life or any of its four dimensions (physical, psychological, social, and spiritual) in women survivors of breast cancer who are in the extended or permanent survival stage. DATA SOURCES Systematic review-Four databases were searched: PubMed, CINAHL, PsycINFO, and Web of Science. CONCLUSION The clinical evidence shows a positive relationship or association between eHealth use and improved quality of life in breast cancer survivors at extended or permanent survival stage. However, the findings point to a deficit in the assessment of the social and spiritual domains that play a fundamental role in the quality of life of survivors. IMPLICATION FOR NURSING PRACTICE The findings found reflect implications of great value for nursing practice because these professionals are the main users of digital health tools to provide them to patients. Using these digital tools contributes to improving evidence-based practice and providing greater efficiency and effectiveness in the care of long-term cancer survivors.

Abstract
Background Breast cancer (BC) is the most common cancer in women globally. The North Africa and Middle East (NAME) region is coping hard with the burden of BC. We aimed to present the latest epidemiology of BC and its risk factors in this region. Methods We retrieved the data on BC burden and risk factors from the Global Burden of Disease Study 2019 to describe BC status in the 21 countries of the NAME region from 1990 to 2019. We explored BC incidence, prevalence, deaths, disability-adjusted life years (DALYs), and attributable burden to seven risk factors of female BC, namely, alcohol use, diet high in red meat, low physical activity, smoking, secondhand smoke, high body mass index, and high fasting plasma glucose. Decomposition analysis on BC incidence trend was done to find out the contributing factors to this cancer's growth. Results In 2019, there were 835,576 (95% uncertainty interval: 741,968 to 944,851) female and 10,938 (9,030 to 13,256) male prevalent cases of BC in the NAME region. This number leads to 35,405 (30,676 to 40,571) deaths among female patients and 809 (654 to 1,002) deaths in male patients this year. BC was responsible for 1,222,835 (1,053,073 to 1,411,009) DALYs among female patients in 2019, with a greater proportion (94.9%) of burden in years of life lost (YLLs). The major contributor to female BC incidence increase in the past three decades was found to be increase in age-specific incidence rates of BC (227.5%), compared to population growth (73.8%) and aging (81.8%). The behavioral risk factors were responsible for majority of attributable female BC burden (DALYs: 106,026 [66,614 to 144,247]). High fasting plasma glucose was found to be the risk factor with the largest effect (DALYs: 84,912 [17,377 to 192,838]) on female BC burden. Conclusion The increasing incidence and burden of BC in the NAME region is remarkable, especially when considering limited resources in the developing countries of this region. Proper policies like expanding screening programs and careful resource management are needed to effectively manage BC burden.

Abstract
Rapidly proliferating high-quality evidence supports daily decision-making in clinical practice. Continuing professional medical education links this evidence to practicing clinicians who are strongly motivated to improve the quality of their care by using the latest information. Approaches to professional education vary, and their effects depend on specific scenarios. This narrative review summarizes the main approaches for professional medical education that facilitate the mobilization of evidence for clinicians. It includes traditional learning (passive and active dissemination of educational materials, lectures, and mass media dissemination), constructivist learning (engaging in local consensus processes and education outreach visits, interfacing with local opinion leaders, conducting patient-mediated interventions, employing audit and feedback processes, and utilizing clinical decision-supporting systems), and blended learning approaches (the integration of in-person or online passive learning with active and creative learning by the learners). An optimized selection from these approaches is challenging but critical to clinicians and healthcare systems.

Abstract
INTRODUCTION Immigrant and forcibly displaced women and girls are disproportionately impacted by the harmful health consequences of intimate partner violence (IPV) in the USA. Economic and Social Empowerment (EA$E), a women's protection and empowerment intervention, has shown promising reductions in IPV and gender inequities among forcibly displaced populations (FDPs) in low-income and middle-income countries. However, research on the integration of gender equity interventions into economic empowerment programming for FDPs within the USA is lacking. Additionally, there is growing interest in integrating gender equity programmes among US-based refugee resettlement organisations, including the International Rescue Committee (IRC). We describe our study protocol for examining the feasibility, acceptability and appropriateness of EA$E for use with US-based FDPs, and recommendations for adaptation. METHODS AND ANALYSIS This is a convergent parallel study to guide the adaptation of EA$E for use with US-based FDPs. Mixed methods (quantitative and qualitative) will be used for the adaptation research. Quantitative data will consist of brief surveys, and qualitative data will consist of focus group discussions (FGDs). Our research will be guided by the 'administration' phase of the ADAPT-ITT framework, which entails pretesting the intervention with the new target audience and implementation context to examine acceptability, appropriateness and feasibility to receive feedback to inform modifications of the original intervention. This is done via theatre testing, an innovative approach to pretesting that allows the new target audience to experience the intervention and provide feedback. We will conduct FGDs with IRC staff (n=4, total of 24 participants) and refugee clients (n=8, total of 48 participants, women and men, French and English speaking). ETHICS AND DISSEMINATION The study has received approval from the George Mason University Human Subjects Committee (#1686712-7) and IRC (via reliance agreement). Results will be made available to refugee resettlement organisations, policymakers, funders and other researchers. This study has been registered in Open Science Framework (https://doi.org/10.17605/OSF.IO/SZDVY).

Multi-pilot implementation experiences of patient-centered pathology reports: lessons learned for the advancement of patient-centered tools for cancer decision-making. Cancer Causes Control 2023; 34:399-406.

Abstract
PURPOSE New federal legislation in the United States grants patients expanded access to their medical records, making it critical that medical records information is understandable to patients. Provision of informational summaries significantly increase patient perceptions of patient-centered care and reduce feelings of uncertainty, yet their use for cancer pathology is limited. METHODS Our team developed and piloted patient-centered versions of pathology reports (PCPRs) for four cancer organ sites: prostate, bladder, breast, and colorectal polyp. The objective of this analysis was to identify common barriers and facilitators to support dissemination of PCPRs in care delivery settings. We analyzed quantitative and qualitative data from pilot PCPR implementations, guided by the RE-AIM framework to explore constructs of reach, effectiveness, adoption, implementation, and maintenance. RESULTS We present two case studies of PCPR implementation - breast cancer and colorectal polyps-that showcase diverse workflows for pathology reporting. Cross-pilot learnings emphasize the potential for PCPRs to improve patient satisfaction, knowledge, quality of shared decision-making activities, yet several barriers to dissemination exist. CONCLUSION While there is promise in expanding patient-centered cancer communication tools, more work is needed to expand the technological capacity for PCPRs and connect PCPRs to opportunities to reduce costs, improve quality, and reduce waste in care delivery systems.

Abstract
PURPOSE In Tanzania, high breast cancer mortality can be attributed to delays in diagnosis and treatment initiation. We adapted the cascade analysis method to depict sequential steps along the breast cancer care pathway in a tertiary hospital in Mwanza, to identify where correction of loss to attrition would have the biggest impact on improving outcomes. METHODS This prospective cohort included adult women presenting with breast concerns between February 2020 and January 2022. Five cascade steps beginning with patients' initial clinical breast assessment (CBA) through cancer treatment were identified: (1) CBA, (2) ordering diagnostic test(s), (3) completion of diagnostic test(s), (4) receipt of final diagnosis, and (5) initiating cancer treatment. RESULTS Overall, 721 eligible women with a median age of 42.8 years (IQR, 32.5-55.0) were included. Median time from presentation to treatment initiation was 35 days (IQR, 20-63). For step 1, 39.1% (n = 282) of patients were diagnosed with a benign concern and removed from the cascade. Completion rates for steps 2-4 were 95.0%, 90.2%, and 91.0, respectively. There were 156 (45.6%) patients diagnosed with breast cancer, and for step 5, 71.2% of patients initiated cancer treatment. In steps 2, 3, 4, and 5, there was a loss of 22, 41, 34, and 45 patients, respectively. If loss was eliminated at steps 2, 3, 4, or 5, an additional 6, 12, 11, or 45 patients, respectively, would have completed the pathway. CONCLUSION Initiating cancer treatment was identified as the step with the biggest loss and, if remedied, would have the biggest impact on improving breast cancer outcomes at Bugando Medical Centre. These results will inform future programs focused on reducing overall loss in the system and supporting patients with breast cancer.

Abstract
AIM To synthesize the current evidence of the usefulness of radiomics in PET/CT image analysis in local and locally advanced breast cancer. Also, to evaluate the methodological quality of the radiomic studies published. METHODS Systematic review of articles in different databases until 2021 using the terms "PET", "radiomics", "texture", "breast". Only articles with human data and that included a PET image were included. Studies with simulated data and with less than 20 patients were excluded. Were extracted sample size, radiotracer used, imaging technique, and radiomics characteristics from each article. The methodological quality of the studies was determined using the QUADAS-2 tool. RESULTS 18 articles were selected. The retrospective design was the most used. The most studied radiomic characteristic was SUVmax. Several radiomic parameters were correlated with tumor characterization, and tumor heterogeneity proved useful for predicting disease course and response to treatment. Most articles showed a high risk of bias, mainly from the patient selection. CONCLUSIONS A high probability of bias was observed in most of the published articles. Radiomics is a developing field and more studies are needed to demonstrate its usefulness in routine clinical practice. The QUADAS-2 tool allows critical assessment of the methodological quality of the available evidence. Despite its limitations, radiomics is shown to be an instrument that can help to achieve personalized oncologic management of breast cancer.

Abstract
This narrative review summarizes epidemiological studies on breast cancer and prostate cancer with an overview of their global incidence distribution to investigate the relationship between these diseases and diet. The biological properties, mechanisms of action, and available data supporting the potential role of isoflavones in the prevention of breast cancer and prostate cancer are discussed. Studies evaluating the effects of isoflavones in tissue cultures of normal and malignant breast and prostate cells, as well as the current body of research regarding the effects of isoflavones attained through multiple modifications of cellular molecular signaling pathways and control of oxidative stress, are summarized. Furthermore, this review compiles literature sources reporting on the following: (1) levels of estrogen in breast and prostate tissue; (2) levels of isoflavones in the normal and malignant tissue of these organs in European and Asian populations; (3) average concentrations of isoflavones in the secretion of these organs (milk and semen). Finally, particular emphasis is placed on studies investigating the effect of isoflavones on tissues via estrogen receptors (ER).

Abstract
The Peace of Mind Program is an evidence-based intervention to improve mammography appointment adherence in underserved women. The aim of this study was to assess effectiveness of the intervention and implementation of the intervention in safety net clinics. The intervention was implemented through a non-randomized stepped wedge cluster hybrid study design with 19 Federally Qualified Health Centers and charity care clinics within the Greater Houston area. A multivariable generalized estimating equation logistic regression was conducted to examine mammography appointment adherence. A survey assessing Consolidated Framework for Implementation Research constructs was also conducted with clinic staff prior to adoption and eight weeks post implementation. One-sided t-tests were conducted to analyze mean score changes between the surveys. A total of 4402 women (baseline period = 2078; intervention period = 2324) were included in the final regression analysis. Women in the intervention period were more likely to attend or reschedule their mammography appointment (OR = 1.30; p < 0.01) than those in the baseline period receiving usual care. Women who completed the intervention were more likely to attend or reschedule their mammography appointment than those who did not complete the intervention (OR = 1.62; p < 0.01). The mammography appointment no-show rates for those in the baseline period, in the intervention period, and who completed the intervention were, respectively, 22%, 19%, and 15%. A total of 15 clinics prior to adoption and eight clinics completed the survey at 8 weeks post implementation A statistically significant mean score decrease was observed in Inner Setting and in two Inner Setting CFIR constructs, Culture-Effort, and Implementation Climate. While the intervention improved mammography appointment adherence, there are opportunities to further integrate Consolidated Framework for Implementation Research constructs. Trial registration: Clinical trials registration number: NCT02296177.

Associations between sociodemographic factors and receiving "ask and advise" services from healthcare providers in India: analysis of the national GATS-2 dataset. BMC Public Health 2022; 22:2115. [PMID: 36401241 PMCID: PMC9673333 DOI: 10.1186/s12889-022-14538-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Accepted: 11/03/2022] [Indexed: 11/19/2022] Open
Abstract
Abstract
Background
India is home to about 12% of the world's tobacco users, with about 1.35 million tobacco-related deaths each year. The morbidity and mortality rates are socially patterned based on gender, rural vs. urban residence, education, and other factors. Following the World Health Organization's guidance, it is critical to offer tobacco users support for cessation as a complement to policy and environmental changes. Such guidance is typically unavailable in low-resource systems, despite the potential for population-level impact. Additionally, service delivery for tobacco control tends to be patterned by sociodemographic factors. To understand current activity in this area, we assessed the percentage of daily tobacco users being asked about tobacco use and advised to quit by a healthcare provider. We also examined social patterning of receipt of services (related to by rural vs. urban residence, age, gender, education, caste, and wealth).
Methods
We analyzed cross-sectional data from India's 2016-2017 Global Adult Tobacco Survey (GATS-2), a nationally representative survey. Among 74,037 respondents, about 25% were daily users of smoked and/or smokeless tobacco. We examined rates of being asked and advised about tobacco use overall and based on rural vs. urban residence, age, gender, education, caste, and wealth. We also conducted multivariate logistic regression to assess the association of demographic and socioeconomic conditions with participants' receipt of “ask and advise” services.
Results
Nationally, among daily tobacco users, we found low rates of individuals reporting being asked about tobacco use or advised to quit by a healthcare provider (22% and 19%, respectively). Being asked and advised about tobacco use was patterned by age, gender, education, caste, and wealth in our final regression model.
Conclusions
This study offers a helpful starting point in identifying opportunities to address a critical service delivery gap in India. Given the existing burden on the public health and health systems, scale-up will require innovative, resource-appropriate solutions. The findings also point to the need to center equity in the design and scale-up of tobacco cessation supports so that marginalized and underserved groups will have equitable access to these critical services.

Abstract
Multi-level organizational stakeholder engagement plays an important role across the research process in a clinical setting. Stakeholders provide organizational specific adaptions in evidence-based interventions to ensure effective adoption, implementation, and sustainability. Stakeholder engagement strategies involve building mutual trust, providing clear communication, and seeking feedback. Using constructs from the Consolidated Framework for Implementation Research and The International Association for Public Participation spectrum, a conceptual framework was created to guide stakeholder engagement in an evidence-based intervention to increase mammography appointment adherence in underserved and low-income women. A document review was used to explore the alignment of the conceptual framework with intervention activities and stakeholder engagement strategies. The results indicate an alignment with the conceptual framework constructs and a real-world application of stakeholder engagement in a mammography evidence-based intervention. The conceptual framework and stakeholder engagement strategies can be applied across a range of community-based cancer programs and interventions, organizations, and clinical settings.

Abstract
In research, anticancer agents, such as thiourea derivative compounds, and metal complexes, such as those complexed with iron (III) metal, are often studied. The metal complexes are presumably more active than thiourea derivatives as free ligands; some negative effects may be reduced. The computational studies used in this study involved molecular docking with AutoDock and molecular dynamics (MD) simulations using Desmond to evaluate the stability of the interactions. The docking and MD analysis results showed that compounds 2 and 6 had stable interactions with NUDIX hydrolase type 5 (NUDT5)—one of the therapeutic targets for breast cancer—where they had the lowest root mean square deviation (RMSD) and root mean square fluctuation (RMSF) values compared to the other compounds. Together, these compounds are anti-breast cancer drug candidates.

Abstract
Breast cancer (BC) is a highly metastatic multifactorial disease with various histological and molecular subtypes. Due to recent advancements, the mortality rate in BC has improved over the past five decades. Detection and treatment of many cancers are now possible due to the application of nanomedicine in clinical practice. Nanomedicine products such as Doxil® and Abraxane® have already been extensively used for BC adjuvant therapy with favorable clinical outcomes. However, these products were designed initially for generic anticancer purposes and not specifically for BC treatment. With a better understanding of the molecular biology of BC, several novel and promising nanotherapeutic strategies and devices have been developed in recent years. In this context, multi-functionalized nanostructures are becoming potential carriers for enhanced chemotherapy in BC patients. To design these nanostructures, a wide range of materials, such as proteins, lipids, polymers, and hybrid materials, can be used and tailored for specific purposes against BC. Selective targeting of BC cells results in the activation of programmed cell death in BC cells and can be considered a promising strategy for managing triple-negative BC. Currently, conventional BC screening methods such as mammography, digital breast tomosynthesis (DBT), ultrasonography, and magnetic resonance imaging (MRI) are either costly or expose the user to hazardous radiation that could harm them. Therefore, there is a need for such analytical techniques for detecting BC that are highly selective and sensitive, have a very low detection limit, are durable, biocompatible, and reproducible. In detecting BC biomarkers, nanostructures are used alone or in conjunction with numerous molecules. This review intends to highlight the recent advances in nanomedicine in BC treatment and diagnosis, emphasizing the targeting of BC cells that overexpress receptors of epidermal growth factors. Researchers may gain insight from these strategies to design and develop more tailored nanomedicine for BC to achieve further improvements in cancer specificity, antitumorigenic effects, anti-metastasis effects, and drug resistance reversal effects.

Abstract
Benefits of physical activity (PA) in breast cancer survivors (BCS) are well established. However, programs to promote PA among BCS tailored to real-world contexts within low- to middle-income countries are limited. Cross-sector co-creation can be key to effective and scalable programs for BCS in these countries. This study aimed to evaluate the networking process to engage multisector stakeholders in the co-creation of a PA program for Colombian BCS called My Body. We employed a mixed-methods design including semistructured interviews, workshops and a social network analysis of centrality measures to assess stakeholders' engagement, resources and skills enabling the collaborative work, challenges, outcomes and lessons learned. The descriptive analysis and the centrality measures of the network revealed that 19 cross-sector stakeholders engaged in the My Body collaborative network. Through ongoing communication and cooperation, My Body built relationships between the academic lead institutions (local and international), and local and national public, private and academic institutions working in public health, sports and recreation, social sciences and engineering fields. The outcomes included the co-creation of the community-based PA program for BCS, its implementation through cross-sector synergies, increased relationships and communications among stakeholders, and successful dissemination of evidence and project results to the collaboration partners and other relevant stakeholders and community members. The mixed-methods assessment enabled understanding of ways to advance cross-sector co-creation of health promotion programs. The findings can help to enable continued development of sustainable cross-sector co-creation processes aimed at advancing PA promotion.

Abstract
Simple Summary Previous research describes the issues AYA cancer patients may face when it comes to maintaining social relationships after their diagnosis. Related issues included mutual misconceptions and a lack of understanding of the impact of cancer. The Dutch AYA ‘Young & Cancer’ Care Network co-created the mobile application ‘AYA Match’ to provide support on this matter. Co-creation, in which the target population is directly involved, appears to be an effective way to establish an intervention that applies to their needs. The aim of this study was to describe the cocreational process, characteristics of AYA Match users and their expectations of the app. The application could be useful for a wider audience in the future, such as older cancer patients or individuals dealing with other diseases. Abstract Adolescent and young adult (AYA) cancer patients report a need for support to stay in contact with loved ones after diagnosis. In response to this the Dutch AYA ‘Young & Cancer’ Care Network co-created the mobile application ‘AYA Match’. This study describes the cocreational process, the characteristics of the users and their expectations regarding the app. 121 AYA cancer patients and 37 loved ones completed a questionnaire. 68.6% of the loved ones reported ‘staying in contact’ and ‘finding out about the needs and wishes of ‘their AYA’ during this time’ as the main reasons for downloading the application. 41.1% of the AYA cancer patients expected the app to help them communicate to their loved ones what they do or don’t want and need. 60% of the loved ones indicated that they would like to use the application to offer help to ‘their AYA’ with their daily tasks. Patients and their loved ones have similar expectations when it comes to ‘normalizing’ contact, increasing empathy and mutual understanding about needs and emotions. The AYA Match app could be an adequate answer to the issues experienced regarding contact, support and mutual understanding.

Abstract
Breast cancer has become a real public health problem in Cameroon, particularly in rural areas due to late diagnosis, resulting partly from the absence of national screening programs. This work is aimed at assessing breast cancer awareness in the North Region of Cameroon. Participants were selected in six health centers surrounding the rural area of Garoua, North Region, Cameroon, and administered a questionnaire aimed at assessing their awareness about breast cancer risk factors and screening. Out of the 475 women (including 37 medical personnel) interviewed, 45.5% attended at least secondary school; 91.3% were aware of the disease with the main sources of information from those around them (64.8%), media (46.5%), and health professionals in health facilities (42.7%). 23.3% had misconceptions and myth-based ideas on the origin of the disease. Ignorance was the main reason preventing the performance of breast self-examination, and the high cost prevents individuals from going for mammography. The highest awareness rate was observed in employed women with higher level of education. Our study highlights the need to raise awareness among the populations in North Region, Cameroon, about the risk factors and clinical signs of breast cancer and the importance of screening practice for early diagnosis of breast cancer.

Abstract
Introduction Decisions regarding the geographical placement of healthcare services require consideration of trade-offs between equity and efficiency, but few empirical assessments are available. We applied a novel geospatial framework to study these trade-offs in four African countries. Methods Geolocation data on population density (a surrogate for efficiency), health centres and cancer referral centres in Kenya, Malawi, Tanzania and Rwanda were obtained from online databases. Travel time to the closest facility (a surrogate for equity) was estimated with 1 km resolution using the Access Mod 5 least cost distance algorithm. We studied associations between district-level average population density and travel time to closest facility for each country using Pearson’s correlation, and spatial autocorrelation using the Global Moran’s I statistic. Geographical clusters of districts with inefficient resource allocation were identified using the bivariate local indicator of spatial autocorrelation. Results Population density was inversely associated with travel time for all countries and levels of the health system (Pearson’s correlation range, health centres: −0.89 to −0.71; cancer referral centres: −0.92 to −0.43), favouring efficiency. For health centres, negative spatial autocorrelation (geographical clustering of dissimilar values of population density and travel time) was weaker in Rwanda (−0.310) and Tanzania (−0.292), countries with explicit policies supporting equitable access to rural healthcare, relative to Kenya (−0.579) and Malawi (−0.543). Stronger spatial autocorrelation was observed for cancer referral centres (Rwanda: −0.341; Tanzania: −0.259; Kenya: −0.595; Malawi: −0.666). Significant geographical clusters of sparsely populated districts with long travel times to care were identified across countries. Conclusion Negative spatial correlations suggested that the geographical distribution of health services favoured efficiency over equity, but spatial autocorrelation measures revealed more equitable geographical distribution of facilities in certain countries. These findings suggest that even when prioritising efficiency, thoughtful decisions regarding geographical allocation could increase equitable physical access to services.

Abstract
Background In response to the increasing burden of cancer in Tanzania, the Ministry of Health, Community Development, Gender, Elderly and Children launched National Cancer Treatment Guidelines (TNCTG) in February 2020. The guidelines aimed to improve and standardize oncology care in the country. At Ocean Road Cancer Institute (ORCI), we developed a theory‐informed implementation strategy to promote guideline‐concordant care. As part of the situation analysis for implementation strategy development, we conducted focus group discussions to evaluate clinical systems and contextual factors that influence guideline‐based practice prior to the launch of the TNCTG. Materials and Methods In June 2019, three focus group discussions were conducted with a total of 21 oncology clinicians at ORCI, stratified by profession. A discussion guide was used to stimulate dialogue about facilitators and barriers to delivery of guideline‐concordant care. Discussions were audio recorded, transcribed, translated, and analyzed using thematic framework analysis. Results Participants identified factors both within the inner context of ORCI clinical systems and outside of ORCI. Themes within the clinical systems included capacity and infrastructure, information technology, communication, efficiency, and quality of services provided. Contextual factors external to ORCI included interinstitutional coordination, oncology capacity in peripheral hospitals, public awareness and beliefs, and financial barriers. Participants provided pragmatic suggestions for strengthening cancer care delivery in Tanzania. Conclusion Our results highlight several barriers and facilitators within and outside of the clinical systems at ORCI that may affect uptake of the TNCTG. Our findings were used to inform a broader guideline implementation strategy, in an effort to improve uptake of the TNCTGs at ORCI. Implications for Practice This study provides an assessment of cancer care delivery systems in a low resource setting from the unique perspectives of local multidisciplinary oncology clinicians. Situational analysis of contextual factors that are likely to influence guideline implementation outcomes is the first step of developing an implementation strategy for cancer treatment guidelines. Many of the barriers identified in this study represent actionable targets that will inform the next phases of our implementation strategy for guideline‐concordant cancer care in Tanzania and comparable settings. Guidelines to improve and standardize oncology care in Tanzania were developed in 2020. This study utilized focus group discussions to assess the barriers and facilitators to guideline implementation at Ocean Road Cancer Institute.

Abstract
BACKGROUND Implementation of evidence-based, resource-appropriate guidelines for breast cancer control should be preceded by a baseline assessment or situational analysis to assess breast health infrastructure, workforce capacity, patient pathways, existing practices, accessibility, and costs. METHODS To support the assessment of breast health care systems within the broader context in which they exist, the Breast Health Global Initiative (BHGI) developed, tested, and refined a set of situational analysis tools with which to guide the assessment of breast health care capacity, identify the relative strengths and weaknesses of the health system, and support stakeholders in prioritizing actionable items to advance breast cancer care using evidence-based strategies tailored to their setting. The tools address 6 domains of breast health care delivery: 1) breast cancer early detection practices; 2) breast cancer awareness programs; 3) the availability of breast cancer surgery; 4) the availability of pathology; 5) the availability of radiotherapy, and 6) the availability of systemic therapy services. The current study also describes the more comprehensive International Atomic Energy Agency Programme of Action for Cancer Therapy (PACT) integrated missions for PACT (imPACT) review. RESULTS As of 2020, 5 formal BHGI situational analyses have been performed in India, Brazil, Panama, Tanzania, and Uganda. As of August 2019, a total of 100 imPACT reviews have been conducted in 91 countries. These assessments can contribute to more informed policymaking. CONCLUSIONS Situational analyses are a prerequisite for the development of resource-appropriate strategies with which to advance breast cancer control in any setting and should assess services across the entire breast health care continuum as well as the broader structural, sociocultural, personal, and financial contexts within which they operate.

Breast cancer treatment: A phased approach to implementation. Cancer 2021; 126 Suppl 10:2365-2378.

Abstract
Optimal treatment outcomes for breast cancer are dependent on a timely diagnosis followed by an organized, multidisciplinary approach to care. However, in many low- and middle-income countries, effective care management pathways can be difficult to follow because of financial constraints, a lack of resources, an insufficiently trained workforce, and/or poor infrastructure. On the basis of prior work by the Breast Health Global Initiative, this article proposes a phased implementation strategy for developing sustainable approaches to enhancing patient care in limited-resource settings by creating roadmaps that are individualized and adapted to the baseline environment. This strategy proposes that, after a situational analysis, implementation phases begin with bolstering palliative care capacity, especially in settings where a late-stage diagnosis is common. This is followed by strengthening the patient pathway, with consideration given to a dynamic balance between centralization of services into centers of excellence to achieve better quality and decentralization of services to increase patient access. The use of resource checklists ensures that comprehensive therapy or palliative care can be delivered safely and effectively. Episodic or continuous monitoring with established process and quality metrics facilitates ongoing assessment, which should drive continual process improvements. A series of case studies provides a snapshot of country experiences with enhancing patient care, including the implementation of national cancer control plans in Kenya, palliative care in Romania, the introduction of a 1-stop clinic for diagnosis in Brazil, the surgical management of breast cancer in India, and the establishment of a women's cancer center in Ghana.

Implementation of an integrated framework for a breast cancer screening and navigation program for women from underresourced communities. Cancer 2021; 126 Suppl 10:2481-2493. [PMID: 32348565 DOI: 10.1002/cncr.32843] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2020] [Accepted: 02/06/2020] [Indexed: 01/31/2023]
Abstract
BACKGROUND Trends in breast cancer mortality in the United States are decreasing, but racial disparities persist. Using an implementation science framework to inform evidence-based breast cancer screening and navigation within federally qualified health centers (FQHCs) with community stakeholders can mitigate barriers to screening. METHODS Using an integrated theoretical framework of the Practical, Robust Implementation and Sustainability Model and the Social Ecological Model, the University of Illinois Cancer Center and Mile Square Health Centers (MSHC) FQHC developed a breast cancer screening and navigation program, known as the Mile Square Accessible Mammogram Outreach and Engagement (Mi-MAMO) program, to tackle breast cancer disparities in Chicago among underresourced communities. To increase access to screening, patient navigators conducted community outreach activities. Partnerships were forged with community-based organizations, health care systems, and insurers. Outcomes were monitored with standardized performance measures. RESULTS Between January and December 2017, 103 women received a screening mammogram at MSHC. To increase screening rates, Mi-MAMO was started in August 2017. Between January and December 2018, the number of women who received a screening mammogram increased to 567. From August 2017 to December 2018, 779 women received navigation to screening and/or diagnostic services through the Mi-MAMO program. The majority of women were uninsured (63.9%), and 95.5% were racial/ethnic minorities. Twenty-four percent (n = 185) completed diagnostic services, and 10 women received positive breast cancer diagnoses (mean age, 49.7 years); all successfully navigated to treatment. The Mi-MAMO program is ongoing. CONCLUSIONS Deploying an integrated framework for patient navigation programs can increase breast cancer screening utilization and awareness among underresourced populations at higher risk for breast cancer.

Abstract
BACKGROUND Incidence of breast cancer continues to rise in low- and middle-income countries, with data from the East African country of Tanzania predicting an 82% increase in breast cancer from 2017 to 2030. We aimed to characterize treatment pathways, receipt of therapies, and identify high-value interventions to increase concordance with international guidelines and avert unnecessary breast cancer deaths. METHODS Primary data were extracted from medical charts of patients presenting to Bugando Medical Center, Tanzania, with breast concerns and suspected to have breast cancer. Clinicopathologic features were summarized with descriptive statistics. A Poisson model was utilized to estimate prevalence ratios for variables predicted to affect receipt of life-saving adjuvant therapies and completion of therapies. International and Tanzanian guidelines were compared to current care patterns in the domains of lymph node evaluation, metastases evaluation, histopathological diagnosis, and receptor testing to yield concordance scores and suggest future areas of focus. RESULTS We identified 164 patients treated for suspected breast cancer from April 2015-January 2019. Women were predominantly post-menopausal (43%) and without documented insurance (70%). Those with a confirmed histopathology diagnosis (69%) were 3 times more likely to receive adjuvant therapy (PrR [95% CI]: 3.0 [1.7-5.4]) and those documented to have insurance were 1.8 times more likely to complete adjuvant therapy (1.8 [1.0-3.2]). Out of 164 patients, 4% (n = 7) received concordant care based on the four evaluated management domains. The first most common reason for non-concordance was lack of hormone receptor testing as 91% (n = 144) of cases did not undergo this testing. The next reason was lack of lymph node evaluation (44% without axillary staging) followed by absence of abdominopelvic imaging in those with symptoms (35%) and lack of histopathological confirmation (31%). CONCLUSIONS Patient-specific clinical data from Tanzania show limitations of current breast cancer management including axillary staging, receipt of formal diagnosis, lack of predictive biomarker testing, and low rates of adjuvant therapy completion. These findings highlight the need to adapt and adopt interventions to increase concordance with guidelines including improving capacity for pathology, developing complete staging pathways, and ensuring completion of prescribed adjuvant therapies.

Abstract
Diagnosing cancer earlier can enable timely treatment and optimize outcomes. Worldwide, national cancer control plans increasingly encompass early diagnosis programs for symptomatic patients, commonly comprising awareness campaigns to encourage prompt help-seeking for possible cancer symptoms and health system policies to support prompt diagnostic assessment and access to treatment. By their nature, early diagnosis programs involve complex public health interventions aiming to address unmet health needs by acting on patient, clinical, and system factors. However, there is uncertainty regarding how to optimize the design and evaluation of such interventions. We propose that decisions about early diagnosis programs should consider four interrelated components: first, the conduct of a needs assessment (based on cancer-site-specific statistics) to identify the cancers that may benefit most from early diagnosis in the target population; second, the consideration of symptom epidemiology to inform prioritization within an intervention; third, the identification of factors influencing prompt help-seeking at individual and system level to support the design and evaluation of interventions; and finally, the evaluation of factors influencing the health systems' capacity to promptly assess patients. This conceptual framework can be used by public health researchers and policy makers to identify the greatest evidence gaps and guide the design and evaluation of local early diagnosis programs as part of broader cancer control strategies.

Understanding women's perspectives on breast cancer is essential for cancer control: knowledge, risk awareness, and care-seeking in Mwanza, Tanzania. BMC Public Health 2020; 20:930. [PMID: 32539723 PMCID: PMC7296642 DOI: 10.1186/s12889-020-09010-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2019] [Accepted: 05/28/2020] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Breast Cancer is the most common cancer in women worldwide. Since 2008, Mwanza, Tanzania, has worked to provide comprehensive cancer services through its Zonal consultant hospital. New national guidelines focused on clinical breast exam requires that women be aware of and seek care for breast concerns. Therefore, this study aims to understand breast cancer awareness in Mwanza and describe women-level barriers, care-seeking behavior, and perspectives on breast cancer. METHODS A community-based survey was administered to conveniently sampled women aged 30 and older to assess women's perspectives on breast cancer and care-seeking behavior. RESULTS Among 1129 women with a median age of 37 (IQR: 31-44) years, 73% have heard of cancer and 10% have received breast health education. Women self-evaluated their knowledge of breast cancer (from 1-none to 10-extremely knowledgeable) with a median response of 3 (IQR: 1-4). Only 14% felt they knew any signs or symptoms of breast cancer. Encouragingly, 56% of women were fairly-to-very confident they would notice changes in their breasts, with 24% of women practicing self-breast examination and 21% reporting they had received a past breast exam. Overall, 74% said they would be somewhat-to-very likely to seek care if they noticed breast changes, with 96% noting severity of symptoms as a motivator. However, fear of losing a breast (40%) and fear of a poor diagnosis (38%) were most frequent barriers to care seeking. In assessing knowledge of risk factors, about 50% of women did not know any risk factors for breast cancer whereas 42% of women believed long term contraceptive use a risk factor. However, 37% and 35% of women did not think that family history or being older were risk factors, respectively. CONCLUSIONS The success of efforts to improve early diagnosis in a setting without population-based screening depends on women being aware of breast cancer signs and symptoms, risks, and ultimately seeking care for breast concerns. Fortunately, most women said they would seek care if they noticed a change in their breasts, but the low levels of cancer knowledge, symptoms, and common risk factors highlight the need for targeted community education and awareness campaigns.

Abstract
BACKGROUND The Breast Health Global Initiative (BHGI) established a series of resource-stratified, evidence-based guidelines to address breast cancer control in the context of available resources. Here, the authors describe methodologies and health system prerequisites to support the translation and implementation of these guidelines into practice. METHODS In October 2018, the BHGI convened the Sixth Global Summit on Improving Breast Healthcare Through Resource-Stratified Phased Implementation. The purpose of the summit was to define a stepwise methodology (phased implementation) for guiding the translation of resource-appropriate breast cancer control guidelines into real-world practice. Three expert consensus panels developed stepwise, resource-appropriate recommendations for implementing these guidelines in low-income and middle-income countries as well as underserved communities in high-income countries. Each panel focused on 1 of 3 specific aspects of breast cancer care: 1) early detection, 2) treatment, and 3) health system strengthening. RESULTS Key findings from the summit and subsequent article preparation included the identification of phased-implementation prerequisites that were explored during consensus debates. These core issues and concepts are key components for implementing breast health care that consider real-world resource constraints. Communication and engagement across all levels of care is vital to any effectively operating health care system, including effective communication with ministries of health and of finance, to demonstrate needs, outcomes, and cost benefits. CONCLUSIONS Underserved communities at all economic levels require effective strategies to deploy scarce resources to ensure access to timely, effective, and affordable health care. Systematically strategic approaches translating guidelines into practice are needed to build health system capacity to meet the current and anticipated global breast cancer burden.
