Guideline implementation for breast healthcare in low- and middle-income countries: early detection resource allocation

Designing a Collaborative Breast Radiology Training Program to Tackle Tanzania's Breast Cancer Crisis

Breast cancer incidence and mortality continue to increase in Africa. In Tanzania, breast cancer is the second leading cause of cancer death for women, and breast cancer incidence and mortality are projected to increase by 80% by 2030. Education gaps among health care workers, delayed presentation, limited screening, and low health literacy all pose significant challenges to providing optimal breast cancer care. Considering these factors, it is imperative to train expert breast radiologists. We present a collaborative breast radiology training program in Tanzania aimed at building local capacity to address national breast cancer challenges. Although cancer control in Africa faces many challenges, developing customized training programs for breast radiology, in conjunction with national cancer programs, may represent a key strategy for addressing breast cancer.

Implementing supplementary breast cancer screening in women with dense breasts: Insights from European radiographers and radiologists

INTRODUCTION

In response to the critical need for enhancing breast cancer screening for women with dense breasts, this study explored the understanding of challenges and requirements for implementing supplementary breast cancer screening for such women among clinical radiographers and radiologists in Europe.

METHOD

Fourteen (14) semi-structured online interviews were conducted with European clinical radiologists (n = 5) and radiographers (n = 9) specializing in breast cancer screening from 8 different countries: Denmark, Finland, Greece, Italy, Malta, the Netherlands, Switzerland, United Kingdom. The interview schedule comprised questions regarding professional background and demographics and 13 key questions divided into six subgroups, namely Supplementary Imaging, Training, Resources and Guidelines, Challenges, Implementing supplementary screening and Women's Perspective. Data analysis followed the six phases of reflexive thematic analysis.

RESULTS

Six significant themes emerged from the data analysis: Understanding and experiences of supplementary imaging for women with dense breasts; Challenges and requirements related to training among clinical radiographers and radiologists; Awareness among radiographers and radiologists of guidelines on imaging women with dense breasts; Challenges to implement supplementary screening; Predictors of Implementing Supplementary screening; Views of radiologists and radiographers on women's perception towards supplementary screening.

CONCLUSION

The interviews with radiographers and radiologists provided valuable insights into the challenges and potential strategies for implementing supplementary breast cancer screening. These challenges included patient and staff related challenges. Implementing multifaceted solutions such as Artificial Intelligence integration, specialized training and resource investment can address these challenges and promote the successful implementation of supplementary screening. Further research and collaboration are needed to refine and implement these strategies effectively.

IMPLICATIONS FOR PRACTICE

This study highlights the urgent need for specialized training programs and dedicated resources to enhance supplementary breast cancer screening for women with dense breasts in Europe. These resources include advanced imaging technologies, such as MRI or ultrasound, and specialized software for image analysis. Moreover, further research is imperative to refine screening protocols and evaluate their efficacy and cost-effectiveness, based on the findings of this study.

Multi-level barriers to early detection of breast cancer among rural midlife women in Tanzania: A qualitative case study

BACKGROUND

Breast cancer is the second most common cause of cancer mortality among women in Tanzania and thus, early detection and treatment methods are central to improving breast cancer outcomes. However, in low- and middle-income countries in Sub-Saharan Africa, the survival rates remains low due to late presentation. Hence, a significant number of deaths could be prevented if barriers and facilitators to early detection are known.

PURPOSE

This qualitative case descriptive study explored the possible barriers to awareness and early breast cancer diagnostic services among midlife women in rural Tanzania.

METHODS

Ten key informant interviews with health systems managers and community health workers and eight focus group discussions with women aged 40-65 years and their spouses were conducted to elicit the study data conducted from July to August 2021.

RESULTS

The data revealed nine themes describing the barriers to early detection methods across five Socio-Ecological levels of influence, namely: 1) limited knowledge and 2) witchcraft beliefs (individual level); 3) limited male support (interpersonal level); 4) age and gender factors and 5) procrastination (community level) 6) limited availability of services 7) emphasis of curative over preventive care (institutional level); 8) poverty/inability to pay and 9) limitations of health insurance (societal/policy level).

CONCLUSIONS

The study findings suggest a need to further the design, implementation and evaluation of evidence-based community breast health awareness and education interventions to promote early detection of breast cancer in Tanzania. Specifically, the study highlights the need to address multiple level determinants of influence in breast cancer control as part of the country's Community Health Strategy.

Improving access to breast cancer screening and treatment in Nigeria: The triple mobile assessment and patient navigation model (NCT05321823): A study protocol

BACKGROUND

In Nigeria, breast cancer incidence is rising, late presentation is common, and outcomes are poor. Patient-related factors such as lack of awareness and misperceptions in addition to health system deficiencies such as lack of a clearly defined framework for breast cancer screening and referral are some of the major drivers of this poor outlook. Guidelines for breast cancer screening in high-income countries have limited applicability in low-middle-income countries, hence the need for innovative, resource-compatible strategies to combat the negative trend. This manuscript presents our study protocol which aims to evaluate the impact of a novel breast cancer early detection program developed to address delayed presentation and lack of access to diagnostic and treatment facilities in South-West Nigeria. This entails the use of mobile technology (innovative handheld iBreast Exam [iBE] device, mobile breast ultrasound, and mobile mammography) and patient navigation as interventions at the community level.

METHODS

The study (ClinicalTrials.gov identifier: NCT05321823) will adopt a randomized two group clinical trial design with one local government area (LGA) serving as an intervention arm and another serving as the control. Both LGAs will receive breast cancer awareness education but only one will receive the interventions. In the intervention arm, asymptomatic (40-70 years) and symptomatic (30-70 years) women will be invited for breast evaluation which will be performed by trained Community Health Nurses using Clinical Breast Exam (CBE), and iBE. Those with positive findings will proceed to imaging using mobile mammography and ultrasound brought to the LGA every month. Symptomatic women with negative findings on CBE and iBE will be scheduled for repeat clinical evaluation on a short-term basis (one month). The Radiologist will obtain core needle biopsies as indicated and transfer them for prompt pathological assessment. Women presenting to the Primary Healthcare Centers in the control LGA will be referred directly to Obafemi Awolowo University Teaching Hospitals Complex as per the current standard of care. Records of all breast cancer cases seen in the two LGAs during the study period will be obtained. The program metrics will include screening participation rate, cancer detection rate, stage at diagnosis, and timeline from detection to initiation of treatment. The stage at diagnosis and timeline from detection to treatment compared between the two LGAs will be used to assess the impact of the intervention. The study is proposed for 2 years; however, a descriptive analysis will be carried out at 1.5 years to evaluate the retention of the study participants.

STUDY SIGNIFICANCE

It is anticipated that this study will provide vital data to support wider breast cancer screening efforts in Nigeria.

Determine knowledge and belief of Somalian young women about breast cancer and breast self-examination with champion health belief model: a cross-sectional study

BACKGROUND

Breast cancer (BC) is an important reason for mortality rates in Somalian women. In Somalia, many women are late in applying to the hospital for the diagnosis of BC. Breast self-examination (BSE) is considered an important early detection method for BC in encouraging women to learn to practice BSE, especially for women in developing countries. This study purposed to determine knowledge, and belief of BC and BSE and BSE practice among women in Mogadishu, Somalia using the champion health belief model (CHBM).

METHODS

This cross-sectional study was conducted on 413 women who were between 18 and 49 years of age. The data were collected by using sociodemographic variables (age, marital status, education level, income status), Champion's Health Belief Model Scale (CHBMS), and an introductory questionnaire with questions about BC and BSE and between October 2020 and January 2021 in Mogadishu, Somalia. Further descriptive statistics, the Mann-Whitney U test, and Kruskal-Wallis analysis test were used to assess data that were not normally distributed.

RESULTS

Average age of participants was 22 ± 11.21 years. Only 35.4% of participants had information about BC, 37.8% had heard about BSE before, 25.2% knew BSE, and only 17.2% had done it. Income status, marital status, and age of first birth family were significantly associated with perceived sensitivity, health motivation, convenience, perceived benefits, and self-efficacy for BSE. Overall, the total scores of CHBMS were significantly higher among those who had heard and knowledge about BSE and practiced clinical breast examination (CBE). For the sub-dimensions of perceived sensitivity, health motivation, perceived benefits, barrier, and self-efficacy BSE with hearing about BSE, practicing BSE, knowing to practice BSE, knowing early detection methods of BC and practice CBE significant differences were observed (P < 0.005).

CONCLUSION

This study showed that BSE practice among Somalian women was very low, and they don't have sufficient knowledge about BSE and BC. Furthermore, this study revealed that many CHBMS significantly related to BSE practice in Somalian women, suggesting that BSE health education programs with CHBMS.

Cancer survival in Thailand from 1997 to 2012: Assessing the impact of universal health coverage

BACKGROUND

In recent decades, many countries worldwide have implemented some form of Universal Health Coverage (UHC). We sought to evaluate incidence and survival trends of breast, cervical, and colorectal cancer before and after the implementation of UHC in Thailand.

METHODS

The age-standardized incidence rate and 1- and 5-year net survival (NS) were calculated for five Thai provinces, namely Bangkok, Chiang Mai, Khon Kaen, Lampang, and Songkhla for breast, cervix, and colorectal cancer in three study periods (1997-2012): before, during, and after the implementation of UHC.

RESULTS

The incidence of breast and colorectal cancer has increased over time, while the incidence of cervical cancer has decreased (17.9-29.9, 9.0-13.6, and 19.6-12.3 per 100,000, respectively). Larger proportion of breast cancer were diagnosed with localized stage after UHC implementation compared to the period prior to UHC (31.5 % vs 19.0 %). Overall, The improvement in survival by cancer site varied in magnitude with a 5-year NS increase from 61.3 % to 75.1 % for breast, 55.4-59.5 % for cervical, and 39.9-47.6 % for colorectal cancer. The amount of increase slightly differed across provinces.

CONCLUSION

Rising incidence for breast and colorectal, and declining cervical cancer may partly be attributable to improved awareness and early detection programs. Additionally, improvement in survival may partly be attributable to increased access to healthcare, availability of treatment, and increased access to cancer screening after UHC was implemented. Thus, continued expansion of UHC package on cancer could potentially contribute to further improvement of cancer control in Thailand.

POLICY SUMMARY

This study provides important evidence on the impact of UHC in cancer burden and survival for breast, cervical, and colorectal cancer in Thailand. This study serves as an example for other countries where UHC has been recently implemented and guide policymakers in allocating resources towards UHC and cancer control programs.

Global guidelines for breast cancer screening: A systematic review

Objectives

Breast cancer screening guidelines could provide valuable tools for clinical decision making by reviewing the available evidence and providing recommendations. Little information is known about how many countries have issued breast cancer screening guidelines and the differences among existing guidelines. We systematically reviewed current guidelines and summarized corresponding recommendations, to provide references for good clinical practice in different countries.

Methods

Systematic searches of MEDLINE, EMBASE, Web of Science, and Scopus from inception to March 27th, 2021 were conducted and supplemented by reviewing the guideline development organizations. The quality of screening guidelines was assessed from six domains of the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) instrument by two appraisers. The basic information and recommendations of the issued guidelines were extracted and summarized.

Results

A total of 23 guidelines issued between 2010 and 2021 in 11 countries or regions were identified for further review. The content and quality varied across the guidelines. The average AGREE Ⅱ scores of the guidelines ranged from 33.3% to 87.5%. The highest domain score was "clarity of presentation" while the domain with the lowest score was "applicability". For average-risk women, most of the guidelines recommended mammographic screening for those aged 40–74 years, specifically, those aged 50–69 years were regarded as the optimal age group for screening. Nine of 23 guidelines recommended against an upper age limit for breast cancer screening. Mammography (MAM) was recommended as the primary screening modality for average-risk women by all included guidelines. Most guidelines suggested annual or biennial mammographic screening. Risk factors of breast cancer identified in the guidelines mainly fell within five categories which could be broadly summarized as the personal history of pre-cancerous lesions and/or breast cancer; the family history of breast cancer; the known genetic predisposition of breast cancer; the history of mantle or chest radiation therapy; and dense breasts. For women at higher risk, there was a consensus among most guidelines that annual MAM or annual magnetic resonance imaging (MRI) should be given, and the screening should begin earlier than the average-risk group.

Conclusions

The majority of 23 included international guidelines were issued by developed countries which contained roughly the same but not identical recommendations on breast cancer screening age, methods, and intervals. Most guidelines recommended annual or biennial mammographic screening between 40 and 74 years for average-risk populations and annual MAM or annual MRI starting from a younger age for high-risk populations. Current guidelines varied in quality and increased efforts are needed to improve the methodological quality of guidance documents. Due to lacking clinical practice guidelines tailored to different economic levels, low- and middle-income countries (LMICs) should apply and implement the evidence-based guidelines with higher AGREE Ⅱ scores considering local adaption.

•

This systematic review comprehensively maps the recommendations of the latest international breast screening guidelines, providing valuable tools for clinical decision making in different settings.

•

Most guidelines recommend annual or biennial mammographic screening between 40 and 74 years for the average-risk populations and annual MAM or annual MRI starting from a younger age for the high-risk populations. However, there are indeed discrepancies in screening age, methods, and intervals among countries.

•

High-quality evidence and rigorous methodology are the keys to guidance development, but current guidelines vary in methodological quality.

Economic evaluations of mammography to screen for breast cancer in low- and middle-income countries: A systematic review

Background

Low- and middle-income countries (LMICs) have limited resources compared to high-income countries (HICs). Therefore, it is critical that LMICs implement cost-effective strategies to reduce the burden of breast cancer. This study aimed to answer the question of whether mammography is a cost-effective breast cancer screening method in LMICs.

Methods

A systematic article search was conducted through Medline, Embase, Web of Science, and Econlit. Studies were included only if they conducted a full economic evaluation and focused on mammography screening in LMICs. Two reviewers screened through the title and abstract of each article and continued with full-text selection. Data were extracted and synthesized narratively. Quality assessment for each included study was conducted using the Consensus Health Economic Criteria (CHEC) extended checklist.

Results

This review identified 21 studies economically evaluating mammography as a breast cancer screening method in LMICs. Eighteen of these studies concluded that mammography screening was a cost-effective strategy. Most studies (71%) were conducted in upper-middle-income countries (Upper MICs). The quality of the studies varied from low to good. Important factors determining cost-effectiveness are the target age group (eg, 50-59 years), the screening interval (eg, biennial or triennial), as well as any combination with other breast cancer control strategies (eg, combination with treatment strategy for breast cancer patients).

Conclusions

Mammography screening appeared to be a cost-effective strategy in LMICs, particularly in Upper MICs. More studies conducted in lower-middle-income and low-income countries are needed to better understand the cost-effectiveness of mammography screening in these regions.

Health system costs of a breast cancer early diagnosis programme in a rural district of Rwanda: a retrospective, cross-sectional economic analysis

OBJECTIVES

This study aimed to quantify the health system cost of the first 2 years of a Breast Cancer Early Detection (BCED) programme in a rural district in Rwanda. We also aimed to estimate the cost of implementing the programme in other districts with different referral pathways and identify opportunities for enhanced cost efficiency.

DESIGN

Retrospective, cross-sectional analysis using time-driven activity-based costing, based on timed patient clinical encounters, retrospective patient data and unit costs of resources abstracted from administrative and finance records.

SETTING

The BCED programme focused on timely evaluation of individuals with breast symptoms. The study evaluated the health system cost of the BCED programme at seven health centres (HCs) in Burera district and Butaro Cancer Centre of Excellence (BCCOE) at Butaro District Hospital.

OUTCOME MEASURES

Health system costs per patient visit and cost per cancer diagnosed were quantified. Total start-up and recurring operational costs were also estimated, as well as health system costs of different scale-up adaptations in other districts.

RESULTS

One-time start-up costswere US$36 917, recurring operational costswere US$67 711 and clinical costswere US$14 824 over 2 years. Clinical breast examinations (CBE) at HCs cost US$3.27/visit. At BCCOE, CBE-only visits cost US$13.47/visit, CBE/ultrasound US$14.79/visit and CBE/ultrasound/biopsy/pathology US$147.81/visit. Overall, clinical cost per breast cancer diagnosed was US$1482. Clinicalcost drivers were personnel at HCs (55%) and biopsy/pathology supplies at BCCOE (46%). In other districts, patients experience a longer breast evaluation pathway, adding about US$14.00/patient; this could be decreased if ultrasound services were decentralised.

CONCLUSION

Clinical costs associated with BCED services at HCs were modest, similar to other general outpatient services. The BCED programme's start-up and operational costs were high but could be reduced by using local trainers and virtual mentorship. In other districts, decentralising ultrasound and/or biopsies to district hospitals could reduce costs.

Radiology volunteers to support a breast cancer screening program in Peru: Description of the project, preliminary results, and impressions

Breast cancer is the second most common cancer in Peruvian women. Due to limitations in national breast cancer screening programs, especially in rural areas, more than 50% of cases of breast cancer in Peru are diagnosed in advanced stages. In collaboration with a local clinic registered as a nongovernmental organization (CerviCusco), RAD-AID International aims to create a sustainable diagnostic structure to improve breast cancer screening in Cuzco. With the support of local, national, and international partners that have collaborated in analyzing radiological resources, raising awareness in the population, acquiring equipment, training clinical staff, and building referral networks, our teams of radiologists, included in the RAD-AID team, have participated in training CerviCusco staff in breast ultrasound, thus enabling additional training for radiology residents through a regulated international collaboration.

The iBreastExam versus clinical breast examination for breast evaluation in high risk and symptomatic Nigerian women: a prospective study

BACKGROUND

The iBreastExam electronically palpates the breast to identify possible abnormalities. We assessed the iBreastExam performance compared with clinical breast examination for breast lesion detection in high risk and symptomatic Nigerian women.

METHODS

This prospective study was done at the Obafemi Awolowo University Teaching Hospital Complex (OAUTHC) in Nigeria. Participants were Nigerian women aged 40 years or older who were symptomatic and presented with breast cancer symptoms or those at high risk with a first-degree relative who had a history of breast cancer. Participants underwent four breast examinations: clinical breast examination (by an experienced surgeon), the iBreastExam (performed by recent nursing school graduates, who finished nursing school within the previous year), ultrasound, and mammography. Sensitivity, specificity, positive predictive values (PPV), and negative predictive values (NPV) of the iBreastExam and clinical breast examination for detecting any breast lesion and suspicious breast lesions were calculated, using mammography and ultrasound as the reference standard.

FINDINGS

Between June 19 and Dec 5, 2019, 424 Nigerian women were enrolled (151 [36%] at high risk of breast cancer and 273 [64%] symptomatic women). The median age of participants was 46 years (IQR 42-52). 419 (99%) women had a breast imaging-reporting and data system (BI-RADS) assessment and were included in the analysis. For any breast finding, the iBreastExam showed significantly better sensitivity than clinical breast examination (63%, 95% CI 57-69 vs 31%, 25-37; p<0·0001), and clinical breast examination showed significantly better specificity (94%, 90-97 vs 59%, 52-66; p<0·0001). For suspicious breast findings, the iBreastExam showed similar sensitivity to clinical breast examination (86%, 95% CI 70-95 vs 83%, 67-94; p=0·65), and clinical breast examination showed significantly better specificity (50%, 45-55 vs 86%, 83-90; p<0·0001). The iBreastExam and clinical breast examination showed similar NPVs for any breast finding (56%, 49-63 vs 52%, 46-57; p=0·080) and suspicious findings (98%, 94-99 vs 98%, 96-99; p=0·42), whereas the PPV was significantly higher for clinical breast examination in any breast finding (87%, 77-93 vs 66%, 59-72; p<0·0001) and suspicious findings (37%, 26-48 vs 14%, 10-19; p=0·0020). Of 15 biopsy-confirmed cancers, clinical breast examination and the iBreastExam detected an ipsilateral breast abnormality in 13 (87%) women and missed the same two cancers (both <2 cm).

INTERPRETATION

The iBreastExam by nurses showed a high sensitivity and NPV, but lower specificity than surgeon's clinical breast examination for identifying suspicious breast lesions. In locations with few experienced practitioners, the iBreastExam might provide a high sensitivity breast evaluation tool. Further research into improved specificity with device updates and cost feasibility in low-resource settings is warranted.

Breast cancer burden in Africa: evidence from GLOBOCAN 2018

BACKGROUND

Breast cancer is the leading malignancy in African females. This study aims to examine the breast cancer burden in Africa using recently released GLOBOCAN 2018 estimates.

METHODS

The incidence and mortality estimates of age- and country-wise burden of breast cancer in 54 African countries were obtained from GLOBOCAN 2018.

RESULTS

In Africa, breast cancer caused 74 072 deaths, and 168 690 cases were estimated to have occurred in 2018. The age-standardized incidence rate stood at 37.9/100 000 in Africa, varying from 6.9/100 000 in the Gambia to 69.6/100 000 in Mauritius. The age-standardized mortality rate stood at 17.2/100 000 in 2018, ranging from 4/100 000 in the Gambia to 29.1/100 000 in Somalia in 2018. Nigeria was the leading country in terms of absolute burden with 26 310 cases and 11 564 deaths, followed by Egypt with 23 081 new cases and 9254 deaths. The mortality-to-incidence ratio for Africa stood at 0.44, varying from 0.24 in Libya to 0.68 in the Central African Republic.

CONCLUSION

To tackle breast cancer burden in Africa, the main challenges are late-stage disease presentation, lack of screening and therapeutic infrastructure, lack of awareness and limited resources.

Cancer and severe mental illness in low- and middle-income countries: The challenges and outlook for the future

OBJECTIVE

Patients with severe mental illness (SMI) face health inequalities that lead to under treatment of diseases such as cancer and result in increased mortality. There is literature addressing this issue for SMI patients in high-income countries but few for those in low- and middle-income countries. This review aims to draw attention to the health inequalities and the compounding factors faced by SMI patients in low- and middle-income countries. The relevance of integration of psycho-oncology in the care of SMI patients with cancer is integral to reduce disparities and address varied contributory factors.

METHODS

The literature review was conducted by searching through two databases which includes PubMed and Google Scholar. We searched for articles using keyword search terms: severe mental illness, SMI, schizophrenia, bipolar disorder, cancer, low- middle-income countries, low- and middle-income countries, psycho-oncology, HPV vaccine, cancer incidence, cancer mortality, cancer control, cancer screening, cancer treatment and palliative care.

RESULTS

A total of 80 research articles were included in our literature review. We found that there was an increased requirement for adapting to the changing disease landscape in low- and middle-income countries. An improvement on aspects such as vaccination, screening and prevention is necessary, and also efforts to change social stance towards SMI is crucial.

CONCLUSION

There is an increase incidence of cancer in low- and middle-income countries, and the number of patients with SMI in low- and middle-income countries is also rising. This is due to social, psychological, economical and healthcare factors. Low- and middle-income countries must consider improving these aspects in order to adapt to the changing landscape.

The impact of scaling up access to treatment and imaging modalities on global disparities in breast cancer survival: a simulation-based analysis

BACKGROUND

Female breast cancer is the most commonly diagnosed cancer in the world, with wide variations in reported survival by country. Women in low-income and middle-income countries (LMICs) in particular face several barriers to breast cancer services, including diagnostics and treatment. We aimed to estimate the potential impact of scaling up the availability of treatment and imaging modalities on breast cancer survival globally, together with improvements in quality of care.

METHODS

For this simulation-based analysis, we used a microsimulation model of global cancer survival, which accounts for the availability and stage-specific survival impact of specific treatment modalities (chemotherapy, radiotherapy, surgery, and targeted therapy), imaging modalities (ultrasound, x-ray, CT, MRI, PET, and single-photon emission computed tomography [SPECT]), and quality of cancer care, to simulate 5-year net survival for women with newly diagnosed breast cancer in 200 countries and territories in 2018. We calibrated the model to empirical data on 5-year net breast cancer survival in 2010-14 from CONCORD-3. We evaluated the potential impact of scaling up specific imaging and treatment modalities and quality of care to the mean level of high-income countries, individually and in combination. We ran 1000 simulations for each policy intervention and report the means and 95% uncertainty intervals (UIs) for all model outcomes.

FINDINGS

We estimate that global 5-year net survival for women diagnosed with breast cancer in 2018 was 67·9% (95% UI 62·9-73·4) overall, with an almost 25-times difference between low-income (3·5% [0·4-10·0]) and high-income (87·0% [85·6-88·4]) countries. Among individual treatment modalities, scaling up access to surgery alone was estimated to yield the largest survival gains globally (2·7% [95% UI 0·4-8·3]), and scaling up CT alone would have the largest global impact among imaging modalities (0·5% [0·0-2·0]). Scaling up a package of traditional modalities (surgery, chemotherapy, radiotherapy, ultrasound, and x-ray) could improve global 5-year net survival to 75·6% (95% UI 70·6-79·4), with survival in low-income countries improving from 3·5% (0·4-10·0) to 28·6% (4·9-60·1). Adding concurrent improvements in quality of care could further improve global 5-year net survival to 78·2% (95% UI 74·9-80·4), with a substantial impact in low-income countries, improving net survival to 55·3% (42·2-67·8). Comprehensive scale-up of access to all modalities and improvements in quality of care could improve global 5-year net survival to 82·3% (95% UI 79·3-85·0).

INTERPRETATION

Comprehensive scale-up of treatment and imaging modalities, and improvements in quality of care could improve global 5-year net breast cancer survival by nearly 15 percentage points. Scale-up of traditional modalities and quality-of-care improvements could achieve 70% of these total potential gains, with substantial impact in LMICs, providing a more feasible pathway to improving breast cancer survival in these settings even without the benefits of future investments in targeted therapy and advanced imaging.

Feasibility of Fine-Needle Aspiration Biopsy and Rapid On-Site Evaluation for Immediate Triage in Breast Cancer Screening in Tanzania

PURPOSE

Clinical breast examination (CBE) is one of the most common methods used for early detection of breast cancer in low- and middle-income countries. CBE alone is limited by lack of specificity and may result in unnecessary diagnostic procedures. We evaluated the feasibility of integrating CBE, fine-needle aspiration biopsy (FNAB), and rapid on-site evaluation (ROSE) in triaging palpable breast masses for specialized cancer care.

MATERIALS AND METHODS

An intensive breast cancer screening event was conducted at a national trade fair by a multidisciplinary team of care providers targeting a healthy population in Dar es Salaam, Tanzania. All adults age ≥ 18 years were invited to participate. CBE was performed by oncologists and/or pathologists. FNAB was performed by a pathologist on palpable masses that were then categorized as benign, indeterminate, or suspicious for malignancy or definitively malignant based on ROSE.

RESULTS

A total of 208 individuals (207 females, one male; median age, 36 years; range, 18-68 years) were screened. Most (90.8%, 189 of 208) had normal findings, whereas 7.2% (15 of 208), 1% (2 of 208), and 1% (2 of 208) had a palpable mass, breast pain, and nipple discharge, respectively. Two participants had lesions too small for palpation-guided biopsy and clinically consistent with fibroadenomas; the participants were counseled, and observation was recommended. FNAB was performed on 13 breast masses, with 9 of 13 (69%) categorized as benign and 4 of 13 (31%) suspicious for malignancy. Final cytopathologic review of referred patients confirmed one case to be breast adenocarcinoma, one was suggestive of fibroadenoma, and two showed inflammations.

CONCLUSION

Integration of CBE with ROSE and FNAB was feasible in a breast cancer screening program in Tanzania. In settings with constrained resources for cancer care, this may be an effective method for triaging patients with breast masses.

Breast cancer early detection and diagnostic capacity in Uganda

BACKGROUND

Greater than 80% of women presenting for breast cancer treatment in Uganda have late-stage disease, which is attributable to a dysfunctional referral system and a lack of recognition of the early signs and symptoms among primary health care providers, and compounded by the poor infrastructure and inadequate human capacity. Improving the breast health care system requires a systemic approach beginning with situational analysis to identify systematic gaps that prevent sustainable improvements in outcome.

METHODS

The authors performed a situational analysis of the breast health care system using methods developed by the Breast Health Global Initiative. Based on their findings, they developed a series of recommendations for strengthening the health system for the early diagnosis of breast cancer based on clinical detection, referral, tissue sampling, and diagnosis.

RESULTS

Deficits in the recognition of breast cancer signs and symptoms, the underuse of clinical breast examination as a diagnostic and/or screening tool, the centralization of diagnostic tests (radiology and pathology), reliance on excisional biopsies rather than needle biopsies, and a lack of trained professionals and knowledge of the referral system all contribute to significant health system delays.

CONCLUSIONS

To strengthen referral networks and improve the early diagnosis of breast cancer in Uganda, national referral hospitals should provide educational programs to primary health care providers in community health centers (CHCs), at which the majority of women first present with symptoms. At secondary district-level facilities in which imaging and tissue sampling can be performed, the capacity for diagnostic testing could be increased through task shifting of basic interpretation (abnormal vs normal) from specialists to nonspecialists using networking technology to facilitate remote oversight from specialists at the national referral hospitals.

Can pathology diagnostic services for cancer be stratified and serve global health?

BACKGROUND

Before initiating cancer therapy, a diagnostic tumor tissue sample evaluated within a pathology laboratory by a pathologist is essential to confirm the malignancy type and provide key prognostic factors that direct the treatment offered.

METHODS

Pathology evaluation includes multiple expensive reagents, complex equipment, and both laboratory and pathologist technical skills. By using breast cancer as an example, at a minimum, key tumor prognostic information required before the initiation of treatment includes subtype, tumor grade, tumor size, lymph node status when possible, and biomarker expression determined by immunohistochemistry for estrogen receptor. The additional determination of biomarker expression of progesterone receptor and human epidermal growth factor receptor (HER2) is the standard of care in high-resource settings, but assays may not be affordable in low-income and middle-income countries.

RESULTS

With positive tests, patients are eligible for either tamoxifen (for estrogen receptor-positive/progesterone receptor-positive cancers) or monoclonal antibody therapy (for HER2-positive cancers). For settings in which endocrine therapy and/or HER2-targeted therapy is unavailable, biomarker studies have no utility, and high-resource setting standards for pathology evaluation and reporting are unachievable. Resource-stratified pathology evaluation guidelines in cancer diagnosis have not been developed, in contrast to excellent comprehensive, resource-stratified clinical guidelines for use in low-income and middle-income countries, and these are long overdue.

CONCLUSIONS

The challenges of pathology evaluation in the context of global health are being met by innovative solutions, which may change the face of pathology practice.

Why women with breast cancer presented late to health care facility in North-west Ethiopia? A qualitative study

BACKGROUND

Although early diagnosis is a key determinant factor for breast cancer survival, delay in presentation and advanced stage diagnosis are common challenges in low and middle income countries including Ethiopia. Long patient delays in presentation to health facility and advanced stage diagnosis are common features in breast cancer care in Ethiopia but the reasons for patient delays are not well explored in the country. Therefore we aimed to explore the reasons for patient delay in seeking early medical care for breast cancer in North-west Ethiopia.

METHODS

A qualitative study was conducted from November to December 2019 using in-depth interviews from newly diagnosed breast cancer patients in the two comprehensive specialized hospitals in North West Ethiopia. Verbal informed consent was taken from each participant before interviews. A thematic content analysis was performed using Open Code software version 4.02.

RESULTS

Lack of knowledge and awareness about breast cancer, cultural and religious beliefs, economic hardships, lack of health care and transportation access, fear of surgical procedures and lack of trusts on medical care were the major reasons for late presentation of breast cancer identified from the patient's narratives.

CONCLUSIONS

The reasons for late presentation of patients to seek early medical care for breast cancer had multidimensional nature in Northwest Ethiopia. Health education and promotion programs about breast cancer should be designed to increase public awareness to facilitate early detection of cases before advancement on the existing health care delivery system.

A review of barriers and facilitators to mammography in Asian women

Aim

Breast cancer is the most common cancer among women in Asia and one of the major health problems in most countries in the region. Despite extensive advances in treatment, early diagnosis is one of the main methods for increasing the survival rate. It is necessary to evaluate the barriers and facilitators of screening in different societies. This study was conducted to identify the barriers and facilitators of mammography in Asia.

Materials and methods

To identify the barriers and facilitators of mammography in Asia, a comprehensive search was carried out in databases such as Medline, Web of Science Core Collection and Scopus using keywords, including breast cancer, screening, mammography, barriers, facilitators and the names of each Asian country, as well as a combination of these keywords were used to help the search. Full-text, English language and original articles were included in this study.

Results

In total, 71 articles were entered into the study. The findings of this study revealed various barriers to mammography in Asian women, including knowledge, sociodemographic factors, cost and insurance, cultural factors, belief, attitude and feeling, fear, pain and embarrassment, self-efficacy, religious, psychological factors, time constraint, fatalism, professional recommendations, communication, social support and access. Also, knowledge, attitude and belief, perceived risk, professional and social factors were found to be facilitators of mammography.

Conclusion

Knowing the barriers and facilitators to access mammography is the first step in the development of a successful screening program. Awareness and various personal, professional and social factors have emerged as the major barriers to access to mammography in most Asian countries.

Factors associated with breast cancer awareness and breast self-examination in Fiji and Kashmir India - a cross-sectional study

BACKGROUND

In low-income countries breast cancer awareness (BCA) is essential to reduce the proportion of advanced stage presentations of breast cancer. There is a lack of studies using multivariable techniques to explore factors related to BCA in low-income countries. The objective of this study was to identify to what extent women in Fiji and Kashmir, India have BCA and practice breast self-examination (BSE) as well as factors associated with BCA and BSE.

METHODS

A survey of women aged ≥18 years was conducted in Fiji and Kashmir, India to assess BCA and rates of BSE. Comparison between Fiji and Kashmir was done using student's t-test for continuous data and chi-square for binary data. Factors associated with BCA and BSE were analysed using a multivariable logistic regression for Fiji and Kashmir separately.

RESULTS

Data were collected from 399 and 1982 women in Kashmir and Fiji, respectively. Of 1968 women in Fiji 57% were deemed to have an acceptable BCA compared to only 7.3% of 395 women in Kashmir. Having some education was associated with having BCA with an odds ratio of 4.7 (1.7-13) in Fiji and 10 (1.7-59) in Kashmir. Of 1976 women in Fiji 40% had tertiary education while 40% of 392 women in Kashmir had no education at all. The marital status was similar in both samples (n = 1973 and 395) with 68-69% being married and 21-26% being single. The lack of female doctors or nurses with whom to discuss issues, was perceived as a problem in both countries.

CONCLUSIONS

The key finding is an association between having any level of education and BCA. This correlation was much stronger than for a family history of breast cancer and BCA. Hence, general education to illiterate women may reduce the proportion of women in low-income countries presenting with advanced-stage breast cancer.

Late-Stage Diagnosis and Associated Factors Among Breast Cancer Patients in South and Southwest Ethiopia: A Multicenter Study

BACKGROUND

Breast cancer is a leading cause of cancer death in women in low- and middle-income countries, largely because of late-stage diagnosis. Yet studies are very limited in the Ethiopian context. Therefore, we determined the occurrence of late-stage disease and associated factors in selected public hospitals in south and southwest Ethiopia.

PATIENTS AND METHODS

A 5-year retrospective cross-sectional study was conducted on breast cancer patient medical records from January 2013 to December 2017 in 6 hospitals. Multivariable logistic regression was performed to identify factors associated with late-stage disease (stage III and IV). Adjusted odds ratios (AOR) with 95% confidence intervals were used. P < .05 was considered statistically significant.

RESULTS

Overall, 426 breast cancer patients were identified, and 72.5% were diagnosed with late-stage disease. The mean ± standard deviation patient age was 42.8 ± 13.4 years. Factors associated with late diagnosis were patient delay in seeking care (AOR = 2.50; 95% confidence interval [CI], 1.51-4.16); health system delays (AOR = 1.62; 95% CI, 1.02-2.59); female sex (AOR = 3.46; 95% CI, 1.50-7.98); rural residence (AOR = 2.37; 95% CI, 1.45-3.86); chief complaint of breast lump (AOR = 3.01; 95% CI, 1.49-6.07); and history of comorbidities (AOR = 1.72; 95% CI, 1.02-2.91).

CONCLUSION

The majority of patients were diagnosed with late-stage diagnosis of breast cancer. Patient delays in seeking care, health system delays, being female, rural residence, and patient comorbidities were associated factors. These findings provide evidence that efforts to increase public and health provider awareness to promote early breast cancer diagnosis, particularly in rural areas, are needed in south and southwest Ethiopia.

Optimizing care of breast cancer patients from low resource countries who immigrate to New York City: A case series from a large public hospital

Global disparities in breast cancer care become particularly evident when patients seek definitive care in the United States (USA) after receiving a breast cancer diagnosis and initiating care in low- and middle-income countries (LMICs). We performed a retrospective review of 26 patients with breast cancer who immigrated from LMICs and received care at Bellevue Hospital. Fifteen (58%) presented with advanced disease (stage III or IV), including 7 (27%). All 26 patients required diagnostic work-up in the USA, and all 19 (73.1%) patients with stage 0-III disease underwent surgical excision. Patients from LMICs frequently present with advanced disease and in varying stages of breast cancer treatment. Improving communication with previous providers and fostering a collaborative approach with the international community are essential to developing efficacious treatment plans and improving oncologic outcomes.

Training Nonradiologist Clinicians in Diagnostic Breast Ultrasound in Rural Rwanda: Impact on Knowledge and Skills

OBJECTIVE

To assess the effectiveness of diagnostic breast ultrasound training provided for general practitioners and nurses in Rwanda via intensive in-person and subsequent online supervision and mentorship.

METHODS

Four breast radiologists from Brigham and Women's Hospital trained two general practitioner physicians and five nurses in Rwanda over 9 total weeks of in-person training and 20 months of remote mentorship using electronic image review with emailed feedback. Independently recorded assessments were compared to calculate the sensitivity and specificity of trainee assessments, with radiologist assessments as the gold standard. We compared performance in the first versus second half of the training.

RESULTS

Trainees' performance on written knowledge assessments improved after training (57.7% versus 98.1% correct, P = .03). Mean sensitivity of trainee-performed ultrasound for identifying a solid breast mass was 90.6% (SD 4.2%) in the first half of the training (period 1) and 94.0% (SD 6.7%) in period 2 (P = .32). Mean specificity was 94.7% (SD 5.4%) in period 1 and 100.0% (SD 0) in period 2 (P = .10). Mean sensitivity for identifying a medium- or high-suspicion solid mass increased from 79.2% (SD 11.0%) in period 1 to 96.3% (SD 6.4%) in period 2 (P = .03). Specificity was 84.4% (SD 15.0%) in period 1 and 96.7% (SD 5.8%) in period 2 (P = .31).

DISCUSSION

Nonradiologist clinicians (doctors and nurses) in a rural sub-Saharan African hospital built strong skills in diagnostic breast ultrasound over 23 months of combined in-person training and remote mentorship. The sensitivity of trainees' assessments in identifying masses concerning for malignancy improved after sustained mentorship. Assessment of impact on patient care and outcomes is ongoing.

A Global Perspective on Screening

Breast cancer is emerging as a major global public health problem. Incidence and mortality continues to rise in low- and middle-income countries (LMICs). A significant and growing disparity exists between high-income countries and LMICs in the availability of screening services and associated preventable mortality. However, population imaging-based screening programs are not appropriate for all settings. Planners should perform a thorough assessment of the target setting prior to implementing any breast cancer detection program, as appropriate guidelines vary according to the resources available. Financial, social, and cultural barriers to breast cancer care need to be addressed to sustainably improve the morbidity and mortality of the populations and make efficient use of available services. Creative approaches, such as mobile and portable imaging and bundling of services, can facilitate the installation of early breast cancer detection programs in LMICs. While image-based screening programs are not initially resource-appropriate in many LMICs, planners can work towards this goal as part of their comprehensive breast cancer detection strategy.

Presentation intervals and the impact of delay on breast cancer progression in a black African population

Background

The help-seeking interval and primary-care interval are points of delays in breast cancer presentation. To inform future intervention targeting early diagnosis of breast cancer, we described the contribution of each interval to the delay and the impact of delay on tumor progression.

Method

We conducted a multicentered survey from June 2017 to May 2018 hypothesizing that most patients visited the first healthcare provider within 60 days of tumor detection. Inferential statistics were by t-test, chi-square test, and Wilcoxon-Signed Rank test at p-value 0.05 or 95% confidence limits. Time-to-event was by survival method. Multivariate analysis was by logistic regression.

Results

Respondents were females between 24 and 95 years (n = 420). Most respondents visited FHP within 60 days of detecting symptoms (230 (60, 95% CI 53–63). Most had long primary-care (237 of 377 (64 95% CI 59–68) and detection-to-specialist (293 (73% (95% CI 68–77)) intervals. The primary care interval (median 106 days, IQR 13–337) was longer than the help-seeking interval (median 42 days, IQR 7–150) Wilcoxon signed-rank test p = 0.001. There was a strong correlation between the length of primary care interval and the detection-to-specialist interval (r = 0.9, 95% CI 0.88–0.92). Patronizing the hospital, receiving the correct advice, and having a big tumor (> 5 cm) were associated with short intervals.

Tumors were detected early, but most became advanced before arriving at the specialist clinic. The difference in tumor size between detection and arriving at a specialist clinic was 5.0 ± 4.9 cm (95% CI 4.0–5.0). The hazard of progressing from early to locally advanced disease was least in the first 30 days (3%). The hazard was 31% in 90 days.

Conclusion

Most respondents presented early to the first healthcare provider, but most arrived late at a specialist clinic. The primary care interval was longer than the help-seeking interval. Most tumors were early at detection but locally advanced before arriving in a specialist clinic. Interventions aiming to shorten the primary care interval will have the most impact on time to breast cancer presentation for specialist oncology care in Nigeria.

Breast Imaging and Image-guided Intervention in Tanzania: Initial Experience

Breast imaging capacity in Tanzania is currently very limited. In a country of almost 60 million people, mammographic units are exceedingly rare. The few existing units are compromised by lack of maintenance and quality control and extremely limited technologist training. Breast cancer incidence continues to increase in East Africa, while the ability to accurately diagnose and differentiate benign and malignant breast disease remains a challenge. However, as ultrasound technology improves and becomes more affordable, there is increased access to devices including hand-held point of care ultrasound. Additionally, there has been a recent expansion in the training of academic radiologists in Tanzania, creating an opportunity for possible sustainable improvement of breast imaging and intervention. Our initial efforts at the Muhimbili Academic Medical Center (MAMC) included social media advertising for symptomatic and asymptomatic women, followed by screening (clinical breast exam) and subsequent ultrasound imaging of symptomatic women. We then initiated a workflow for ultrasound-guided breast intervention, performed biopsies, reviewed results by local pathologists, and brought the postbiopsy patients back for radiologic-pathologic correlation, wound assessment, and coordination of follow-up and treatment.

Prevalence of Themes Linked to Delayed Presentation of Breast Cancer in Africa: A Meta-Analysis of Patient-Reported Studies

PURPOSE

The prevalence of themes linked to delay in presentation of breast cancer (BC) and their underlying factors vary considerably throughout Africa. Regional differences and trends are largely unreported. The purpose of this research was to provide summary estimates of the prevalence and distribution of the themes and underlying factors linked to delay in the presentation of BC, regional variation, and trends in an effort to identify targets for intervention.

DESIGN

We screened articles found through PubMed/Medline, African Journal OnLine, Science Direct, Google/Google Scholar, and ResearchGate. We included patient-reported surveys on the reasons linked to delayed presentation under 6 previously identified themes: symptom misinterpretation, fear, preference for alternative care, social influence, hospital-related factors, and access factors. The meta-analytical procedure in MetaXL used the quality-effect model.

RESULTS

Twelve of the 236 identified articles were eligible for this review. The overall summary estimate of late presentation (> 90 days) was 54% (95% CI, 23 to 85) and was worst in the eastern and central regions. Symptom misinterpretation was the most common theme (50%; 95% CI, 21 to 56), followed by fear (17%; 95% CI, 3 to 27), hospital-related theme (11%; 95% CI, 1 to 21), preference for alternative care (10%; 95% CI, 0 to 21), social influence (7%; 95% CI, 0 to 14), and access-related theme (6%; 95% CI, 0 to 13). The most common factor underlying symptom misinterpretation was mischaracterizing the breast lesion as benign (60%; 95% CI, 4 to 100) which surpassed lack of awareness in the last decade. Misdiagnosis and failure to refer were the dominant hospital-related factors.

CONCLUSION

Modifiable factors such as mischaracterizing malignant masses as benign, fear, misdiagnosis, and failure to refer were the prevalent factors contributing to delays throughout Africa. These factors are promising targets for intervention.

A phased approach to implementing the Breast Imaging Reporting and Data System (BI-RADS) in low-income and middle-income countries

BACKGROUND

Successful breast cancer detection programs rely on standardized reporting and interpreting systems, such as the Breast Imaging Reporting and Data System (BI-RADS), to improve system performance. In low-income and middle-income countries, evolving diagnostic programs have insufficient resources to either fully implement BI-RADS or to periodically evaluate the program's performance, which is a necessary component of BI-RADS. This leads to inconsistent breast ultrasound interpretation and a failure to improve performance.

METHODS

The authors applied the Breast Health Global Initiative's phased implementation strategy to implement diagnostic ultrasound and BI-RADS within the context of a limited-resource setting.

RESULTS

The authors recommended starting with triage ultrasound to distinguish suspicious masses from normal breast tissue and benign masses such as cysts because the majority of health workers performing ultrasounds at this level have minimal breast imaging experience. Transitioning to full diagnostic ultrasound with condensed or full BI-RADS should occur after performance and quality metrics have been met.

CONCLUSIONS

Transitioning through these phases across facilities likely will occur at different times, particularly in rural versus urban settings.

When breast cancer is detected and treated early, the chances of survival are very high. However, women in many settings face complex barriers to early detection, including social, economic, geographic, and other interrelated factors, which can limit their access to timely, affordable, and effective breast health care services. Previously, the Breast Health Global Initiative (BHGI) developed resource-stratified guidelines for the early detection and diagnosis of breast cancer. In this consensus article from the sixth BHGI Global Summit held in October 2018, the authors describe phases of early detection program development, beginning with management strategies required for the diagnosis of clinically detectable disease based on awareness education and technical training, history and physical examination, and accurate tissue diagnosis. The core issues address include finance and governance, which pertain to successful planning, implementation, and the iterative process of program improvement and are needed for a breast cancer early detection program to succeed in any resource setting. Examples are presented of implementation, process, and clinical outcome metrics that assist in program implementation monitoring. Country case examples are presented to highlight the challenges and opportunities of implementing successful breast cancer early detection programs, and the complex interplay of barriers and facilitators to achieving early detection for breast cancer in real-world settings are considered.

Ultrasound for Breast Cancer Detection Globally: A Systematic Review and Meta-Analysis

PURPOSE

Mammography is not always available or feasible. The purpose of this systematic review and meta-analysis is to assess the diagnostic performance of ultrasound as a primary tool for early detection of breast cancer.

MATERIALS AND METHODS

For this systematic review and meta-analysis, we comprehensively searched PubMed and SCOPUS to identify articles from January 2000 to December 2018 that included data on the performance of ultrasound for detection of breast cancer. Studies evaluating portable, handheld ultrasound as an independent detection modality for breast cancer were included. Quality assessment and bias analysis were performed with the Quality Assessment of Diagnostic Accuracy Studies-2 tool. Sensitivity analyses and meta-regression were used to explore heterogeneity. The study protocol has been registered with the international prospective register of systematic reviews (PROSPERO identifier: CRD42019127752).

RESULTS

Of the 526 identified studies, 26 were eligible for inclusion. Ultrasound had an overall pooled sensitivity and specificity of 80.1% (95% CI, 72.2% to 86.3%) and 88.4% (95% CI, 79.8% to 93.6%), respectively. When only low- and middle-income country data were considered, ultrasound maintained a diagnostic sensitivity of 89.2% and specificity of 99.1%. Meta-analysis of the included studies revealed heterogeneity. The high sensitivity of ultrasound for the detection of breast cancer was not statistically significantly different in subgroup analyses on the basis of mean age, risk, symptoms, study design, bias level, and study setting.

CONCLUSION

Given the increasing burden of breast cancer and infeasibility of mammography in certain settings, we believe these results support the potential use of ultrasound as an effective primary detection tool for breast cancer, which may be beneficial in low-resource settings where mammography is unavailable.

Perceived barriers to early diagnosis of breast Cancer in south and southwestern Ethiopia: a qualitative study

Background

Early diagnosis is a key determinant of breast cancer prognosis and survival. More than half of breast cancer cases are diagnosed at an advanced stage in Ethiopia, and the barriers to early diagnosis in this country are not well understood. We aimed to identify the perceived barriers to early diagnosis of breast cancer from the perspective of patients and health care providers in south and southwestern Ethiopia.

Methods

A qualitative study was conducted from March to April 2018 using in-depth interviews of breast cancer patients and breast cancer health care providers from six public hospitals located in urban and rural areas of south and southwestern Ethiopia. All participants provided verbal consent before participating. A thematic analysis was performed using Open Code 4.02.

Results

Twelve breast cancer patients and thirteen health care providers were included in the study. Patient and health-system related barriers to early diagnosis of breast cancer were identified. Patient-related barriers were lack of knowledge and awareness of breast cancer, belief in traditional medicine and religious practices for treatment, and lack of social and financial support to seek care at a medical facility. Health-system related barriers were misdiagnosis of breast cancer, long distance to referral facilities, high cost of diagnostic services, long waiting time for diagnostic tests, and lack of screening and diagnostic tests in local facilities.

Conclusions

Early diagnosis of breast cancer is affected by multiple barriers in south and southwestern Ethiopia. Awareness campaigns and education about the disease, prevention, and early detection are needed to increase early diagnosis of breast cancer. Opportunities exist to improve early diagnosis and timely treatment in rural areas.

Can Breast Self-examination and Clinical Breast Examination Along With Increasing Breast Awareness Facilitate Earlier Detection of Breast Cancer in Populations With Advanced Stages at Diagnosis?

Breast cancer is the most common form of cancer among women worldwide. Early detection is central to improving disease outcomes. Three main screening methods - mammography, breast self-examination (BSE), and clinical breast examination (CBE) - have been developed and tested in Western nations. There is ongoing debate regarding the efficacy of BSE and CBE in terms of mortality reduction, and a number of international organizations no longer recommend them as screening methods. In technically less developed countries, however, where women are usually diagnosed with breast cancer at advanced stages and younger ages, the benefits of BSE and CBE might outweigh the harm and facilitate early detection of breast cancer. This paper reviews the history of BSE and CBE and discusses their value as early detection methods. It can contribute to informed decision-making by health policy-makers and clinicians who are involved in breast cancer screening in the developing world to improve women's well-being.

Factors associated with time interval between the onset of symptoms and first medical visit in women with breast cancer

Women presenting with advanced breast cancer tumors are common in Brazil. Little is known about factors contributing to the delay in seeking care. The aim of this study was to identify factors associated with longer time intervals between the onset of breast cancer symptoms and the first medical visit in the Federal District, Brazil. The analysis included 444 symptomatic women with incident breast cancer, interviewed between September, 2012 and September, 2014, during their admission for breast cancer treatment in nine public hospitals in the Federal District. Patients with metastatic disease at diagnosis were not included in this study. The outcome was time interval between symptom onset and the first medical visit, whether > 90 (34% of patients) or ≤ 90 days. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (95%CI). In the multivariate analysis, the > 90 day interval was significantly associated with patients not performing mammography and/or breast ultrasound in the two years prior to breast cancer diagnosis (OR = 1.97; 95%CI: 1.26-3.08), and with more advanced stages (OR = 1.72; 95%CI: 1.10-2.72). Furthermore, there was a lower chance of delay in patients with higher levels of education (OR = 0.95; 95%CI: 0.91-0.99). A relatively high proportion of breast cancer patients in the Brazilian Federal District experienced delay to attend the first medical consultation after the symptoms onset. Increasing breast cancer awareness, especially among women with low educational levels and those not participating in mammography screening programs could contribute to reduce this delay.

Mapping evidence on women's knowledge and practice of breast self-examination in sub-Saharan Africa: a scoping review protocol

BACKGROUND

Globally, breast cancer is the most common malignant condition in women. Breast self-examination practice following correct procedure potentially can lead to early detection of breast abnormalities. We propose to systematically chart literature and examine the scope of evidence on women's knowledge and practice of breast self-examination in sub-Saharan Africa (SSA).

METHODS

Our scoping review methods will be guided by the framework proposed by Arksey and O'Malley, Levac et al. and Joanna Briggs Institute guidelines. Literature searches will be conducted in the following electronic databases (from 2008 onwards): PubMed/MEDLINE, Scopus, Web of Science, CINAHL, PsycINFO and Health Sources. Grey literature will be identified through searching dissertation databases, Google Scholar and governmental databases. Two reviewers will screen all citations and full-text articles We will abstract data, organise them into themes and sub-themes, summarise them and report the results using a narrative synthesis. The study methodological quality (or bias) will be appraised using a mixed-method appraisal tool.

DISCUSSION

The findings from the scoping review will contribute to obtain an understanding of the women's knowledge and practice of breast self-examination in sub-Saharan Africa, and will likely reveal the depth of evidence helping to identify gaps for future research. Results will be published in a peer-reviewed journal. Implications for clinical practice and health policy will be discussed.

Pattern of Mammography Utilization by Women Attending Asokoro District Hospital, Abuja, Nigeria

Introduction:

Mammography is a major tool for the screening and diagnosis of breast cancer globally. Poor funding and lack of good public health education for mammography in resource-limited countries limit access to mammographic services. In these settings, patients bear the cost of breast cancer screening from out-of-pocket expenses. The aim of this study was to interrogate the pattern of utilization of mammography by women of childbearing age, who attended Asokoro District Hospital (ADH) for Healthcare, with the view to increase uptake.

Materials and Methods:

This was a 4-year retrospective, cross-sectional study of 534 women who attended ADH from July 2015 to June 2019 for screening or diagnostic mammography. Data were extracted from completed questionnaire by women who had mammography during the period under review. The data were entered into Statistical Package for the Social Sciences version 27 by IBM for analysis.

Results:

The mean age of the women was 47.8 years ± 7.7 with a range of 30–82 years. Most of the women, 525 (94.9%), were referred for mammography by health workers; only nine (5.1%) had mammography on self-referral. In all, 71% of the women paid for their mammography from their pockets, whereas 28.1% made payments through the National Health Insurance Scheme (NHIS). A total of 100% of women who reported for mammography on self-referral paid for the services from their pockets. The association between the funding options and mode of referral was statistically significant, P = 0.049.

Conclusion:

This study showed that referral for mammography by health workers was responsible for not only most of the mammograms conducted but also all the women who utilized NHIS to pay for this service. Resources should therefore be directed towards creating awareness among health workers, especially with the present level of NHIS coverage in the population, in order to increase the uptake of screening mammography in the population.

Correlation between a variable number tandem repeat (VNTR) polymorphism in SMYD3 gene and breast cancer: A genotype-phenotype study

Genetic predisposition to breast cancer (BC) has become one of the most studied aspects of the disease. Advances in the field of cancer research have revealed the role of different genetic polymorphisms within genes of interest in the development of BC. This study aimed to explore the impact of a variable number tandem repeat (VNTR) genetic variant found within the SET and MYND domain containing protein 3 (SMYD3) gene on BC risk in Jordan and examine key clinical and pathological prognostic factors. Genotyping of blood samples from 180 cases with breast cancer and 180 healthy individuals from the Jordanian population was carried out via a combination of PCR and agarose gel electrophoresis. A highly significant association was found at level of genotype (P-value = 0.009) and allele (P-value = 0.0001) between BC development and the VNTR variant in the SMYD3 gene among Jordanian women. Moreover, we found that the VNTR of SMYD3 gene may interfere with BC risk among patients with different immunohistochemistry (IHC) profiles (P-value < 0.05). This study reported that there is a significant correlation between BC development and the VNTR in the SMYD3 gene. These findings can help alleviate the burden of BC in developing countries including Jordan and to fill the gaps in current literature. Since this study was carried out on Jordanian Arabs, more studies on the link between BC and the SMYD3 VNTR variant are recommended to determine this polymorphism's impact on other ethnic groups.

Assessment and Improvement Strategies for a Breast Cancer Early Detection Program in Rural South Africa

Purpose To assess and develop solutions for an ultrasound-based breast cancer early detection program in rural South Africa 1 year after implementation. Methods A WHO-endorsed RAD-AID Radiology Readiness Assessment was used to evaluate clinic resources. In addition, 5 weeks of observation identified resource deficiencies and reviewed existing documentation methods. On the basis of stakeholders' input and the BI-RADS, we developed new documentation systems. Training was followed by a survey that assessed feasibility and provider acceptance. Results Resource limitations included lack of computers, unpredictable electrical supply, and inconsistent Internet. The assessment revealed incomplete documentation of breast clinical examinations and history, breast lesions, and follow-up. Furthermore, limitations negatively affected communication among providers. Three solutions were developed: a paper patient history form, a paper clinical findings form, and a computerized patient-tracking data base compliant with BI-RADS. Three nurses, three nursing assistants, and one counselor completed the survey. Seventy-one percent indicated positive general attitudes, and 100% agreed that the documentation system is easy and useful and improves overall quality of care, follow-up, decision making; access to clinical information; and communication between clinicians and patients. Five of the seven providers reported that the system increased visit time, but three of those five believed that the process was valuable. Conclusion Implementation of a breast cancer early detection program in resource-limited regions is challenging, and continual assessment is essential. As a result of identified needs, we developed a documentation system that was broadly accepted. Future steps should focus on increasing efficiency, evaluation of provider attitudes long term, and clinical effect.

Impact of Breast Cancer Early Detection Training on Rwandan Health Workers' Knowledge and Skills

Purpose

In April 2015, we initiated a training program to facilitate earlier diagnosis of breast cancer among women with breast symptoms in rural Rwanda. The goal of this study was to assess the impact of the training intervention in breast cancer detection on knowledge and skills among health center nurses and community health workers (CHWs).

Methods

We assessed nurses’ and CHWs’ knowledge about breast cancer risk factors, signs and symptoms, and treatability through a written test administered immediately before, immediately after, and 3 months after trainings. We assessed nurses’ skills in clinical breast examination immediately before and after trainings and then during ongoing mentorship by a nurse midwife. We also examined the appropriateness of referrals made to the hospital by health center nurses.

Results

Nurses’ and CHWs’ written test scores improved substantially after the trainings (overall percentage correct increased from 73.9% to 91.3% among nurses and from 75.0% to 93.8% among CHWs (P < .001 for both), and this improvement was sustained 3 months after the trainings. On checklists that assessed skills, nurses’ median percentage of actions performed correctly was 24% before the training. Nurses’ skills improved significantly after the training and were maintained during the mentorship period (the median score was 88% after training and during mentorship; P < .001). In total, 96.1% of patients seen for breast concerns at the project’s hospital-based clinic were deemed to have been appropriately referred.

Conclusion

Nurses and CHWs demonstrated substantially improved knowledge about breast cancer and skills in evaluating and managing breast concerns after brief trainings. With adequate training, mentorship, and established care delivery and referral systems, primary health care providers in sub-Saharan Africa can play a critical role in earlier detection of breast cancer.

The Structure and Parameterization of the Breast Cancer Transition Model Among Chinese Women

OBJECTIVES

Markov model simulation based on the natural history of disease is commonly employed for the comparative research of health interventions. The present study aims to simulate the natural progression of breast cancer and parameterize the initial and transition probabilities of multiple states of breast cancer development among Chinese women.

METHODS

The age-specific incidence, mortality, and clinical stage distribution of breast cancer; and relapse rate of each clinical stage were collected from China's cancer registry yearbooks and clinical epidemiological studies to simulate the process from full health to breast cancer to death among Chinese women aged 30 to 80 through a Markov cohort study. The validity analysis was conducted to evaluate the accuracy of the model estimation.

RESULTS

A Markov transition model with 7 states (no breast cancer, clinical stages 0-IV breast cancer, and death) was constructed for Chinese women. The age-specific incidence, mortality, and clinical stage distribution of breast cancer estimated by the initial and transition probabilities among different Markov states were highly consistent with the registered data and observed studies.

CONCLUSION

A breast cancer transition model for Chinese women has been established with validity. It could be a point of reference for further economic evaluations and breast cancer screening policy formulation.

Evaluation of Health Belief Model-Based Intervention on Breast Cancer Screening Behaviors among Health Volunteers

Breast cancer is the most common cancer and the second leading cause of death among women. Regarding the lack of knowledge about the cause of breast cancer and considering the fact that all women are prone to this disease, training on methods of early diagnosis to reduce its complications is of great importance. Thus, this study aimed to determine the effect of education based on the health belief model on breast cancer screening behaviors in health volunteers of health centers in Isfahan. In this experimental study, 480 healthy volunteers were randomly divided into two groups: the case (n = 240) and control (n = 240). The training program was designed according to health belief model structures. Before the training interventional program, the Champion standard questionnaire and functional checklist were completed for both groups. A standard questionnaire was completed during three stages (before, immediately after, and 2 months after the training). The experimental group received the educational intervention during eight sessions, and the collected data was eventually analyzed using the SPSS statistical software version 16 with relevant statistical tests. Participation of all individuals in the present research was voluntary and with informed consent. The results showed that mean scores of knowledge, perceived susceptibility, severity, benefits, barriers, self-efficacy, and behavioral intention related to breast self-examination (BSE) and mammography in the intervention group significantly increased compared with those of the control group immediately after and 2 months after educational intervention. There was a significant difference between groups in BSE skill 2 months after the intervention, but there was no significant difference between the two groups in BSE behavior and mammography 2 months after the intervention. The results confirmed the efficiency and effectiveness of an educational intervention based on the health belief model on improving factors affecting breast cancer screening behaviors.

Exploring breast cancer diagnosis and treatment experience among a sample of South African women who access primary health care

Despite the known impact of a cancer diagnosis and related treatments on quality of life, and the complexity of patient journeys in low-resource settings, there has been little published research into the relevant issues faced by South African women living with breast cancer. In this study, we aimed to understand the experiences of breast cancer diagnosis and treatment among a sample of South African women who access primary health care. A convenience sample of 12 women between the ages of 48 and 66 years attending a primary health care facility took part in our study. Women undergoing breast cancer treatment were invited to take part in face-to-face interviews. The interviews were semi-structured and guided by an interview schedule. Interviews were analysed thematically using ATLAS.ti v 8 computer software. We identified three important themes that explained how women experience diagnosis and treatment, namely, (1) reactions to the diagnosis experience, (2) the importance of faith, and (3) the value in having a sense of agency. Women’s initial reaction to their cancer diagnosis was one of shock and disbelief. Despite these reactions, faith and agency played an important role in how women in this study made sense of their illness experience and how they coped. Our findings demonstrate that women’s experiences of breast cancer diagnosis and treatment were accompanied by some psychological distress for which they need support. Furthermore, supporting women to make positive choices about coping and valuing the role of religion when appropriate should form part of any therapeutic engagement, medical or otherwise.

DNA Methylation Markers for Breast Cancer Detection in the Developing World

PURPOSE

An unmet need in low-resource countries is an automated breast cancer detection assay to prioritize women who should undergo core breast biopsy and pathologic review. Therefore, we sought to identify and validate a panel of methylated DNA markers to discriminate between cancer and benign breast lesions using cells obtained by fine-needle aspiration (FNA).Experimental Design: Two case-control studies were conducted comparing cancer and benign breast tissue identified from clinical repositories in the United States, China, and South Africa for marker selection/training (N = 226) and testing (N = 246). Twenty-five methylated markers were assayed by Quantitative Multiplex-Methylation-Specific PCR (QM-MSP) to select and test a cancer-specific panel. Next, a pilot study was conducted on archival FNAs (49 benign, 24 invasive) from women with mammographically suspicious lesions using a newly developed, 5-hour, quantitative, automated cartridge system. We calculated sensitivity, specificity, and area under the receiver-operating characteristic curve (AUC) compared with histopathology for the marker panel.

RESULTS

In the discovery cohort, 10 of 25 markers were selected that were highly methylated in breast cancer compared with benign tissues by QM-MSP. In the independent test cohort, this panel yielded an AUC of 0.937 (95% CI = 0.900-0.970). In the FNA pilot, we achieved an AUC of 0.960 (95% CI = 0.883-1.0) using the automated cartridge system.

CONCLUSIONS

We developed and piloted a fast and accurate methylation marker-based automated cartridge system to detect breast cancer in FNA samples. This quick ancillary test has the potential to prioritize cancer over benign tissues for expedited pathologic evaluation in poorly resourced countries.

Modifiable patient-related barriers and their association with breast cancer detection practices among Ugandan women without a diagnosis of breast cancer

Most women with breast cancer in sub-Saharan Africa (SSA) are diagnosed with late-staged disease. The current study assesses patient-related barriers among women from a general SSA population to better understand how patient-related barriers contribute to diagnostic delays. Using convenience-based sampling, 401 Ugandan women without breast cancer were surveyed to determine how prior participation in cancer detection practices correlate with patient-related barriers to prompt diagnosis. In a predominantly poor (76%) and rural population (75%), the median age of the participants was 38. Of the women surveyed, 155 (46%) had prior exposure to breast cancer education, 92 (27%) performed breast self-examination (BSE) and 68 (20%) had undergone a recent clinical breast examination (CBE), breast ultrasound or breast biopsy. The most commonly identified barriers to prompt diagnosis were knowledge deficits regarding early diagnosis (79%), economic barriers to accessing care (68%), fear (37%) and poor social support (24%). However, only women who reported knowledge deficits-a modifiable barrier-were less likely to participate in cancer detection practices (p<0.05). Women in urban and rural areas were similarly likely to report economic barriers, knowledge deficits and/or poor social support, but rural women were less likely than urban women to have received breast cancer education and/or perform BSE (p<0.001). Women who have had prior breast cancer education (p<0.001) and/or who perform BSE (p = 0.02) were more likely to know where she can go to receive a diagnostic breast evaluation. These findings suggest that SSA countries developing early breast cancer detection programs should specifically address modifiable knowledge deficits among women less likely to achieve a diagnostic work-up to reduce diagnostic delays and improve breast cancer outcomes.

Low Breast Conserving Surgery (BCS) rates in public hospitals in Malaysia: The effect of stage and ethnicity

INTRODUCTION

Breast-conserving surgery (BCS) with radiation therapy is the procedure of choice for early-stage breast cancer. Survival and locoregional recurrence is non-inferior to mastectomy, with superior cosmetic and psycho-social outcomes. Differing health systems have demonstrated a wide variation in the rate of BCS. Little is known about the rate of BCS and factors influencing its practice in middle resource countries. This study aims to examine the BCS rates in Malaysia and to identify factors influencing its uptake.

METHODOLOGY

This is a multi-centre, cross-sectional study involving the University of Malaya Medical Centre (UMMC), Queen Elizabeth II Hospital (QEH), and Tengku Ampuan Rahimah Hospital (TARH). Patients diagnosed with invasive breast cancer from January 2014 to December 2015 were included, excluding stromal cancers and lymphomas. Univariate and multivariate analyses identified factors influencing BCS.

RESULTS

A total of 1005 patients were diagnosed with breast cancer in the allocated time frame. Excluding incomplete records and those who did not have surgery, 730 patients were analysed. Overall BCS rate was 32.9%. The BCS rate was highest at QEH (54.1%), followed by UMMC (29.5%), and TARH (17.4%). 16.9% had BCS after neoadjuvant therapy. Factors influencing BCS uptake included age, ethnic group, breast-surgeon led services, AJCC Stage, tumour size, HER-2 expression, and tumour grade.

CONCLUSIONS

The rate of BCS in Malaysia is low. A wide variation of rate exists among the studied hospitals. Younger age, earlier AJCC stage, and the presence of a Breast sub-specialist surgeon, would make it more likely that the patient has her breast conserved.

Downstaging in opportunistic breast cancer screening in Brazil: a temporal trend analysis

BACKGROUND

Breast cancer is the most common female cancer in Brazil with an estimated 60 thousand new cases per year. Widespread use of mammography opportunistic screening has been observed in the last 20 years, including women under 50 years old. The present study aimed to analyse the trends in breast cancer stage distribution at diagnosis as a function of age in the study period.

METHODS

This paper examined temporal trends of stage distribution in women with breast cancer diagnosed between 2000 and 2015 in São Paulo state, Brazil. Data from the Hospital Cancer Registry of the region were utilized. Completeness was high. The sample was described according to age, stage and date of diagnosis using absolute frequency and proportions (%). For trends, the Cochran-Armitage test was used with a 5% level of significance (P-value< 0.05).

RESULTS

A total of 93,674 women were included in the analysis with a median age of 56 years old. One-third (34.4%) of the women were younger than 50 years old, and stage II was the most frequent stage (36.4%), even when analysed by age groups. Stage 0 corresponded to 7.7% (7247 women) of cases. In the study period, there was a significant trend towards an increase in Stages 0, I and IV (P < 0.01) and a trend towards a decrease in Stages IIA, IIB and IIIB (P < 0.001). Stage IIA was more prevalent until 2009, and stage I was more prevalent thereafter. The trends to increase the proportion of Stages 0 and I and to decrease the proportion of stages IIA, IIB and IIIB were significant in all age groups.

CONCLUSIONS

Breast cancer cases are diagnosed mainly at early stages, and approximately one-third of cases are younger than 50 years old. Downstaging has been shown. Opportunistic screening may have supported these results. Further studies are needed to show whether these results will impact the prognosis.
