Ovarian cancer survival in sub-Saharan Africa by human development index and histological subtypes: A population-based registry study.

Ovarian cancer (OC) is the fourth most common cancer of women in sub-Saharan Africa (SSA), although few data have been published on population-level survival. We estimate ovarian cancer survival in SSA by human development index and histological subtype, using data from seven population-based cancer registries in six countries: Kenya (Nairobi and Eldoret), Mauritius, Uganda (Kampala), Cote d'Ivoire (Abidjan), Ethiopia (Addis Ababa) and South Africa (Eastern Cape). A total of 644 cases diagnosed during 2008-2014 were included, with 77% being of epithelial subtypes (range 47% [Abidjan]-80% [Mauritius]). The overall observed survival in the study cohort was 73.4% (95% CI: 69.8, 77.0) at 1 year, 54.4% (95% CI: 50.4, 58.7) at 3 years and 45.0% (95% CI: 41.0, 49.4) at 5 years. Relative survival at Year 1 ranged from 44.4% in Kampala to 86.3% in Mauritius, with a mean for the seven series of 67.4%. Relative survival was highest in Mauritius at 72.2% and lowest in Kampala, Uganda at 19.5%, with a mean of 47.8%. There was no difference in survival by age at diagnosis. Patients from high and medium HDI countries had significantly better survival than those from low HDI countries. Women with cancers of epithelial cell origin had much lower survival compared to women with other histological subtypes (p = .02). Adjusted for the young age of the African patients with ovarian cancer (44% aged <50) survival is much lower than in USA or Europe, and underlines the need for improvements in the access to diagnosis and treatment of OC in SSA.

Adherence to Treatment and Follow-Up of Precancerous Cervical Lesions in Ethiopia.

BACKGROUND: In Ethiopia, both incidence and mortality of cervical cancer are relatively high. Screening services, which were implemented during the past few years, are currently being expanded. The World Health Organization recommends patients with a positive VIA (visual inspection with acetic acid) result should immediately receive treatment followed by rescreening after 1 year as precancerous lesions can reoccur or become residential despite treatment. MATERIALS AND METHODS: Screening logbooks dating between 2017 and 2020 were retrospectively reviewed in 14 health facilities of Addis Ababa and Oromia region. Data for 741 women with a VIA-positive result were extracted and those women were asked to participate in a questionnaire-based phone interview to gain insights about adherence to treatment and follow-up. Data were analyzed using descriptive methods and then fitted into 2 generalized linear models to test variables for an influence on adherence to follow up. RESULTS: Around 13 800 women had received a VIA screening, of which approximately 820 (5.9%) were VIA positive. While over 90% of women with a positive screen received treatment, only about half of the treated patients returned for a follow-up examination. After treatment, 31 women had a VIA-positive re-screen. We found that educational status, age over 40, no/incorrect follow-up appointment, health facility-related barriers, and use of reminders are important drivers of adherence to follow up. CONCLUSION: Our results revealed that adherence to treatment after VIA positive screening is relatively high whereas adherence to follow up recommendations still needs improvement. Reminders like appointment cards and phone calls can effectively reduce the loss of follow-up.

Prognostic and predictive impact of NOTCH1 in early breast cancer.

PURPOSE: Systemic therapy plays a major part in the cure of patients with early breast cancer (eBC). However, personalized treatment concepts are required to avoid potentially harmful overtreatment. Biomarkers are pivotal for individualized therapy. The Notch signalling pathway is widely considered as a suitable prognostic or predictive marker in eBC. This study aimed primarily at assessing the relationship between NOTCH1 mRNA expression levels and histopathological features of breast cancer tumors, as well as clinical characteristics of the correspondent eBC patients. As a secondary aim, we investigated the prognostic and predictive value of NOTCH1 by assessing possible associations between NOTCH1 mRNA expression and recurrence-free interval (RFI) and overall survival after five years of observation. PATIENTS AND METHODS: The relative NOTCH1 mRNA expression was determined in 414 tumour samples, using quantitative PCR in a prospective, multicenter cohort (Prognostic Assessment in Routine Application (PiA), 2009-2011, NCT01592825) of 1,270 female eBC patients. RESULTS: High NOTCH1 mRNA expression was detected in one-third of the tumours and was associated with negative hormone receptor status and high uPA/PAI-1 status. In addition, high NOTCH1 mRNA expression was found to be associated with more RFI related events (adjusted hazard ratio 2.1, 95% CI 1.077-4.118). Patients who received adjuvant chemotherapy and had high NOTCH1 mRNA expression in the tumour (n = 86) were three times more likely to have an RFI event (adjusted hazard ratio 3.1, 95% CI 1.321-7.245, p = 0.009). CONCLUSION: In this cohort, NOTCH1 mRNA expression had a prognostic and predictive impact. Tumours with high NOTCH1 mRNA expression may be less sensitive to cytotoxic treatment and downregulation of the Notch signalling pathway (e.g. by γ-secretase inhibitors) may be valuable for eBC therapy as an individualised treatment option.

"How can a woman live without having a breast?": challenges related to mastectomy in Ethiopia.

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.

Understanding referral of patients with cancer in rural Ethiopia: a qualitative study.

BACKGROUND: Cancer incidence is increasing in Ethiopia mainly due to increased life expectancy, while oncological capacities remain limited. Strong referral linkages between different levels of the healthcare system are key to provide timely access to cancer care. In this qualitative study, we assessed limitations and potential of cancer patient referral in the rural Southwest of Ethiopia. METHODS: We held four focus group discussions (FGD) with health professionals at one primary and three secondary hospitals and conducted eight in-depth interviews (IDI) with the hospitals´ medical executives and local health bureau representatives. Data was analysed inductively using thematic analysis and emerging themes were categorized within the revised concept of access by Penchansky and Saurman. RESULTS: The inevitable referral of patients with cancer in the rural Southwest of Ethiopia is characterized by the absence of clear communication protocols and the lack of formal referral linkages. The newly implemented hub-system has improved emergency referrals and could be expanded to non-emergency referrals, sensitive to the needs of advanced oncological care. Liaison officers can pave the way but need to be trained and equipped adequately. Referred patients struggle with inadequate transportation systems, the lack of accommodation close to specialized facilities as well as the inability to navigate at those sites due to language barriers, illiteracy, and stigmatization. Few Non-Governmental Organizations (NGOs) help but cannot compensate the limited governmental support. The shortage of medications at public hospitals leads to patients being directed to costly private pharmacies. In the light of those challenges, cancer remains to be perceived as a "death sentence" within the rural communities. CONCLUSIONS: Standardized referral linkages and a multi-faceted support network throughout the cancer care continuum are necessary to make oncology care accessible to Ethiopia´s large rural population.

PAM50 breast cancer subtypes and survival of patients in rural Ethiopia without adjuvant treatment: a prospective observational study.

PURPOSE: Survival rates of breast cancer (BC) patients are particularly low in rural regions in sub-Saharan Africa (SSA) which is due to limited access to therapy. In recent years, gene expression profiling (GEP) of BC showed a strong prognostic value in patients with local tumour surgery and (neo)adjuvant treatment. The aim of this study was to evaluate the impact of intrinsic subtypes on survival of patients in rural Ethiopia without any (neo)adjuvant therapy. METHODS: In total, 113 female patients from Aira Hospital with histologically proven BC and treated only with surgery were included in this study. All samples were analysed by immunohistochemistry (IHC) for estrogen receptor, progesterone receptor, HER2 and Ki67, as well as RNA-expression analysis for PAM50 subtyping. RESULTS: A positive hormone receptor status was found in 69.0% of the tumours and intrinsic subtyping demonstrated Luminal B to be the most common subtype (34.5%). Follow-up data was available for 79 of 113 patients. Two-year overall survival (OS) was 57.3% and a considerably worse OS was observed in patients with Basal-like BC compared to Luminal A BC. Moreover, advanced tumours showed an increased risk of mortality. CONCLUSION: The OS was very low in the patient cohort that received no (neo)adjuvant treatment. Immunohistochemistry and GEP confirmed endocrine-sensitive tumours in more than half of the patients, with a large proportion of Luminal B, HER2-enriched and Basal-like tumours so that adjuvant chemotherapy should be recommended.

Climate-sensitive health counselling in Germany: a cross-sectional study about previous participation and preferences in the general public.

BACKGROUND: In response to climate change (CC), medicine needs to consider new aspects in health counselling of patients. Such climate-sensitive health counselling (CSHC) may include counselling patients on preventing and coping with climate-sensitive diseases or on leading healthy and climate-friendly lifestyles. This study aimed to identify previous participation in and preferences for CSHC as well as associated sociodemographic and attitudinal factors among the general public in Germany. METHODS: We conducted a cross-sectional study in a population-based online panel in five German federal states (04-06/2022). We performed descriptive statistics and multivariable regression analysis to assess prior participation in CSHC and content preferences regarding CSHC, as well as associations between sociodemographic variables and general preference for CSHC. RESULTS: Among 1491 participants (response rate 47.1%), 8.7% explicitly reported having participated in CSHC, while 39.9% had discussed at least one CSHC-related topic with physicians. In the studied sample, 46.7% of participants would like CSHC to be part of the consultation with their physician, while 33.9% rejected this idea. Participants aged 21 to 40 years (versus 51 to 60), individuals alarmed about CC (versus concerned/cautious/disengaged/doubtful/dismissive), and those politically oriented to the left (vs. centre or right) showed greater preference for CSHC in the multivariable regression model. Most participants wanted to talk about links to their personal health (65.1%) as opposed to links to the health of all people (33.2%). CONCLUSIONS: Almost half of the participants in this sample would like to receive CSHC, especially those who are younger, more alarmed about CC and more politically oriented to the left. More research and training on patient-centred implementation of CSHC is needed.

User profiles in digitalized healthcare: active, potential, and rejecting - a cross-sectional study using latent class analysis.

BACKGROUND: There is evidence of different use by different groups of people for general health-related applications. Yet, these findings are lacking for digitalized healthcare services. It is also unclear whether typical use patterns can be found and how user types can be characterized. METHODS: The analyses are based on data from 1 821 respondents to the Health Related Beliefs and Health Care Experiences in Germany panel (HeReCa). Digitalized healthcare services, that were used to determine the user types, include for example sick notes before/after examination and disease related training. User types were determined by latent class analysis. Individual groups were characterized using multinomial logistic regressions, taking into account socioeconomic and demographic factors as well as individual attitudes towards digitalization in the healthcare system. RESULTS: Three types were identified: rejecting (27.9%), potential (53.8%) and active (18.3%). Active participants were less likely to be employed, less likely to be highly educated and less skeptical of digital technologies. Potential users were the youngest, most highly-educated and most frequently employed group, with less skepticism than those who rejected. Rejecters were the oldest group, more likely to be female and of higher socio-economic status. CONCLUSIONS: Socio-demographic and socio-economic differences were identified among three user types. It can therefore be assumed that not all population groups will benefit from the trend towards digitalization in healthcare. Steps should be taken to enhance access to innovations and ensure that everyone benefits from them.

A Qualitative Study on Psychosocial Challenges of Patients With Cancer in Ethiopia Using the Social-Ecological Model.

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.

[Subjective Health Impairment And Associated Factors In The Heatwave Of Summer 2022: An Online Survey]. / Subjektive gesundheitliche Beeinträchtigung und assoziierende Faktoren in der Hitzeperiode des Sommers 2022 ­ Ein Online-Survey.

BACKGROUND: Heatwaves might diminish the sense of well-being and are associated with increased mortality. Individual measures to protect against heat are often insufficient, with the perception of one's own risk playing a crucial role. Due to varying levels of vulnerability, it is expected that the perception differs among populations. Presumably, symptom awareness is higher when people are concerned with and inform themselves about the topic of heat. Our study examined subjective health impairment during the heatwave in 2022, its association with socio-demographic and economic factors, as well as perceived heat stress and individual engagement with the issue. METHOD: An online survey of a population-based sample from five federal states of Germany was carried out. Multivariable regression analyses were conducted to explore the relationship between subjective health impairment due to heat and potential risk indicators. RESULTS: Out of 3,111 people contacted, 1,522 responded, with 649 (20.9%) included in the analysis as they were affected by heat in their region of residence during the summer of 2022. The average subjective health impairment was 9.29 (SD: 5.25) out of 29 possible points. Higher age was associated with lower impairment; -1.36 points (95%-CI: -4.10; 1.38) in the group of those aged 80 and compared with the reference group of 60 to 69-year-old people. Furthermore, higher impairment was reported more by women and individuals with lower educational levels. Low impairment was associated with a high perceived level of information. CONCLUSION: Interventions aimed at reducing heat-related health problems should target a broader audience, particularly young people, women, individuals with lower education, and working people.

The effect of cognitive behavioural therapy integrated with activity pacing on cancer-related fatigue, depression and quality of life among patients with breast cancer undergoing chemotherapy in Ethiopia: A randomised clinical trial.

Fatigue is a common symptom experienced by 80% of individuals who receive chemotherapy and is one of the major factors that affect quality of life (QoL) of patients with breast cancer. Our study aimed to assess the effect of cognitive behavioural therapy integrated with activity pacing (CBT-AP) on cancer-related fatigue among patients with breast cancer undergoing chemotherapy. A parallel-group, randomised controlled trial was conducted. Severely fatigued patients were randomly assigned to the CBT-AP or usual care (UC) groups using a computer-generated random sequence. The new intervention was designed for seven sessions: three 2-hour face-to-face and four 30-minute telephone sessions. The primary outcome (fatigue severity) and the secondary outcomes (depression and QoL) were assessed at the end of the intervention and after 3 months. The data were analysed by repeated measures analyses of covariance (RM-ANCOVA). CBT-AP had a significant time effect (P < .001, ηp2  = 0.233) in reducing fatigue from baseline (adjusted mean = 7.48) to the end of the intervention (adjusted mean = 6.37) and the 3-month follow-up (adjusted mean = 6.54). Compared to the UC group, the CBT-AP group had lower fatigue and depression scores, and higher global health status scores. The group × time interaction revealed a significant reduction in fatigue and depression in the CBT-AP group compared to the UC group. Therefore, CBT-AP appears to be effective in reducing fatigue and depression and improving QoL in patients with breast cancer undergoing chemotherapy. It is highly recommended to integrate a CBT-AP intervention in routine cancer care.

Trends in the incidence of ovarian cancer in sub-Saharan Africa.

Ovarian cancer (OC) is one of the commonest cancers of women in sub-Saharan Africa (SSA), although to date no data have been available on time trends in incidence to better understand the disease pattern in the region. We estimate time trends by histological subtype from 12 population-based cancer registries in 11 countries: Kenya (Nairobi), Mauritius, Seychelles, Uganda (Kampala), Congo (Brazzaville), Zimbabwe (Bulawayo and Harare), Cote d'Ivoire (Abidjan), The Gambia, Mali (Bamako), Nigeria (Ibadan) and South Africa (Eastern Cape). The selected registries were those that could provide consistent estimates of the incidence of ovarian cancer and with quality assessment for periods of 10 or more years. A total of 5423 cases of OC were included. Incidence rates have been increasing in all registries except Brazzaville, Congo, where a nonsignificant decline of 1% per year was seen. Statistically significant average annual increases were seen in Mauritius (2.5%), Bamako (5.3%), Ibadan (3.9%) and Eastern Cape (8%). Epithelial ovarian cancer was responsible for the increases observed in all registries. Statistically significant average annual percentage changes (AAPC) for epithelial OC were present in Bamako (AAPC = 5.9%), Ibadan (AAPC = 4.7%) and Eastern Cape (AAPC = 11.0%). Creating awareness among professionals of the growing importance of the disease is surely an important step to improving availability of, and access to, diagnosis and treatment of OC in SSA. Support must be given to the cancer registries to improve the availability of good-quality data on this important cancer.

Pathways and Referral of Patients with Cancer in Rural Ethiopia: A Multi-center Retrospective Cohort Study.

INTRODUCTION: Well-organized patient pathways are essential to achieve early diagnosis and timely treatment of patients with cancer in Sub-Saharan Africa. This retrospective cohort study describes pathways and referral patterns of cancer patients in rural Ethiopia. PATIENTS AND METHODS: The retrospective study took place from October to December 2020 at 2 primary- and 6 secondary-level hospitals in southwestern Ethiopia. Of 681 eligible patients diagnosed with cancer between July 2017 and June 2020, 365 patients were included. Structured interviews on the patients' pathways were conducted by telephone. The primary outcome was successful referral, which was defined as occurring when the intended procedure was initiated at the receiving institution. Logistic regression was used to assess factors associated with successful referrals. RESULTS: Patients visited on average 3 health care institutions from their first encounter with a provider until their final treatment initiation. After diagnosis, only 26% (95) of patients were referred for further cancer treatment, of which 73% were successful. Patients referred for diagnostic tests were 10 times more likely to complete referrals successfully than patients referred for treatment. Overall, 21% of all patients remained without any therapy. CONCLUSION: We found that referral pathways of patients with cancer in rural Ethiopia were largely cohesive. The majority of patients referred for diagnostic or treatment services followed the advice. Nevertheless, an unacceptable number of patients remained without any treatment. Capacity for cancer diagnosis and treatment at primary- and secondary-level health facilities in rural Ethiopia must be expanded to enable early detection and timely care.

Guideline Concordance of Treatment and Outcomes Among Adult Non-Hodgkin Lymphoma Patients in Sub-Saharan Africa: A Multinational, Population-Based Cohort.

BACKGROUND: Although non-Hodgkin lymphoma (NHL) is the 6th most common malignancy in Sub-Saharan Africa (SSA), little is known about its management and outcome. Herein, we examined treatment patterns and survival among NHL patients. METHODS: We obtained a random sample of adult patients diagnosed between 2011 and 2015 from 11 population-based cancer registries in 10 SSA countries. Descriptive statistics for lymphoma-directed therapy (LDT) and degree of concordance with National Comprehensive Cancer Network (NCCN) guidelines were calculated, and survival rates were estimated. FINDINGS: Of 516 patients included in the study, sub-classification was available for 42.1% (121 high-grade and 64 low-grade B-cell lymphoma, 15 T-cell lymphoma and 17 otherwise sub-classified NHL), whilst the remaining 57.9% were unclassified. Any LDT was identified for 195 of all patients (37.8%). NCCN guideline-recommended treatment was initiated in 21 patients. This corresponds to 4.1% of all 516 patients, and to 11.7% of 180 patients with sub-classified B-cell lymphoma and NCCN guidelines available. Deviations from guideline-recommended treatment were initiated in another 49 (9.5% of 516, 27.2% of 180). By registry, the proportion of all patients receiving guideline-concordant LDT ranged from 30.8% in Namibia to 0% in Maputo and Bamako. Concordance with treatment recommendations was not assessable in 75.1% of patients (records not traced (43.2%), traced but no sub-classification identified (27.8%), traced but no guidelines available (4.1%)). By registry, diagnostic work-up was in part importantly limited, thus impeding guideline evaluation significantly. Overall 1-year survival was 61.2% (95%CI 55.3%-67.1%). Poor ECOG performance status, advanced stage, less than 5 cycles and absence of chemo (immuno-) therapy were associated with unfavorable survival, while HIV status, age, and gender did not impact survival. In diffuse large B-cell lymphoma, initiation of guideline-concordant treatment was associated with favorable survival. INTERPRETATION: This study shows that a majority of NHL patients in SSA are untreated or undertreated, resulting in unfavorable survival. Investments in enhanced diagnostic services, provision of chemo(immuno-)therapy and supportive care will likely improve outcomes in the region.

Incidence and pattern of childhood cancer in Addis Ababa, Ethiopia (2012-2017).

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.

Treatment and Survival Among Patients With Colorectal Cancer in Sub-Saharan Africa: A Multicentric Population-Based Follow-Up Study.

BACKGROUND: The burden of colorectal cancer (CRC) is increasing in Sub-Saharan Africa (SSA). However, little is known about CRC treatment and survival in the region. METHODS: A random sample of 653 patients with CRC diagnosed from 2011 to 2015 was obtained from 11 population-based cancer registries in SSA. Information on clinical characteristics, treatment, and/or vital status was obtained from medical records in treating hospitals for 356 (54%) of the patients ("traced cohort"). Concordance of CRC treatment with NCCN Harmonized Guidelines for SSA was assessed. A Cox proportional hazards model was used to examine the association between survival and human development index (HDI). RESULTS: Of the 356 traced patients with CRC, 51.7% were male, 52.8% were from countries with a low HDI, 55.1% had colon cancer, and 73.6% were diagnosed with nonmetastatic (M0) disease. Among the patients with M0 disease, however, only 3.1% received guideline-concordant treatment, 20.6% received treatment with minor deviations, 31.7% received treatment with major deviations, and 35.1% received no treatment. The risk of death in patients who received no cancer-directed therapy was 3.49 (95% CI, 1.83-6.66) times higher than in patients who received standard treatment or treatment with minor deviations. Similarly, the risk of death in patients from countries with a low HDI was 1.67 (95% CI, 1.07-2.62) times higher than in those from countries with a medium HDI. Overall survival at 1 and 3 years was 70.9% (95% CI, 65.5%-76.3%) and 45.3% (95% CI, 38.9%-51.7%), respectively. CONCLUSIONS: Fewer than 1 in 20 patients diagnosed with potentially curable CRC received standard of care in SSA, reinforcing the need to improve healthcare infrastructure, including the oncology and surgical workforce.

Prevalence and risk factors for tobacco, khat, and alcohol consumption among high school students in Ethiopia.

BACKGROUND: Tobacco, khat, alcohol, and marijuana are the main risk factors for non-communicable diseases. There are limited studies on substance use in Ethiopia, especially among secondary school students. This study aims to determine the epidemiology of substance use among secondary school students in Ethiopia. METHODS: This cross-sectional study was conducted in March 2020 in four large regions of Ethiopia and the capital Addis Ababa. We collected data from 3,355 grade 9 and grade 10 students in 36 randomly selected high schools. Data were collected on tobacco, khat, alcohol and other substances. Mixed effect logistic regression models were fitted to determine the predictors of cigarette smoking. RESULTS: 157 (4.7%) of the participants ever smoked cigarettes and 81 (2.4%) were current smokers. 106 (3.2%) ever used smokeless tobacco, 1,342 (41.8%) had ever drunk alcohol, 290 (8.7%) ever used khat, 137 (4.8%) chewed khat regularly and 76 (2.3%) ever used marijuana. There was a significant regional variation in substance use patterns; cigarette and khat use was the highest in southern regions, whereas alcohol use was highest in the northern areas. Availability of cigarette and khat shops within a 100-meter radius of the school compound was reported by 1,229 (37.5%) and 816 (25%) students, respectively. Three hundred fifty-four (10.9%) students had ever seen someone smoking a cigarette in the school compound. Ever use of smokeless tobacco (Adjusted Odds Ratio (AOR) = 9.4, 95%CI: 4.9-17.9), ever use of shisha (AOR = 8, 95% CI: 3.9-16.3), ever use of khat (AOR = 4.1, 95%CI: 2.5-6.8), ever use of alcohol (AOR = 2.3, 95%CI: 1.4-3.7), having a friend who smoked a cigarette (AOR = 2, 95%CI: 1.2-3.5), and ever seen someone smoking a cigarette in the school compound (AOR = 1.9, 95%CI: 1.1-3.4) were associated with ever use of cigarettes. CONCLUSION: Substance use prevalence in Ethiopia has regional variations and prevention strategies should be tailored to the needs of the regions. Although this study reported a lower prevalence of cigarette smoking, students could access cigarettes and khat in nearby school areas. The existing tobacco control laws that prohibit selling tobacco products to children and adolescents under 21 years of age and ban establishing tobacco shops close to school compounds should be enforced.

[Climate Crisis: What Gastrointestinal Complications of this Medical Emergency Should We Be Aware Of?] / Klimakrise: Welche gastroenterologischen Folgeerkrankungen dieses medizinischen Notfalls sollten wir kennen?

INTRODUCTION: The climate crisis has serious consequences for many areas of life. This applies in particular to human health - also in Europe. While cardiovascular, pneumological and dermatological diseases related to the climate crisis are often discussed, the crisis' significant gastroenterological consequences for health must also be considered. METHODS: A literature search (Pubmed, Cochrane Library) was used to identify papers with relevance particularly to the field of gastroenterology in (Central) Europe. Findings were supplemented and discussed by an interdisciplinary team. RESULTS: The climate crisis impacts the frequency and severity of gastrointestinal diseases in Europe due to more frequent and severe heat waves, flooding and air pollution. While patients with intestinal diseases are particularly vulnerable to acute weather events, the main long-term consequences of climate change are gastrointestinal cancer and liver disease. In addition to gastroenteritis, other infectious diseases such as vector-borne diseases and parasites are important in the context of global warming, heat waves and floods. DISCUSSION: Adaptation strategies must be consistently developed and implemented for vulnerable groups. Patients at risk should be informed about measures that can be implemented individually, such as avoiding heat, ensuring appropriate hydration and following hygiene instructions. Recommendations for physical activity and a healthy and sustainable diet are essential for the prevention of liver diseases and carcinomas. Measures for prevention and the promotion of resilience can be supported by the physicians at various levels. In addition to efforts fostering sustainability in the immediate working environment, a system-oriented commitment to climate protection is important.

Characteristics of Women Seeking Cervical Cancer Cytology Screening in a Private Health Facility.

Background and Objectives: Over 80% of cervical cancer cases in sub-Saharan Africa are detected at late stages, predominantly due to the lack or inaccessibility of prevention services. Public health facilities in Ethiopia offer free cervical cancer screening for eligible women. Besides the public health facilities, private providers also offer a variety of screening services at the patients' expense. As the overall cervical cancer screening uptake in Ethiopia is still far below the 90% WHO target, coordination between all actors of the health system is key. This includes a close cooperation between the public and private sectors to combine the advantages of both to the benefit of all patients as well as media campaigns and community involvement to promote the self-initiation of screening. Materials and Methods: To gain insights into the utilization of cervical cancer screening in the private health sector, we conducted an institution-based cross-sectional study at Arsho medical laboratories in Addis Ababa. Every woman who came there for cervical cancer screening between 1 May and 30 June 2020 was asked to participate in a questionnaire-based, face-to-face interview about their socio-demographic background, cervical cancer screening experience and self-initiation of screening. A total of 274 women participated in the interviews. We further assessed the reproductive status of the patients, their risk factors for cervical cancer, source of information about the screening and barriers to cervical cancer screening. Results: The ages of the participants ranged between 20-49 years. The majority (over 70%) were married. A total of 37.6% reported self-initiating the screening. More than three-quarters of all interviewed women reported mostly using the private health care sector for all kinds of health services. Conclusions: While the Ethiopian government efforts on scaling up cervical cancer screening focus mainly on public health facilities, the private sector often does not get as much attention from policy makers. Efforts should be made to extend the government's interest in cervical cancer screening and implementation research to the private healthcare sector.

Treatment guideline concordance, initiation, and abandonment in patients with non-metastatic breast cancer from the African Breast Cancer-Disparities in Outcomes (ABC-DO) cohort in sub-Saharan Africa: a prospective cohort study.

BACKGROUND: Comprehensive breast cancer management is essential to achieve high breast cancer survival; however, detailed reports of the treatment regimens received by patients are scarce in sub-Saharan Africa where survival is low. We aimed to examine treatment initiation, guideline concordance, and abandonment in patients with non-metastatic breast cancer in sub-Saharan Africa from the African Breast Cancer-Disparities in Outcomes (ABC-DO) prospective cohort. METHODS: The ABC-DO prospective cohort study recruited women (aged ≥18 years) with newly diagnosed invasive breast cancer in eight hospitals across five sub-Saharan African countries (Namibia, Nigeria, Uganda, South Africa, and Zambia). We analysed treatments received by women who were classified as non-metastatic (M0) at the initial presentation. Data on surgery, radiotherapy, and systemic therapies were obtained from medical records and a self-reported follow-up questionnaire at 6 months after the diagnosis, follow-up calls every 3 months, and a baseline questionnaire. Initiation, completion, and abandonment of treatment modalities and combined therapy regimens were examined overall, by country-specific groups, and by clinical factors relevant for guideline-based treatment. FINDINGS: Of 2313 women recruited into the ABC-DO study between Sept 10, 2014, and Dec 31, 2017, 2226 had histologically or clinically confirmed breast cancer. Of these 2226 women, 510 were excluded from the present analysis because 378 had metastatic disease, 37 were prevalent cases (defined as those previously diagnosed with breast cancer >2 years before baseline), 82 had unknown TNM stage, and 13 were White or Asian women in South Africa (number was too small for analysis). After a median follow-up of 5·2 years (IQR 4·6-5·9), 1163 (68%) of 1716 women underwent breast cancer surgery. Surgery and systemic therapy (ie, multimodality treatment) with radiotherapy was initiated in 370 (36%) of 1028 women with localised tumours versus 156 (23%) of 688 women with locally advanced tumours, whereas multimodality treatment without radiotherapy was initiated in 386 (38%) versus 167 (24%) women, respectively. Of 1530 patients requiring chemotherapy (which excludes 105 who died within 6 months after baseline), 1013 (66%) initiated treatment of neoadjuvant chemotherapy or surgery within 3 months after baseline, which was adequately completed by 359 (35%) of 1013 women, marginally completed by 284 (28%), abandoned by 200 (20%), and unknown in 151 (15%). 19 (2%) women died within 6 months after chemotherapy initiation. Of 1375 women in whom endocrine therapy was indicated, this treatment was initiated in 920, and lasted at least 3 years in 367 (40%) women. Treatment disparities between country-specific groups were substantial for all therapy regimens. INTERPRETATION: A high proportion of patients with non-metastatic breast cancer did not initiate, did not fully complete, or abandoned treatment with surgery, systemic therapy, radiotherapy, or an appropriate combination of these, highlighting the need for improved treatment access and completion in sub-Saharan Africa to potentially prevent premature breast cancer deaths.
