Surgical aspects and outcomes after nephrectomy for Wilms tumour in sub-Saharan Africa: A report from Wilms Africa Phase II-CANCaRe Africa.

BACKGROUND: Wilms tumour (WT) is one of the common and curable cancer types targeted by the Global Initiative for Childhood Cancer. Tumour excision is essential for cure. This analysis focuses on surgical outcomes of patients with WT in sub-Saharan Africa. METHODS: We implemented a risk-stratified WT treatment guideline as a multicentre, prospective study across eight hospitals and six countries. Eligibility criteria were age 6 months to 16 years, unilateral WT, surgery performed after preoperative chemotherapy and diagnosed between 1 January 2021 and 31 December 2022. Data collection included a specific surgical case report form (CRF). RESULTS: The study registered 230 patients, among whom 164 (71.3%) had a nephrectomy. Ninety-eight percent of patients had a completed surgical CRF. Out 164 patients, 50 (30.5%) had distant metastases. Median tumour diameter at surgery was 11.0 cm. Lymph node sampling was done in 122 (74.3%) patients, 34 (20.7%) had intraoperative tumour rupture, and for 18 (10.9%), tumour resection involved en bloc resection of another organ. Tumour size at surgery was significantly correlated with tumour rupture (p < .01). With a median follow-up of 17 months (range: 2-33), 23 (14.0%) patients have relapsed. Twenty-two (13.4%) patients abandoned treatment post nephrectomy. Two-year event-free survival was 60.4% ± 4.7% with treatment abandonment as an event. CONCLUSION: Survival post nephrectomy is challenged by treatment abandonment, treatment-related mortality and relapse. Large tumours after preoperative chemotherapy were associated with a higher risk of tumour rupture. Earlier diagnosis and access to radiotherapy are expected to improve survival.

Prevention of treatment abandonment remains an important challenge to increase survival of Wilms tumor in sub-Saharan Africa: A report from Wilms Africa-CANCaRe Africa.

BACKGROUND: The Wilms Africa studies implemented an adapted Wilm's tumor (WT) treatment protocol in sub-Saharan Africa in two phases. Phase I began with four sites and provided out-of-pocket costs. Phase II expanded the number of sites, but lost funding provision. Objective is to describe the outcomes of Phase II and compare with Phase I. METHODS: Wilms Africa Phase I (n = 4 sites; 2014-2018) and Phase II (n = 8 sites; 2021-2022) used adapted treatment protocols. Funding for families' out-of-pocket costs was provided during Phase I but not Phase II. Eligibility criteria were age less than 16 years and newly diagnosed unilateral WT. We documented patients' outcome at the end of planned first-line treatment categorized as treatment abandonment, death during treatment, and disease-related events (death before treatment, persistent disease, relapse, or progressive disease). Sensitivity analysis compared outcomes in the same four sites. RESULTS: We included 431 patients in Phase I (n = 201) and Phase II (n = 230). The proportion alive without evidence of disease decreased from 69% in Phase I to 54% in Phase II at all sites (p = .002) and 58% at the original four sites (p = .04). Treatment abandonment increased overall from 12% to 26% (p < .001), and was 20% (p = .04) at the original four sites. Disease-related events (5% vs. 6% vs. 6%) and deaths during treatment (14% vs. 14% vs. 17%) were similar. CONCLUSION: Provision of out-of-pocket costs was important to improve patient outcomes at the end of planned first-line treatment in WT. Prevention of treatment abandonment remains an important challenge.

Evaluating the baseline survival outcomes of the "six Global Initiative for Childhood Cancer index cancers" in Africa.

Limited survival data for the six Global Initiative for Childhood Cancer (GICC) priority cancers are available in Africa. Management of pediatric malignancies in Africa is challenging due to lack of resources, setting-specific comorbidities, high rates of late presentation and treatment abandonment. Reporting of outcome data is problematic due to the lack of registries. With the aim of evaluating the feasibility of baseline outcomes for the six index cancers, we present a descriptive analysis of respective survival rates in Africa. The survival rates were between 18% (lower middle-income countries) to 82.3% (upper middle-income countries) for acute lymphoblastic leukemia, between 26.9% (low-income countries) to 77.9% (upper middle-income countries) for nephroblastoma, between 23% (low-income countries) to 100% (upper middle-income countries), for retinoblastoma, 45% (low-income countries) to 95% (upper middle-income countries) for Hodgkin lymphoma and 28% (low-income countries) to 76% (upper middle-income countries) for Burkitt lymphoma. Solutions to improve survival rates and reported outcomes include establishing and funding sustainable registries, training and to actively include all countries in consortia from different African regions.HighlightsContinental differences in childhood cancer management such lack of resources, setting-specific comorbidities, high rates of late presentation and treatment abandonment, present challenges to the achievement of Global Initiative for Childhood Cancer goals.The available data registries do not adequately inform on the true incidences and outcomes of childhood cancers in Africa.The pathophysiology of some childhood cancers in Africa are associated with high-risk prognostic factors.Outcomes can be improved by greater regional collaboration to manage childhood cancer based on local resources and tumor characteristics.Some individual countries have reached the Global Initiative for Childhood Cancer goals for single cancers and it should be possible for more African countries to follow suit.

Outcome of retinoblastoma treatment protocol in Cameroon as per SIOP-PODC recommendation for a low-income setting.

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.

Two decades of childhood cancer care in Cameroon: 2000-2020.

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.

Fever and neutropenia outcomes and areas for intervention: A report from SUCCOUR - Supportive Care for Children with Cancer in Africa.

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.

Early death and treatment-related mortality: A report from SUCCOUR - Supportive Care for Children with Cancer in Africa.

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.

The Evolution of a Hospital-Based Cancer Registry in Northwest Cameroon from 2004 to 2015.

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.

Improvement of overall survival in the Collaborative Wilms Tumour Africa Project.

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.

Destitution, treatment adherence and survival of children with Burkitt lymphoma in a twinning programme in Northwest Cameroon.

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.

Improved outcome at end of treatment in the collaborative Wilms tumour Africa project.

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.

Factors associated with inconsistent condom use in adolescents with negative or unknown HIV status in Northwest Cameroon.

The purpose of this study is to evaluate the association between utilization of HIV testing and condom use amongst Cameroonian youths/adolescents who are not known to be HIV-infected. Worldwide, HIV is spreading most quickly amongst youths/adolescents. Between 44% and 82% of sexually active youths in Cameroon report inconsistent condom use. Data regarding utilization of HIV testing and condom use are lacking. A cross-sectional survey was administered to 431 youths ages 12-26 years in Cameroon from September 2011 to December 2011. Data on sociodemographics, sexual risk behaviors, self-reported HIV status, and condom use were collected. We compared rates of inconsistent condom use between those with known HIV negative status who utilized testing (HIV-N) and those with unknown status due to unutilized testing (HIV-U). Inconsistent condom use was defined as responding "never," "sometimes," or "usually," while consistent condom use was defined as responding "always" to questions regarding frequency of condom use. Generalized estimating equations were applied to assess the association between HIV testing and inconsistent condom use, adjusting for other confounders. Of 414 eligible respondents, 205 were HIV-U and 209 were HIV-N. HIV-U subjects were younger (mean age = 16.4 vs. 17.9, p < 0.001) and more likely to report living in an urban area (p = 0.002) than HIV-N subjects. Seventy-two percent (137/191) of sexually active youths reported inconsistent condom use. After adjusting for potential confounders, HIV-U status (odds ratio [OR] = 3.97, 95% confidence interval [CI] = 1.68-6.01) was associated with inconsistent condom use. Similarly, female gender (OR = 3.2, 95% CI = 1.29-7.89) was associated with inconsistent condom use, while older age at sexual debut was associated with a decreased risk for inconsistent condom use (OR = 0.67, 95% CI = 0.56-0.81). Cameroonian adolescents report high rates of inconsistent condom use which we found to be associated with self-reported unknown HIV status due to unutilized HIV testing. Successful HIV prevention programs among African youths/adolescents may benefit from expanded HIV testing programs.

Burkitt lymphoma: The effect of age, sex and delay to diagnosis on treatment completion and outcome of treatment in 934 Patients in Cameroon.

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.

Assessment of barriers to optimal cancer control in adult cancer treatment centres in Cameroon.

Approximately 20,745 new cases of cancer were registered annually with 13,199 (64%) deaths in 2020 in Cameroon. Despite the increasing cancer burden, there is a paucity of reliable data that can enhance decision-making for cancer control in Cameroon. This assessment was, therefore, designed to generate data that may enable stakeholders, policymakers and funders to make data-driven decisions on cancer control. We conducted a cross-sectional survey in July 2020, which enabled us to collect data on key cancer variables from six adult cancer treatment centres in Cameroon. The key components of the assessment included case detection, service availability, human resource capacity, cost of chemotherapy and radiotherapy, the safety of chemotherapy sessions, data systems, patient education, palliative care, funding for chemotherapy and chemotherapy stock. Data were compiled and analysed using Microsoft Excel 2016. Data from four of the 6 sites show that 1,636 new cases were recorded representing an annual case detection rate of 11.8%. All the six assessed facilities offered chemotherapy services, 5/6 (83.3%) offered surgery for cancers, while just 1 (16.7%) offered radiotherapy services. In addition, none offered nuclear medicine services for cancer care and treatment. Similarly, none of the facilities had the WHO-recommended number of human resources for optimal cancer care. Overall, there were only 6 medical oncologists, 2 surgical oncologists, 3 radiation oncologists and 14 oncology nurses providing services across the 6 cancer treatment centres. Treatment services are expensive for an average national, with a complete course of chemotherapy followed by radiotherapy costing ~XAF 1,240,000 (~$2,480). None of the survey facilities had a recommended safe biosafety cabinet and clean room for the preparation of chemotherapies, rendering the preparation of chemotherapies suboptimal and hazardous. Data collection tools were manual, relatively available and very different across all the surveyed sites and the interval for data collection and transmission was collectively undefined. Optimal cancer care in adult cancer treatment centres is limited by several health systems and socio-economic factors. The identification of these barriers has enabled the formulation of action-oriented interventions, leveraging on the recently adopted national strategy for the prevention and control of cancers in the country.

Cancer and COVID-19 Experiences at African Cancer Centers: The Silver Lining.

PURPOSE: The COVID-19 pandemic significantly disrupted cancer care in Africa, further exposing major health disparities. This paper compares and contrasts the experiences of 15 clinicians in six different African cancer centers to highlight the positive aspects (silver linings) in an otherwise negative situation. METHODS: Data are from personal experience of the clinicians working at the six cancer centers blended with what is available in the literature. RESULTS: The impact of COVID-19 on cancer care appeared to vary not only across the continent but also over cancer centers. Different factors such as clinic location, services offered, available resources, and level of restrictions imposed because of COVID-19 were associated with these variations. Collectively, delays in treatment and limited access to cancer care were commonly reported in the different regions. CONCLUSION: There is a lack of data on cancer patients with COVID-19 and online COVID-19 and cancer registries for Africa. Analysis of the available data, however, suggests a higher mortality rate for cancer patients with COVID-19 compared with those without cancer. Positive or silver linings coming out of the pandemic include the adoption of hypofractionated radiation therapy and teleoncology to enhance access to care while protecting patients and staff members. Increasing collaborations using online technology with oncology health professionals across the world are also being seen as a silver lining, with valuable sharing of experiences and expertise to improve care, enhance learning, and reduce disparities. Advanced information and communication technologies are seen as vital for such collaborations and could avail efforts in dealing with the ongoing pandemic and potential future crises.

Burkitt lymphoma: residual abdominal tumor volume after induction therapy correlates with outcome.

Staging investigations in the Malawi 2003 BL protocol included abdominal ultrasonography. This sometimes demonstrated tumor that was not palpable. Patients with no palpable tumor following induction with three courses of cyclophosphamide were considered to be in remission, although residual intraabdominal tumor was documented in some by chance. We repeated ultrasonography on day 29 on 22 new patients with non-palpable abdominal BL following induction. The relapse rate after 1 year correlated with the largest residual tumor volume, and was 17% for tumors 0-35 ml, and 75% for tumors > or = 35 ml in volume. Risk patients were thus identified.

The outcome and cost of a capacity-building training programme on the early recognition and referral of childhood cancer for healthcare workers in North-West Cameroon.

Aim: Early cancer diagnosis is necessary to improve survival rates. The aim of this study was to assess the outcome and cost of the childhood cancer training programme amongst healthcare workers. Design: This was a prospective pre-post study design, using questionnaires for pre- and post-training testing. The warning signs of childhood cancer were used as the main teaching content to improve recognition and early diagnosis. Methods: Pre-training and post-training knowledge, as well as attitude questionnaires, was administered at the beginning and at the end of each training workshop. Paired samples t test and chi-square were used to compare the change in knowledge and differences between groups. Results: The overall percentage knowledge score increased from 51%-85% (p < .001). The doctors had a better knowledge score than the nurses in the pre-test (70% versus 50%, p = .008), but there was no significant difference in the post-test scores. The cost of training was €25.06 per healthcare worker. Conclusion: We recommend similar training programmes in public health to improve early diagnosis of childhood cancer.

Retrospective analysis of the prevalence of and factors associated with condom use among young HIV-infected women in Cameroon.

OBJECTIVES: Young women are more likely to be infected with HIV globally, in sub-Saharan Africa, and in Cameroon. Despite its clear clinical and public health benefits, condom use among HIV-infected women continues to be low. The objective of this study was to describe the prevalence of inconsistent condom use among HIV-infected women in Cameroon and the factors associated with it. METHODS: We conducted a cross-sectional study of HIV-infected young women aged 17-26 years from three semi-urban HIV clinics in the Northwest Region of Cameroon. This study was a subgroup analysis of a previously reported study on inconsistent condom use in HIV-infected and -uninfected youth. Inconsistent condom use was defined as reporting "sometimes" or "never" to questions regarding frequency of condom use. Logistic regression modeling was used to determine factors associated with inconsistent condom use. RESULTS: A total of 84 participants were recruited and submitted completed questionnaires for analysis. Median age was 24 years (interquartile range = 22-25) and the median age at HIV diagnosis was 21 years (interquartile range = 20-23). Fifty percent of the participants reported no prior schooling or only primary school education. Overall, 61/84 (73%) reported inconsistent condom use. After adjusting for potential confounders, education to the secondary school level was protective against inconsistent condom use (odds ratio = 0.19; confidence interval: 0.04-0.95), and having ≥2 pregnancies was associated with inconsistent condom use (odds ratio = 7.52; confidence interval: 1.67-34.00). CONCLUSION: There is a high prevalence of inconsistent condom use among young HIV-infected women in Cameroon, which appears to be associated with lower levels of educational attainment and higher parity. Further larger studies assessing the factors associated with poor condom use in this population are warranted and may inform public health policy in resource-limited settings with high HIV prevalence.

The Collaborative Wilms Tumour Africa Project; baseline evaluation of Wilms tumour treatment and outcome in eight institutes in sub-Saharan Africa.

AIM: Reported survival of Wilms tumour in sub-Saharan Africa is below 50%. A published International Society of Pediatric Oncology (SIOP) Pediatric Oncology in Developing Countries (PODC) consensus adapted treatment guideline is implemented as a multi-centre prospective clinical trial at eight centres in sub-Saharan Africa. A baseline evaluation has been done to help decide on priorities to improve outcome and to assess improvements over time. METHODS: A retrospective chart review was performed of patients admitted with Wilms tumour in the three years (2011-2013) preceding the collaborative trial. Patient outcome at the end of treatment was documented for all patients diagnosed in 2011 and 2012. Outcome was classified as (1) alive, no evidence of disease; (2) alive with disease; (3) died during treatment and (4) incomplete treatment. Details on treatment facilities, staff and estimated cost of treatment are documented. RESULTS: Every year 114-130 patients are diagnosed. The mean survival at end of treatment is 39% (69/176) ranging from 11% to 61%. Incomplete treatment is the most common cause of treatment failure with 31% (54/176), ranging from 14% to 48% between centres. Twenty-six percent (46/176) of patients died during treatment, ranging from 13% to 37%. Estimated cost of treatment for parents ranged from 100 US$ to 1100 US$ and was considered an important cause of failure to complete treatment. CONCLUSION: Overall two year survival is estimated at 25%. Prevention of incomplete treatment is possible and will positively affect outcome. Sharing similar local challenges in this regional collaborative project helps to identify and implement feasible, sustainable and successful strategies.
