Oyesigye E, Cervini C, Mahuku G, Medina A. Potential Impact of Current Agricultural Practices on Mycotoxin Occurrence and Mycotoxin Knowledge Along the Cassava Value Chain in Uganda. J Food Prot 2024; 87:100340. [PMID: 39117180 DOI: 10.1016/j.jfp.2024.100340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 07/23/2024] [Accepted: 08/02/2024] [Indexed: 08/10/2024]
Abstract
Cassava is the second most important staple food crop for Uganda and is prone to contamination with mycotoxins. This study aimed at understanding the current agricultural practices, their potential influence on mycotoxin occurrence, as well as assessing mycotoxin knowledge among key cassava value chain actors, including farmers, wholesalers, and processors. Data were collected through individual interviews (210), key informant interviews (34), and 4 focus group discussions. The findings revealed that 51% of farmers peeled cassava directly on bare ground, resulting in direct contact with soil that potentially harbors mycotoxin-producing fungi, such as Aspergillus section Flavi. During postharvest handling, 51.6% of farmers dried cassava chips directly on bare ground. Nearly, all (95.2%) of wholesalers packed cassava chips in local gunny bags and placed them on ground instead of pallets. In the processing of cassava chips into flour, only one of the 14 processing machines was certified by the Uganda National Bureau of Standards. Additionally, there was only one processing machine available for every 180 (1:180) consumers bringing their cassava for processing. 50.8% of cassava consumers interviewed admitted to consuming cassava flour regardless of quality, while 73% blended cassava flour with flour from mycotoxin-susceptible crops mainly maize, millet, and sorghum. Most (96.2%) of the people along the cassava value chain did not understand what the term mycotoxins meant. However, 56% of interviewed respondents were familiar with the term aflatoxins. Of the cassava value chain actors aware of mycotoxins, 82.9% knew of methods for reducing aflatoxin contamination, but only 40.9% were putting such methods into practice. More farmers (47.9%) managed aflatoxins compared to wholesalers (33.3%) and processors (21.4%). Knowledge on aflatoxins was significantly associated with value chain actor (P = 0.026), head of household (P = 0.004), region (P = 0.033), age (P = 0.001), and experience (P = 0.001). This study highlights the critical areas of mycotoxin contamination within the cassava value chain in Uganda and underscores the need to improve the knowledge among value chain actors especially farmers.

Abstract
In sub-Saharan Africa, colorectal cancer (CRC) has historically been considered a rare disease, although some previous studies have suggested that the incidence is increasing. We examine time trends in the incidence of CRC using data from 12 population-based cancer registries in 11 countries of sub-Saharan Africa that were able to provide time series data for periods of 12 or more years, or with earlier data with which recent rates may be compared. Age-standardized incidence rates were highest in the higher-income countries, and were increasing in all of the populations studied, and these increases were statistically significant in all but three. Current evidence has suggested a link between the increased adoption of western lifestyle habits with colorectal cancer, and along with increasing urbanization of African populations, there is an increase in body weight, as well as evidence of increasing consumption of meat, sugars, and alcohol.

Wismayer R, Kiwanuka J, Wabinga H, Odida M. Dietary risk factors for colorectal cancer in Uganda: a case-control study. BMC Nutr 2024; 10:88. [PMID: 38898481 PMCID: PMC11186163 DOI: 10.1186/s40795-024-00894-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2022] [Accepted: 06/05/2024] [Indexed: 06/21/2024] Open
Abstract
INTRODUCTION Low-income countries in East Africa have a lower incidence of colorectal cancer (CRC) than high-income countries; however, the incidence has steadily increased in the last few decades. In Uganda, the extent to which genetic and environmental factors, particularly dietary factors, contribute to the aetiology of CRC is unclear. Therefore, the objective of our study was to determine the relationship between dietary factors and CRC in Uganda. METHODS We conducted a case-control study and recruited 128 cases and 256 controls, matched for age (± 5 years) and sex. Data regarding the frequency of consumption of the dietary factors were obtained from all the participants using an interview-based questionnaire. The potential dietary risk factors and protective factors evaluated included the type and frequency of meat consumed and the type and frequency of high-fibre foods consumed. The frequency was either 4 or more times/week, 2-3 times/week, once/week or never. Conditional logistic regression analyses were used to determine the odds ratios associated with the different risk and protective factors. RESULTS The median age (IQR) for the case participants was 55.5 (43-67.5) years, and that of the control participants was 54 (42-65) years. The male-to-female ratio was 1:1 for all the participants. Factors significantly associated with CRC cases included:- the consumption of boiled beef 2-3 times/week (aOR:3.24; 95% CI: 1.08-9.69; p < 0.035). Consumption of high-fibre foods, including:- millet for ≥ 4 times/week (aOR: 0.23; 95% CI: 0.09-0.62; p = 0.003)), spinach for ≥ 4 times/week (aOR:0.32; 95% CI: 0.11-0.97; p = 0.043), and potatoes 2-3 times/week (aOR: 0.30; 95% CI: 0.09-0.97; p = 0.044), were protective against CRC. Boiled cassava showed a tendency to reduce the likelihood of CRC when consumed ≥ 4 times/week (aOR:0.38; 95% CI: 0.12-1.18) however this did not reach statistical significance (p = 0.093). CONCLUSIONS The consumption of boiled beef increases the risk of CRC, while the intake of high-fibre foods may reduce the risk of CRC among Ugandans. We recommend nutritional educational programmes to increase public awareness regarding the protective role of a high-fibre diet and to limit the intake of cooked meat in our Ugandan population.

Ecancermedicalscience 2024; 18:1688. [PMID: 38566768 PMCID: PMC10984836 DOI: 10.3332/ecancer.2024.1688] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Indexed: 04/04/2024] Open
Abstract
Introduction Cancer is the second leading cause of mortality with over 19 million cases and 10 million deaths worldwide. Available data on cancer patterns in Uganda are through modelling of data from two population-based cancer registries (PBCRs) representing only about 10% of the cancer situation in Uganda. This study sought to determine the common types of cancer among adults and children in Arua District over a 5-year period (2017-2021). Methods Retrospective cohort chart review and 'catchment population approach' were employed. All newly diagnosed cancer patients from Arua between 2017 and 2021 were included in this study. Data were collected using Redcap whereas management and analysis were conducted using Stata 17. Cancer patterns were computed as frequencies and percentages and the interest was in finding out the common cancers among adults (above 19 years) and children (0-19 years). Results Over the 5-year study period, a total of 1,118 new cancer cases were registered, with slightly more females (52.1%). The top five common cancers irrespective of sex and age were: liver cancer (13.7%), cervical (11.8%), breast (10.7%), oesophagus (10.5%) and Burkitt's lymphoma (BL) (6.4%). In this study, 15.3% (n = 171) of the study participants were children. The top five common childhood cancers included BL (42%), leukemia (10.5%), other lymphomas (9.4%), osteosarcoma (4.7%) and nephroblastoma (3%). Conclusion There is a high incidence of liver cancer in Arua district. The high levels of cervical, breast and oesophagus cancer were consistent with what is reported by the two PBCRs in Uganda. However, BL could be due to the presence of a BL treatment centre at Kuluva hospital in Arua. Cancer interventions in Arua should therefore be targeted towards liver, cervix, breast, and oesophagus cancer and furthering research on the reason for the high incidence of liver cancer.

Abstract
Introduction Gastric cancer (GC) is the third leading cause of global cancer-related mortality. Despite the shifting burden of GC to low-and middle-income countries, the data regarding incidence, treatment, and outcomes in these settings are sparse. The primary aim of this systematic review was to aggregate all available data on GC in sub-Saharan Africa (SSA) to describe the variability in incidence across the region. Methods Studies reporting population-based primary data on GC in SSA were considered. The inclusion was limited to primary studies published between January 1995 and March 2022 which comprised of adult patients in SSA with GC. Studies without accessible full text in either French or English language were excluded. Unadjusted GC incidence rates with their standard errors for each study were recalculated from the crude numerators and denominators provided in individual studies. Results A total of 5,626 articles were identified in the initial search, of which, 69 studies were retained. Reported incidence rates ranged from a high of 5.56 GC cases per 100,000 in Greater Meru Kenya to a low of 0.04 GC cases per 100,000 people in Benin City Nigeria. The overall crude pooled incidence was 1.20 GC cases per 100, 000 (95%CI 1.15-1.26) with a variability of 99.83% (I2 p < 0.001). From the 29 high-quality population-based registry studies the crude pooled incidence was 1.71 GC cases per 100,000 people (95%CI 1.56-21.88) with a variability of 99.60%. Conclusion This systemic review demonstrates that GC incidence is highly variable across SSA. The limited data on GC treatment, mortality, and survival presents a significant challenge to providing a complete epidemiologic description of the burden of GC in SSA. There is a need for further robust data collection, exploration, and research studies on cancer care in SSA, with continued assessment of primary data availability.

Abstract
An estimated 38 million people live with human immunodeficiency virus (HIV) worldwide and are at excess risk for multiple cancer types. Elevated cancer risks in people living with HIV (PLWH) are driven primarily by increased exposure to carcinogens, most notably oncogenic viruses acquired through shared transmission routes, plus acceleration of viral carcinogenesis by HIV-related immunosuppression. In the era of widespread antiretroviral therapy (ART), life expectancy of PLWH has increased, with cancer now a leading cause of co-morbidity and death. Furthermore, the types of cancers occurring among PLWH are shifting over time and vary in their relative burden in different parts of the world. In this context, the International Agency for Research on Cancer (IARC) and the US National Cancer Institute (NCI) convened a meeting in September 2022 of multinational and multidisciplinary experts to focus on cancer in PLWH. This report summarizes the proceedings, including a review of the state of the science of cancer descriptive epidemiology, etiology, molecular tumor characterization, primary and secondary prevention, treatment disparities and survival in PLWH around the world. A consensus of key research priorities and recommendations in these domains is also presented.

Abstract
The burden of digestive cancers is increasing worldwide. The Global Cancer Observatory (GLOBOCAN) 2020 and the Global Burden of Disease (GBD) 2019 are two primary cancer databases, which have a significant impact on policy formulation and resource allocation. We aim to compare the incidence and mortality of digestive cancers between them. Digestive cancer (esophageal, stomach, colorectal, liver, gallbladder and pancreatic cancer) incidence was obtained from the Cancer Today and GBD 2019 result tool. The top five countries with the most or minor difference between GLOBOCAN 2020 and GBD 2019 in age-standardized incidence rates (ASIRs) of digestive cancers were identified. A systematic search on the incidence of specific digestive cancer in selected countries from PubMed and Embase was conducted, and 20 of 281 publications were included. The most significant differences in digestive cancers incidence were commonly found in Asian countries (70%), particularly Indonesia, Vietnam and Myanmar, located in Southeast Asia. The ASIRs for most digestive cancers, except liver cancer, in GLOBOCAN 2020 were higher than those in GBD 2019. Gallbladder cancer had the highest average ratio, followed by liver cancer. The most commonly used standard population was Segi's standard population, followed by the World Health Organization standard population. The data sources nor the processing methods of GLOBOCAN 2020 and GBD 2019 were not similar. Low- and middle-income countries without population-based cancer registries were more likely to have selection bias in data collection and amplify regional variations of etiological factors. Better judgments on the quality of cancer data can be made.

Abstract
BACKGROUND New models of care are required to support women with breast cancer due to rising incidence and mortality in sub-Saharan Africa (SSA). This study gives voice to the experiences of advanced-stage breast cancer patients in the Botswana healthcare system, to guide improved service provision and the potential utility of patient navigator (PN) programs. METHODS focus group discussions (FGD) were conducted with advanced-stage breast cancer patients recruited from the oncology ward of the public Princess Marina Hospital located in Gaborone, Botswana. RESULTS FGDs included 7 female breast cancer patients and their 7 caregivers (2 male and 5 females). Findings fell into the following themes: experiences with cancer diagnosis, experiences with treatment, roles of caregivers, information needs, views on cancer resources, and attitudes towards cancer research. The study identified several barriers across the cascade of care for breast cancer patients in the Botswana health system. These correspond to challenges with timely diagnosis and comprehensive management and highlight community level barriers to achieving the targets of the WHO Global Breast Cancer initiative (GBCI). CONCLUSION The study findings suggest PN programs have the potential to bridge barriers identified in the Botswana healthcare system by improving communication, meeting information needs, providing emotional or practical support, and by addressing logistical barriers to cancer diagnosis and treatment in Botswana.

[PMID: 37734800 DOI: 10.1016/s2214-109x(23)00349-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Revised: 06/29/2023] [Accepted: 07/13/2023] [Indexed: 09/23/2023]
Abstract
BACKGROUND Kaposi sarcoma is a rare, possibly angioproliferative, tumour. Kaposi sarcoma is one of the most common cancers in people living with HIV and poses a serious public health challenge in regions with high HIV burden. We aim to describe global patterns and population-wide trends in the burden of Kaposi sarcoma. METHODS In this population-based study, the incidence and mortality estimates of Kaposi sarcoma from 185 countries and regions in 2020 were extracted from the GLOBOCAN 2020 database. The time trends in Kaposi sarcoma incidence were evaluated using the cancer registry data from Cancer Incidence in Five Continents plus from 1998 to 2012. We did not apply any inclusion or exclusion criteria to the data used in this study. Joinpoint regression was used to evaluate the average annual percentage change (AAPC) to quantify trends in the age-standardised incidence rate (ASIR) of Kaposi sarcoma. Correlation analysis was used to evaluate the relationship between the ASIR or age-standardised mortality rate (ASMR) and Human Development Index (HDI). FINDINGS In 2020, the global estimated ASIR of Kaposi sarcoma was 0·39 (per 100 000 people), with an estimated 34 270 newly diagnosed cases (23 413 males and 10 857 females). An estimated 15 086 Kaposi sarcoma deaths were reported (9929 males and 5157 females), corresponding to an ASMR of 0·18 (per 100 000 people). In 2020, Africa accounted for 73·0% (25 010 of 34 270) of the incidence and 86·6% (13 066 of 15 086) of the deaths from Kaposi sarcoma worldwide. There was a significant correlation between the ASIR or ASMR and HDI. The incidence of Kaposi sarcoma increased in males in both Türkiye and the Netherlands. The AAPC was 11·5% (95% CI 3·2-20·4) for males in Türkiye and 2·5% (1·1-3·9) for males in the Netherlands from 1998 to 2012. The incidence of Kaposi sarcoma decreased in White Americans, Israel, Uganda, Costa Rica, Colombia, Canada, and Denmark, from 1998 to 2012. INTERPRETATION Kaposi sarcoma is a relatively rare cancer worldwide but is endemic in some countries in southern and eastern Africa. Addressing disparities in health-care resource allocation and improving HIV/AIDS care across different HDI regions might contribute to the prevention of Kaposi sarcoma.

Estimating cancer incidence in Uganda: a feasibility study for periodic cancer surveillance research in resource limited settings. BMC Cancer 2023; 23:772. [PMID: 37596529 PMCID: PMC10436406 DOI: 10.1186/s12885-023-11124-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 06/28/2023] [Indexed: 08/20/2023] Open
Abstract
BACKGROUND Population based cancer registries (PBCRs) are accepted as the gold standard for estimating cancer incidence in any population. However, only 15% of the world's population is covered by high quality cancer registries with coverage as low as 1.9% in settings such as Africa. This study was conducted to assess the operational feasibility of estimating cancer incidence using a retrospective "catchment population" approach in Uganda. METHODS A retrospective population study was conducted in 2018 to identify all newly diagnosed cancer cases between 2013 and 2017 in Mbarara district. Data were extracted from the medical records of health facilities within Mbarara and from national and regional centres that provide cancer care services. Cases were coded according to the International Classification of Diseases for Oncology (ICD-0-03). Data was analysed using CanReg5 and Excel. RESULTS We sought to collect data from 30 health facilities serving Mbarara district, southwestern Uganda. Twenty-eight sources (93%) provided approval within the set period of two months. Among the twenty-eight sources, two were excluded, as they did not record addresses for cancer cases, leaving 26 sources (87%) valid for data collection. While 13% of the sources charged a fee, ranging from $30 to $100, administrative clearance and approval was at no cost in most (87%) data sources. This study registered 1,258 new cancer cases in Mbarara district. Of the registered cases, 65.4% had a morphologically verified diagnosis indicating relatively good quality of data. The Age-Standardised Incidence Rates for all cancers combined were 109.9 and 91.9 per 100,000 in males and females, respectively. In males, the most commonly diagnosed cancers were prostate, oesophagus, stomach, Kaposi's sarcoma and liver. In females, the most common malignancies were cervix uteri, breast, stomach, liver and ovary. Approximately, 1 in 8 males and 1 in 10 females would develop cancer in Mbarara before the age of 75 years. CONCLUSION Estimating cancer incidence using a retrospective cohort design and a "catchment population approach" is feasible in Uganda. Periodic studies using this approach are potentially a precious resource for producing quality cancer data in settings where PBCRs are scarce. This could supplement PBCR data to provide a detailed and comprehensive picture of the cancer burden over time, facilitating the direction of cancer control efforts in resource-limited countries.

Abstract
Background Studies have shown that prostate cancer (PCa) is increasing at a rate of 5.2% per annum in Uganda and as few as 5% of men have ever been screened for PCa in Uganda. The situation may be worse among male prisoners given their 'vulnerable status'. The goal of this study was to examine the perceptions, attitudes and beliefs of men in Ugandan prisons regarding barriers to and facilitators of PCa screening. This would enable the identification of potential interventional strategies to promote PCa screening among men in Ugandan prisons. Methods This study applied the explanatory sequential mixed methods study design. We first conducted 20 focus group discussions and 17 key informant interviews. The qualitative data were analysed to enrich a survey among 2,565 prisoners selected using a simple random sampling technique. Results Qualitatively, the belief that all cancers have no cure was a barrier against most participants considering screening to be of any value, coupled with the fear of screening positive for PCa and the associated stress. In addition, poor PCa knowledge and lack of PCa screening services in prisons were perceived as barriers to PCa screening in prison settings.The quantitative data from the survey of 2,565 participants with a mean age of 50.2 (9.8), indicated that the main barriers to PCa screening were mainly myths, beliefs, lack of screening facilities and technical capacity. The majority believed that creating PCa awareness, conducting screening outreach in prisons, and providing equipment for PCa screening in prisons health facilities will facilitate PCa screening, as well as working with the Uganda prison service to train the prison health staff to perform PCa screen to facilitate Prison Health Centres capacity to screen for PCa. Conclusion There is a need to develop interventions to increase awareness among the inmates in the prison health system, while ensuring that the prison health facilities are equipped with the required screening logistics, backed with outreaches from cancer-specialised hospitals/facilities.

Abstract
Introduction Globally, colorectal cancer (CRC) is the third most common malignancy and the second most common cause of cancer death. By 2030, the incidence is expected to increase to reach 2.2 million cases and 1.1 million deaths. In Sub-Saharan Africa, accurate cancer incidence data is limited, but anecdotally, clinicians note a significant rise in the incidence of CRC in the past decade. To educate clinicians on the growing burden of CRC, the Tanzanian Surgical Association hosted a 4-day CRC symposium from 3rd to 6th October 2022. Following the meeting, a group of multidisciplinary stakeholders created a working group whose first task was to assess the epidemiology, presentation and available resources for CRC care in Tanzania. The findings of that assessment are described in this article. Findings The true incidence of CRC in Tanzania is currently unknown. However, individual high-volume centres have noted a dramatic rise in cases of colon and rectal cancer on their wards. A review of the published data on CRC in Tanzania showed that most patients present with CRC late and the limited availability of endoscopic and diagnostic services poses a challenge for accurately staging these patients prior to treatment. Multidisciplinary care, including surgery, chemotherapy and radiation, is available for the treatment of CRC in Tanzania, although the capacity and quality of these services vary throughout the country. Conclusion There is a substantial burden of CRC in Tanzania that appears to be increasing. While there is capacity in the country to provide all aspects of multidisciplinary care, late presentation, limited access to diagnostic and treatment services and poor coordination continue to be significant barriers to providing optimal treatment to these patients.

Abstract
BACKGROUND Although reproductive failure after cancer treatment in children and young adults has been extensively described in high-income countries, there is a paucity of data in low-income settings. In addition, patient, parent, or health worker experiences, perspectives, and attitudes toward the risk of reproductive failure among young cancer patients in these settings are unknown. This study will describe the extent of reproductive morbidity associated with cancer treatment among childhood and young adult cancer survivors in Uganda. In addition, we aim to explore the contextual enablers and barriers to addressing cancer treatment-related reproductive morbidity in Uganda. METHODS This is an explanatory sequential mixed-method study. The quantitative phase will be a survey among childhood and young adult cancer survivors recruited from the Kampala Cancer Registry (KCR). The survey will utilize a Computer Assisted Telephone Interview (CATI) platform on a minimum of 362 survivors. The survey will obtain information on self-reported reproductive morbidity and access to oncofertility care. The qualitative phase will use grounded theory to explore contextual barriers and enablers to addressing reproductive morbidity associated with cancer treatment. The quantitative and qualitative phases will be integrated at the intermediate and results stage. CONCLUSION Results from this study will inform the development of policy, guidelines, and programs supporting reproductive health among childhood and young adult cancer survivors.

Abstract
OBJECTIVE As antiretroviral therapy (ART) has been widely scaled up in Rwanda, life expectancies among people with HIV (PWH) have increased. With increasing viral suppression, AIDS-defining cancers (ADCs) typically decrease; however, as the PWH population ages, non-AIDS-defining cancers (NADCs) will be expected to increase. The aim of this study was to compare cancer diagnoses between PWH and patients without HIV in Rwanda and to describe the changes in the number and types of cancer over time. DESIGN Retrospective cohort study. METHODS Rwanda National Cancer Registry (RNCR) recorded the HIV status, primary site, and morphological description for cancer diagnoses from 2007 to 2018. Descriptive analyses were carried out by cancer group (HIV+ and HIV-). A portion of patients whose HIV status was unknown (63%) were excluded from the present analysis. RESULTS Among the 20 258 cases registered in the Registry, there were 1048 PWH and 6359 HIV- individuals. The proportion of ADCs were significantly higher in the PWH group compared to those without HIV ( P < 0.001). Among PWH, there was a longitudinal increase in NADCs and a decrease in ADCs ( P < 0.001) over time. Among the ADCs in the PWH group, there was a significant decline in Kaposi sarcoma cases over time. CONCLUSIONS The study demonstrates a decreasing frequency of ADCs driven by declines in Kaposi sarcoma diagnoses and an increased frequency of NADCs among PWH in Rwanda over time. These findings support a need for focusing early detection and management efforts on NADCs, as they begin to play a larger role in the disease processes that affect the aging PWH population.

Potential New Approaches for Prostate Cancer Management in Resource-Limited Countries in Africa. Ann Glob Health 2023; 89:14.

Abstract
Prostate cancer is a major male malignancy in many sub-Saharan countries in Africa. Because of resource limitations, screening, early detection, diagnosis, and curative treatments are not available for many men on the subcontinent, and there are even barriers to the treatment of advanced-stage metastatic prostate cancer. We are making the case for new approaches to the detection, diagnosis, and treatment of this malignancy in sub-Saharan Africa and other low-resource regions-approaches that differ from the ones available and used in high-income countries. The development of one-step dipstick-type detection assays of serum prostate-specific antigen (PSA) offers an approach to prostate cancer detection, treatment and monitoring that circumvents issues related to laboratory quality control and is also low-cost. Curative-intent treatments of early-stage prostate cancer are often unavailable in low-resource contexts, and most prostate cancers are not detected in Africa until they are at an advanced stage. Hence, androgen deprivation treatments, including orchiectomy and older low-cost drugs, offer feasible and affordable approaches to prolong survival and sustain a reasonable quality of life. However, clinical trials are needed to identify which of these androgen deprivation treatments are most efficacious and best tolerated to make progress in providing medical care for men with prostate cancer in sub-Saharan Africa and other low- and lower-middle-income areas around the world.

Abstract
Introduction The incidence of colorectal cancer (CRC) is increasing in East Africa. Changes in lifestyle and dietary changes, particularly alcohol consumption, smoking, and consumption of cooked meats with a reduction in fibre in the diet may be responsible. The objective of our study was to determine the risk factors responsible for CRC in Uganda. Methods We recruited 129 participants with histologically proven colorectal adenocarcinoma and 258 control participants from four specialized hospitals in central Uganda from 2019 to 2021. Controls were block matched for age (±5 years) and sex of the case participants. The risk factor variables included; area of residence, tribe, body mass index (BMI), smoking, alcohol consumption and family history of gastrointestinal cancer. We used conditional or ordinal logistic regression to obtain crude and adjusted odds ratios for risk factors associated with CRC. Results In bivariate analysis, case participants were more likely to be associated with urban residence (cOR:62.11; p<0.001); family history of GI cancer (cOR: 14.34; p=0.001); past smokers (cOR: 2.10; p=0.080); past alcohol drinkers (cOR: 2.35; p=0.012); current alcohol drinkers (cOR: 3.55; p<0.001); high BMI 25–29.9 kg/m2 (cOR: 2.49; p<0.001); and high BMI ≥30kg/m2 (cOR: 2.37; p=0.012). In the multivariate analysis, urban residence (aOR: 82.79; p<0.001), family history of GI cancer (aOR: 61.09; p<0.001) and past smoking (aOR: 4.73; p=0.036) were independently associated with a higher risk of developing CRC. Conclusion A family history of gastrointestinal cancer was a risk factor for CRC. While population-based CRC screening may not be feasible in low income-countries, targeted CRC screening for first-degree relatives with CRC should be considered in East Africa. Molecular genetic studies need to be carried out to determine the role of hereditary factors in our population. Prevention strategies should be adopted to avoid smoking in our population which was associated with an increased risk of CRC.

Abstract
Background Clinical trials are increasingly perceived as a therapeutic opportunity for cancer patients. Favoring their concentration in few high-expertise academic centers maximizes quality of data collection but poses an issue of access equality. Analytical tools to quantify trial accessibility are needed to rationalize resources. Materials and methods We constructed a distance-based accessibility index (dAI) using publicly available data on demographics, cancer incidence and trials. Multiple strategies were applied to mitigate or quantify clear sources of bias: reporting biases by text mining multiple registries; reliability of simple geographical distance by comparison with high-quality travel cost data for Italy; index inflation due to highly heterogeneous cancer incidence by log-transformation. We studied inequalities by Gini index and time trend significance by Mann–Kendall test. We simulated different resource allocation models in representative countries and identified locations where new studies would maximally improve the national index. Results The dAI approximated well a more realistic but not widely applicable travel cost-based index. Accessibility was unevenly distributed across and within countries (Gini index ∼0.75), with maximal inequalities in high- and upper-middle-income countries (China, United States, Russian Federation). Over time, accessibility increased but less than the total number of trials, most evidently in upper-middle-income countries. Simulations in representative countries (Italy and Serbia) identified ideal locations able to maximally raise the national index. Conclusions Access to clinical trials is highly uneven across and within countries and is not mitigated by simple increase in the number of trials; a rational algorithmic approach can be used to mitigate inequalities. Accessibility to cancer clinical trials grew less than total number of trials over time in upper-middle-income countries. Accessibility is unevenly distributed, with maximal inequalities in high- and upper-middle-income countries. Simulation of resource allocation can identify ideal locations able to raise the national accessibility index.

Abstract
BackgroundCancer remains a major public health problem, especially in Sub-Saharan Africa (SSA) where the provision of health care is poor. This scoping review mapped evidence in the literature regarding the burden of cervical, breast and prostate cancers in SSA.MethodsWe conducted this scoping review using the Arksey and O'Malley framework, with five steps: identifying the research question; searching for relevant studies; selecting studies; charting the data; and collating, summarizing, and reporting the data. We performed all the steps independently and resolved disagreements through discussion. We used Endnote software to manage references and the Rayyan software to screen studies.ResultsWe found 138 studies that met our inclusion criteria from 2,751 studies identified through the electronic databases. The majority were retrospective studies of mostly registries and patient files (n = 77, 55.8%), followed by cross-sectional studies (n = 51, 36.9%). We included studies published from 1990 to 2021, with a sharp increase from 2010 to 2021. The quality of studies was overall satisfactory. Most studies were done in South Africa (n = 20) and Nigeria (n = 17). The majority were on cervical cancer (n = 93, 67.4%), followed by breast cancer (67, 48.6%) and the least were on prostate cancer (48, 34.8%). Concerning the burden of cancer, most reported prevalence and incidence. We also found a few studies investigating mortality, disability-adjusted life years (DALYs), and years of life lost (YLL).ConclusionsWe found many retrospective record review cross-sectional studies, mainly in South Africa and Nigeria, reporting the prevalence and incidence of cervical, breast and prostate cancer in SSA. There were a few systematic and scoping reviews. There is a scarcity of cervical, breast and prostate cancer burden studies in several SSA countries. The findings in this study can inform policy on improving the public health systems and therefore reduce cancer incidence and mortality in SSA.

Abstract
Background Cervical cancer (CxCa) incidence in Uganda is three times the global average and a leading cause of mortality for women. While there is funding and infrastructure to support HIV control in Uganda, these are not in place for CxCa prevention and control. This study was conducted to explore the knowledge and perceptions of HIV professionals in Uganda to identify perceived barriers and facilitators to CxCa screening and treatment among women living with HIV (WLHIV) as a basis to guide and inform policies and programs for CxCa prevention and control, including service integration. Methods This study used qualitative interviews to obtain primary data from professionals working in the HIV field in Uganda conducted from September 2020 to January 2022. Participants were identified through purposive and snowball sampling and consulted with colleagues at local service and academic agencies in Kampala. Both written and verbal informed consent was obtained. Hour-long interviews were conducted virtually and in person and recorded. Interviews consisted of open-ended questions exploring perspectives on, knowledge about, and practices surrounding HPV and CxCa among WLHIV in Uganda. Transcripts were analyzed and coded via MAXQDA software to identify facilitators and barriers to HPV vaccination, CxCa screening and treatment. Results Fifty key informant (KI) interviews were conducted. Analysis revealed two themes regarding priorities for cervical cancer policy in Uganda after KIs reflected on improving barriers to CxCa care. These were: (1) decentralization of care through integration of services and (2) leadership on a national level by increasing funding and organizing advocacy initiatives. Practical recommendations identified by KI that derived from these themes included leveraging community institutions and mass media campaigns to target misconceptions surrounding screening, making CxCa screening opt-out and integrated with HIV care, strengthening a centralized database, organizing mass roll-out of self-testing, and organizing training of healthcare workers. Conclusions Key informants call for solutions that address individual, community, and national barriers of cervical cancer care and emphasize the need for a strong national cervical cancer policy to coordinate currently fragmented services and the political will to adequately fund these.

Infection-related and lifestyle-related cancer burden in Kampala, Uganda: projection of the future cancer incidence up to 2030. BMJ Open 2022; 12:e056722.

Abstract
OBJECTIVES In Uganda, infection-related cancers have made the greatest contribution to cancer burden in the past; however, burden from lifestyle-related cancers has increased recently. Using the Kampala Cancer Registry data, we projected incidence of top five cancers, namely, Kaposi sarcoma (KS), cervical, breast and prostate cancer, and non-Hodgkin's lymphoma (NHL) in Uganda. DESIGN Trend analysis of cancer registry data. SETTING Kampala Cancer Registry, Uganda. MAIN OUTCOME MEASURE Cancer incidence data from 2001 to 2015 were used and projected to 2030. Population data were obtained from the Uganda Bureau of Statistics. Age-standardised incidence rates (ASRs) and their trends over the observed and projected period were calculated. Percentage change in cancer incidence was calculated to determine whether cancer incidence changes were attributable to cancer risk changes or population changes. RESULTS It was projected that the incidence rates of KS and NHL continue to decrease by 22.6% and 37.3%, respectively. The ASR of KS was expected to decline from 29.6 per 100 000 population to 10.4, while ASR of NHL was expected to decrease from 7.6 to 3.2. In contrast, cervical, breast and prostate cancer incidence were projected to increase by 35.3%, 57.7% and 33.4%, respectively. The ASRs of cervical and breast were projected to increase up to 66.1 and 48.4 per 100 000 women. The ASR of prostate cancer was estimated to increase from 41.6 to 60.5 per 100 000 men. These changes were due to changes in risk factors and population growth. CONCLUSION Our results suggest a rapid shift in the profile of common cancers in Uganda, reflecting a new trend emerging in low/middle-income countries. This change in cancer spectrum, from infection-related to lifestyle-related, yields another challenge to cancer control programmes in resource-limited countries. Forthcoming cancer control programmes should include a substantial focus on lifestyle-related cancers, while infectious disease control programmes should be maintained.

Abstract
Introduction Colorectal cancer (CRC) is the most common type of gastrointestinal malignancies and the third leading cause of cancer-related deaths for both sexes worldwide. Although the burden of CRC is highest in developed countries, reports are indicating a rise in the incidence of early-onset CRC in developing countries. In this study, we aimed to determine the prevalence of CRC among patients hospitalized with lower gastrointestinal complaints at a tertiary health facility in Uganda. Methods We conducted a 10-year retrospective chart review of patients admitted to Mulago National Referral Hospital in Kampala, Uganda, between 1st January 2010 and 31st December 2020. We reviewed all charts of patients admitted to the lower gastrointestinal tract (GIT) ward. Charts with grossly missing data, pediatric patients, and those from other non-lower GIT specialties were excluded. Results Data of 1476 unique eligible patients were analyzed. Of these,138 had a diagnosis of CRC (prevalence: 9.3%, 95% confidence interval (95% CI): 6.5-11.7%). Among patients with CRC, the female:male ratio was 1:1. The most common site for CRC was the rectum (59.8%, n= 79). For the 138 participants with CRC, 44 had staging data with 72.8% (n=32) having advanced disease, that is, stage 3 or 4. Factors independently associated with CRC were age ≥50 years (adjusted odds ratio (aOR): 4.3, 95% CI: 2.6-7.1, p < 0.001), female sex (aOR: 1.8, 95% CI: 1.2 -2.8, p = 0.005), being widowed (aOR: 2.5, 95% CI: 1.3-5.0, p = 0.006), and presence of any risk factor for CRC (aOR: 5.3, 95% CI: 2.9-9.9, p < 0.001). Conclusion CRC is relatively common among patients hospitalized with lower GIT complaints, particularly among women and those with known risk factors for CRC. Awareness creation and screening programs should be instituted to allow early diagnosis of CRC in our setting.

Trends in childhood cancer incidence in sub-Saharan Africa: Results from 25 years of cancer registration in Harare (Zimbabwe) and Kyadondo (Uganda). Int J Cancer 2021; 149:1002-1012. [PMID: 33945631 DOI: 10.1002/ijc.33619] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Revised: 03/11/2021] [Accepted: 03/26/2021] [Indexed: 11/10/2022]
Abstract
We examined trends in childhood cancer incidence in sub-Saharan Africa using data from two population-based cancer registries in Harare (Zimbabwe) and Kyadondo (Uganda) with cases classified according to the International Classification of Childhood Cancer and explored reasons for observed variations and changes. Over the whole 25-year period (1991-2015) studied, there were only small, and nonsignificant overall trends in incidence. Nevertheless, within the period, peaks in incidence occurred from 1996 to 2001 in Harare (Zimbabwe) and from 2003 to 2006 in Kyadondo (Uganda). Kaposi sarcoma and non-Hodgkin lymphoma accounted for the majority of the cases during these periods. These fluctuations in incidence rates in both registries can be linked to similar trends in the prevalence of HIV, and the availability of antiretroviral therapy. In addition, we noted that, in Harare, incidence rates dropped from 2003 to 2004 and 2007 to 2008, correlating with declines in national gross domestic product. The results indicate that the registration of childhood cancer cases in resource-poor settings is linked to the availability of diagnostic services mediated by economic developments. The findings highlight the need for specialised diagnostic and treatment programmes for childhood cancer patients as well as positive effects of HIV programmes on certain childhood cancers.
