Breast cancer survival in Ethiopia: a cohort study of 1,070 women

Willingness and ability to pay for breast cancer treatment among patients from Addis Ababa, Ethiopia: A cross-sectional study

INTRODUCTION

Breast cancer (BC) is the most common malignant neoplasm among women in Addis Ababa, Ethiopia. The willingness and ability to pay (WATP) for treatment is a contributing factor in the utilization of health care services. The World Health Organization Breast Cancer Initiative calls for 80% of patients to complete multimodality treatment and indicates payment as central factor to improve BC outcome. The objectives of this study are to identify how much female BC patients paid in Addis Ababa for BC treatment, their WATP for BC treatment, and the factors that affect WATP.

METHODS

The researchers collected data from 204 randomly selected BC patients who were treated in one of four different health facilities (one public and three private) between September 2018 and May 2019. A structured questionnaire was used to assess their WATP for BC treatment and multivariable regression to investigate factors associated with patients' WATP.

RESULTS

Of interviewed patients, 146 (72%) were at reproductive age. Patients' median expenditure for all BC treatment services was 336 US dollars (USD) in a public cancer center and 926 USD in privately owned health facilities. These amounts are in contrast with a reported WATP of 50 USD and 149 USD. WATP increased with increasing expenditure (OR 1.43; 95% CI 1.09 to 1.89 per 100 US), educational level (OR 1.37; 95% CI 1.02 to 1.85) and service quality (OR 1.34; 95% CI 1.04 to 1.72). In contrast, a monthly income increase by 100 USD corresponds to a 17% decrease of WATP (OR 0.83; 95% CI 0.70 to 0.99).

CONCLUSIONS

We demonstrated that BC treatment was very expensive for patients, and the cost was much higher than their WATP. Thus, we suggest that BC should be included in both social and community-based health insurance plans and treatment fees should consider patients' WATP.

Assessing the survival time of women with breast cancer in Northwestern Ethiopia: using the Bayesian approach

BACKGROUND

Despite the significant weight of difficulty, Ethiopia's survival rate and mortality predictors have not yet been identified. Finding out what influences outpatient breast cancer patients' survival time was the major goal of this study.

METHODS

A retrospective study was conducted on outpatients with breast cancer. In order to accomplish the goal, 382 outpatients with breast cancer were included in the study using information obtained from the medical records of patients registered at the University of Gondar referral hospital in Gondar, Ethiopia, between May 15, 2016, and May 15, 2020. In order to compare survival functions, Kaplan-Meier plots and the log-rank test were used. The Cox-PH model and Bayesian parametric survival models were then used to examine the survival time of breast cancer outpatients. The use of integrated layered Laplace approximation techniques has been made.

RESULTS

The study included 382 outpatients with breast cancer in total, and 148 (38.7%) patients died. 42 months was the estimated median patient survival time. The Bayesian Weibull accelerated failure time model was determined to be suitable using model selection criteria. Stage, grade 2, 3, and 4, co-morbid, histological type, FIGO stage, chemotherapy, metastatic number 1, 2, and >=3, and tumour size all have a sizable impact on the survival time of outpatients with breast cancer, according to the results of this model. The breast cancer outpatient survival time was correctly predicted by the Bayesian Weibull accelerated failure time model.

CONCLUSIONS

Compared to high- and middle-income countries, the overall survival rate was lower. Notable variables influencing the length of survival following a breast cancer diagnosis were weight loss, invasive medullar histology, comorbid disease, a large tumour size, an increase in metastases, an increase in the International Federation of Gynaecologists and Obstetricians stage, an increase in grade, lymphatic vascular space invasion, positive regional nodes, and late stages of cancer. The authors advise that it is preferable to increase the number of early screening programmes and treatment centres for breast cancer and to work with the public media to raise knowledge of the disease's prevention, screening, and treatment choices.

Development, acceptability and usability of culturally appropriate survivor narrative videos for breast cancer treatment in Botswana: a pilot study

OBJECTIVES

Narrative communication has demonstrated effectiveness in promoting positive health behaviours, delivering support and coping with complex decision-making. Formal research evaluating this intervention for cancer treatment in Africa is lacking. We aimed to develop, and assess acceptability and usability of survivor video narrative interventions for breast cancer treatment in Botswana.

DESIGN

A pilot study design.

SETTING

Single-centre, tertiary hospital, sub-Saharan Africa.

PARTICIPANTS

Eight women, ≥18 years old, with stages I-III breast cancer were enrolled for the video intervention. 106 women, ≥18 years old, with stages I-IV breast cancer viewed the narrative videos and 98 completed the acceptability and usability surveys.

INTERVENTION

Survivor narrative videos were developed using the theory of planned behaviour and using a purposive sample of Batswana, Setswana-speaking, breast cancer survivors, who had completed systemic treatment and surgery with high rates of adherence to the prescribed treatment plan.

PRIMARY OUTCOMES

We assessed acceptability and usability among prospectively enrolled patients presenting for routine breast cancer care at Princess Marina Hospital in Botswana, using a 13-item survey.

RESULTS

Participants expressed high acceptability and usability of the videos, including 99% (97/98) who strongly agreed/agreed that the video presentations were easy to understand, 92% (90/98) who would recommend to other survivors and 94% (92/98) who wished there were more videos. Additionally, 89% (87/98) agreed or strongly agreed that the one-on-one instruction on how to use the tablet was helpful and 87% (85/98) that the video player was easy to use.

CONCLUSION

Culturally appropriate survivor video narratives have high acceptability and usability among patients with breast cancer in Botswana. There is an opportunity to leverage this intervention in routine breast cancer care for treatment support. Future studies will test the implementation and effectiveness of narrative videos on a wider scale, including for patients being treated for other cancers.

Human Breast Tissue Microbiota Reveals Unique Microbial Signatures that Correlate with Prognostic Features in Adult Ethiopian Women with Breast Cancer

Breast cancer (BC) is the leading cause of cancer mortality among women in Ethiopia. Overall, women of African ancestry have the highest death toll due to BC compared to other racial/ethnic groups. The cause of the disparity in mortality is unclear. Recently, studies conducted in the United States and other high-income countries highlighted the role of microbial dysbiosis in BC initiation, tumor growth, and treatment outcome. However, the extent to which inter-individual differences in the makeup of microbiota are associated with clinical and histopathological outcomes in Ethiopian women has not been studied. The goal of our study was to profile the microbiome in breast tumor and normal adjacent to tumor (NAT) tissues of the same donor and to identify associations between microbial composition and abundance and clinicopathological factors in Ethiopian women with BC. We identified 14 microbiota genera in breast tumor tissues that were distinct from NAT tissues, of which Sphingobium, Anaerococcus, Corynebacterium, Delftia, and Enhydrobacter were most significantly decreased in breast tumors compared to NAT tissues. Several microbial genera significantly differed by clinicopathological factors in Ethiopian women with BC. Specifically, the genus Burkholderia more strongly correlated with aggressive triple negative (TNBC) and basal-like breast tumors. The genera Alkanindiges, Anoxybacillus, Leifsonia, and Exiguobacterium most strongly correlated with HER2-E tumors. Luminal A and luminal B tumors also correlated with Anoxybacillus but not as strongly as HER2-E tumors. A relatively higher abundance of the genus Citrobacter most significantly correlated with advanced-stage breast tumors compared to early-stage tumors. This is the first study to report an association between breast microbial dysbiosis and clinicopathological factors in Ethiopian women.

Nutritional status and quality of life among breast Cancer patients undergoing treatment in Addis Ababa, Ethiopia

BACKGROUND

The prevalence of malnutrition in cancer patients ranges from 30 to 60%. While it is known that malnutrition is prevalent among cancer patients, the relationship between undernutrition and quality of life among breast cancer patients has not been adequately explored. Therefore, the present study was aimed at assessing the association between undernutrition and quality of life among Breast Cancer patients under treatment in Addis Ababa, Ethiopia.

METHODS

A cross-sectional study on breast cancer patients under treatment at the outpatient and in-patient departments of oncology centers of two tertiary hospitals in Addis Ababa - Tikur Anbessa Specialized Hospital (TASH) and St. Paul Millennium Medical College (SPHMMC) oncology was conducted from May 12 to August 26,2020. Nutritional status was assessed using Subjective Global Assessment (SGA) screening tool. Quality of life was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Cancer 30 (EORTC QLQ C30) a standard quality of life measurement scale for cancer patients. To determine the relationship between quality of life scores and nutritional status multivariable linear regression was fitted.

RESULTS

A total of 411 breast cancer patients with mean age of 44.4 (± 11.47) years. And 393 (95.6%) of them female were included in the study. A high prevalence of moderate 127 (30.9%) and severe 106 (25.8%) malnutrition was observed. Moderate (β = -9.21 CI (- 14.59, - 4.67)) and severe (β = -17.81 CI (- 16.6, 2 - 2.91)) malnutrition were negatively associated with the overall quality of life. Malnutrition also showed negative associations with all domains of functional status (P < 0.05) and strong positive associations with symptom scores covered in the EORTC QLQ C-30 (P < 0.05).

CONCLUSION

This study indicated that malnutrition is a major problem among breast cancer patients and the nutritional status breast cancer patients was related to their quality of life….

Clinicopathological Features of Invasive Breast Cancer: A Five-Year Retrospective Study in Southern and South-Western Ethiopia

Background: Breast cancer (BC) is the most common type of cancer in Ethiopia. The incidence of BC is also rising, but the exact figure is still poorly known. Therefore, this study was conducted to address the gap in epidemiological data on BC in southern and southwestern Ethiopia. Materials and Methods: This is a five-year (2015-2019) retrospective study. The demographic and clinicopathological data were collected from biopsy reports of different kinds of breast carcinomas in the pathology department of Jimma University Specialized Hospital and Hawassa University Specialized Referral Hospital. Histopathological grades and stages were conducted using Nottingham grading and TNM staging system, respectively. Collected data were entered and analyzed using SPSS Version-20 software. Results: The mean age of patients at diagnosis was 42.27 (SD = 13.57) years. The pathological stage of most BC patients was stage III, and most of them had tumor sizes greater than 5 cm. Most patients had moderately differentiated tumor grade, and mastectomy was the most common type of surgery at the time of diagnosis. Invasive ductal carcinoma was the most common histological type of BC, followed by invasive lobular carcinoma. Lymph node involvement was seen in 60.5% of cases. Lymph node involvement was associated with tumor size (χ² = 8.55, p = 0.033) and type of surgery (χ² = 39.69, p < 0.001). Conclusions: This study showed that BC patients in southern and southwestern Ethiopia displayed advanced pathological stages, relatively young age at diagnosis, and predominant invasive ductal carcinoma histological patterns.

Survival and predictors of breast cancer mortality in South Ethiopia: A retrospective cohort study

BACKGROUND

Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death in over 100 countries. In March 2021, the World Health Organization called on the global community to decrease mortality by 2.5% per year. Despite the high burden of the disease, the survival status and the predictors for mortality are not yet fully determined in many countries in Sub-Saharan Africa, including Ethiopia. Here, we report the survival status and predictors of mortality among breast cancer patients in South Ethiopia as crucial baseline data to be used for the design and monitoring of interventions to improve early detection, diagnosis, and treatment capacity.

METHODS

A hospital-based retrospective cohort study was conducted among 302 female breast cancer patients diagnosed from 2013 to 2018 by reviewing their medical records and telephone interviews. The median survival time was estimated using the Kaplan-Meier survival analysis method. A log-rank test was used to compare the observed differences in survival time among different groups. The Cox proportional hazards regression model was used to identify predictors of mortality. Results are presented using the crude and adjusted as hazard ratios along with their corresponding 95% confidence intervals. Sensitivity analysis was performed with the assumption that loss to follow-up patients might die 3 months after the last hospital visit.

RESULTS

The study participants were followed for a total of 4,685.62 person-months. The median survival time was 50.81 months, which declined to 30.57 months in the worst-case analysis. About 83.4% of patients had advanced-stage disease at presentation. The overall survival probability of patients at two and three years was 73.2% and 63.0% respectively. Independent predictors of mortality were: patients residing in rural areas (adjusted hazard ratio = 2.71, 95% CI: 1.44, 5.09), travel time to a health facility ≥7 hours (adjusted hazard ratio = 3.42, 95% CI: 1.05, 11.10), those who presented within 7-23 months after the onset of symptoms (adjusted hazard ratio = 2.63, 95% CI: 1.22, 5.64), those who presented more than 23 months after the onset of symptoms (adjusted hazard ratio = 2.37, 95% CI: 1.00, 5.59), advanced stage at presentation (adjusted hazard ratio = 3.01, 95% CI: 1.05, 8.59), and patients who never received chemotherapy (adjusted hazard ratio = 6.69, 95% CI: 2.20, 20.30).

CONCLUSION

Beyond three years after diagnosis, patients from southern Ethiopia had a survival rate of less than 60% despite treatment at a tertiary health facility. It is imperative to improve the early detection, diagnosis, and treatment capacities for breast cancer patients to prevent premature death in these women.

Survival analysis of women breast cancer patients in Northwest Amhara, Ethiopia

Introduction

Breast cancer, the most common cause of cancer death and the most frequently diagnosed cancer among women worldwide, ranks as the second cause of death next to lung cancer. Thus, the main objective was to assess the factors that affect the survival time of breast cancer patients using the shared frailty model.

Methods

A retrospective study design was used to collect relevant data on the survival time of breast cancer patients from the medical charts of 322 breast cancer patients under follow-up at the Felege Hiwot Comprehensive Specialized Hospital (FHCSH). The data were explored using the Cox proportional hazard model, the accelerated failure time model, and shared frailty models. The model comparison was done using AIC and BIC. As a result, the Weibull gamma shared frailty model had a minimum AIC and BIC value.

Result

From a total of 322 patients, about 95 (29.5%) died and 227 (70.5%) were censored. The overall mean and median estimated survival times of breast cancer patients under study were 43.7 and 45 months, respectively. The unobserved heterogeneity in the population of clusters (residence) as estimated by the Weibull-gamma shared frailty model was 0.002 (p-value = 0.000), indicating the presence of residential variation in the survival time of breast cancer patients. The estimated hazard rate of patients who had not had recurrent breast cancer was 0.724 (95% CI: 0.571, 0.917) times the estimated hazard rate of patients who had had recurrent breast cancer.

Conclusion

The prevalence of breast cancer was considerably high. Under this investigation, older patients, patients in stages III and IV, anemic and diabetes patients, patients who took only chemotherapy treatment, metastasized patients, patients with an AB blood type, patients with a positive breast cancer family history, and patients whose cancer was recurrent had high death rates. Patient characteristics such as age, stage, complications, treatment, metastasis, blood type, family history, and recurrence were significant factors associated with the survival time of women with breast cancer.

Health system cost of breast cancer treatment in Addis Ababa, Ethiopia

BACKGROUND

Breast cancer is the leading cancer among women with an annual crude incidence of 27.4 per 100,000 in Ethiopia. The aims of this study were to (a) estimate the unit cost of breast cancer treatment for the standard Ethiopian patient, (b) identify the cost drivers, (c) project the total cost of breast cancer treatment for the next five years, and (d) estimate the economic burden of the disease in the main specialized tertiary hospital-Tikur Anbessa Specialized Hospital (TASH) Addis Ababa.

METHODS

Primary data were collected from health and non-health professionals. Secondary data were collected from patient`s charts and official reports from various national and international organisations including data from TASH. To establish work-time estimates, we asked professionals on their time usage.

RESULT

A total of US$ 33,261 was incurred to treat 52 Addis Ababa resident female breast cancer patients in TASH between July 2017 and June 2019. The unit cost of treatment for a hypothetical breast cancer patient to complete her treatment was US$ 536 for stage I and US$ 705 for stage II and III using the existing infrastructure. This cost increased to US$ 955 for stage I and US$ 1157 for stage II and III when infrastructure amortization was considered. The projected total costs of breast cancer treatment in TASH is between US$ 540,000 and US$ 1.48million. However, this will increase to US$ 870,000 and US$ 2.29 million when the existing fixed assets are changed.

CONCLUSION

The economic burden of breast cancer treatment is high compared to the economic status of the country. Thus, it is recommended that TASH should revise its charges and breast cancer should be included in the Social and Community based health insurance scheme. JEL classification: H51, H75, I18, P46.

Early onset, delayed diagnosis and laterality of breast carcinoma: Evidence from a tertiary care hospital

Objectives:

To assess age at onset, delayed diagnosis and laterality of breast carcinoma among women at Debre Markos Comprehensive Specialized Hospital, North West Ethiopia.

Methods:

Hospital-based descriptive study was conducted on 120 breast carcinoma cases at pathology department of Debre Markos Comprehensive Specialized Hospital, from October 2019 to December 2021. The women aware of symptoms until first medical consultation time was asked. The height and weight of the women were measured using the height and weight scale. The attending physician examined both breasts and regional lymph nodes. Pathological features of breast carcinomas were recorded when biopsy results arrived at the pathology department. Data were entered in Epi data version 3.1. Then, it was exported to SPSS version 25.0 statistical software for analysis.

Results:

Mean age of women was 39.9 ± 11.6 years, and median age was 38 years. Most women, 87 (72.5%) were aged less than 46 years. One hundred three (85.8%) women had complained breast lump pain for greater than 3 months before diagnosis. About 61 (50.8%) women had left breast carcinomas; 44 (36.7%) had right breast carcinomas and 15 (12.5%) had bilateral breast carcinomas. Of total, 53 (44.2%) cases were invasive ductal carcinomas; 41 (34.2%) had ductal carcinoma in situ; 14 (11.7%) were invasive lobular carcinomas; 8 (6.7%) were lobular carcinoma in situ and only 4 (3.3%) cases were mixed carcinomas.

Conclusion:

In this study, about two-third of the cases had early onset breast carcinoma. Most of the cases had delayed diagnosis of breast carcinoma. More than half of the cases had left breast carcinoma.

Knowledge on risk factors and practice of early detection methods of breast cancer among graduating students of Debre Tabor University, Northcentral Ethiopia

Background

Breast cancer is the greatest common cancer in women worldwide, with approximately 1.7 million new cases diagnosed each year in the world which accounts for 12% of all new cancer cases and 25% of all cancers in women. Even though the higher mortality rate of breast cancer in low and middle-income countries, the practice of early detection methods is low and the majority of the patients who appeared at an advanced stage of the disease need palliative care with little survival rates. However, evidence is scarce on the knowledge and practice of breast cancer early detection methods among women of reproductive age in Ethiopia. Therefore we aimed to assess the knowledge on risk factors and practice of early detection methods of breast cancer among female graduating students of Debre Tabor University.

Methods

Institution-based cross-sectional study was conducted. A stratified random sampling technique was used. Data were collected with a self-administer questionnaire. The collected data were processed and analyzed with the computer using SPSS version 25 software. Descriptive statistics were used to describe the socio-demographic information of participants. Binary and multivariable logistic regression with an adjusted odds ratio (AOR) and 95% confidence interval (CI) was used to identify factors associated with the outcome variable. Statistical significance was stated at p < 0.05.

Result

A total of 270 female students participated in the study. The median age (± SD) was 24.63 years (± 1.26). All of the students heard about breast cancer and early detection methods. About 206 (76.67%) of the participants had good knowledge of breast self-examination. Mass media, health professionals, and friends in combination were the main source of information 172 (63.77%), only 110 (40.70%) of students performed a breast-self-examination and the rest did not perform it due to forgetting fullness and lack of knowledge. About 208 (77.1%) of the respondents respond family history is a risk factor for breast cancer. Being a health science student (AOR = 2.32; 95% CI: 2.12, 3.52), family history of breast problems (AOR = 3.41; 95% CI: 3.22, 8.33), and having a good level of knowledge (AOR = 1.83; 95% CI: 1.01, 5.68) were the factors associated with the practice of breast self-examination.

Conclusion

Most of the participants were unaware of the benefits, appropriate timing, and techniques of doing a breast self-examination. Health science students had better awareness & practice of breast self-examination than non-health science students. Trained health professionals must give focus on giving health information regarding risk factors of breast cancer and methods of early detection of breast cancer to the public & their clients.

The Impact of Breast Cancer Treatment Delays on Survival Among South African Women

BACKGROUND

In high-income settings, delays from breast cancer (BC) diagnosis to initial treatment worsen overall survival (OS). We examined how time to BC treatment initiation (TTI) impacts OS in South Africa (SA).

METHODS

We evaluated women enrolled in the South African BC and HIV Outcomes study between July 1, 2015 and June 30, 2019, selecting women with stages I-III BC who received surgery and chemotherapy. We constructed a linear regression model estimating the impact of sociodemographic and clinical factors on TTI and separate multivariable Cox proportional hazard models by first treatment (surgery and neoadjuvant chemotherapy (NAC)) assessing the effect of TTI (in 30-day increments) on OS.

RESULTS

Of 1260 women, 45.6% had upfront surgery, 54.4% had NAC, and 19.5% initiated treatment >90 days after BC diagnosis. Compared to the surgery group, more women in the NAC group had stage III BC (34.8% vs 81.5%). Living further away from a hospital and having hormone receptor positive (vs negative) BC was associated with longer TTI (8 additional days per 100 km, P = .003 and 8 additional days, P = .01, respectively), while Ki67 proliferation index >20 and upfront surgery (vs NAC) was associated with shorter TTI (12 and 9 days earlier; P = .0001 and.007, respectively). Treatment initiation also differed among treating hospitals (P < .0001). Additional 30-day treatment delays were associated with worse survival in the surgery group (HR 1.11 [95%CI 1.003-1.22]), but not in the NAC group.

CONCLUSIONS

Delays in BC treatment initiation are common in SA public hospitals and are associated with worse survival among women treated with upfront surgery.

Intrinsic subtypes in Ethiopian breast cancer patient

PURPOSE

The recent development of multi-gene assays for gene expression profiling has contributed significantly to the understanding of the clinically and biologically heterogeneous breast cancer (BC) disease. PAM50 is one of these assays used to stratify BC patients and individualize treatment. The present study was conducted to characterize PAM50-based intrinsic subtypes among Ethiopian BC patients.

PATIENTS AND METHODS

Formalin-fixed paraffin-embedded tissues were collected from 334 BC patients who attended five different Ethiopian health facilities. All samples were assessed using the PAM50 algorithm for intrinsic subtyping.

RESULTS

The tumor samples were classified into PAM50 intrinsic subtypes as follows: 104 samples (31.1%) were luminal A, 91 samples (27.2%) were luminal B, 62 samples (18.6%) were HER2-enriched and 77 samples (23.1%) were basal-like. The intrinsic subtypes were found to be associated with clinical and histopathological parameters such as steroid hormone receptor status, HER2 status, Ki-67 proliferation index and tumor differentiation, but not with age, tumor size or histological type. An immunohistochemistry-based classification of tumors (IHC groups) was found to correlate with intrinsic subtypes.

CONCLUSION

The distribution of the intrinsic subtypes confirms previous immunohistochemistry-based studies from Ethiopia showing potentially endocrine-sensitive tumors in more than half of the patients. Health workers in primary or secondary level health care facilities can be trained to offer endocrine therapy to improve breast cancer care. Additionally, the findings indicate that PAM50-based classification offers a robust method for the molecular classification of tumors in the Ethiopian context.

OUP accepted manuscript

Introduction

Many women in rural Ethiopia do not receive adjuvant therapy following breast cancer surgery despite the majority being diagnosed with estrogen-receptor-positive breast cancer and tamoxifen being available in the country. We aimed to compare a breast nurse intervention to improve adherence to tamoxifen therapy for breast cancer patients.

Methods and Materials

The 8 hospitals were randomized to intervention and control sites. Between February 2018 and December 2019, patients with breast cancer were recruited after their initial surgery. The primary outcome of the study was adherence to tamoxifen therapy by evaluating 12-month medication-refill data with medication possession ratio (MPR) and using a simplified medication adherence scale (SMAQ) in a subjective assessment.

Results

A total of 162 patients were recruited (87 intervention and 75 control). Trained nurses delivered education and provided literacy material, gave additional empathetic counselling, phone call reminders, and monitoring of medication refill at the intervention hospitals. Adherence according to MPR at 12 months was high in both the intervention (90%) and control sites (79.3%) (P = .302). The SMAQ revealed that adherence at intervention sites was 70% compared with 44.8% in the control sites (P = .036) at 12 months. Persistence to therapy was found to be 91.2% in the intervention and 77.8% in the control sites during the one-year period (P = .010).

Conclusion

Breast nurses can improve cost-effective endocrine therapy adherence at peripheral hospitals in low-resource settings. We recommend such task sharing to overcome the shortage of oncologists and distances to central cancer centers.

Epidemiological Trends of Breast Cancer in Southern Ethiopia: A Seven-Year Retrospective Review

INTRODUCTION

African women are affected by cancer at an early age of their productivity. However, the exact prevalence and incidence of cancer, including breast cancer is not known in most sub-Saharan African countries, including Ethiopia because of lack of well-established cancer registry. This study aims to assess the epidemiology of breast cancer at Hawassa University Comprehensive Specialized Hospital (HUCSH), the biggest referral hospital with cancer treatment center serving the southern part of the country.

METHODS

Retrospective review of charts of all patients with a diagnosis of breast cancer between 2013 and 2019 at HUCSH was conducted. A standardized questionnaire was used to collect relevant data that include sociodemographic, symptoms, type of diagnosis, treatment, and outcomes. Data were entered using epidata version 3.1 and analyzed using MS Excel and SPSS version 20.

RESULTS

Five hundred fifty-nine (18.6%) breast cancer cases were retrieved in 7 years between 2013 and 2019. Of this, 548 (98%) were women. The median ages of the patents were 38 years. Invasive ductal carcinoma was the leading 309 (55.3%) histologic type followed by 185 (33.1%) lobular carcinoma. One hundred seventy-seven (31.7%) were moderately differentiated and 155 (27.7%) were poorly differentiated. Three hundred seventy-two (66.5%) were advanced breast cancer (Stages III and IV). Trends of breast cancer showed the case load is continuously increasing except with a slight reduction of cases in between 2015 and 2016. The majority were advanced breast cancer occurring at an early age by the time diagnosis made. Invasive ductal carcinomas were the predominant one. The trend also showed a continuous increment of cancer case load. Therefore, cancer registration center establishment, community awareness creation, and intensive early detection strategy are mandatory.

Survival and Predictors of Mortality among Breast Cancer Patients in Northwest Ethiopia: A Retrospective Cohort Study

BACKGROUND

Breast cancer is the most common malignant tumor and the leading cause of cancer death in over 100 countries. Despite the high burden of difficulty, the survival status and the predictors for mortality are not yet determined in Ethiopia. Studies related to this area are scarce. Therefore, we aimed to estimate the survival status and predictors of mortality among breast cancer patients in Northwest Ethiopia.

METHODS

A retrospective cohort study design was carried out from September 2015 to August 2020 among 482 women who had breast cancer in Northwest Ethiopia. A systematic sampling technique was employed to select the required representative sample. The Cox regression model was used to identify the predictors of mortality among breast cancer patients.

RESULTS

For this study, 482 participants had followed for 8824 person-months total analysis time or at-risk time. In our findings, the overall survival of breast cancer patients at the end of two and five years was 54.24% and 25.8%, respectively. In the multivariable Cox regression model, age, stage of BC, menopausal status, and surgical therapy were significant predictors of death.

CONCLUSION

The overall survival after two years was 54.24%, and after five years was 25.8%. This result is lower than the recently published report and indicates that in LMIC, especially in rural cancer centers, the infrastructure and resources for routine screening mammography are often unavailable. Therefore, there is a need to promote early diagnosis of BC at each level of health-care delivery point.

Female breast cancer in sub-Saharan Africa: A PRISMA-S-compliant systematic review of surgery

BACKGROUND

In sub-Saharan countries (SSAs), the advanced stage at diagnosis and the limited surgical interventions of female breast cancer (FBC) lead to poor outcomes. This study assessed current modalities of FBC surgeries.

METHODS

Six literature databases (Medline, Embase, African Journal Online, Google Scholar, Web of Science, Cochrane Library) were searched, plus a manual search, in 2011-2021. We included primary data studies with any setting and presurgeries or postsurgeries treatments, we excluded non-English language studies, editorials, and grey literature.

RESULTS

The search yielded 21 observational studies (16 retrospective, 3 prospective, and 2 case reports). Of the total 6900 patients, 4121 (60%) patients underwent FBC surgical excision only, and 751/2779 (27%) conservative surgery (BCS) or therapy (BCT). All studies reported similar use of mastectomy (>60%), the FBC surgical excision/reconstruction studies displayed more neoadjuvant chemotherapy (536/2779, 19% vs. 215/4121, 5%), and radiotherapy or adjuvant radiotherapy (1461/2779, 52% vs. 411/3921, 4%). Patients' age, histological classification, staging, and follow-up data were often missing.

CONCLUSIONS

The FBC complexity requires structured management by general and plastic surgeons, radiotherapy specialists, and obstetrician-gynecologists through shared guidelines, protocols, and specific programs of public health. In SSAs, FBC surgical strategies should point at decreasing radical mastectomy and increasing BCS/BCT.

Cost-effectiveness of screening mammography in a low income country: a Markov simulation analysis

Background

Breast cancer is the most common cancer diagnosed in women. Screening mammography is the only imaging screening study for breast cancer with a proven. mortality benefit. This study aims to analyze the cost-effectiveness of screening mammography in Ethiopia.

Methods

Multistate Markov model was used for computer simulation to estimate cost and health benefits of screening mammography interventions for age-group of 40–49 years and 50–59 years. The cost-effectiveness analysis was made for 4 policies based on where the screening mammography procedures were conducted: government institution only, the private institution only, 50% ratio for each, and 10% private institution policy. Outputs were expressed in total cost, life-years gained (LYG) incremental cost-effectiveness ratio (ICER), and incremental net monetary benefit (INMB).

Results

All 4 policies of annual screening mammography failed to achieve acceptable ICER and lead to a net loss in INMB. The lowest ICER value was for government institution-only policy with 3510.3 USD/LYG and 3224.9 USD/LYG both above the cost-effectiveness threshold of 2808.5 USD. The cost per single death averted for each group was 110,206.7 USD and 77,088.2 USD for age-group 40–49 years and 50–59 years respectively.

Conclusion

Screening mammography could not be shown to be cost-effective in Ethiopia with the current low cost-effectiveness threshold. Alternative screening approach like annual clinical breast examination may need to be investigated.

Adherence to Newly Implemented Tamoxifen Therapy for Breast Cancer Patients in Rural Western Ethiopia

INTRODUCTION

Endocrine therapy for breast cancer (BC) patients is highly underutilized in rural Ethiopia and other African countries.

OBJECTIVE

This study aims to assess the feasibility of and adherence to tamoxifen therapy in rural Ethiopia.

METHODS

We ascertained the hormone receptor (HR) status in 101 women diagnosed with BC from January 2010 to December 2015 and who had surgery in Aira Hospital, in rural Ethiopia. From 2013, tamoxifen was offered to patients with HR-positive (HR+) tumors. Prescription refill records and a structured questionnaire were used to assess receipt of and adherence to tamoxifen.

RESULTS

Of the 101 BC patients tested for HR status during the study period, 66 (65%) patients were HR+ and were eligible for tamoxifen treatment. However, 15 of the HR+ patients died before tamoxifen became available in 2013. Of the remaining 51 HR+ patients, 26 (51%) initiated tamoxifen but only 9 of them (35%) adhered to therapy (medication possession rate ≥80%, median observation 16.2 months). After 1 year, 52% of the patients were still adherent, and 9 patients had discontinued therapy. The reasons for non-initiation of tamoxifen included patient factors (n = 5), including financial hardship or lack of transportation, and health care provider factors (n = 12).

CONCLUSIONS

Endocrine therapy for BC patients seems feasible in rural Western Ethiopia, although non-adherence due to financial hardship and a less developed health care infrastructure remains a major challenge. We postulate that the implementation of breast nurses could reduce patient and health system barriers and improve initiation of and adherence to endocrine treatment.

Perceived barriers to timely treatment initiation and social support status among women with breast cancer in Ethiopia

Timely care is essential to increase breast cancer survival. However, patients in Ethiopia still face multilevel barriers on their pathway to timely treatment initiation. This cross-sectional study at Tikur Anbessa Specialized Hospital Oncology Unit in Addis Ababa assessed systemic treatment initiation intervals of breast cancer patients and quantified the impact of socio-demographic and clinical factors, perceived barriers, and the patients´ perceived social support status on timely systemic treatment initiation (chemotherapy or hormonal therapy). A structured questionnaire was designed based on Pechansky´s "Concept of Access". Applying simple and multivariate logistic regression we analysed the influence of patients´ characteristics as well as their perceived barriers on timely treatment initiation. We measured social support with the Multidimensional Score of Perceived Social Support (MSPSS) and used the Wilcoxon Rank-Sum Test to assess its relationship with timely treatment initiation. Of 196 patients included into the study, 53% received systemic treatment within 90 days of their pathological diagnosis-the median treatment initiation interval was 85 days (IQR 123.5). Older women and patients diagnosed at late stages had higher odds of timely treatment initiation. Not being able to pay for services and lack of transport were most often perceived as barriers towards timely care. However, none of the perceived barriers showed a substantial influence on timely treatment initiation in the multivariate regression model. The patients´ perceived social support was found to be high, with an average MSPSS score of 73 out of 84 (SD 13,63). No impact of the perceived social support status on timely treatment initiation was found. The percentage of breast cancer patients waiting longer than 90 days from pathological diagnosis to systemic treatment initiation in Ethiopia remains unacceptably high. While women generally feel well supported by their social environment, costs and accessibility of treatment are perceived to be major barriers towards timely treatment initiation.

Provider Barriers and Facilitators of Breast Cancer Guideline-Concordant Therapy Delivery in Botswana: A Consolidated Framework for Implementation Research Analysis

Introduction

Systemic treatment for breast cancer in sub‐Saharan Africa (SSA) is cost effective. However, there are limited real‐world data on the translation of breast cancer treatment guidelines into clinical practice in SSA. The study aimed to identify provider factors associated with adherence to breast cancer guideline‐concordant care at Princess Marina Hospital (PMH) in Botswana.

Materials and Methods

The Consolidated Framework for Implementation Research was used to conduct one‐on‐one semistructured interviews with breast cancer providers at PMH. Purposive sampling was used, and sample size was determined by thematic saturation. Transcribed interviews were double‐coded and analyzed in NVivo using an integrated analysis approach.

Results

Forty‐one providers across eight departments were interviewed. There were variations in breast cancer guidelines used. Facilitators included a strong tension for change and a government‐funded comprehensive cancer care plan. Common provider and health system barriers were lack of available resources, staff shortages and poor skills retention, lack of relative priority compared with HIV/AIDS, suboptimal interdepartmental communication, and lack of a clearly defined national cancer control policy. Community‐level barriers included accessibility and associated transportation costs. Participants recommended the formal implementation of future guidelines that involved key stakeholders in all phases of planning and implementation, strategic government buy‐in, expansion of multidisciplinary tumor boards, leveraging nongovernmental and academic partnerships, and setting up monitoring, evaluation, and feedback processes.

Discussion

The study identified complex, multilevel factors affecting breast cancer treatment delivery in Botswana. These results and recommendations will inform strategies to overcome specific barriers in order to promote standardized breast cancer care delivery and improve survival outcomes.

Implications for Practice

To address the increasing cancer burden in low‐ and middle‐income countries, resource‐stratified guidelines have been developed by multiple international organizations to promote high‐quality guideline‐concordant care. However, these guidelines still require adaptation in order to be successfully translated into clinical practice in the countries where they are intended to be used. This study highlights a systematic approach of evaluating important contextual factors associated with the successful adaptation and implementation of resource‐stratified guidelines in sub‐Saharan Africa. In Botswana, there is a critical need for local stakeholder input to inform country‐level and facility‐level resources, cancer care accessibility, and community‐level barriers and facilitators.

To address an increasing mortality burden, resource‐stratified guidelines have been developed to ensure that breast cancer care is matched to specific resources in low‐ and middle‐income countries. This article identifies facilitators and barriers to the use of breast cancer guidelines by oncology providers at Princess Marina Hospital in Botswana using the Consolidated Framework for Implementation Research (CFIR).

Utilization and predictors of postmastectomy radiation receipt in an Oncology Center in Zimbabwe

PURPOSE

Few sub-Saharan African studies have ascertained utilization for postmastectomy radiation (PMRT) for breast cancer, the second most common cancer among African women. We estimated PMRT utilization and identified predictors of PMRT receipt in Zimbabwe.

METHODS

Retrospective patient cohort included non-metastatic breast cancer patients treated from 2014 to 2019. PMRT eligibility was assigned per NCCN guidelines. Patients receiving chemotherapy for non-metastatic disease were also included. The primary endpoint was receipt of PMRT, defined as chest wall with/without regional nodal radiation. Predictors of receiving PMRT were identified using logistic regression. Model performance was evaluated using the c statistic and Hosmer-Lemeshow test for goodness-of-fit.

RESULTS

201 women with localized disease and median follow-up of 11.4 months (IQR 3.3-17.9) were analyzed. PMRT was indicated in 177 women and utilized in 59(33.3%). Insurance coverage, clinical nodal involvement, higher grade, positive margins, and hormone therapy receipt were associated with higher odds of PMRT receipt. In adjusted models, no hormone therapy (aOR 0.12, 95% CI 0.043, 0.35) and missing grade (aOR 0.07, 95% CI 0.01, 0.38) were associated with lower odds of PMRT receipt. The resulting c statistic was 0.84, with Hosmer-Lemeshow p-value of 0.93 indicating good model fit.

CONCLUSION

PMRT was utilized in 33% of those meeting NCCN criteria. Missing grade and no endocrine therapy receipt were associated with reduced likelihood of PMRT utilization. In addition to practice adjustments such as increasing hypofractionation and increasing patient access to standard oncologic testing at diagnosis could increase postmastectomy utilization.

Breast Self-Examination Practice and Associated Factors Among Women Attending Family Planning Service in Modjo Public Health Facilities Southwest Ethiopia

Purpose

Breast cancer is the leading cause of cancer death worldwide and the second common cancer overall. Breast self-examination is one of the cheapest methods used for the early detection of breast cancer in asymptomatic women. However, the practice of breast self-examination remains low in Ethiopia. Therefore, this study aimed to assess breast self-examination practice and associated factors among women attending family planning services in Modjo public health facilities in southwest Ethiopia.

Patient and Methods

Facility-based cross-sectional study was conducted in Modjo public health facilities from October 01, 2020, to October 30, 2020. Data were collected from 420 women by using an interviewer-administered structured questionnaire. Variables with a P-value ≤0.2 in the bivariate analysis were included in the multivariable logistic regression model. Results of regression analysis were shown as odds ratio (OR) and confidence intervals (95% CI).

Results

Overall 86 (20.5%) of the participants had ever performed breast self-examination. The odds of breast self-examination practice among women with tertiary level of education were 2.14 [AOR: 2.14; 95% CI: (1.45, 6.74)] times higher compared to those with secondary education. Women who knew breast self-examination were 4.32 [AOR: 4.32; 95% CI: (1.81, 10.81)] times higher odds of breast self-examination practice compared to their counterparts. The odds of breast self-examination practice among women who had a positive attitude were 2.7 [AOR: 2.7; 95% CI: (1.03, 6.91)] times higher compared to women with a negative attitude towards breast self-examination.

Conclusion

Breast self-examination practice was low within the study area. Tertiary level of education, having Knowledge on breast self-examination and a positive attitude towards breast self-examination were found to have a significant association with breast self-examination practice. Breast self-examination should be promoted by improving awareness and providing special health education for women that had low educational level.

Genetic Mutations Associated with Hormone-Positive Breast Cancer in a Small Cohort of Ethiopian Women

In Ethiopia, a breast cancer diagnosis is associated with a prognosis significantly worse than that of Europe and the US. Further, patients presenting with breast cancer in Ethiopia are far younger, on average, and patients are typically diagnosed at very late stages, relative to breast cancer patients of European descent. Emerging data suggest that a large proportion of Ethiopian patients have hormone-positive (ER⁺) breast cancer. This is surprising given (1) that patients have late-stage breast cancer at the time of diagnosis, (2) that African Americans with breast cancer frequently have triple negative breast cancer (TNBC), and (3) these patients typically receive chemotherapy, not hormone-targeting drugs. To further examine the similarity of Ethiopian breast tumors to those of African Americans or of those of European descent, we sequenced matched tumor and normal adjacent tissue from Ethiopian patients from a small pilot collection. We identified mutations in 615 genes across all three patients, unique to the tumor tissue. Across this analysis, we found far more mutations shared between Ethiopian patient tissue and that from white patients (103) than we did comparing to African Americans (3). Several mutations were found in extracellular matrix encoding genes with known roles in tumor cell growth and metastasis. We suggest future mechanistic studies on this disease focus on these genes first, toward finding new treatment strategies for breast cancer patients in Ethiopia.

Breast cancer in Zimbabwe: patterns of care and correlates of adherence in a national referral hospital radiotherapy center cohort from 2014 to 2018

Background

Breast cancer is the second most common cancer among women in Zimbabwe. Patients face socioeconomic barriers to accessing oncology care, including radiotherapy. We sought to understand patterns of care and adherence for women with breast cancer in sub‐Saharan Africa (SSA) with radiotherapy access.

Methods

A retrospective cohort was created for women with breast cancer evaluated at the Parirenyatwa Hospital Radiotherapy and Oncology Center (RTC) from 2014 to 2018. Clinical data were collected to define patterns of care. Non‐adherence was modeled as a binary outcome with different criteria for patients with localized versus metastatic disease.

Results

In total, 351 women presented with breast cancer with median age 51 at diagnosis (IQR: 43–61). Receptor status was missing for 71% (248). 199 (57%) had non‐metastatic disease, and 152 (43%) had metastases. Of women with localized disease, 34% received post‐mastectomy radiation. Of women with metastatic disease, 9.7% received radiotherapy. Metastatic disease and missing HIV status were associated with increased odds of study‐defined non‐adherence (aOR: 1.85, 95% CI: 1.05, 3.28; aOR: 2.13, 95% CI: 1.11, 4.05), while availability of ER/PR status was associated with lower odds of non‐adherence (aOR: 0.18, 95% CI: 0.09, 0.36).

Conclusions

Radiotherapy is likely underutilized for women with breast cancer, even in a setting with public sector availability. Exploring patient‐level factors that influence adherence to care may provide clinicians with better tools to support adherence and improve survival. Greater investment is needed in multidisciplinary, multimodality care for breast cancer in SSA.

Factors associated with advanced-stage diagnosis of breast cancer in north-west Ethiopia: a cross-sectional study

Background

Breast cancer tumours are the most common malignant tumours among women in Ethiopia. Although advanced-stage diagnosis of breast cancer is a common problem, evidence-based information is lacking about the magnitude and determinants of advanced-stage presentation in north-west Ethiopia.

Methods

An institution-based, cross-sectional study was conducted at the oncology units of the University of Gondar and Felege Hiwot specialised hospitals. Stages III and IV were considered advanced stage, whereas stages I and II were considered early stages. Data were collected prospectively on newly diagnosed breast cancer patients and entered using the EPI Info version 7.2 and analysed using Statistical Package for the Social Sciences version 23. Multivariable logistic regression was used to identify the determinants of advanced-stage diagnosis of breast cancer. A p-value < 0.05 was used as the cut-off point to select the determinants of the advanced stage.

Result

About 71.2% of breast cancer patients presented with advanced-stage disease. The median age of patients was 40 years. Rural residence (adjusted odds ratio (AOR) = 1.7; 95% confidence interval (CI): 1.02, 2.96), painless breast lump/wound (AOR = 2.5; 95% CI: 1.45, 4.13), travel distance ≥5 km (AOR = 3.2; 95% CI: 1.72, 5.29), not practising breast self-examination (BSE) (AOR = 2.9; 95% CI: 1.30, 6.52), time to presentation ≥3 months (AOR = 1.4; 95% CI: 1.02, 2.37) and misdiagnosed at first visit (AOR = 1.9; 95% CI: 1.09, 3.59) were determinants of advanced-stage breast cancer.

Conclusion

Nearly three-quarters of the patients were diagnosed with advanced-stage breast cancer. Not practising BSE, travel distance ≥5 km, rural residence, painless breast wound/lump and being misdiagnosed at first visit were important determinants of advanced-stage diagnosis of breast cancer. Focused awareness creation programmes for the public and increasing cancer diagnostic centres in the country are crucial to downstage breast cancer at presentation.

Breast Awareness, Self-Reported Abnormalities, and Breast Cancer in Rural Ethiopia: A Survey of 7,573 Women and Predictions of the National Burden

Background

Breast cancer (BC) is the most frequently diagnosed cancer and leading cause of cancer deaths among women in low‐income countries. Ethiopia does not have a national BC screening program, and over 80% of patients are diagnosed with advanced stage disease. The aim of this study was to assess how many women self‐report a breast abnormality and to determine their diagnoses in rural Ethiopia.

Methods

A community‐based cross‐sectional study was conducted among 7,573 adult women. Women were interviewed and educated about breast awareness, and those who reported breast abnormalities underwent clinical examination by experienced surgeons. Ultrasound‐guided fine needle aspiration cytology (FNAC) was obtained, and cytological analysis was performed. The findings were projected to the female population of Ethiopia to estimate current and future burden of diseases.

Findings

Of the 7,573 women surveyed, 258 (3.4%) reported a breast abnormality, 246 (3.2%) received a physical examination, and 49 (0.6%) were found to be eligible for ultrasound‐guided FNAC or nipple discharge evaluation. Of all the cases, five (10.2%) breast malignancies were diagnosed. We projected for Ethiopia that, approximately, 1 million women could self‐report a breast abnormality, 200,000 women could have a palpable breast mass, and 28,000 women could have BC in the country.

Conclusion

The health care system needs to build capacity to assess and diagnose breast diseases in rural areas of Ethiopia. These data can be used for resource allocation to meet immediate health care needs and to promote detecting and treating BC at earlier stages of disease.

Implications for Practice

Routine mammography screening in a resource‐limited country with a young population is neither sensitive nor affordable. Clinical breast examination with consecutive ultrasound‐guided fine needle aspiration cytology may ensure early diagnosis, downstage disease, and reduce breast cancer mortality. This study had the unique opportunity to educate over 7,573 rural women about breast abnormalities and offer clinical and cytological diagnosis for reported breast abnormalities. The findings were extrapolated to show the nationwide burden of breast abnormalities and unmet diagnostic needs. These data will serve as policy guide to improve adequate referral mechanisms and breast diagnostic and treatment facilities.

Developing tailored interventions for the prevention of breast cancer in Ethiopia is a major challenge in this resource‐limited country. This article reports on the proportion of adult women with self‐reported breast abnormalities in a rural region of Ethiopia, assessing the diagnosis of these abnormalities and extrapolating the disease burden for the entire Ethiopian female population.

Factors Associated with Delay in Breast Cancer Presentation at the Only Oncology Center in North East Ethiopia: A Cross-Sectional Study

BACKGROUND

Female breast cancer is becoming an emerging public health problem which accounts for 33% of all cancers in women and 23% of all cancer cases in Ethiopia. The majority of women with breast cancer are diagnosed at later stages due to delayed presentation to seek treatment.

OBJECTIVE

To determine the prevalence and factors associated with patient delay at presentation among breast cancer patients at Dessie Referral Hospital, the only oncology center in North East Ethiopia.

METHODS

We conducted an institution-based cross-sectional study among 204 female patients with pathology-confirmed breast cancer at the only oncology center of North East Ethiopia from January to June 2020. An interviewer administered questionnaire and a medical record data extraction tool were used to address the objective of the study. Patients were said to be delayed for diagnosis if the time duration between first clinical presentations to first clinical consultation was more than 3 months. Then, bivariable and multivariable logistic regression was employed to analyze the association between dependent and independent variables.

RESULTS

Among a total of 209 eligible participants, 5 refused to participate with a response rate of 97.6%. The proportion of patients with delayed presentation was 103 (50.5%), with the median time taken to visit a healthcare provider after recognition of the first symptom was 4 months. Age above 40 years (AOR=4.81; 95% CI=1.26-18.65) P<0.024, college and above educational status (AOR=0.05; 95% CI=0.01-0.77) p<0.036, government employee (AOR=0.19, 95% CI=0.03-0.91) P<0.002, urban residence (AOR= 0.21; 95% CI=0.01-0.82) p<0.001, visit traditional healer (AOR=0.38; 95% CI=0.2-0.69) P<0.0037, and no lump in under armpit (AOR= 9.05; 95% CI=1.14-22.69) P<0.002 were associated with delayed presentation.

CONCLUSION

Delays to seek treatment is generally high in our study. Age, educational status, occupation, residence, visiting traditional healer, and absence of lump in under armpit were significant factors for delayed presentation. Intervention programs focusing on reducing delayed presentation should be employed.

Biomimetic "Nanoplatelets" as a Targeted Drug Delivery Platform for Breast Cancer Theranostics

Breast cancer is a major threat to health and lives of females. Biomimetic nanotechnology brought brighter hope for early diagnosis and treatment of breast cancer. Here, we proposed a platelet (PLT) membrane-derived strategy for enhanced photoacoustic (PA)/ultrasonic (US)/fluorescence (FL) multimodal imaging and augmented synergistic photothermal/chemotherapeutic efficacy in tumor cells. A PA imaging contrast and photothermal agent, nanocarbons (CNs), a chemotherapeutic and FL material, doxorubicin (DOX), and perfluoropentane (PFP) were coencapsulated into the poly(lactic-co-glycolic) acid (PLGA) skeletons. Then, the PLT membranes were coated onto the PLGA NPs, which were named as "nanoplatelets" (DOX-PFP-CNs@PLGA/PM NPs). The "nanoplatelets", which conserved the structural advantages and inherent properties of PLTs, could not only escape from phagocytosis of macrophages but also actively targeted tumor cells by the way of antigen-antibody interactions between P-selectin on the PM and CD44 receptors of the tumor cells. With CNs and DOX loaded in, these "nanoplatelets" could serve as an excellent contrast agent for PA/FL imaging. Under laser irradiation, the "nanoplatelets" could turn light energy into heat energy. The laser-triggered photothermal effect, on the one hand, could ablate the tumor cells immediately, and on the other hand, could initiate the optical droplet vaporization of PFP, which subsequently enhanced US imaging and promoted the discharge of encapsulated DOX from the "nanoplatelets" for remarkably strengthening photothermal therapeutic power in turn. In this work, as compared with the bare drug-loaded nanoparticles, the "nanoplatelets" exhibited much more accumulation in the tumor cells, demonstrating superior multimodal imaging capability and preferable synergistic therapeutic performance. In conclusion, the "nanoplatelets" could serve as contrast agents for US imaging and PA imaging to guide the therapy. What is more, the bioinspired PLT-derived, targeted, and nontoxic "nanoplatelets", which were exploited for multimodal PA/US/FL imaging-guided synergistic photothermal/chemo therapy, will be of great value to breast cancer theranostics in the days to come.

Breast self-examination practice and its determinants among women in Ethiopia: A systematic review and meta-analysis

BACKGROUND

The survival rate from breast cancer is lowest in African countries and the distribution of breast self-examination practice of and its determinants are not well investigated in Ethiopia. Therefore, this systematic review and meta-analysis was designed to determine the pooled prevalence of breast self-examination and its associated factors among women in Ethiopia.

METHODS

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed for this systematic review and meta-analysis. The databases used were; PUBMED, Cochrane Library, Google Scholar, CINAHL, African Journals Online, Dimensions and Summon per country online databases. Search terms used were; breast self-examination, breast cancer screening, early detection of breast cancer and Ethiopia. Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) was used for critical appraisal of studies. The meta-analysis was conducted using STATA 15 software. The pooled meta-analysis was computed to present the pooled prevalence and relative risks (RRs) of the determinate factors with 95% confidence intervals (CIs).

RESULTS

We identified 2,637 studies, of which, 40 articles (with 17,820 participants) were eligible for inclusion in the final meta-analysis. The pooled estimate of breast self-examination in Ethiopia was 36.72% (95% CI: 29.90, 43.53). The regional distribution breast self-examination ranged from 21.2% (95% CI: 4.49, 37.91) in Tigray to 61.5% (95% CI: 53.98, 69.02) in Gambela region. The lowest prevalence of breast self-examination was observed among the general population (20.43% (95% CI: 14.13, 26.72)). Women who had non-formal educational status (OR = 0.4 (95% CI: 0.21, 0.77)), family history of breast cancer (OR = 2.04 (95% CI: 1.23, 3.39)), good knowledge of breast self-examination (OR = 4.8 (95% CI: 3.03, 7.6)) and favorable attitude toward breast self-examination (OR = 2.75, (95% CI: 1.66, 4.55)) were significantly associated with practice of breast self-examination.

CONCLUSIONS

Only a third of women in Ethiopia practiced breast examination despite WHO guidelines advocating for this practice among all women of reproductive age. Intervention programs should address the factors that are associated with breast self-examination. Population specific programs are needed to promote breast self-examination.

Survival Impact and Cost-Effectiveness of a Multidisciplinary Tumor Board for Breast Cancer in Mozambique, Sub-Saharan Africa

BACKGROUND

Despite the international endorsement of multidisciplinary tumor boards (MTBs) for breast cancer care, implementation is suboptimal worldwide, and evidence regarding their effectiveness in developing countries is lacking. We assessed the impact on survival and the cost-effectiveness of implementing an MTB in Mozambique, sub-Saharan Africa.

MATERIALS AND METHODS

This prospective cohort study included 205 patients with breast cancer diagnosed between January 2015 and August 2017 (98 before and 107 after MTB implementation), followed to November 2019. Pre- and post-MTB implementation subcohorts were compared for clinical characteristics, treatments, and overall survival. We used hazard ratios and 95% confidence intervals (CI), computed by Cox proportional hazards regression. The impact of MTB implementation on the cost per quality-adjusted life year (QALY) was estimated from the provider perspective.

RESULTS

We found no significant differences between pre- and post-MTB subcohorts regarding clinical characteristics or treatments received. Among patients with early breast cancer (stage 0-III; n = 163), the 3-year overall survival was 48.0% (95% CI, 35.9-59.1) in the pre-MTB and 73.0% (95% CI, 61.3-81.6) in the post-MTB subcohort; adjusted hazard ratio, 0.47 (95% CI, 0.27-0.81). The absolute 3-year mean cost increase was $119.83 per patient, and the incremental cost-effectiveness ratio was $802.96 per QALY, corresponding to 1.6 times the gross domestic product of Mozambique.

CONCLUSION

The implementation of a MTB in Mozambique led to a 53% mortality decrease among patients with early breast cancer, and it was cost-effective. These findings highlight the feasibility of implementing this strategy and the need for scaling-up MTBs in developing countries, as a way to improve patient outcomes.

IMPLICATIONS FOR PRACTICE

Currently, more than half of the deaths from breast cancer in the world occur in developing countries. Strategies that optimize care and that are adjusted for available resources are needed to improve the outcomes of patients with breast cancer in these regions. The discussion of cases at multidisciplinary tumor boards (MTBs) may improve survival outcomes, but implementation is suboptimal worldwide, and evidence regarding their effectiveness in developing countries is lacking. This study evaluated the impact of implementing an MTB on the care and survival of patients with breast cancer in Mozambique, sub-Saharan Africa and its cost-effectiveness in this low-income setting.

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.

Breast cancer pathology services in sub-Saharan Africa: a survey within population-based cancer registries

BACKGROUND

Pathologists face major challenges in breast cancer diagnostics in sub-Saharan Africa (SSA). The major problems identified as impairing the quality of pathology reports are shortcomings of equipment, organization and insufficiently qualified personnel. In addition, in the context of breast cancer, immunohistochemistry (IHC) needs to be available for the evaluation of biomarkers. In the study presented, we aim to describe the current state of breast cancer pathology in order to highlight the unmet needs.

METHODS

We obtained information on breast cancer pathology services within population-based cancer registries in SSA. A survey of 20 participating pathology centres was carried out. These centres represent large, rather well-equipped pathologies. The data obtained were related to the known population and breast cancer incidence of the registry areas.

RESULTS

The responding pathologists served populations of between 30,000 and 1.8 million and the centres surveyed dealt with 10-386 breast cancer cases per year. Time to fixation and formalin fixation time varied from overnight to more than 72 h. Only five centres processed core needle biopsies as a daily routine. Technical problems were common, with 14 centres reporting temporary power outages and 18 centres claiming to own faulty equipment with no access to technical support. Only half of the centres carried out IHC in their own laboratory. For three centres, IHC was only accessible outside of the country and one centre could not obtain any IHC results. A tumour board was established in 13 centres.

CONCLUSIONS

We conclude that breast cancer pathology services ensuring state-of-the-art therapy are only available in a small fraction of centres in SSA. To overcome these limitations, many of the centres require larger numbers of experienced pathologists and technical staff. Furthermore, equipment maintenance, standardization of processing guidelines and establishment of an IHC service are needed to comply with international standards of breast cancer pathology.

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.

Few Losses to Follow-up in a Sub-Saharan African Cancer Cohort via Active Mobile Health Follow-up

Accurate survival estimates are needed for guiding cancer control efforts in sub-Saharan Africa, but previous studies have been hampered by unknown biases due to excessive loss to follow-up (LTFU). In the African Breast Cancer-Disparities in Outcomes Study, a prospective breast cancer cohort study, we implemented active mobile health follow-up, telephoning each woman or her next-of-kin (NOK) trimonthly on her mobile phone to update information on her vital status. Dates of every contact with women/NOK were analyzed from diagnosis in 2014-2017 to the earliest of September 1, 2018, death, or 3 years postdiagnosis. The cumulative incidence of being LTFU was calculated considering deaths as competing events. In all, 1,490 women were followed for a median of 24.2 (interquartile range (IQR), 14.2-34.5) months, corresponding to 8,529 successful contacts (77% of total contacts) with the women/NOK. Median time between successful contacts was 3.0 (IQR, 3.0-3.7) months. In all, 71 women (5.3%) were LTFU at 3 years: 0.8% in Nigeria, 2.2% in Namibia, and 5.6% in Uganda. Because of temporary discontinuity of active follow-up, 20.3% of women were LTFU after 2 years in Zambia. The median time to study notification of a death was 9.1 (IQR, 3.9-14.0) weeks. Although the present study was not a randomized controlled trial, in this cancer cohort with active mobile health follow-up, LTFU was much lower than in previous studies and enabled estimation of up-to-date and reliable cancer survival.

Factors associated with late-stage diagnosis of breast cancer among women in Addis Ababa, Ethiopia

PURPOSE

Stage at diagnosis is a key determinant of breast cancer prognosis. In this study, we characterize stage at diagnosis and determine factors associated with advanced stage at diagnosis among women diagnosed with invasive breast cancer in Addis Ababa, capital city of Ethiopia.

METHODS

Stage information was collected from medical records of 441 women with invasive breast cancer seen in seven major health facilities in Addis Ababa, from January 2017 to June 2018; these seven facilities capture 90% of all incident breast cancer cases in the city. We used multivariable Poisson regression model with robust variance to determine factors associated with advanced stage at diagnosis.

RESULTS

The predominant tumor histology was ductal carcinoma (83.7%). More than half of the tumors' grade was moderately or poorly differentiated. The median tumor size at presentation was 4 cm. Sixty-four percent of the patients were diagnosed at advanced stage of the disease (44% stage III and 20% stage IV), with 36% of the patients diagnosed at early-stage (5% stage I and 31% stage II). The prevalence of advanced stage disease was significantly higher among women who used traditional medicine before diagnostic confirmation (adjusted prevalence ratio [aPR] = 1.31; p = 0.001), had patient delay of >  3 months (aPR = 1.16; p = 0.042) and diagnosis delay of > 2 months (aPR = 1.24; p = 0.004). But it was lower among women who had history of breast self-examination (aPR = 0.77; p = 0.021).

CONCLUSIONS

Advanced stage at diagnosis of breast cancer among women in Addis Ababa is strongly associated with use of traditional medicine and with prolonged time interval between symptom recognition and disease confirmation. Community- and health systems-level interventions are needed to enhance knowledge about breast cancer and facilitate timely diagnoses.

Establishing Cohorts to Generate the Evidence Base to Reduce the Burden of Breast Cancer in Sub-Saharan Africa: Results From a Feasibility Study in Kenya

PURPOSE

By 2025, Kenya is estimated to experience a two-thirds increase in the incidence of breast cancer. Local research is necessary to generate evidence to inform policy, public health, and medical practice. There have been no longitudinal cohort studies in sub-Saharan Africa of women with and without breast cancer. Our aim is to assess the feasibility of conducting cohort studies in Kenya that consider clinical characteristics, socioeconomic factors, and self-care behaviors.

METHODS

We initiated a short-term follow-up cohort study of women with and without a diagnosis of breast cancer with baseline face-to-face data collection and one follow-up interview (at approximately 3 months by telephone). We developed tailored instruments to capture demographics, socioeconomic factors, breast cancer risk, ability to identify breast cancer symptoms, treatments received for breast cancer, and quality of life of survivors.

RESULTS

We recruited 800 women between the ages of 20 and 60 years and successfully collected baseline data. Completeness of the data was high for demographic variables, but there was a larger proportion of missing information for specific variables required for assessing breast cancer risk. Respondents were able to complete standardized instruments to assess breast cancer knowledge among those without breast cancer and identification of symptoms among survivors. We were able to successfully contact approximately 80% of the participants for follow-up.

CONCLUSION

This short-term follow-up study provides evidence that women can be successfully tracked and contacted for follow-up in the Kenyan setting and offers lessons to establish future longitudinal cohorts to identify approaches to improve breast cancer outcomes.

Breast Cancer Survival and Incidence: 10 Years Cancer Registry Data in the Northwest, Iran

Methods

Data were obtained from East Azerbaijan cancer registry database for the 10-year period between 2007 and 2016. Survival analysis was performed to calculate the breast cancer-specific survival proportions and mortality rates. Joinpoint trend analysis was performed to estimate the incidence trend of the cancer.

Results

A total number of 4989 patients were recorded with primary diagnosis of breast cancer. Of them, we collected follow-up data for 1335 (1309 female and 26 male). The 10-year crude mortality rate was 3.34 (per 100,000). The one-, two-, three-, five-, and ten-year breast cancer-specific survival proportions were 0.92 (95% CI 0.91-0.93), 0.88 (95% CI 0.86-0.90), 0.84 (95% CI 0.83-0.86), 0.77 (95% CI 0.74-0.80), and 0.65 (95% CI 0.60-0.70), respectively. Over the study period, the age-standardized incidence rates increased from 21.68 to 36.99 (per 100,000) with an annual percentage change of 5.5 percent. Older individuals and males patients had significantly worse survival, and patients with high-grade tumors had significantly higher risk of mortality.

Conclusion

A relatively better survival for breast cancer in East Azerbaijan, Iran, was observed compared to the overall breast cancer-specific survival proportions and mortality rates in the country. However, it is still poor compared to the developed countries indicating that inappropriate treatment modalities might have played a role on this.

Social networks and quality of life among female breast cancer patients at Tikur Anbessa specialized hospital, Addis Ababa, Ethiopia 2019

Background

Breast cancer is a major life-threatening global public health problem. It is the most common form of cancer in females in many developing countries including Ethiopia. Social networks could change the course of cancer and can influence the quality of life among breast cancer patients. Therefore, the purpose of this study was to assess social networks and quality of life among female breast cancer patients attending in Tikur Anbassa Specialized Hospital, Addis Ababa, Ethiopia 2019.

Methods

An institutional-based cross-sectional study was conducted in Tikur Anbessa Specialized Hospital Addis Ababa, Ethiopia from March 1 to April 30/2019. A total of 214 female breast cancer patients were included Binary and multiple logistic regression was used to show the association of social networks and quality of life.

Result

A total of 214 females with breast cancer were recruited with a mean age of 41.85. Participants who had children (AOR = 5, 95%CL: 1.3,21 COR = 6), and other relatives (AOR = 6, 95%CI: 1.2,30, COR = 7), were more likely to have good social networks. Participants who were not married (AOR = 0.02, 95%CI: 0.03, 0.28), had no parents living (AOR = 0.1, 95%CI: 0.02, 0.4), no close friends (AOR = 0.06, 95%CI: 0.01, 0.4), and no neighbors (AOR = 0.09, 95%CI: 0.03, 0.5) had poor social networks.

Conclusion

The quality of life was relatively low and social support were found to be poor in women with breast cancer. Health-care providers in oncology departments need to focus on addressing the side effects of therapy and social networks which may help to improve the quality of life of females with breast cancer.

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.

Regional, racial, gender, and tumor biology disparities in breast cancer survival rates in Africa: A systematic review and meta-analysis

BACKGROUND

The survival rates from breast cancer in Africa are poor and yet the incidence rates are on the rise. In this study, we hypothesized that, in Africa, a continent with great disparities in socio-economic status, race, tumor biology, and cultural characteristics, the survival rates from breast cancer vary greatly based on region, tumor biology (hormone receptor), gender, and race. We aimed to conduct the first comprehensive systematic review and meta-analysis on region, gender, tumor-biology and race-specific 5-year breast cancer survival rates in Africa and compared them to 20-year survival trends in the United States.

METHODS

We searched MEDLINE, EMBASE, and Cochrane Library to identify studies on breast cancer survival in African published before October 17, 2018. Pooled 5-year survival rates of breast cancer were estimated by random-effects models. We explored sources of heterogeneity through subgroup meta-analyses and meta-regression. Results were reported as absolute difference (AD) in percentages. We compared the survival rates of breast cancer in Africa and the United States.

FINDINGS

There were 54 studies included, consisting of 18,970 breast cancer cases. There was substantial heterogeneity in the survival rates (mean 52.9%, range 7-91%, I2 = 99.1%; p for heterogeneity <0.0001). Meta-regression analyses suggested that age and gender-adjusted 5-year survival rates were lower in sub-Saharan Africa compared to north Africa (AD: -25.4%; 95% CI: -34.9 - -15.82%), and in predominantly black populations compared to predominantly non-black populations (AD: -25.9%; 95% CI: 35.40 - -16.43%). Survival rates were 10 percentage points higher in the female population compared to male, but the difference was not significant. Progesterone and estrogen receptor-positive breast cancer subtypes were positively associated with survival (r = 0.39, p = 0.08 and r = 0.24, p = 0.29 respectively), but triple-negative breast cancer was negatively associated with survival. Survival rates are increasing over time more in non-black Africans (55% in 2000 versus 65% in 2018) compared to black Africans (33% in 2000 versus 40% in 2018); but, the survival rates for Africans are still significantly lower when compared to black (76% in 2015) and white (90% in 2015) populations in the United States.

CONCLUSION

Regional, sub-regional, gender, and racial disparities exist, influencing the survival rates of breast cancer in Africa. Therefore, region and race-specific public health interventions coupled with prospective genetic studies are urgently needed to improve breast cancer survival in this region.

Time intervals experienced between first symptom recognition and pathologic diagnosis of breast cancer in Addis Ababa, Ethiopia: a cross-sectional study

OBJECTIVES

This study aimed to estimate the magnitude of patient and diagnostic delays and associated factors among women with breast cancer in Addis Ababa.

DESIGN

This is a cross-sectional study.

SETTINGS AND PARTICIPANTS

All women newly diagnosed with breast cancer in seven major healthcare facilities in Addis Ababa (n=441) were included in the study.

MAIN OUTCOMES AND MEASURES

Patient interval (time from recognition of first symptom to medical consultation) and diagnostic interval (time from first consultation to diagnosis). Patient intervals >90 days and diagnostic intervals >30 days were considered delays, and associated factors were determined using multivariable Poisson regressions with robust variance.

RESULTS

Thirty-six percent (95% CI [31.1%, 40.3%]) of the patients had patient intervals of >90 days, and 69% (95% CI [64.6%, 73.3%]) of the patients had diagnostic intervals of >30 days. Diagnostic interval exceeded 1 year for 18% of patients. Ninety-five percent of the patients detected the first symptoms of breast cancer by themselves, with breast lump (78.0%) as the most common first symptom. Only 8.0% were concerned about cancer initially, with most attributing their symptoms to other factors. In the multivariable analysis, using traditional medicine before consultation was significantly associated with increased prevalence of patient delay (adjusted prevalence ratio (PR) = 2.13, 95% CI [1.68, 2.71]). First consultation at health centres (adjusted PR = 1.19, 95% CI [1.02, 1.39]) and visiting ≥4 facilities (adjusted PR = 1.24, 95% CI [1.10, 1.40]) were associated with higher prevalence of diagnostic delay. However, progression of symptoms before consultation (adjusted PR = 0.73, 95% CI [0.60, 0.90]) was associated with decreased prevalence of diagnostic delay.

CONCLUSIONS

Patients with breast cancer in Addis Ababa have prolonged patient and diagnostic intervals. These underscore the need for public health programme to increase knowledge about breast cancer symptoms and the importance of early presentation and early diagnosis among the general public and healthcare providers.

Quality of life and associated factors among patients with breast cancer under chemotherapy at Tikur Anbessa specialized hospital, Addis Ababa, Ethiopia

Background

Breast cancer is the most common cancer affecting women in Ethiopia with increasing burden, and chemotherapy treatment produces a detrimental effect on individual wellbeing. Since last few years quality of life has been the primary goal of cancer treatment, yet little research has been conducted on quality of life of breast cancer patients under chemotherapy.

Objective

To determine the quality of life and associated factors among patients with breast cancer under chemotherapy at Tikur Anbessa specialized hospital, Addis Ababa, Ethiopia.

Methods

Institution based cross-sectional study was conducted on 404 patients with breast cancer, who took at least one cycle of chemotherapy treatment using face to face interview at oncology unit of Tikur Anbessa specialized hospital day care center from February to April 2018. The validated Amharic version of European organization for research and treatment of cancer core 30 (EORTC QLQ-C30) and quality of life questionnaire specific to breast (QLQ-BR23) was used to measure health related quality of life. Both descriptive and inferential statistics were used. For the purpose of interpretation quality of life score was dichotomized in to two using the calculated mean score, which is 53 as a cutoff point, then, bi-variable and multivariable logistic regression was used to describe association between dependent and independent variables. Hence, patients who score above 53 for quality of life were considered to have good quality of life.

Result

Of the total sample, overall response rate was 99.77%. The average quality of life score of patients with breast cancer under chemotherapy treatment was 52.98 (SD = 25.61). Majority of patients had scored poor in emotional functioning, sexual functioning, and financial difficulties. Educational status of college and above, being divorced, higher household income, higher scores of physical and social functioning were associated with significantly improved (better) quality of life. Lower scores of fatigue, insomnia, financial difficulties and systemic therapy side effects all were associated with better scores of quality of life of breast cancer patients. Whereas, patients receiving < = 2 cycles of chemotherapy had significantly lower scores of quality of life.

Conclusion and recommendation

Quality of life of breast cancer patients under chemotherapy treatment is poor in comparison with the reference data and international findings. Therefore, quality of life assessment should be incorporated in patient’s treatment protocol. And financial aids may significantly improve the quality of life of breast cancer patients under chemotherapy treatment.

Addis Ababa population-based pattern of cancer therapy, Ethiopia

Cancer in Sub-Saharan Africa is becoming an important challenge for health services due to rising numbers of patients. In Addis Ababa with around 3.5 million inhabitants, more than 2000 cases are diagnosed annually. In this retrospective population-based cohort study we assessed completeness of and waiting time for cancer-therapy among patients registered in the Addis Ababa City Cancer Registry (AACCR), Ethiopia. Patient hospital files were retrieved to complete the data from AACCR. A total of 588 files were found (51% of those diagnosed from January to March 2012 and 2014). We analyzed completeness and waiting time of chemotherapy and radiotherapy; with completeness defined as ≥85% therapy received according to local guidelines. Analysis was done for the five most common cancer-types commonly treated with chemotherapy (breast, colorectal, non-Hodgkin`s lymphoma, lung and ovarian) and the four most common cancer-types commonly treated with radiotherapy (breast, cervical, head and neck and rectal). In our study, half of the patients (54.1%) received adequately dosed chemotherapy and 24.5% of patients received adequately dosed radiotherapy. The median waiting time was 2.1 months (Range: 0 to 20.72) for chemotherapy and 7 months (Range: 0.17 to 21.8) for radiotherapy. This study underscores the need for health system measures to improve cancer-directed therapy in Ethiopia, especially concerning radiotherapy.

Perspectives of patients, family members, and health care providers on late diagnosis of breast cancer in Ethiopia: A qualitative study

Background

Most women with breast cancer in Ethiopia are diagnosed at an advanced stage of the disease, but the reasons for this have not been systematically investigated. This study, therefore, aimed to explore the main reasons for diagnosis of advanced stage breast cancer from the perspective of patients, family members, and health care providers.

Methods

A qualitative study with in-depth interviews was conducted with 23 selected participants at Tikur Anbessa Specialized Hospital, Oncology Clinic using a semi-structured interview guide. These participants were 13 breast cancer patients, 5 family members, and 5 health care providers. Data were transcribed into English, coded and analyzed using thematic analysis.

Results

Awareness about the causes, risk, initial symptoms, early detection methods, and treatment of breast cancer were uncommon, and misconceptions about the disease prevailed among breast cancer patients and family members. There was a sense of hopelessness and uncertainty about the effectiveness of conventional medicine amongst patients and family members. Consequently, performing spiritual acts (using holy water) or seeking care from traditional healers recurred amongst the interviewees. Not taking initial symptoms of breast cancer seriously by the patients, reliance on traditional medicines, competing priorities, financial hardship, older age, fear of diagnosis of cancer, and weak health systems (e.g., delay in referral and long waiting period for consultation) were noted as the main contributors to late diagnosis. In contrast, persuasion by family members and friends, higher educational attainment, and prior experience of neighboring women with breast cancer were mentioned to be facilitators of early diagnosis of breast cancer.

Conclusions

The causes of late diagnosis of breast cancer in Ethiopia are multi-factorial and include individual, cultural, and health system factors. Interventions targeting these factors could alleviate the misconceptions and knowledge gap about breast cancer in the community, and shorten waiting time between symptom recognition and diagnosis of breast cancer.

CYP2J2∗7 Genotype Predicts Risk of Chemotherapy-Induced Hematologic Toxicity and Reduced Relative Dose Intensity in Ethiopian Breast Cancer Patients

Chemotherapy-induced hematologic toxicity is the primary reasons of dose reductions and/or delays, low relative dose intensity (RDI), and predicts anticancer response. We investigated the incidence and predictors of chemotherapy-induced hematologic toxicities and reduced RDI in Ethiopian breast cancer patients, and implication of pharmacogenetics variations. Breast cancer patients (n = 249) were enrolled prospectively to receive cyclophosphamide based chemotherapy. Hematological toxicity (neutropenia, anemia, and thrombocytopenia) were monitored throughout chemotherapy cycle. The primary and secondary outcomes were incidence of grade 3 or 4 toxicity and reduced RDI, respectively. CYP2B6^∗6, CYP3A5^∗3, CYP2C9 (^∗2,^∗3), CYP2C19 (^∗2,^∗3), CYP2J2^∗7, POR^∗28, and ABCB1 (rs3842) genotyping were done. Cox proportional hazard and logistic regression were used to estimate risk predictors of toxicity and reduced RDI, respectively. Majority (73.5%) of the patients were < 45 years of age. The incidence of grade 3 or 4 hematological toxicity was 51.0% (95% CI = 44.54–57.46%). Multivariate Cox proportional hazard regression indicated CYP2J2^∗7 genotype [Hazard ratio (HR) = 1.82; 95% CI = 1.14–2.90], pretreatment grade 1 leukopenia (HR = 2.75; 95% CI = 1.47–5.15) or grade 1 or 2 neutropenia (HR = 2.75; 95% CI = 1.73–4.35) as significant predictors of hematologic toxicities. The odds of having hematologic toxicities was lower in CYP2C9^∗2 or ^∗3 carriers (p = 0.024). The prevalence of reduced RDI was 56.6% (95% CI = 50.3–62.9%). Higher risk of reduced RDI was associated with CYP2J2^∗7 allele [Adjusted odds ratio (AOR) = 2.79; 95% CI = 1.21–6.46], BMI ≤ 18.4 kg/m² (AOR = 5.98; 95% CI = 1.36–26.23), baseline grade 1 leukopenia (AOR = 6.09; 95% CI = 1.24–29.98), and baseline neutropenia (AOR = 3.37; 95% CI = 1.41–8.05). The odds of receiving reduced RDI was lower in patients with CYP2B6 ^∗6/^∗6 genotype (AOR = 0.19; 95% CI = 0.06–0.77). We report high incidence of chemotherapy-induced hematological toxicities causing larger proportion of patients to receive reduced RDI in Ethiopian breast cancer patients. Patients carrying CYP2J2^∗7 allele and low baseline blood counts are at a higher risk for chemotherapy-induced hematologic toxicities and receiving reduced RDI, and may require prior support and close follow up during chemotherapy.

Breast and cervical cancer patients' experience in Addis Ababa city, Ethiopia: a follow-up study protocol

INTRODUCTION

Cancer is an emerging public health problem in Ethiopia, with breast and cervical cancers accounting for over half of all newly diagnosed cancers in women. The majority of women with breast and cervical cancer are diagnosed at late stage of the disease and most patients do not receive care consistent with global standards. However, little is known about the health-seeking behaviours, barriers to early detection and treatment, patient-reported outcomes, financial burden and survival of women with breast and cervical cancer in the country. Therefore, this study aims to document the experience of women with breast and cervical cancer from recognition of symptoms to diagnosis, treatment and survivorship/mortality in Addis Ababa city, Ethiopia.

METHODS AND ANALYSIS

A prospective follow-up study using mixed methods (both quantitative and qualitative) will be employed. All women newly diagnosed with breast and cervical cancer from 1 January, 2017 to 30 June 2018 in Addis Ababa will be included in the study. Interviewer-administered questionnaires will be used to collect information about medical consultations after recognition of symptoms, health-seeking behaviours, treatment received, barriers to early detection and treatment, and survivorship care. In-depth interview will be conducted on purposefully selected women with breast and cervical cancer. The primary outcomes of the study are time intervals (patient and diagnostic waiting times), stage at diagnosis and survival. Multivariable analysis will be employed to determine the contributions of independent variables on the outcomes of interest. HRs with 95% CIs will be calculated for time-to-event outcomes. Qualitative data will be analysed using thematic analysis.

ETHICS AND DISSEMINATION

This protocol is ethically approved by Institutional Review Board of Addis Ababa University. Verbal informed consent will be obtained from study participants. Results will be disseminated in international peer-reviewed journals and presented in relevant conferences.
