RESUMO

BACKGROUND: Although mastectomy is the standard treatment modality for breast cancer patients in Ethiopia, our previous study revealed that one in five patients do not receive the recommended procedure, half due to patient refusal or lack of returning to the hospital. Therefore, this study aimed to explore reasons for refusing mastectomy and identify challenges among breast cancer patients in Ethiopia. METHODS: An explorative qualitative study was conducted in four hospitals located in the towns of Woliso, Butajira, Hossana, and Assela. A total of 14 in-depth interviews (IDIs) and eight focus group discussions (FGDs) were held with breast cancer patients, patient relatives, and health professionals. Four semi-structured interview guides were used to facilitate the IDIs and FDGs. All recorded IDIs and FGDs were transcribed and translated verbatim and entered in NVivo 12 software. Emerging ideas were categorised and explained using an inductive content analysis approach. RESULTS: Our participants reported that particularly elderly and very young women refuse to have mastectomy. The main reasons identified in this study were summarised into six themes: (i) fear of the surgical procedure, (ii) religious beliefs and practice, (iii) utilisation of traditional treatments, (iv) in relation to having a baby and breastfeeding their children (young patients often request to remove only the lump, leaving their breast tissue intact), (v) lack of awareness about the disease, and (vi) sociocultural factors and advice from the community that influence women, since breasts are considered an attribute of femininity, beauty, and motherhood. In addition, knowing someone who died after mastectomy emerged as a main reason for not having breast cancer surgery. CONCLUSIONS: High refusal rate for mastectomy has direct implication on increased breast cancer mortality. Hence, expansion of radiotherapy service is instrumental to initiate breast-conserving surgery as an alternative surgical procedure, especially for young women with early-stage breast cancer. Involving religious leaders, traditional healers, and breast cancer survivors could be an effective strategy to persuade newly diagnosed breast cancer patients. Addressing individual patient psychosocial needs and preferences may substantially improve retention of breast cancer patients in the health system.

RESUMO

Cancer diagnosis and treatment can be physically arduous, disrupting patients' social and work lives. Understanding the extent of these problems is key to addressing patients' needs, but specific psychosocial challenges have not yet been well studied in resource-limited settings. A qualitative study was conducted in the capital and two regions of Ethiopia with the aim of exploring psychosocial challenges among cancer patients. A total of 14 in-depth interviews (IDIs) and 16 focus group discussions (FGDs) were done with cancer patients, health professionals, community representatives, and religious leaders. Four separate interview guides were used to facilitate the interviews and discussions. All transcribed documents, field notes, and reflexive memos were entered into NVivo 12 software, and deductive thematic analysis using the social-ecological model was applied to summarize the main findings. At an individual level, emotional distress, suicidal risk, denial, and refusal of treatment were identified immediately after diagnosis while hopelessness, feeling depressed, and fear of death were commonly reported psychosocial challenges during the course of treatment. Involvement of family members in major treatment decisions was recognized at an interpersonal level. Our result also revealed that cancer patients had strong social support from family members and close friends. In the community, traditional medicine and religious rituals were considered an alternative treatment for cancer. The findings indicate that counselling and psychoeducation are crucial for cancer patients, family members, and close friends. Awareness creation programmes should be delivered through collaboration with religious leaders and traditional healers.

RESUMO

BACKGROUND: Cancer is becoming a major public health problem globally and a leading cause of death in children in developed countries. However, little is known about the epidemiology of childhood cancer in Ethiopia. This study, therefore, assessed childhood cancer incidence patterns in Addis Ababa using the Addis Ababa city population-based cancer registry data from 2012 to 2017. METHODS: Invasive cancer cases diagnosed in ages 0-14 years from 2012 to 2017 were obtained from the Addis Ababa City population-based Cancer Registry. Cases were grouped according to the International Classification of Childhood Cancer, 3rd edition (ICCC-3) based on morphology and primary anatomic site. Age-standardized incidence rates (ASR) were calculated by the direct method using the world standard population. RESULTS: The overall average annual incidence rate during 2012-2017 in children was 84.6 cases per million, with rates higher in boys (98.97 per million) than in girls (69.7 per million). By age, incidence rates per million increased from 70.8 cases in ages 0-4 years to 88.4 cases in ages 5-9 years to 110.0 cases 10-14 years. Leukaemia was the most common childhood cancer in both boys (29.1%) and girls (26.8%), followed by lymphoma in boys (24.7%) and renal tumours (13.1%) in girls. The overall cancer incidence rate decreased from 87.02 per million in 2012 to 51.07 per million in 2017. CONCLUSION: The burden of childhood cancer is considerably high in Addis Ababa. The observed distribution of childhood cancer in Addis Ababa differs from other African countries. This study highlights the need for further research and understanding of the variations in cancer patterns and risk factors across the region.

RESUMO

BACKGROUND: Global cancer estimations for Ethiopia announced 77 352 new cases in 2020 based on the only population-based registry in Addis Ababa. This study characterizes cancer patients in rural Ethiopia at 8 primary and secondary hospitals between 2014 and 2019. PATIENTS AND METHODS: All clinically or pathologically confirmed cancer cases that were diagnosed between 1 May 2014 and 29 April 2019 were included. A structured data extraction tool was used to retrospectively review patients' charts and descriptive analysis was done. RESULTS: A total of 1298 cancer cases were identified, of which three-fourths were females with a median age of 42 years. Breast (38%) and cervical (29%) cancers were the most common among females, while prostate (19%) and oesophageal cancers (16%) were the most common among males. Only 39% of tumors were pathologically confirmed. Nearly two-thirds of the cases were diagnosed at an advanced stage. Surgery was the only accessible treatment option for more than half of the cancer patients, and systemic treatment (except endocrine) was rarely available. One in 5 patients did not receive the recommended surgical procedure, half due to patient refusal or lack of the patient returning to the hospital. CONCLUSION: The pattern of cancer diagnoses in rural hospitals shows an exceptionally high burden in women in their middle-ages due to breast and cervical cancers. Advanced stage presentation, lack of pathology services, and unavailability of most systemic treatment options were common. The surgery was offered to nearly 60% of the patients, showing the significant efforts of health workers to reduce sufferings.

RESUMO

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.

RESUMO

There is shortage of radiotherapy machines in low-income countries, including Ethiopia. Data on adverse effects of this on cancer outcomes are limited, however. Herein, we examined the extent of waiting time for radiotherapy and its association with disease progression based on a prospective cohort study of women diagnosed with stage IA-IVA cervical cancer in Addis Ababa and who were scheduled to receive radiotherapy at Tikur Anbessa Specialized Hospital, the only hospital that provides radiotherapy services in the country. Association was examined using Multivariable mixed effects logistic regression model. Among the 178 women with cervical cancer scheduled for receipt of radiotherapy and with vital status information, 16 deceased (9.0%) while waiting for radiotherapy. For the remaining 162 women who initiated radiotherapy, the median treatment waiting period was 137 days (IQR = 60-234 days), with 74.1% of women waiting for >60 days. Tumor progressed to higher stage for 44.4% of these women. Compared to those women who initiated radiotherapy ≤60 days after diagnostic confirmation, the odds of tumor progression to higher stage was three times higher in those women who initiated radiotherapy between 120-179 days (aOR =3.30, 95%CI: 1.18-9.27) and ≥180 days (aOR =3.06, 95%CI: 1.24-7.52). Waiting period for receipt of radiotherapy among women with cervical cancer is exceedingly long in Addis Ababa, and it is associated with disease progression to higher stages. These findings reinforce the need to expand radiotherapy infrastructure in order to mitigate the undue high burden of the disease in Ethiopia and other parts of Africa.

RESUMO

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.

RESUMO

PURPOSE: Chemotherapy within 90 days following surgery for non-metastatic breast cancer is the standard of care. There are no data, however, on the extent of time to initiation of chemotherapy (TTC) in Africa settings, including Ethiopia. METHODS: A total of 223 women with stage I-III breast cancer treated with surgery and adjuvant chemotherapy during 2017-2019 in Addis Ababa, Ethiopia, were included in the analysis. Based on information from medical records, we calculated TTC from date of surgery and completion of planned chemotherapy, with TTC > 90 days considered delayed and receipt of 85% of planned therapy as complete. Multivariable Poisson regression with robust variance was used to assess whether TTC > 90 days was associated with sociodemographic or clinical factors. RESULTS: The median TTC was 63 days. Chemotherapy initiation was delayed in 30% (95% CI 24.4-36.6%) of patients, with the risk significantly higher in low-income women. For example, the risk of delay in women with lowest quartile family monthly income group (US$ < 61) was 3.98 (95% CI 1.67-9.46) higher than in those women with highest quartile family income group (US$ > 194). Remarkably, adjuvant chemotherapy was completed in 95% of patients. CONCLUSIONS: A staggering one-in-three women with breast cancer in Addis Ababa, Ethiopia, delay to initiation of adjuvant chemotherapy, with the delay more common in low-income women and yet with remarkably high degree of treatment adherence. These findings underscore the need for public policy to expand health care to low-income population to improve breast cancer care and other health outcomes in the country.

RESUMO

OBJECTIVES: To estimate observed and relative survival of prostate cancer patients in sub-Saharan Africa (SSA) and to examine the influence of age, stage at diagnosis and the Human Development Index (HDI). PATIENTS AND METHODS: In this comparative registry study, we selected a random sample of 1752 incident cases of malign prostatic neoplasm from 12 population-based cancer registries from 10 SSA countries, registered between 2005 and 2015. We analyzed the data using Kaplan-Meier and Ederer II methods to obtain outcome estimates and flexible Poisson regression modeling to calculate the excess hazards of death RESULTS: For the 1406 patients included in the survival analyses, 763 deaths occurred during 3614 person-years of observation. Of patients with known stage, 45.2% had stage IV disease, 31.2% stage III and only 23.6% stage I and II. The 1 and 5-year relative survival for the entire cohort was 78.0% (75.4-80.7) and 60.0% (55.7-64.6), while varying between the registries. Late presentation was associated with increased excess hazards and a 0.1 increase in the HDI was associated with a 20% lower excess hazard of death, while for age at diagnosis no association was found. CONCLUSIONS: We found poor survival of SSA prostatic tumor patients, as well as high proportions of late stage presentation, which are associated with inferior outcome. This calls for investment in health-care systems and action regarding projects to raise awareness among the population to achieve earlier diagnosis and improve survival.

RESUMO

BACKGROUND: Breast cancer is the second leading cause of cancer in the world. It is the commonest type of cancer in Ethiopia. Cognitive problems are common among breast cancer patients. The study aimed to assess cognitive functioning and its associated factors among breast cancer patients at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia 2020. METHODS: Institution-based comparative cross-sectional study was conducted. Study subjects were 117 breast cancer patients on chemotherapy and 117 women without breast cancer who volunteered for the study. Data was collected from May-June 2020. The Mini-mental status exam (MMSE) was used to assess cognitive functioning. Data were entered into Epi Data version 4.6.0.2 and analyzed using STATA version 14 software. Univariable and multivariable linear regression model was fitted to identify factors associated with cognitive functioning. A two-tailed p-value less than 0.05 was used to declare statistical significance. RESULTS: Among the total breast cancer patients 41.9% were diagnosed with earlier sage of the diseases (stage I and II), while the rest 58.1% were diagnosed with stage III and stage IV breast cancer. A significant difference in the MMSE score was observed among breast cancer patients and controls (19.76 ± 5.29, 25.18 ± 4.68 p <  0.0001) respectively. In multivariable linear regression analysis being non-breast cancer (Adjusted beta coefficient (Adj.ß.coff). = 3.34, 95% CI (1.92-4.76) p <  0.001), hemoglobin gm/dl (Adj.ß.coff =0.34, 95% CI (0.04-0.63) p = 0.02), and primary education (Adj.ß.coff =2.98 95%CI (1.16-4.96) p = 0.001) secondary level and more education (Adj.ß.coff = 5.47, 95%CI (3.51-7.28) p < 0.001) were significantly associated with MMSE cognitive score. CONCLUSION: Breast cancer patients had lower mean MMSE scores when compared to non-breast cancer women. Higher hemoglobin level and higher level of education increase the MMSE cognitive score. Clinicians should incorporate routine screening of cognitive functioning for breast cancer patients and further study is required to evaluate cognitive impairment among breast cancer patients in Ethiopia.

RESUMO

BACKGROUND: Cervical cancer is the second commonly diagnosed cancer and the second leading cause of cancer death in women in Ethiopia, with rates among the highest worldwide. However, there are limited data on cervical cancer treatment patterns and survival in the country. Herein, we examine treatment patterns and survival of cervical cancer patients treated in Tikur Anbessa Hospital Radiotherapy Center (TAHRC), the only hospital with radiotherapy facility in the country. METHODS: Women with histologically verified cervical cancer who were seen in 2014 (January 1, 2014 to December 31, 2014) at TAHRC were included. Information about clinical characteristics and treatments were extracted from the patients' medical record files. The information on vital status was obtained from medical chart and through telephone calls. RESULT: Among 242 patients included in the study, the median age at diagnosis was 48 years. The median waiting time for radiotherapy was 5.6 months (range 2 to 9 months). Stage migration occurred in 13% of patients while waiting for radiotherapy. Consequently, the proportion of patients with stage III or IV disease increased from 66% at first consultation to 74% at the initiation of radiotherapy. Among 151 patients treated with curative intent, only 34 (22.5%) of the patients received concurrent chemotherapy while the reaming patients received radiotherapy alone. The 5-year overall survival rate was 28.4% (20.5% in the worst-case scenario). As expected, survival was lower in patients with advanced stage at initiation of radiotherapy and in those treated as palliative care. CONCLUSION: The survival of cervical cancer patients remains low in Ethiopia because of late presentation and delay in receipt of radiotherapy, leading to stage migration in substantial proportion of the cases. Concerted and coordinated multisectoral efforts are needed to promote early presentation of cervical cancer and to shorten the unacceptable, long waiting time for radiotherapy.

RESUMO

Breast cancer is the leading cancer diagnosis and second most common cause of cancer deaths in sub-Saharan Africa (SSA). Yet, there are few population-level survival data from Africa and none on the survival differences by stage at diagnosis. Here, we estimate breast cancer survival within SSA by area, stage and country-level human development index (HDI). We obtained data on a random sample of 2,588 breast cancer incident cases, diagnosed in 2008-2015 from 14 population-based cancer registries in 12 countries (Benin, Cote d'Ivoire, Ethiopia, Kenya, Mali, Mauritius, Mozambique, Namibia, Seychelles, South Africa, Uganda and Zimbabwe) through the African Cancer Registry Network. Of these, 2,311 were included for survival analyses. The 1-, 3- and 5-year observed and relative survival (RS) were estimated by registry, stage and country-level HDI. We equally estimated the excess hazards adjusting for potential confounders. Among patients with known stage, 64.9% were diagnosed in late stages, with 18.4% being metastatic at diagnosis. The RS varied by registry, ranging from 21.6%(8.2-39.8) at Year 3 in Bulawayo to 84.5% (70.6-93.5) in Namibia. Patients diagnosed at early stages had a 3-year RS of 78% (71.6-83.3) in contrast to 40.3% (34.9-45.7) at advanced stages (III and IV). The overall RS at Year 1 was 86.1% (84.4-87.6), 65.8% (63.5-68.1) at Year 3 and 59.0% (56.3-61.6) at Year 5. Age at diagnosis was not independently associated with increased mortality risk after adjusting for the effect of stage and country-level HDI. In conclusion, downstaging breast cancer at diagnosis and improving access to quality care could be pivotal in improving breast cancer survival outcomes in Africa.

RESUMO

BACKGROUND: Management of patients with breast cancer undergoing chemotherapy is complicated by a very high rate of adverse drug reactions which is even more challenging in developing countries like Ethiopia where the toxicity profile of chemotherapy is lacking. The present study aimed at evaluating the toxicity profile of Doxorubicin-Cyclophosphamide (AC) and Doxorubicin-Cyclophosphamide→Paclitaxel (AC→T) regimens among 146 patients with breast cancer in Ethiopia. METHODS: This prospective cohort study, with the median of six months' follow-up, was conducted from January 1 to September 30, 2017 GC at the only nationwide oncology center, Tikur Anbessa Specialized Hospital (TASH), Addis Ababa, Ethiopia. Seventy-one patients received AC, while 75 received AC-T regimen. The toxicity with the highest grade during any cycle was considered as the toxicity grade for that patient. SPSS version 22 was used for analysis. RESULTS: The overall frequent non-hematological adverse drug reactions reported for both regimens were fatigue 144 (98.7%), dysgeusia 142 (97.3%), skin hyperpigmentation 141 (96.6%), nausea 136 (93.2%), vomiting 129 (88.4%), gastritis 122 (83.6%), peripheral neuropathy 108 (74%), and myalgia/arthralgia 110 (75.3%). Neutropenia 107 (73.3%), leukopenia 102 (69.9%), and anemia 51 (34.9%) were the most frequent overall grade hematological toxicities reported. However, those received AC regimen suffered more from grade 2 and above leukopenia (35.2% vs. 17.3%, P = 0.014), anemia (16.9% vs. 2.7%, P = 0.004), and alkaline phosphatase increment (11.3% vs. 2.7%, P = 0.039) than AC-T regimen. On the contrary, those received AC-T regimen suffered more from severe arthralgia/myalgia (2.8% vs. 2%, P = 0.001), peripheral neuropathy (1.4% vs. 36%, P = 0.000), and gastritis (14.1% vs. 29.3%, P = 0.026) than AC regimen. Pretreatment blood cell counts, having stage IV breast tumor, older age, and lower body surface area were significant predictors of grade 2 to above hematological toxicities. Older age, arthralgia/myalgia, and skin hyperpigmentation occurred during the cohort were significant predictors of grade 2 to above oral mucositis, peripheral neuropathy, and fatigue, respectively. CONCLUSION: Patients who received the AC regimen suffered more from hematological abnormalities, while those on the AC-T regimen experienced more of non-hematological toxicities. Overall, we report high incidences of AC and AC-T regimens-induced toxicities in Ethiopian women with breast cancer, and they may require prior support based on pretreatment blood counts, age and body surface area, and close follow-up during chemotherapy.

RESUMO

BACKGROUND: Rapid Ethical Assessment (REA) is an approach used to design context tailored consent process for voluntary participation of participants in research including human subjects. There is, however, limited evidence on the design of ethical assessment in studies targeting cancer patients in Ethiopia. REA was conducted to explore factors that influence the informed consent process among female cancer patients recruited for longitudinal research from Addis Ababa Population-based Cancer Registry. METHODS: Qualitative study employing rapid ethnographic approach was conducted from May-July, 2017, at the Tikur Anbessa Specialized Referral Hospital. In-depth and key informants' interviews were conducted among purposively selected 16 participants. Regular de-briefings among the study team helped to identify emerging themes and ensure saturation. Interviews and debriefings were tape recorded in Amharic, and transcribed and translated to English. Coding of the transcripts was facilitated by use of NVivo software. Thematic analysis was employed to respond to the initial questions and interpret findings. RESULTS: Perceived barriers to voluntary study participation included lack of reporting back study results of previous studies, the decision making status of women, hopelessness or fatigue in the patients, shyness of the women, data collectors approach to the patient, and patient's time constraints. Most of the patients preferred oral over written consent and face-to-face interview over telephone interview. Provision of detail information about the study, using short and understandable tool, competent, compassionate and respectful enumerators of the same gender were suggested to assure participation. Due to the perceived severity, the use of the term "cancer" was associated with fear and anxiety. Alternatively, uses of phrases like "breast or cervical illness/disease" were suggested during patient interviews. CONCLUSIONS: Voluntary participation is not straight forward but affected by different factors. Using competent, compassionate and respectful enumerators, short and precise questioning tools to limit the time of the interview could improve voluntary participation. Moreover, careful consideration of the patients and families concept of the disease such as wording and information has to be taken into account. This assessment helped in improving the consent process of the ongoing project on breast and cervical cancer patients.

RESUMO

Background: In low-income countries, oesophageal cancer often presents at an advanced stage, leaving patients with limited curative treatment options. Furthermore, palliative treatments such as oesophageal stents or brachytherapy are lacking. This has a detrimental effect on their quality of life. In this study, we investigated the health-related quality of life of patients with oesophageal cancer at a tertiary hospital in Ethiopia. Methods: This cross-sectional study was conducted at Tikur Anbessa Specialised Tertiary Hospital in Ethiopia. The validated Amharic version of the questionnaire of the European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire Cancer 30 (EORTC QLQ C-30) and the oesophageal cancer disease-specific questionnaire QLQ-OES18 were used to assess the quality of life of each patient. Results: The overall mean score for the EORTC QLQ C-30 was 35.43 (SD 18.04). The mean scores for the functional scales revealed that cognitive function was the highest, whereas role function was the lowest. The symptom scale results showed the highest score for pain and the lowest for diarrhoea. Dysphagia, choking, role functioning and financial difficulty correlated with the quality of life of patients with oesophageal cancer. Conclusion: Dysphagia, choking, role functioning and financial difficulty are important factors that affect the quality of life of patients with oesophageal cancer patients. Increasing the availability of palliative treatments for dysphagia to improve the quality of life in patients with oesophageal cancer is recommended.

RESUMO

PURPOSE: Head and neck cancers (HNCs) are the third most commonly treated cancer with radiation in Ethiopia. Most patients present with advanced stage and are not candidates for curative treatment. The objective of our study is to assess the outcome of hypofractionated palliative radiotherapy (RT) for advanced HNCs in a resource-limited setting. MATERIALS AND METHODS: Patients with histology-proven advanced HNC candidates for hypofractionated palliative RT were enrolled. Three regimens were allowed: 44.4 Gy in 12 fractions, 30 Gy in 10 fractions, and 20 Gy in five fractions. Response to treatment was assessed at baseline and at 4 weeks after treatment completion. The Kaplan-Meier curve was used to measure the survival. RESULTS: Between January 2022 and January 2023, 52 patients were enrolled and 25 patients were eligible for outcome assessment. Index symptoms include pain, bleeding, dysphagia, respiratory distress, and others in 25, 13, 10, 6, and 17 patients, respectively. Complete relief of the top three symptoms include pain in 52% of patients, hemostasis in 84% of patients, and dysphagia in 30% of patients. Objectively, 64% of patients attained partial response. For 48% of patients, their quality of life (QoL) improved in one parameter of the physical scores. Moreover, 64% of patients showed improvement in three parameters. The global functional score improved in 80% of patients. One patient had grade 3 xerostomia. At the end of the study period, 44% of patients died. The median survival after radiation was 9 months (95% CI, 7.2 to 10.8). CONCLUSION: All palliative hypofractionated regimens used were effective in terms of symptom control, tumor response rate, and QoL, and were well tolerated. This makes it appropriate for our setup because the majority of patients require palliation.

RESUMO

BACKGROUND: To assess population-based quality of cancer care in Sub-Saharan Africa and to identify specific gaps and joint opportunities, we assessed concordance of diagnostic and treatment with NCCN harmonized guidelines for leading cancer types in 10 countries. METHODS: Adult patients with female breast cancer (BC), cervical cancer (CC), colorectal cancer (CRC), Non-Hodgkin lymphoma (NHL) and prostate cancer (PC) were randomly drawn from 11 population-based cancer registries. Guideline concordance of diagnostics and treatment was assessed using clinical records. In a sub-cohort of 906 patients with potentially curable cancer (stage I-III BC, CC, CRC, PC, aggressive NHL (any stage)) and documentation for >1 month after diagnosis, we estimated factors associated with guideline-concordant treatment or minor deviations (GCT). FINDINGS: Diagnostic information as per guidelines was complete for 1030 (31.7%)of 3246 patients included. In the sub-cohort with curable cancer, GCT was documented in 374 (41.3%, corresponding to 11.7% of 3246 included in the population-based cohort): aggressive NHL (59.8%/9.1% population-based), BC (54.5%/19.0%), PC (39.0%/6.1%), CRC (33.9%/9.5%), and CC (27.8%/11.6%). GCT was most frequent in Namibia (73.1% of curable cancer subset/32.8% population-based) and lowest in Kampala, Uganda (13.5%/3.1%). GCT was negatively associated with poor ECOG status, locally advanced stage, origin from low HDI countries, and a diagnosis of CRC or CC. INTERPRETATION: Quality of diagnostic workup and treatment showed major deficits, with considerable disparities among countries and cancer types. Improved diagnostic services are necessary to increase the share of curable cancer in SSA. Treatment components within NCCN guidelines synergetic for several cancers should be prioritized.

RESUMO

PURPOSE: There are limited data on the association between delay in breast cancer diagnosis after breast symptom recognition and survival, particularly in sub-Saharan Africa. The recently launched Global Breast Cancer Initiative by WHO includes measuring delay as the core indicator for quality of breast cancer care. Herein, we examined the association between delay in breast cancer diagnosis with overall survival among women in Addis Ababa, Ethiopia. MATERIALS AND METHODS: A total of 439 women diagnosed with breast cancer from January 1, 2017, to June 30, 2018, in Addis Ababa were followed for survival to the end of 2019. Survival rates were estimated using the Kaplan-Meier method. The association between delay in diagnosis (>3 months after symptom recognition) and overall survival was computed using the multivariable Cox regression model after adjusting for demographic and clinical factors. RESULTS: Nearly 70% (303/439) of women with breast cancer were delayed in diagnosis of their cancer. During a median follow-up period of 25.1 months, 2-year overall survival rate was 73.5% (95% CI, 68.0 to 78.2) in women with diagnosis delay compared with 79.1% (95% CI, 71.2 to 85.1) in those women without diagnosis delay. In the multivariable Cox regression model, the risk of death was 73% higher (hazard ratio, 1.73; 95% CI, 1.09 to 2.74) in women with diagnosis delay compared with those without diagnosis delay. CONCLUSION: Delay in diagnostic confirmation of breast cancer after recognition of breast symptoms was negatively associated with overall survival in Addis Ababa, Ethiopia, underscoring the need to increase awareness about the importance of prompt presentation for clinical evaluation and referral for diagnostic confirmation to mitigate the undue high burden of the disease.

RESUMO

BACKGROUND: Colorectal cancer (CRC) is the third most common cause of cancer death in both genders worldwide. AIMS: This study aimed to evaluate the outcomes and prognostic factors of CRC patients at Tikur Anbessa Specialized Hospital in Ethiopia. METHODS AND RESULTS: A prospective cohort study was conducted on 209 patients from January 2020 to September 2022. Kaplan-Meier curves and bivariate and multivariate Cox regression analyses were used to analyze overall and progression-free survival, with a significance value of P < .05. Results showed an overall mortality rate was 67.46% (95% confidence interval [CI]: 61.0-74.0), while the 1-year overall survival (OS) rate was 63.16% (95% CI: 56.23-69.29), with a median follow-up duration of 20 months. The median OS and progression-free survival times were 17 and 11 months, respectively. Age above 40 years (hazard ratio [HR] = 1.53, 1.02-2.29, p < .040), lower educational level (high school and below) (HR = 2.20, 1.24-3.90, p < .007), poor performance status (HR = 1.60, 1.03-2.48, p < .035), Hgb ≤12.5 g/dL (HR = 1.55, 1.03-2.08, p < .035), T-4 disease (HR = 6.05, 2.28-16.02, p < .000), and metastases at diagnosis (HR = 8.53, 3.77-19.25, p < .000) were all associated with poorer survival. CONCLUSION: These findings suggest that poor survival of CRC patients in Ethiopia is largely due to advanced stage of the disease and lack of timely treatment, and highlight the urgent need for improved access to cancer treatment in the region.

RESUMO

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.
