Health system barriers and enablers to early access to breast cancer screening, detection, and diagnosis: a global analysis applied to the MENA region

Global, regional, and national burden of female cancers in women of child-bearing age, 1990-2021: analysis of data from the global burden of disease study 2021

Background

The global status of women's health is underestimated, particularly the burden on women of child-bearing age (WCBA). We aim to investigate the pattern and trend of female cancers among WCBA from 1990 to 2021.

Methods

We retrieved data from the Global Burden of Disease Study (GBD) 2021 on the incidence and disability-adjusted life-years (DALYs) of four major female cancers (breast, cervical, uterine, and ovarian cancer) among WCBA (15-49 years) in 204 countries and territories from 1990 to 2021. Estimated annual percentage changes (EAPC) in the age-standardised incidence and DALY rates of female cancers, by age and socio-demographic index (SDI), were calculated to quantify the temporal trends. Spearman correlation analysis was used to examine the correlation between age-standardised rates and SDI.

Findings

In 2021, an estimated 1,013,475 new cases of overall female cancers were reported globally, with a significant increase in age-standardised incidence rate (EAPC 0.16%), and a decrease in age-standardised DALY rate (-0.73%) from 1990 to 2021. Annual increase trends of age-standardised incidence rate were observed in all cancers, except for that in cervical cancer. Contrary, the age-standardised DALY rate decreased in all cancers. Breast and cervical cancers were prevalent among WCBA worldwide, followed by ovarian and uterine cancers, with regional disparities in the burden of four female cancers. In addition, the age-standardised incidence rates of breast, ovarian, and uterine cancers basically showed a consistent upward trend with increasing SDI, while both the age-standardised incidence and DALY rates in cervical cancer exhibited downward trends with SDI. Age-specific rates of female cancers increased with age in 2021, with the most significant changes observed in younger age groups, except for uterine cancer.

Interpretation

The rising global incidence of female cancers, coupled with regional variations in DALYs, underscores the urgent need for innovative prevention and healthcare strategies to mitigate the burden among WCBA worldwide.

Global burden and attributable risk factors of breast cancer in young women: historical trends from 1990 to 2019 and forecasts to 2030 by sociodemographic index regions and countries

Background

Breast cancer in young women (BCY) is much less common but has significant health sequelae and societal costs. We aimed to evaluate the global and regional burden of breast cancer in women aged 15-39 years from 1990 to 2019.

Methods

We collected detailed data on breast cancer from the Global Burden of Disease Study 2019 (GBD 2019) Data Resources. The age-standardised incidence rate (ASIR), age-standardised mortality rate (ASMR), age-standardised disability-adjusted life years rate (ASDR), and estimated annual percentage change (EAPC) were used to assess the disease burden of BCY. The Bayesian Age-Period-Cohort model was used to forecast disease burden from 2020 to 2030.

Results

From 1990 to 2019, significant increases in ASIR were found for BCY (EAPC = 0.59, 95% confidence interval (CI) = 0.5 to 0.68), whereas decreases in ASMR (EAPC = -0.41, 95% CI = -0.53 to -0.3) and ASDR (EAPC = -0.35, 95% CI = -0.46 to -0.24). Across countries with varying sociodemographic indexes (SDI), all regions showed an upward trend in BCY morbidity, except for countries with a high SDI. While mortality and DALYs rates have decreased in countries with high, high-middle, and middle SDI, they have increased in countries with low-middle and low SDI. Countries with lower SDIs are projected to bear the greatest burden of BCY over the next decade, including both low and low-middle categories. Alcohol use was the main risk factor attributed to BCY deaths in most countries, while exposure to second hand smoke was the predominant risk factor for BCY deaths in middle and low-middle SDI countries.

Conclusions

The burden of breast cancer in young women is on the rise worldwide, and there are significant regional differences. Countries with a low-middle or low SDI face even more challenges, as they experienced a more significant and increasing BCY burden than countries with higher SDIs.

Challenges and Opportunities in Breast Cancer Care in Low-Resourced Countries, Jordan as An Example

Jordan is a relatively small country with a rapidly growing population and a challenged economy. Breast cancer is the most diagnosed cancer among women worldwide and also in Jordan. Though the age-standardized rate (ASR) of breast cancer incidence is still lower than that in Western societies, the number of newly diagnosed cases continues to increase, involving younger women, and new cases are usually detected at more advanced stages. Improvements in breast cancer care across the health care continuum, including early detection, prevention, treatment, and survivorship and palliative care, have become very visible, but may not match the magnitude of the problem. More organized, goal-oriented work is urgently needed to downstage the disease and improve awareness of, access to, and participation in early detection programs. The cost of recently introduced anti-cancer therapies poses a great challenge, but the impact of these therapies on treatment outcomes, including overall survival, is becoming very noticeable. Though the concept of a multidisciplinary approach to breast cancer treatment is often used at most health care facilities, its implementation in real practice varies significantly. The availability of breast reconstruction procedures, survivorship programs, germline genetic testing, counselling, and palliative care is improving, but these are not widely practiced. In this manuscript, we review the status of breast cancer in Jordan and highlight some of the existing challenges and opportunities.

Burden of breast cancer and attributable risk factors in the North Africa and Middle East region, 1990-2019: a systematic analysis for the Global Burden of Disease Study 2019

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.

Care coordination across healthcare systems: development of a research agenda, implications for practice, and recommendations for policy based on a modified Delphi panel

OBJECTIVE

For large, integrated healthcare delivery systems, coordinating patient care across delivery systems with providers external to the system presents challenges. We explored the domains and requirements for care coordination by professionals across healthcare systems and developed an agenda for research, practice and policy.

DESIGN

The modified Delphi approach convened a 2-day stakeholder panel with moderated virtual discussions, preceded and followed by online surveys.

SETTING

The work addresses care coordination across healthcare systems. We introduced common care scenarios and differentiated recommendations for a large (main) healthcare organisation and external healthcare professionals that contribute additional care.

PARTICIPANTS

The panel composition included health service providers, decision makers, patients and care community, and researchers. Discussions were informed by a rapid review of tested approaches to fostering collaboration, facilitating care coordination and improving communication across healthcare systems.

OUTCOME MEASURES

The study planned to formulate a research agenda, implications for practice and recommendations for policy.

RESULTS

For research recommendations, we found consensus for developing measures of shared care, exploring healthcare professionals' needs in different care scenarios and evaluating patient experiences. Agreed practice recommendations included educating external professionals about issues specific to the patients in the main healthcare system, educating professionals within the main healthcare system about the roles and responsibilities of all involved parties, and helping patients better understand the pros and cons of within-system and out-of-system care. Policy recommendations included supporting time for professionals with high overlap in patients to engage regularly and sustaining support for care coordination for high-need patients.

CONCLUSIONS

Recommendations from the stakeholder panel created an agenda to foster further research, practice and policy innovations in cross-system care coordination.

Insurance-based disparities in breast cancer treatment pathways in a universal healthcare system: a qualitative study

BACKGROUND

The influence of healthcare system factors on treatment pathways for breast cancer has been studied extensively in lower-middle-income countries (LMICs), but in upper-middle-income countries (UMICs), this area is understudied. This article focuses on the experiences of breast cancer patients in Türkiye, a UMIC with a universal healthcare system. It explores variations in treatment pathways based on the type of health insurance provider (private or state).

METHODS

The study uses an exploratory qualitative method based on in-depth interviews with 12 breast cancer patients. The inclusion criteria were Turkish nationality, female gender, and having received treatment from a private hospital within one year of the interview. A purposeful sampling strategy was employed to recruit patients who had either social health insurance only or who had private health insurance in addition to their social health insurance. A two-stage thematic analysis of the interview data was conducted. First, we examined whether the type of insurance provider makes a difference in treatment pathways; we then identified healthcare system factors that explain these differences.

RESULTS

The study revealed two distinct pathways to treatment. These differ in terms of financial protection, service coverage, and patients' sense of equity. Patients with private insurance reported easy access to timely and comprehensive treatment. Those without, however, had to navigate complicated routes to treatment; they generally had to resort to seeking treatment from more than one hospital. We found two healthcare system factors that explained the differences: a failure to fully enforce the mandates of the state's social health insurance in the private hospital sector and growing reliance on private insurance to gain access to essential services.

CONCLUSIONS

Based on data from the Turkish case, we conclude that healthcare system factors are indeed influential in shaping treatment pathways for breast cancer in UMICs with universal healthcare. These factors include a failure to fully enforce the mandates of the state's social health insurance programme in the private hospital sector and a growing reliance on private insurance to gain access to essential services. We note that this contrasts dramatically with the situation in LMICs, where the main factors are low-quality care and shortages of medical staff, medicines, and technologies.

Factors associated with the uptake of clinical breast examination among women of reproductive age in Lesotho: analysis of a national survey

BACKGROUND

In low-resource settings with weak health systems, the WHO recommends clinical breast examination (CBE) as the most cost-effective breast screening modality for women. Evidence shows that biennial CBE leads to significant downstaging of breast cancer in all women. Breast cancer is the second most common cancer among women in Lesotho with a weaker healthcare system and a low breast cancer screening rate. This study investigated the prevalence and factors associated with the uptake of CBE among women of reproductive age in Lesotho.

METHODS

This study used cross-sectional data from the 2014 Lesotho Demographic and Health Survey. A sample of 6584 reproductive-age women was included in this study. We conducted both descriptive and multivariable logistic regression analyses. The study results were presented in frequencies, percentages, and adjusted odds ratios (aOR) with their corresponding confidence intervals (CIs).

RESULTS

The prevalence of CBE uptake was 9.73% (95% CI: 8.91, 10.61). Women who were covered by health insurance (aOR = 2.31, 95% CI [1.37, 3.88]), those who were pregnant (aOR = 2.34, 95% CI [1.64, 3.35]), those who had one to three children (aOR = 1.81, 95% CI [1.29,2.52]), and women who frequently read newspapers or magazines (aOR = 1.33, 95% CI [1.02,1.72]) were more likely to undergo CBE than their counterparts. Women who were aware of breast cancer (aOR = 2.54, 95% CI [1.63,3.97]), those who have ever had breast self-examination (BSE) within the last 12 months prior to the study (aOR = 5.30, 95% CI [4.35,6.46]), and those who visited the health facility in the last 12 months prior to the study (aOR = 1.57, 95% CI [1.27,1.95]) were also more likely to undergo CBE than their counterparts. Women residing in the Qacha's-nek region (aOR = 0.42, 95% CI [0.26,0.67]) were less likely to undergo CBE than those in the Botha-bothe region.

CONCLUSION

The study found a low prevalence of CBE uptake among reproductive-age women in Lesotho. Factors associated with CBE uptake include health insurance coverage, being pregnant, those who had one to three children, exposure to media, breast cancer awareness, ever had BSE, and those who visited a health facility. To increase CBE uptake, these factors should be considered when designing cancer screening interventions and policies in order to help reduce the burden of breast cancer in Lesotho.

Effectiveness of breast cancer screening interventions in improving screening rates and preventive activities in Muslim refugee and immigrant women: A systematic review and meta-analysis

PURPOSE

To systematically assess the effectiveness of breast cancer (BC) interventions in improving breast self-examination (BSE), clinical breast examination (CBE), mammogram screening rates, and preventive activities in Muslim refugee and immigrant women.

DESIGN

Guided by the Health Belief Model, a mixed method systematic review and meta-analysis was performed using a sequential design.

METHODS

This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement (PRISMA), the Critical Appraisal Skill Program Checklists, and the Joanna Briggs Institute (JBI) methodology for systematic review and meta-analysis. A systematic search of English-language peer-reviewed articles was undertaken in multiple health and social sciences databases from January 1, 2015, to March 31, 2022. Randomized clinical trials and quasi-experimental studies focused on the uptake of BSE, CBE, and mammograms were selected.

RESULTS

Fourteen articles were included in the review. Most of the studies relied on quasi-experimental designs and were carried out in the United States of America. The qualitative analysis of BC screening interventions generated three themes: (1) education, (2) access-focused, and (3) cultural and faith-based. The meta-analysis included three randomized control trials and two quasi-experimental studies. The meta-analysis demonstrates the effectiveness of community-led cultural and faith-based interventions in facilitating the completion of CBE and mammography screening. Education on BC and patient navigator interventions are more effectively used in conjunction than standalone interventions, yet community-based cultural and faith-based interventions are the most effective.

CONCLUSION

This systematic and meta-analysis review provides evidence on the effectiveness of access-focused and cultural and faith-based interventions in improving BC screening in Muslim refugee and immigrant women. Future research should focus on designing and measuring the effectiveness of cultural and faith-based interventions to increase Muslim refugee and immigrant women's BC screening knowledge and practices.

CLINICAL RELEVANCE

This systematic and meta-analysis review demonstrates the need to explore Muslim refugee and immigrant women's cultural contexts for developing culturally sensitive BC screening interventions. Knowledge and practice of BC and religiosity intersect with financial, geographic, and linguistic barriers to decrease participation in screening and preventive activities in Muslim refugee and immigrant women.

Health system barriers influencing timely breast cancer diagnosis and treatment among women in low and middle-income Asian countries: evidence from a mixed-methods systematic review

BACKGROUND

Globally, breast cancer is the most common cancer type and the leading cause of cancer mortality among women in developing countries. A high prevalence of late breast cancer diagnosis and treatment has been reported predominantly in Low- and Middle-Income Countries (LMICs), including those in Asia. Thus, this study utilized a mixed-methods systematic review to synthesize the health system barriers influencing timely breast cancer diagnosis and treatment among women in Asian countries.

METHODS

We systematically searched five electronic databases for studies published in English from 2012 to 2022 on health system barriers that influence timely breast cancer diagnosis and treatment among women in Asian countries. The review was conducted per the methodology for systematic reviews and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, while health system barriers were extracted and classified based on the World Health Organization (WHO)'s Health Systems Framework. The mixed-methods appraisal tool was used to assess the methodological quality of the included studies.

RESULTS

Twenty-six studies were included in this review. Fifteen studies were quantitative, nine studies were qualitative, and two studies used a mixed-methods approach. These studies were conducted across ten countries in Asia. This review identified health systems barriers that influence timely breast cancer diagnosis and treatment. The factors were categorized under the following: (1) delivery of health services (2) health workforce (3) financing for health (4) health information system and (5) essential medicines and technology. Delivery of health care (low quality of health care) was the most occurring barrier followed by the health workforce (unavailability of physicians), whilst health information systems were identified as the least barrier.

CONCLUSION

This study concluded that health system factors such as geographical accessibility to treatment, misdiagnosis, and long waiting times at health facilities were major barriers to early breast cancer diagnosis and treatment among Asian women in LMICs. Eliminating these barriers will require deliberate health system strengthening, such as improving training for the health workforce and establishing more healthcare facilities.

Factors associated with mammography screening among Reunionese women : a cross-sectional study

OBJECTIVE

To explore the factors associated with the uptake of mammography screening in Reunionese women aged 50-65 years.

METHODS

This study included all women aged 50 to 65 years participating in a population-based cross-sectional study "FOSFORE". Participants were recruited between March and June 2017 using two sampling frames. The first frame consisted of households with a landline telephone, with or without a mobile line, by first randomly generating a telephone number and then randomly selecting an individual from among all eligible women in the household. The second sampling frame was constituted of women with an exclusive mobile line, who were selected directly if they met the eligibility criteria. Data were weighted for age and socio-professional status to ensure representativeness at the Reunion Island level. Weighted logistic regression was used to calculate odds ratios while adjusting for confounders.

RESULTS

417 women were included in the study; 63.8% were up to date with guidelines on mammography screening and 36.2% were not up to date. Four factors were significantly associated with mammography screening, with an adjusted odds ratio of 2.92 (95% CI 1.51-5.61) for not having an Active Solidarity Income, 1.98 (95% CI 1.22-3.23) for having a regular gynecological follow-up by a physician, 6.53 (95% CI 3.23-13.21) for performing a Pap smear test in the past two years, and 2.07 (95% CI 1.21-3.52) for having an adequate literacy level (HLQ3).

CONCLUSION

The findings of this study suggest that higher socio-economic status is an indicator of participation in mammography screening in La Réunion, and future educational and intervention programs should target women in deprived areas.

Religion and cancer prevention: study protocol for a systematic review

INTRODUCTION

Several studies explored a relationship between religiousness and the utilisation of cancer screenings, as religious people may obtain an increased social network or could have certain personality traits that enhance screening use. To the best of our knowledge, there is no systematic review that sums up the evidence gained from research on that relationship. Thus, our review aims to appraise the findings of observational studies regarding that relationship. Its findings may be useful in addressing specific target groups to increase ineffectively the low cancer screening rates.

METHODS AND ANALYSIS

Employing a predefined search algorithm, three online databases (CINAHL, PsycInfo and PubMed) will be searched. In addition, the bibliographies of the studies included in our review will be searched through manually and independently by two reviewers. We are looking for observational studies (both cross-sectional and longitudinal) which examine the association between religion and cancer screening utilisation. However, studies regarding specific samples (as ethnic minorities or religious sects) will be excluded. We expect that the studies examine various dimensions of religion, such as religious attendance or religious intensity. We will extract data that describe methodology, sample characteristics and the findings concerning our object of investigation. Moreover, a quality assessment will be performed. Two reviewers will independently select the studies, extract the data and assess the studies' quality. Disagreements will be dissolved by discussion or by inclusion of a third party. The findings will be presented narratively in text and tables. If possible, a meta-analysis will be carried out.

ETHICS AND DISSEMINATION

As no primary data are collected, the approval from an ethics committee is not required. Our review will be published in a peer-reviewed, scientific journal.

Regional and social inequalities in mammography and Papanicolaou tests in Brazilian state capitals in 2019: a cross-sectional study

OBJECTIVE

To assess regional and social inequalities in mammography and Papanicolaou tests.

METHODS

This was a cross-sectional study with data from the 2019 Chronic Disease Risk and Protective Factors Surveillance Telephone Survey (Vigitel). The outcome variables were mammography and cytopathology test. The exposure variables were race/skin color, schooling and region of residence in Brazil. Absolute inequality measurements were presented using the slope index of inequality (SII) and equiplots.

RESULTS

23,339 women were included in this study. Having a mammography was 5.2 percentage points higher in women with higher levels of education, while having a cytopathology test was 5.3 percentage points lower in women of Black race/skin color.Having mammography and cytopathology tests was 3.9 and 11.2 percentage points higher, respectively, in the Southern region.

CONCLUSION

Social and regional inequalities persist in Brazil and affect mainly women of Black race/skin color, with low education levels and living in the Northeast region of the country.

National Cancer Information System Within the Framework of Health Insurance in Colombia: A Real-World Data Approach to Evaluate Access to Cancer Care

PURPOSE

The National Cancer Information System (NCIS) has been operating since 2014, including information reported by health care insurers and providers on people with cancer diagnosed and treated within the Colombian health system. Its main purpose is to identify barriers to an effective access to cancer diagnosis and treatment across the country. We aimed to describe the methodology, scope and results in terms of access to health services with real-world data provided by the NCIS.

METHODS

Reporting of all cases of cancer by insurers and providers is mandatory by law. Data gathered include demographic and clinical information about new and old cases of cancer who receive health services. Over the years, the reporting process has been automated and it is currently performed in real time. Data quality is ensured through a standardized data-monitoring process. Access to health services is monitored by quality measures defined by consensus.

RESULTS

Since 2015, prevalent cases of invasive cancer have increased from 163,776 to 331,021 in 2020 (increment of 102.12%). Regarding quality measures, the proportion of people staged at diagnosis has increased over the years, especially in breast cancer. Meanwhile, early diagnosis is still concerning for breast and prostate cancer. Time to diagnosis and treatment have not consistently reached the expected goals in breast, cervical, and prostate cancer, whereas they have shown a better level of compliance for stomach and colon and rectum tumors, still not reaching the highest performance.

CONCLUSION

The real-world information approach provided by the NCIS may be complementary for cancer control planning in Colombia, emphasizing better management processes of health insurers and providers by identifying barriers for timely access to health care.

Health system factors that influence diagnostic and treatment intervals in women with breast cancer in sub-Saharan Africa: a systematic review

BACKGROUND

Breast cancer patients in sub-Saharan Africa experience long time intervals between their first presentation to a health care facility and the start of cancer treatment. The role of the health system in the increasing treatment time intervals has not been widely investigated. This review aimed to identify existing information on health system factors that influence diagnostic and treatment intervals in women with breast cancer in sub-Saharan Africa to contribute to the reorientation of health policies in the region.

METHODS

PubMed, ScienceDirect, African Journals Online, Mendeley, ResearchGate and Google Scholar were searched to identify relevant studies published between 2010 and July 2020. We performed a qualitative synthesis in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Related health system factors were extracted and classified according to the World Health Organization's six health system building blocks. The quality of qualitative and quantitative studies was assessed by using the Critical Appraisal Skills Program Quality-Assessment Tool and the National Institute of Health Quality Assessment Tool, respectively. In addition, we used the Confidence in the Evidence from Reviews of Qualitative Research tool to assess the evidence for each qualitative finding.

RESULTS

From 14,184 identified studies, this systematic review included 28 articles. We identified a total of 36 barriers and 8 facilitators that may influence diagnostic and treatment intervals in women with breast cancer. The principal health system factors identified were mainly related to human resources and service delivery, particularly difficulty accessing health care, diagnostic errors, poor management, and treatment cost.

CONCLUSION

The present review shows that diagnostic and treatment intervals among women with breast cancer in sub-Saharan Africa are influenced by many related health system factors. Policy makers in sub-Saharan Africa need to tackle the financial accessibility to breast cancer treatment by adequate universal health coverage policies and reinforce the clinical competencies for health workers to ensure timely diagnosis and appropriate care for women with breast cancer in this region.

Global Perspectives on Palliative Care for Cancer Patients: Not All Countries Are the Same

Abstract

Purpose of the Review

The integration of cancer-related palliative care is essential to holistic, quality cancer care. While some similarities exist between countries, this manuscript will focus on five differences that impact palliative care for cancer patients including the epidemiology of cancer and related symptoms, cancer-specific integration into care, palliative care education, economic development of the country, and cultural and religious differences.

Recent Findings

The epidemiology of cancer varies around the world resulting in variable symptoms and the need for individualized approaches to palliative care. While palliative care is integrated in some countries, it is lacking in over half of the world, and specific integration into cancer care is virtually absent. Education and training are the key to expansion, and yet oncology-focused palliative care education is lacking or is not well-reported in the literature. To complicate this global lens even further are the economic disparities that exist. Low-to-middle-income countries (LMICs) are resource poor and have the fewest resources and least amount of integration, and yet patients with advanced cancer are over-represented in these countries. Essential to cancer-related palliative care is a tailored approach that addresses cultural and religious differences around the globe.

Summary

Palliative care is developing around the globe and yet palliative care specific for cancer patients is in its infancy. Cancer care professionals should (1) understand the epidemiologic differences that exist globally and the impact this has on palliative care, (2) integrate palliative care into the cancer care arena, (3) provide cancer-specific palliative education focused on the cancer trajectory from diagnosis through survivorship and end of life, (4) advocate for LMICs, which suffer from a lack of resources and services, and (5) understand cultural and religious differences that exist to provide holistic and sensitive cancer-related palliative care.

National and Subnational Incidence, Mortality, and Years of Life Lost Due to Breast Cancer in Iran: Trends and Age-Period-Cohort Analysis Since 1990

Breast cancer is the most common cancer among women, causing considerable burden and mortality. Demographic and lifestyle transitions in low and low-middle income countries have given rise to its increased incidence. The successful management of cancer relies on evidence-based policies taking into account national epidemiologic settings. We aimed to report the national and subnational trends of breast cancer incidence, mortality, years of life lost (YLL) and mortality to incidence ratio (MIR) since 1990. As part of the National and Subnational Burden of Diseases project, we estimated incidence, mortality and YLL of breast cancer by sex, age, province, and year using a two-stage spatio-temporal model, based on the primary dataset of national cancer and death registry. MIR was calculated as a quality of care indicator. Age-period-cohort analysis was used to distinguish the effects of these three collinear factors. A significant threefold increase in age-specific incidence at national and subnational levels along with a twofold extension of provincial disparity was observed. Although mortality has slightly decreased since 2000, a positive mortality annual percent change was detected in patients aged 25-34 years, leading to raised YLLs. A significant declining pattern of MIR and lower provincial MIR disparity was observed. We observed a secular increase of breast cancer incidence. Further evaluation of risk factors and developing national screening policies is recommended. A descending pattern of mortality, YLL and MIR at national and subnational levels reflects improved quality of care, even though mortality among younger age groups should be specifically addressed.

Collagen Type X Alpha 1 (COL10A1) Contributes to Cell Proliferation, Migration, and Invasion by Targeting Prolyl 4-Hydroxylase Beta Polypeptide (P4HB) in Breast Cancer

Background

Breast cancer, a common malignant tumor, has been considered as the leading cause of cancer-related death in women. Collagen type X alpha 1 (COL10A1) is overexpressed in breast cancer. The current study was designed to determine the functional involvement and regulatory mechanism of COL10A1 on the growth and metastasis of breast cancer.

Material/Methods

COL10A1 and Prolyl 4-hydroxylase beta polypeptide (P4HB) expressions in normal tissues and tumor tissues of breast cancer patients were obtained from the GEPIA dataset. COL10A1 and P4HB levels in breast cancer cell lines were detected by real-time quantitative polymerase chain reaction (RT-qPCR) and western blot analysis. Furthermore, the interaction between COL10A1 and P4HB was confirmed by co-immunoprecipitation (Co-IP) assay. Cell Counting Kit-8 (CCK-8) and colony formation assay were applied to evaluate cell proliferation and clone-forming abilities of breast cancer cells. In addition, wound healing assay and transwell assay were performed to measure cell migration and invasion capabilities, respectively, in breast cancer.

Results

The GEPIA dataset presented overexpressed COL10A1 and P4HB in tumor tissues of breast cancer patients. COL10A1 and P4HB expression levels were greatly upregulated in breast cancer cell lines. In addition, COL10A1 could directly interact with P4HB. Functionally, overexpressed COL10A1 boosted the proliferation and metastasis of breast cancer cells and silenced COL10A1 impeded the progression of breast cancer. More importantly, knockdown of P4HB weakened the promoting effects of overexpressed COL10A1 on cell proliferation, migration, and invasion in breast cancer.

Conclusions

COL10A1 promotes the malignant progression of breast cancer by upregulating P4HB expression, indicating that COL10A1 functions as an oncogene in breast cancer.

Robust breast cancer detection in mammography and digital breast tomosynthesis using an annotation-efficient deep learning approach

Breast cancer remains a global challenge, causing over 600,000 deaths in 2018 (ref. ¹). To achieve earlier cancer detection, health organizations worldwide recommend screening mammography, which is estimated to decrease breast cancer mortality by 20-40% (refs. ^2,3). Despite the clear value of screening mammography, significant false positive and false negative rates along with non-uniformities in expert reader availability leave opportunities for improving quality and access^4,5. To address these limitations, there has been much recent interest in applying deep learning to mammography^6-18, and these efforts have highlighted two key difficulties: obtaining large amounts of annotated training data and ensuring generalization across populations, acquisition equipment and modalities. Here we present an annotation-efficient deep learning approach that (1) achieves state-of-the-art performance in mammogram classification, (2) successfully extends to digital breast tomosynthesis (DBT; '3D mammography'), (3) detects cancers in clinically negative prior mammograms of patients with cancer, (4) generalizes well to a population with low screening rates and (5) outperforms five out of five full-time breast-imaging specialists with an average increase in sensitivity of 14%. By creating new 'maximum suspicion projection' (MSP) images from DBT data, our progressively trained, multiple-instance learning approach effectively trains on DBT exams using only breast-level labels while maintaining localization-based interpretability. Altogether, our results demonstrate promise towards software that can improve the accuracy of and access to screening mammography worldwide.

Perceived barriers to seeking cancer care in the Gaza Strip: a cross-sectional study

BACKGROUND

Several factors might contribute to the delay to get cancer care including poor cancer awareness and having barriers to seeking help. This study described these barriers in Gaza and their association with recalling and recognizing cancer symptoms and risk factors.

METHODS

A cross-sectional study was conducted in Gaza. Adult visitors (≥18 years) to the largest three governmental hospitals and adolescent students (15-17 years) from ten high schools were recruited. A translated-into-Arabic version of the validated Cancer Awareness Measure (CAM) was used to collect data in face-to-face interviews. It described demographic data, barriers to seek cancer care as well as recall and recognition of cancer symptoms and risk factors. Responses were compared between adults and adolescents as well as males and females.

RESULTS

Of 3033 participants approached, 2886 completed the CAM (response rate= 95.2%). Among them, 1429 (49.5%) were adult (702 females; 49.1%) and 1457 (50.5%) were adolescent (781 females; 53.6%). The mean age± standard deviation (SD) of adult and adolescent participants was 33.7±11.7 years and 16.3±0.8 years, respectively. Emotional barriers were the most common barriers with 'feeling scared' as the most reported barrier (n=1512, 52.4%). Females and adolescents were more likely to report 'feeling scared' as a barrier than males and adults, respectively. Higher recall scores for cancer symptoms were associated with lower likelihood to report 'embarrassment', 'worry about wasting doctor's time' and 'difficulty arranging transport'. This was also seen for recalling risk factors, where 'embarrassment' and all practical barriers showed significant inverse associations with higher scores. In addition, greater recognition scores of cancer risk factors were inversely associated with reporting 'embarrassment' and 'feeling scared'.

CONCLUSIONS

The most commonly perceived barriers to seeking cancer care were 'feeling scared' and 'feeling worried about what the doctor might find', followed by practical and service barriers. Females and adolescents were more likely to report 'fear' as a barrier to seek medical advice. Having a higher recall of cancer symptoms and risk factors was inversely associated with reporting most barriers. To improve patient outcome, early presentation can be facilitated by targeting barriers specific to population groups.

National and Subnational Incidence, Mortality, and Years of Life Lost Due to Breast Cancer in Iran: Trends and Age-Period-Cohort Analysis Since 1990

Breast cancer is the most common cancer among women, causing considerable burden and mortality. Demographic and lifestyle transitions in low and low-middle income countries have given rise to its increased incidence. The successful management of cancer relies on evidence-based policies taking into account national epidemiologic settings. We aimed to report the national and subnational trends of breast cancer incidence, mortality, years of life lost (YLL) and mortality to incidence ratio (MIR) since 1990. As part of the National and Subnational Burden of Diseases project, we estimated incidence, mortality and YLL of breast cancer by sex, age, province, and year using a two-stage spatio-temporal model, based on the primary dataset of national cancer and death registry. MIR was calculated as a quality of care indicator. Age-period-cohort analysis was used to distinguish the effects of these three collinear factors. A significant threefold increase in age-specific incidence at national and subnational levels along with a twofold extension of provincial disparity was observed. Although mortality has slightly decreased since 2000, a positive mortality annual percent change was detected in patients aged 25-34 years, leading to raised YLLs. A significant declining pattern of MIR and lower provincial MIR disparity was observed. We observed a secular increase of breast cancer incidence. Further evaluation of risk factors and developing national screening policies is recommended. A descending pattern of mortality, YLL and MIR at national and subnational levels reflects improved quality of care, even though mortality among younger age groups should be specifically addressed.

Assessing Knowledge and Perceptions of Colorectal Cancer Screening in Armenia

BACKGROUND

Armenia has a high incidence of and mortality from colorectal cancer (CRC). No organized screening programs for CRC exist in Armenia. This study seeks to evaluate knowledge of and attitudes toward CRC and screening programs in Armenia.

METHODS

Adults aged 40-64 y were administered a survey using convenience sampling throughout polyclinics in Yerevan city. Survey questions were based on the Health Belief Model and were translated and modified for local relevance.

RESULTS

A total of 368 surveys were completed. Eighty-four percent had knowledge of CRC, 91% believed that early detection leads to improved outcomes, but only 22% had knowledge of screening. Women were more likely to have knowledge of CRC (odds ratio 2.19, P < 0.05). Although 19% have personally worried about having CRC, only 7% admitted to discussing their worries with a provider and 76% were willing to undergo screening if recommended by their doctor. Seventy-eight percent of respondents would only undergo screening if free or less than ~$20 USD.

CONCLUSIONS

Self-reported knowledge of CRC is high, whereas knowledge of screening remains low in Armenia. There is a willingness to undergo screening if recommended by a health care professional; however, this willingness is cost-sensitive. Interventions aimed at (1) increasing awareness of the disease and screening tests, (2) improving physician counseling, and (3) reducing financial barriers to screening should be considered along with the implementation of a national screening program in Armenia.

Health systems constraints and facilitators of human papillomavirus immunization programmes in sub-Saharan Africa: a systematic review

Given the vast investments made in national immunization programmes (NIPs) and the significance of NIPs to public health, it is important to understand what influences the optimal performance of NIPs. It has been established that well-performing NIPs require enabling health systems. However, systematic evidence on how the performance of health systems impacts on NIPs is lacking, especially from sub-Saharan Africa. We conducted a qualitative systematic review to synthesize the available evidence on health systems constraints and facilitators of NIPs in sub-Saharan Africa, using human papillomavirus immunization programmes as a proxy. Fifty-four articles published between 2008 and 2018 were found to be eligible. Data extraction was guided by an analytical model on the interface between NIPs and health systems. A cross-cutting thematic analysis of the extracted data was performed. This systematic review provides evidence necessary for informing ongoing health systems strengthening initiatives in sub-Saharan Africa. There is evidence to suggest that NIPs in sub-Saharan Africa have surmounted significant health systems constraints and have achieved notable public health success. This success can be attributed to strong political endorsement for vaccines, clear governance structures and effective collaboration with global partners. Despite this, significant health systems constraints persist in service delivery, vaccine communication, community engagement, the capacity of the health workforce and sustainable financing. These constraints could derail further progress if not addressed through health systems strengthening efforts. There is a need to expand the research agenda to include the comprehensive evaluation of health systems constraints and facilitators of NIPs within sub-Saharan Africa.

Adaptation and validation of the Arabic version of self-efficacy scale for mammography. A report on psychometric properties

Objectives:

To culturally adapt and validate a mammography-specific self-efficacy (MSSE) scale into Arabic for the Saudi Arabian context.

Methods:

A methodological study aimed at tool translation and adaptation conducted in primary healthcare centers in As Madinah, Saudi Arabia between March 2016 and May 2016. The MSSE scale was translated and adapted into Arabic using standard procedures. Content and face validity were investigated. Confirmatory factor analysis and reliability analysis were used to determine the scale’s psychometric properties.

Results:

The scale showed a good internal consistency (Cronbach’s alpha=0.88). The confirmatory factor analysis supported the scale’s single-factor structure and the goodness-of-fit indices confirmed the model’s good fit (comparative fit index=0.961, Tucker-Lewis index=0.943, root-mean-square error of approximation=0.076, and standardized root-mean-square residual=0.045). Women who had a mammogram in the last 2 years scored significantly higher on the scale (39±6.2) than women who had never received a mammogram (35.88±7.2; p=0.009).

Conclusion:

The study confirmed that the scale’s Arabic version has good psychometric properties, using reliability analysis, confirmatory factor analysis, and extreme groups validation. The scale is likely to be useful for evaluating interventional studies aimed at improving mammography screening participation rates.

Relationship between Mammographic Density and Age in the United Arab Emirates Population

Objective

Higher breast density is a strong, independent risk factor for breast cancer. Breast density varies by age, ethnicity, and geographic area although dense breast tissue has been associated with younger age and premenopausal status. The relationship between breast density and age in women in the United Arab Emirates (UAE) has not been determined. This study evaluated breast density in the UAE population and its relationship with age.

Methods

Women participating in the national cancer screening program from August 2015 to May 2018 who underwent screening mammography were included. Breast parenchymal density was classified according to the American College of Radiology (ACR) Breast Imaging-Reporting and Data System (BI-RADS) from category a (almost entirely fatty) through d (extremely dense). Subjects were divided into six age groups, and the association between age and breast density was evaluated.

Results

Of the 4911 women included, 1604 (32.7%), 2149 (43.8%), 1055 (21.5%), and 103 (2.1%) were classified as having categories a–d breast density, respectively. A significant negative correlation was observed between age and breast density category (p < 0.001). Women of mean age 44 ± 7 years had the highest breast density, whereas those of mean age 56 ± 14 years had the lowest breast density. Comparisons of Emirati women with Lebanese and Western women showed that breast density was lower in Emirati women than in the other populations.

Conclusions

To our knowledge, this is the first study to evaluate the relationship between mammographic breast density and age in UAE women. As in other populations, age was inversely related to breast density, but the proportion of Emirati women with dense breasts was lower than in other populations. Because this study lacked demographic, clinical, and histopathological data, further evaluation is required.

Time trends in prostate cancer screening in Swiss primary care (2010 to 2017) - A retrospective study

Introduction

Following years of controversy regarding screening for prostate cancer using prostate-specific antigen, evidence evolves towards a more restrained and preference-based use. This study reports the impact of landmark trials and updated recommendations on the incidence rate of prostate cancer screening by Swiss general practitioners.

Methods

We performed a retrospective analysis of primary care data, separated in 3 time periods based on dates of publications of important prostate-specific antigen screening recommendations. 1: 2010-mid 2012 including 2 updates; 2: mid 2012-mid 2014 including a Smarter Medicine recommendation; 3: mid-2014—mid-2017 maintenance period. Period 2 including the Smarter Medicine recommendation was defined as reference period. We further assessed the influence of patient’s age and the number of prostate-specific-antigen (PSA) tests, by the patient and within each time period, on the mean PSA concentration. Uni- and multivariable analyses were used as needed.

Results

36,800 men aged 55 to 75 years were included. 14.6% had ≥ 2 chronic conditions, 11.7% had ≥ 1 prostate-specific antigen test, (mean 2.60 ng/ml [SD 12.3]). 113,921 patient-years were covered. Data derived from 221 general practitioners, 33.5% of GP were women, mean age was 49.4 years (SD 10.0), 67.9% used prostate-specific antigen testing. Adjusted incidence rate-ratio (95%-CI) dropped significantly over time periods: Reference Period 2: incidence rate-ratio 1.00; Period 1: incidence rate-ratio 1.74 (1.59–1.90); Period 3: incidence rate-ratio 0.61 (0.56–0.67). A higher number of chronic conditions and a patient age between 60–69 years were significantly associated with higher screening rate. Increasing numbers of PSA testing per patient, as well as increasing age, were independently and significantly associated with an increase in the PSA value.

Conclusion

Swiss general practitioners adapted screening behavior as early as evidence of a limited health benefit evolved, while using a risk-adapted approach whenever performing multiple testing. Updated recommendations might have helped to maintain this decrease. Further recommendations and campaigns should aimed at older patients with multimorbidity, to sustain a further decline in prostate-specific antigen screening practices.

Perceived Barriers to Mammography Adoption among Women in Iran: A Qualitative Study

Background

Breast cancer is the most commonly diagnosed tumorous cancer and the second leading cause of cancer-related deaths among women worldwide. This study aimed to qualitatively explore the barriers to mammography adoption among Iranian women.

Methods

This study is a qualitative component of a large research project on exploratory sequential mixed method design, utilizing conventional content analysis. In total, 24 participants were selected from among women who had participated in the first phase of the study. Data were collected through in-depth, semi-structured interviews.

Results

Five main themes were extracted, consisting of unawareness of mammography, fear control, priority of mammography needs, inadequate competency of mammography centers, and a sense of losing family support.

Conclusion

Different perceived barriers within various levels (individual, intrapersonal, health systems, and community) play influential roles in women’s decisions to participate in breast cancer screening program, which indicates the cultural aspect of perceived barriers in different communities and countries. The study provides the basis for intervention planning in this regard.
