RESUMO

INTRODUCTION: There is lack of diagnostic and treatment resources with variable access to childhood cancer treatment in low- and middle-income countries (LMIC), which may lead to subsequent poor survival. The primary aim of this study was to determine the prevalence and types of traditional and complementary medicine (T&CM) used in Cameroon. Secondarily, we explored determinants of T&CM use, associated costs, perceived benefits and harm, and disclosure of T&CM use to medical team. METHODS: A prospective, cross-sectional survey among parents and carers of children younger than 15 years of age who had a cancer diagnosis and received cancer treatment at three Baptist Mission hospitals between November 2017 and February 2019. RESULTS: Eighty participants completed the survey. Median patient age was 8.1 years (IQR4.1-11.1). There was significant availability (90%) and use (67.5%) of T&CM, whereas 24% thought T&CM would be good for cancer treatment. Common T&CM remedies included herbs and other plant remedies or teas taken by mouth, prayer for healing purposes and skin cutting. Living more than five hours away from the treatment center (P = 0.030), anticipated costs (0.028), and a habit of consulting a traditional healer when sick (P = 0.006) were associated with the use of T&CM. T&CM was mostly paid for in cash (53.7%) or provided free of charge (29.6%). Of importance was the fact that nearly half (44%) did not want to disclose the use of TM to their doctor. CONCLUSION: Pediatric oncology patients used T&CM before and during treatment but were unlikely to disclose its use to the child's health care team.

RESUMO

INTRODUCTION: The International Society of Paediatric Oncology-Paediatric Oncology in Developing Countries (SIOP-PODC) group recommended graduated-intensity retinoblastoma treatment for children in low- and middle-income countries with limited local resources. AIM: The aim was to improve outcome of children with retinoblastoma by means of a treatment protocol for low-income settings as recommended by the SIOP-PODC recommendation in Cameroon. METHODS: Children diagnosed with retinoblastoma between 2012 and 2016 were treated in two Baptist Mission hospitals in Cameroon, staging according to the International Retinoblastoma Staging System. Treatment included local therapy and combination chemotherapy (vincristine, cyclophosphamide, and doxorubicin) with or without surgery as per SIOP-PODC guidelines for low-income countries. Endpoint was survival at 24 months. Kaplan-Meier curves with log-rank (Mantel-Cox) chi-square (χ2 ) with respective p-values were prepared. RESULTS: Eighty-two children were included, of whom 79.3% had unilateral disease. The majority were males (61.0%) with median age 24 months (range 1-112 months; standard deviation [SD] 19). Limited disease was diagnosed in 58.5%, metastatic disease in 35.4%, and unknown stage in 6.1%. Overall survival (OS) was 50.0% at 24 months post diagnosis, but 68.8% for limited disease. Estimated cumulative survival at 24 months was 0.528 (standard error [SE] 0.056). Causes of death included disease progression/relapses (60.5%), neutropenic sepsis (15.9%), unknown causes (18.4%), unrelated infection (2.6%), and death post surgery (2.6%). Stage was significantly associated with OS (p < .001). CONCLUSION: Stage was the most significant factor for good OS and demonstrated the efficacy and feasibility of the SIOP-PODC-proposed management guidelines for retinoblastoma in a lower middle-income setting.

RESUMO

BACKGROUND: Before the year 2000, there was no dedicated childhood cancer service in Cameroon. The aim of this study was to investigate the progress made with pediatric oncology care in Cameroon from 2000 to 2020. METHOD: A literature search was conducted for published articles on childhood cancer in Cameroon and relevant documents, and conference abstracts were reviewed. The articles were analyzed under the themes: awareness, diagnosis, epidemiology, treatment, outcome, advocacy, partnerships, traditional and complementary medicine, palliative care, and capacity building. RESULTS: Low awareness on childhood cancer was addressed with education activities targeting the general population and health care professionals. Cancer diagnosis was achieved with cytology, histology, and simple imaging. Management for common and curable cancers was implemented with use of modified treatment regimens for low- and middle-income settings. Nutritional support was shown to mitigate the effects of malnutrition on treatment toxicity, and support was provided for transportation and accommodation. There was good collaboration between the pediatric oncology professionals nationally and twinning with international partners. Capacity building activities led to the availability of three pediatric oncologists and pediatric oncology-trained nurses. Advocacy nationally led to the support of the Ministry of Health with pediatric oncology-specific priority actions in the latest national cancer control plan. CONCLUSION: Childhood cancer should receive the necessary attention of health care policymakers in Cameroon. With continued commitment of government, nongovernmental organizations, charities, childhood cancer specialists, patient and parent groups, there should be an improved future for children with cancer in Cameroon.

RESUMO

BACKGROUND: Death during paediatric cancer treatment is common in sub-Saharan Africa. Using the infrastructure of Supportive Care for Children with Cancer in Africa (SUCCOUR), our objective was to describe fever and neutropenia (FN) characteristics and outcomes in order to identify potential areas for future intervention. METHODS: A multicentre prospective, observational cohort study was conducted in sub-Saharan Africa. Data were collected from September 2019 to March 2020. Children below 16 years with newly diagnosed cancer treated with curative intent were included. Data were abstracted in real time using standardised case report forms by trained personnel. Characteristics and outcomes of FN during the first 3 months of treatment were documented. RESULTS: A total of 252 patients were included (median age 6.0, range 0.2-15.0 years, 54% male). The most common cancer was Burkitt lymphoma (63/252, 25%). Among 104 FN episodes, 21 (21%) were associated with prolonged neutropenia (>1 week) and 32 (31%) were associated with profound neutropenia (absolute neutrophil count <0.1 × 109 /L). In 10/104 (10%) episodes, empiric antibiotics were started within 1 hour following fever onset and in 16/104 (15%) episodes, a blood culture was obtained before starting antibiotics. Malaria parasitaemia was detected in four of 104 (4%). A total of 11/104 (11%) patients died in the FN episodes. CONCLUSIONS: Although in most, FN was not associated with prolonged or profound neutropenia, 11% resulted in death. Areas to target include blood cultures prior to antibiotics and earlier initiation of empiric antibiotics. Future efforts should modify FN practices to reduce treatment-related mortality.

RESUMO

BACKGROUND: Deaths during paediatric cancer treatment are common in Africa. It is often difficult to distinguish between treatment-related and disease-related causes. To prevent these deaths, it is important to study them and identify the cause. The Supportive Care for Children with Cancer in Africa (SUCCOUR) programme enabled a study with the objective to identify the reasons for early death during treatment. METHODS: We conducted a multicentre prospective, observational cohort study in sub-Saharan Africa. Children younger than 16 years with newly diagnosed cancer treated with curative intent were included from 1 September 2019 until 30 March 2020. Data were abstracted in real time by trained personnel using standardised case report forms. The treating clinician's assessment of the cause of death and signs, symptoms and laboratory values of patients who died during the first 3 months of treatment (early death) were documented. RESULTS: We included 252 patients (median age 6.0, range 0.2-15.0 years, 54% male). The most common cancer was Burkitt lymphoma (63/252, 25%). Fifteen percent of patients (37/252) died during the first 3 months of treatment. Of these 37 patients, 33 (89%) died of a treatment-related cause. Treatment-related mortality of all patients in the first 3 months of treatment was 13% (33/252). CONCLUSION: Fifteen percent of patients had an early death during treatment and 13% had a treatment-related death. This suggests the need to improve supportive care. Implementation of supportive care pathways adapted to local circumstances may be helpful.

RESUMO

BACKGROUND: 'Treatmentabandonment' is a common and preventable cause of childhood cancer treatment failure in low- and middle-income countries (LMIC). Risk factors and effective interventions in LMIC are reported. Poverty and costs of treatment are perceived as overriding causes in sub-Saharan Africa. The objective of this study was to study potential determinants of treatment abandonment, including aspects of treatment costs in sub-Saharan Africa, to be better informed for planned future interventions. METHODS: A multicentre, prospective, observational, cohort study was conducted in five hospitals in sub-Saharan Africa. Children younger than 16 years with newly diagnosed cancer treated as inpatient with curative intent were included. The occurrence of treatment abandonment and potential determinants including aspects of treatment costs were documented during the first 3 months of treatment. RESULTS: We included 252 patients (median age 6.0, range 0.2-15.0 years, 54% male). The most common cancer was Burkitt lymphoma (63/252, 25%). Seven percent of patients (18 of 252) abandoned treatment. Two thirds (65%, 163/252) of patients had to borrow money to reach the hospital for the diagnosis and start of treatment. Treatment abandonment occurred more frequently in families who had to borrow money (16/163, 10%) versus those who did not (2/89, 2%; p = .026). CONCLUSIONS: Limiting costs for families and improved counselling may reduce treatment abandonment. Development and implementation of interventions to reduce treatment abandonment are required in sub-Saharan Africa.

RESUMO

Effective cancer registration is required for the development of cancer management policies, but is often deficient in the developing world. In 2008 cancer registration was set up Banso Baptist Hospital and Mbingo Baptist Hospital in the Northwest region of Cameroon, using the Pediatric Oncology Networked Database (POND). The objective of this study was to analyze the POND registry data for patients with cancer aged 0-15 years for the period 2004-15. A total of 1029 malignancies were recorded in children 0-15 years in the study period. The male-to-female ratio was 1.4:1. The median age at diagnosis was 7.22 years. The most common malignancies were lymphomas followed by nephroblastoma, retinoblastoma, rhabdomyosarcoma and Kaposi sarcoma. There were more Burkitt lymphomas cases between 2004 and 2009 than between 2010 and 2015, while the number of cases rose for other diagnoses like retinoblastoma and nephroblastoma. This report has demonstrated how pediatric oncology registration can be implemented, improved and sustained in a low- and middle-income country setting with limited resources. Using the data, these hospitals can improve their treatment planning and ensure the availability of essential chemotherapy for childhood cancers.

RESUMO

INTRODUCTION: The Collaborative Wilms Tumour (WT) Africa Project implemented an adapted WT treatment guideline in six centres in sub-Saharan Africa. The primary objectives were to describe abandonment of treatment, death during treatment, event-free survival (EFS) and relapse following implementation. An exploratory objective was to compare outcomes with the baseline evaluation, a historical cohort preceding implementation. METHODS: The Collaborative WT Africa Project is a multi-centre prospective clinical trial that began in 2014. Funding was distributed to all participating centres and used to cover treatment, travel and other associated costs for patients. Patient characteristics, tumour characteristics and events were described. RESULTS: In total, 201 WT patients were included. Two-year EFS was 49.9 ± 3.8% when abandonment of treatment was considered an event. Relapse of disease occurred in 21% (42 of 201) of all included patients and in 26% (42 of 161) of those who had a nephrectomy. Programme implementation was associated with significantly higher survival without evidence of disease at the end of treatment (52% vs 68.5%, P = .002), significantly reduced abandonment of treatment (23% vs 12%, P = .009) and fewer deaths during treatment (21% vs 13%, P = .06). CONCLUSION: This collaborative implementation of an adapted WT treatment guideline, using relatively simple and low-cost interventions, was feasible. Two-year EFS was almost 50%. In addition, a significant decrease in treatment abandonment and an increase in survival at the end of treatment were observed compared to a pre-implementation cohort. Future work should focus on decreasing deaths during treatment and will include enhancing supportive care.

RESUMO

BACKGROUND: Burkitt lymphoma (BL) is a curable childhood cancer. Treatment adherence is crucial for a good outcome, but is potentially problematic in low- and middle-income countries owing to parental financial constraints. AIMS: To investigate the association of destitution with treatment adherence and its effect on the survival of patients with BL. METHODS: Patients received free medical treatment from a twinning programme at two Cameroon Baptist hospitals. A destitution assessment questionnaire, based on socioeconomic status, was completed at diagnosis. Medical records were reviewed for treatment adherence and survival. Chi-squared and Fisher's exact tests were used to compare groups. Kaplan-Meier plots were used to calculate overall survival, and log-rank chi-squared tests when comparing survival rates between patient subgroups. Significance was measured at P < .05. RESULTS: The 225 children with BL had a mean age of 8.2 years (median 8.0) and the overall survival was 52%. The mean family destitution score was 56% on a linear scale. Few (8%) patients delayed treatment appointments. A quarter (25%) experienced more than a 1-week follow-up delay and 9.8% absconded within 1 year. The destitution score was not significantly associated with delay of treatment, but with delay in follow-up (P < .001). Guardian relationship (single mother) and patient's age were significantly associated with overall survival (P = .025). CONCLUSIONS: Though linked to poor follow-up, destitution was not significantly associated with absconding patients, poor outcome or poor adherence to treatment, probably due to comprehensive financial support from the international twinning programme. However, additional support for single mothers should be considered.

RESUMO

BACKGROUND: The Collaborative Wilms Tumour (WT) Africa Project has implemented an adapted WT treatment guideline in sub-Saharan Africa as a multi-centre prospective clinical trial. A retrospective, baseline evaluation of end-of-treatment outcome was performed for a 2-year period prior to the introduction of this guideline. The collaborative project aims to reduce both treatment abandonment and death during treatment to less than 10% for improving survival. PROCEDURE: All participating centres obtained local Institutional Research Board (IRB) approval and implemented the adapted WT treatment guideline. End-of-treatment outcome was documented for 2 years. It was divided into alive without evidence of disease, treatment abandonment, death during treatment and persistent disease. The outcome of children enroled in the first 2 years of the prospective clinical trial has been compared to the outcome before the start of the project. RESULTS: One hundred twenty-two patients were included in the baseline evaluation (2011-2012) and 133 in the first 2 years of the collaborative clinical trial (2014-2015). The percentage of patients alive without evidence of disease at the end of treatment increased from 52% (63/122) to 68% (90/133; P = 0.01). Treatment abandonment decreased from 23% (28/122) to 13% (17/133; P = 0.03). Death during treatment decreased from 21% (26/122) to 13% (17/133; P = 0.07). CONCLUSION: This collaboration, using relatively simple and low-cost interventions, led to a significant decrease in treatment abandonment and increase in survival without evidence of disease at the end of treatment.

RESUMO

BACKGROUND: Cancer is a major cause of death in children worldwide, and the recorded incidence tends to increase with time. Internationally comparable data on childhood cancer incidence in the past two decades are scarce. This study aimed to provide internationally comparable local data on the incidence of childhood cancer to promote research of causes and implementation of childhood cancer control. METHODS: This population-based registry study, devised by the International Agency for Research on Cancer in collaboration with the International Association of Cancer Registries, collected data on all malignancies and non-malignant neoplasms of the CNS diagnosed before age 20 years in populations covered by high-quality cancer registries with complete data for 2001-10. Incidence rates per million person-years for the 0-14 years and 0-19 years age groups were age-adjusted using the world standard population to provide age-standardised incidence rates (WSRs), using the age-specific incidence rates (ASR) for individual age groups (0-4 years, 5-9 years, 10-14 years, and 15-19 years). All rates were reported for 19 geographical areas or ethnicities by sex, age group, and cancer type. The regional WSRs for children aged 0-14 years were compared with comparable data obtained in the 1980s. FINDINGS: Of 532 invited cancer registries, 153 registries from 62 countries, departments, and territories met quality standards, and contributed data for the entire decade of 2001-10. 385 509 incident cases in children aged 0-19 years occurring in 2·64 billion person-years were included. The overall WSR was 140·6 per million person-years in children aged 0-14 years (based on 284 649 cases), and the most common cancers were leukaemia (WSR 46·4), followed by CNS tumours (WSR 28·2), and lymphomas (WSR 15·2). In children aged 15-19 years (based on 100 860 cases), the ASR was 185·3 per million person-years, the most common being lymphomas (ASR 41·8) and the group of epithelial tumours and melanoma (ASR 39·5). Incidence varied considerably between and within the described regions, and by cancer type, sex, age, and racial and ethnic group. Since the 1980s, the global WSR of registered cancers in children aged 0-14 years has increased from 124·0 (95% CI 123·3-124·7) to 140·6 (140·1-141·1) per million person-years. INTERPRETATION: This unique global source of childhood cancer incidence will be used for aetiological research and to inform public health policy, potentially contributing towards attaining several targets of the Sustainable Development Goals. The observed geographical, racial and ethnic, age, sex, and temporal variations require constant monitoring and research. FUNDING: International Agency for Research on Cancer and the Union for International Cancer Control.

RESUMO

Dopaminergic neurotransmission in the striatum has been widely implicated in the reinforcing properties of substances of abuse. However, the striatum is functionally heterogeneous, and previous work has mostly focused on psychostimulant drugs. Therefore, we investigated how dopamine within striatal subregions modulates alcohol-directed behaviour in rats. We assessed the effects of infusion of the dopamine receptor antagonist alpha-flupenthixol into the shell and core of the nucleus accumbens (NAcc) and the dorsolateral striatum (DLS) on responding for alcohol under fixed ratio 1 (FR1) and progressive ratio (PR) schedules of reinforcement. Bilateral infusion of alpha-flupenthixol into the NAcc shell reduced responding for alcohol under both the FR1 (15 µg/side) and the PR schedule (3.75-15 µg/side) of reinforcement. Infusion of alpha-flupenthixol into the NAcc core (7.5-15 µg/side) also decreased responding for alcohol under both schedules. By contrast, alpha-flupenthixol infusion into the DLS did not affect FR1 responding, but reduced responding under the PR schedule (15 µg/side). The decreases in responding were related to earlier termination of responding during the session, whereas the onset and rate of responding remained largely unaffected. Together, these data suggest that dopamine in the NAcc shell is involved in the incentive motivation for alcohol, whereas DLS dopamine comes into play when obtaining alcohol requires high levels of effort. In contrast, NAcc core dopamine appears to play a more general role in alcohol reinforcement. In conclusion, dopaminergic neurotransmission acts in concert in subregions of the striatum to modulate different aspects of alcohol-directed behaviour.

RESUMO

BACKGROUND: Burkittlymphoma(BL) is the most common childhood cancer in Cameroon with a reported incidence of 3 per 100,000 children under 15 years in the Northwest region. Treatment at three Baptist mission hospitals has a recorded cure rate of over 50%. Traditional medicine(TM) is recognized by the national health system, but its scope is undefined and entraps children with BL. The aim of this study was to investigate the attitudes and practices of parents and traditional healers (TH) towards TM in children with BL in order to develop recommendations for an integrative approach and improved access to life-saving treatment for children with BL. METHODS: This is a descriptive case series of children diagnosed with BL treated at Banso, Mbingo, and Mutengene Baptist Hospitals between 2003 and 2014. A questionnaire was used to obtain the following information: demographic information, religion, the rate of use of TM, reasons why guardians chose to use TM, the diagnoses made by the TH, treatment offered, and the type of payment requested, based on the accounts of patient caregivers. Data was analyzed using Center for Disease Control Epi Info 7. RESULTS: Three hundred eighty-seven questionnaires were completed by parents/guardians. 55% had consulted a TH, of whom 76.1% consulted the TH as first choice. Common diagnoses provided by TH included liver problem, abscess, witchcraft, poison, hernia, side pain, mushroom in the belly and toothache. Methods of management included massage, cuts, concoctions, and incantations. The fee for these services included chickens, farm tools, and cash ranging from 200FCFA (0.4USD) to 100,000FCFA(200USD). The choice of TM was based on accessibility, failed clinic/hospital attendance, recommendation of relatives, and belief in TM. CONCLUSIONS: TH are involved in BL management in Cameroon. TH are ignorant about BL, resulting in non-referral, and thus delay in diagnosis and treatment. Collaboration with TH could reduce late diagnosis and improve cure rates of BL and other childhood cancers.

RESUMO

BACKGROUND: Alcohol is one of the most commonly used psychoactive substances. Prolonged alcohol use can result in alcohol use disorder (AUD), characterized by excessive and compulsive alcohol consumption. Importantly, however, the development of AUD only happens in a minority of individuals who consume alcohol. To understand the individual vulnerability for AUD, models that capture both the individual variability in alcohol consumption and the transition from casual to compulsive alcohol use are essential. METHODS: Individual variability in voluntary alcohol intake and the preference for alcohol were assessed under continuous alcohol access (CAA) and intermittent-every-other-day alcohol access (IAA) schedules in the home cage using outbred Lister Hooded rats. Subsequently, the reinforcing properties of alcohol were tested in an operant setting. In subsequent experiments, we performed a quinine adulteration experiment to assess inflexible alcohol consumption and blood alcohol levels (BALs) were assessed after voluntary alcohol consumption. RESULTS: We found marked individual differences in alcohol consumption and preference under both access schedules, whereby subgroups of high- and low-alcohol-drinking rats (HD and LD) could be identified. HD with IAA increased their alcohol intake over days in the first month, whereas LD did not. Moreover, when alcohol access time was extended from 7 to 24 h/d for rats with IAA, alcohol intake profoundly increased in HD with IAA, whereas LD with IAA maintained low levels of alcohol intake. Furthermore, HD earned more alcohol than LD under both fixed ratio and progressive ratio schedules of reinforcement. We further found that HD continued their intake of a quinine-adulterated alcohol solution to a larger extent than LD and HD showed higher BALs after 30 minutes of alcohol consumption. CONCLUSIONS: These profound individual differences in alcohol intake, reinforcement, motivation, and AUD-like behavior provide a promising tool to unravel the neurobehavioral underpinnings of individual vulnerability for AUD.

RESUMO

There is a considerable degree of individual vulnerability for alcohol use disorder (AUD) as only a subpopulation of individuals who regularly consume alcohol develop AUD. It is therefore very important to understand the factors and mechanisms that contribute towards the individual risk for AUD. In this respect, social influences, in particular during development, may be relevant for AUD as disruptions in early social experiences are associated with an increased risk for AUD. Social play, the most prominent form of social behaviour shown by young mammals, is rewarding and considered to be important for social, emotional and cognitive development. Recent studies suggest that early social isolation, effectively depriving animals from social play, increases the risk for addictive behaviour. The aim of this study was therefore to explore the long-term consequences of early social isolation on alcohol consumption and motivation for alcohol. To this end, rats were socially isolated from postnatal days 21-42, followed by 4 weeks of social housing, and voluntary alcohol consumption and operant responding for alcohol were determined in adulthood. We observed enhanced levels of alcohol consumption in adulthood in previously isolated rats, whereas operant responding for alcohol was not altered. The impact of early social isolation was independent of the individual variation in alcohol consumption. These data indicate that social isolation, during a developmental period when social play is highly abundant, enhances the propensity to consume alcohol in adulthood. This implies that early social experience may be a protective factor against excessive alcohol use.

RESUMO

BACKGROUND: Palliative care (PC) is the most appropriate treatment for patients with life-limiting, incurable diseases, but it is a relatively new concept in sub-Saharan Africa (SSA). A lack of curative treatment options for some conditions creates a great need for PC, but such services are rarely provided in SSA. More research into PC in SSA is urgently needed to create an evidence base to confirm the importance of appropriate PC services. OBJECTIVES: To gain a better understanding of the needs of patients and their families visited by a children's PC nurse in Cameroon and to identify aspects of the service that can be improved. METHODOLOGY: A qualitative study design with semi-structured interviews was used. Tape-recorded interviews were transcribed and thematically analysed. RESULTS: Twelve interviews were conducted with patients, carers and nurses. Financial aid, general disease improvement and prayers were the directly expressed needs of service recipients. Specialist training in children's PC was the main need expressed by the nurses. Open communication about clinical status and treatment failure, more detailed counselling, more distraction for patients and respite for carers were identified as underlying needs. CONCLUSION: It is possible to provide an effective children's PC service that meets the most urgent needs of recipients in a rural setting in SSA. Recommendations include improved counselling, specialist education for staff, expansion of local support networks and more frequent home visits. More studies are needed to help define the need for PC in children with life-limiting diseases.

RESUMO

Cancer is a leading cause of death and disability in sub-Saharan Africa and will eclipse infectious diseases within the next several decades if current trends continue. Hematologic malignancies, including non-Hodgkin lymphoma, leukemia, Hodgkin lymphoma, and multiple myeloma, account for nearly 10% of the overall cancer burden in the region, and the incidence of non-Hodgkin lymphoma and Hodgkin lymphoma is rapidly increasing as a result of HIV. Despite an increasing burden, mechanisms for diagnosing, treating, and palliating malignant hematologic disorders are inadequate. In this review, we describe the scope of the problem, including the impact of endemic infections, such as HIV, Epstein-Barr virus, malaria, and Kaposi sarcoma-associated herpesvirus. We additionally describe current limitations in hematopathology, chemotherapy, radiotherapy, hematopoietic stem cell transplantation, and supportive care and palliation. We review contemporary treatment and outcomes of hematologic malignancies in the region and outline a clinical service and research agenda, which builds on recent global health successes combating HIV and other infectious diseases. Achieving similar progress against hematologic cancers in sub-Saharan Africa will require the sustained collaboration and advocacy of the entire global cancer community.

RESUMO

The majority of children with cancer live in low- and middle-income countries (LMICs) with little or no access to cancer treatment. The purpose of the paper is to describe the current status of childhood cancer treatment in Africa, as documented in publications, dedicated websites and information collected through surveys. Successful twinning programmes, like those in Malawi and Cameroon, as well as the collaborative clinical trial approach of the Franco-African Childhood Cancer Group (GFAOP), provide good models for childhood cancer treatment. The overview will hopefully influence health-care policies to facilitate access to cancer care for all children in Africa.

RESUMO

INTRODUCTION: The role of age and sex in the presentation and outcome of endemic Burkitt lymphoma (BL) has not been studied recently. This study analysed these factors in 934 patients with BL who had received cyclophosphamide and intrathecal methotrexate as treatment. METHODS: Records of 934 children diagnosed with BL from 2004 to 2015 were obtained from our Paediatric Oncology Networked Database (POND) cancer registry. Age at diagnosis, sex, disease stage, time to diagnosis, delay in diagnosis, completion of treatment, rate of abandonment, and one-year survival rates were recorded and statistically analysed. RESULTS: The male to female ratio of 1.41 for the study population of 934. The median delay from onset of symptoms to diagnosis was 31 days. The St Jude stage distribution was I = 6.4%, II = 5.9%, III = 71.5% and IV = 16.2%. Significantly more patients presented with stage III disease in age groups 5-9 and 10-14 years than 0-4 years. The overall 1-year survival rate was 53.45%, respectively 77.1% for stage I, 67.9% for stage II, 55.1% for stage III and 32.4% for stage IV disease (p<0.001). There was no significant difference in survival by sex and age group. CONCLUSION: Patients aged under 5 years presented with less-advanced disease, but survival was not affected by age. Sex did not influence delay to diagnosis and overall survival. The long delay between the onset of symptoms and diagnosis emphasises the need for interventions to achieve an earlier diagnosis and a better survival rate.

RESUMO

These supportive care recommendations were prepared to guide doctors who practice in areas with significantly limited resources but who have sufficient infrastructure and training to treat children with cancer with curative intent. The success of any cancer treatment regimen depends largely on the availability and quality of supportive care and this also determines the intensity of treatment that can be delivered. We present practical recommendations on how to prevent infections, general nursing care, management of febrile neutropenia, nutritional assessment and support, treatment of co-infections and the social support to help prevent failure to complete treatment in resource poor settings.
