Cost and cost-effectiveness of childhood cancer treatment in low-income and middle-income countries: a systematic review

Organization of shared care networks and their role in overcoming challenges and enhancing outcomes for childhood cancer: A systematic review

This systematic review examines shared care networks (SCNs) in pediatric oncology as a strategic response to the healthcare challenges in low- and middle-income countries. SCNs integrate specialized hubs with local satellite centers to enhance accessibility and quality of care. Our methodology included a search of PubMed, Embase, Google Scholar, and Scopus, selecting peer-reviewed articles from the last 20 years. We analyzed nine studies, focusing on SCN definitions, models, and outcomes. Findings reveal that SCNs improve clinical outcomes and patient satisfaction, while reducing economic and emotional burdens through standardized protocols and efficient referral systems. Despite the benefits, challenges remain in maintaining consistent care quality and communication across centers. The review underscores the need for further research to quantify benefits, examine long-term outcomes, and refine operational practices to optimize SCNs' effectiveness in pediatric oncology.

Unraveling Copy Number Alterations in Pediatric B-Cell Acute Lymphoblastic Leukemia: Correlation with Induction Phase Remission Using MLPA

OBJECTIVE

Acute Lymphoblastic Leukemia (ALL) is the most common malignancy occurring in children. Copy number alterations (CNA) like PAX5, CDKN2A/2B, PAR1 Region, ETV6, IKZF1, BTG1, and RB1 gene deletion are important genetic events that define and prognosticate B-cell ALL. Thus, this study aimed to evaluate associations of CNA with induction phase remission status in childhood B-cell ALL.

METHODS

This study was observational with a cross-sectional design at the Dharmais Cancer Hospital, Harapan Kita Mother and Children Hospital, and Tangerang Regional Public Hospital. We evaluated 74 pediatric B-cell ALL cases with 1-18-year-olds. Genomic DNA was analyzed by Multiplex Ligation Dependent Probe Amplification Assay (MLPA). This study used the P335 ALL-IKZF1 panel kit, which contains several ALL-related genes. The patient's clinical and laboratory characteristics were collected from medical records from January to December 2019.

RESULT

We observed gene copy number alteration in children with B-Cell ALL. PAX5 was the most commonly observed gene deletion, followed by CDKN21/2B, ETV6, IKZF1, BTG1, RB1, and PAR1 Region. Based on gene mutations, only the PAX5 had a significant association with the remission status of pediatric B-cell ALL (p-value <0.05; OR = 3.91). It showed that patients with PAX5 gene mutations have 3.9 times the risk of no remission and/or relapse compared to those without PAX5 gene mutations.

CONCLUSION

Patients with mutations in the PAX5 gene have a higher chance of not achieving remission and/or experiencing relapse than those without such mutations. The MLPA method can be utilized for examining copy number alterations, which is valuable for achieving more precise stratification in diagnosis.. Further research is needed to expand upon this finding.

Determining the cost and cost-effectiveness of childhood cancer treatment in Haiti

Haiti is a low-income country with one of the lowest human development index rankings in the world. Its childhood cancer services are provided by a single hospital with the only dedicated paediatric oncology department in the country. Our objective was to assess the cost and cost-effectiveness of all types of childhood cancer in Haiti to help prioritise investments and to support national cancer control planning. All costing data were collected from the year 2017 or 2018 hospital records. Costs were classified into 11 cost categories, and the proportion of the overall budget represented by each was calculated and converted from Haitian Gourde to United States dollars. The 5-year survival rate was retrieved from hospital records and used to calculate the cost-effectiveness of disability-adjusted life year (DALY) averted, using a healthcare costing perspective. Additional sensitivity analyses were conducted accounting for late-effect morbidity and early mortality and discounting rates of 0%, 3% and 6%. The annual cost of operating a paediatric oncology unit in Haiti treating 74 patients with newly diagnosed cancer was $803,184 overall or $10,854 per patient. The largest cost category was pharmacy, constituting 25% of the overall budget, followed by medical personnel (20%) and administration (12%). The cost per DALY averted in the base-case scenario was $1,128, which is 76% of the gross domestic product per capita, demonstrating that treating children with cancer in Haiti is very cost-effective according to the World Health Organisation Choosing Interventions that are Cost-Effective (WHO-CHOICE) threshold. In the most conservative scenario, the cost per DALY averted was cost-effective by WHO-CHOICE criteria. Our data will add to the growing body of literature illustrating a positive return on investment associated with diagnosing and treating children with cancer in even the most resource-limited environments. We anticipate that these data will aid local stakeholders and policymakers when identifying cancer control priorities and making budgetary decisions.

The Landscape of Pediatric Radiation Oncology in Nigeria

Radiation therapy (RT) is an essential part of the multidisciplinary treatment of pediatric cancer. Over the past five decades, significant advances have been made in the delivery of RT, with better dose delivery to disease targets while minimizing exposure to nearby organs at risk. These advances have led to improved treatment outcomes, increased survival, and reduced treatment-related toxicities. Advanced treatment techniques, however, require significant investment in infrastructural and personnel resources. This review documents what is currently available regarding expertise and infrastructure for pediatric radiation oncology practice in Nigeria. It was performed to serve as a foundation for the creation and design of tailored solutions (initiatives and policies) to increase pediatric radiation availability, accessibility, and equity in Nigeria and ultimately improve pediatric cancer treatment outcomes in the region.

Developing and sustaining high-quality care for children with cancer: the WHO Global Initiative for Childhood Cancer

Cancer is a major public health concern, impacting nearly 20 million people each year, and it is responsible for 1 in 6 deaths worldwide. The burden of cancer is increasing rapidly, straining health systems that are unable to prevent and manage the disease. Childhood cancer constitutes a significant and relevant public health challenge; it was the ninth leading cause of childhood disease globally, according to findings by the Global Burden of Disease 2017 study. Almost 80% of all children diagnosed with cancer live in low- and middle-income countries where treatment is often unavailable or unaffordable. As a result, only about 15-45% of these children survive compared with more than 80% in high-income countries. This represents a great health inequity. Delivering on the mandate provided by World Health Assembly resolution 70.12, WHO together with St. Jude Children's Research Hospital and other global partners launched the Global Initiative for Childhood Cancer at the United Nations General Assembly during the third High-level Meeting on the prevention and control of noncommunicable diseases in September 2018. The Initiative aims to increase global survival for children with cancer to at least 60% by 2030, while reducing suffering for all children with cancer. Five years after launching the Initiative, more than 70 countries across the World Health Organization's 6 regions have advanced to different phases of action through implementation of the Initiative's CureAll framework for action. Many successful approaches to implementing the CureAll pillars and enablers have demonstrated that improving care for children with cancer in low- and middle-income countries is possible as long as there is strong political will, multisectoral commitments and strategic investment.

Financial costs of pediatric cancer management in Africa: systematic review

The high costs of cancer treatment and the lack of investment in health care are significant barriers to public health on the African continent. The objective of this study was to investigate the financial cost of children cancer treating in sub-Saharan Africa. We systematically searched PubMed, Cochrane, and Google Scholar to identify relevant studies between March 2000 and December 2022. We selected articles that specifically addressed the US dollar financial costs of childhood cancer in African countries. Medians and interquartile ranges (IQR) were calculated. We also calculated the economic burden of childhood cancer at the individual level, by dividing the direct costs of cancer per patient by the GDP per capita, PPP of the country studied. The quality of economic studies was assessed using the CHEERS (2022) 28-point checklist. A total of 17 studies met our eligibility criteria. The median (IQR) of total childhood cancer costs by region was $909.5 ($455.3-$1,765) and ranged from $88803.10 for neuroblastoma to $163.80 for lymphoma. No significant differences (p < 0.05) were observed for comparisons of the direct cost of childhood cancer between the geopolitical zone of sub-Saharan Africa. Differences in the direct costs of childhood cancer were significant for different cancer types (p < 0.05). In the majority of 17 out of 54 countries on Africa the continent, the economic burden of childhood cancer exceeds 80% of GDP per capita, PPP, up to 345.38% of Nigeria's GDP for Rhabdomyosarcoma. The cost of treating childhood cancers is high in Africa is catastrophic, if not downright prohibitive for households in Sub-Saharan Africa. We believe that the data from our study will be able to help make different objective advocacy allowing it to be provided with funds based of the evidence that can strengthen this program in order to install cancerology structures in the countries and by following the system plan. Cost reduction in the treatment of childhood cancer in particular and in general all types of cancer.

Approval of the study was given by the ethics committee of the Faculty of Medicine of the University of Lubumbashi (UNILU/CEM/135/2018) and (UNILU/CEM/096/2019).

Influence of health-insurance on treatment outcome of childhood cancer in Western Kenya

BACKGROUND

Few governments in low and middle-income countries (LMIC) have responded favourably to the international plea for Universal Health Coverage. Childhood cancer survival in LMIC is often below 20%. Limited health-insurance coverage may contribute to this poor survival. Our study explores the influence of health-insurance status on childhood cancer treatment outcomes in a Kenyan academic hospital.

METHODS

This was a retrospective medical records review of all children diagnosed with cancer at Moi Teaching and Referral Hospital between 2010 and 2016. Socio-demographic and clinical data was collected using a structured data collection form. Fisher's exact test, chi-squared test, Kaplan-Meier method, log-rank test and Cox proportional hazard model were used to evaluate relationships between treatment outcomes and patient characteristics. Study was approved by Institutional Research Ethics Committee.

FINDINGS

From 2010-2016, 879 children were newly diagnosed with cancer. Among 763 patients whose records were available, 28% abandoned treatment, 23% died and 17% had progressive/relapsed disease resulting in 32% event-free survival. In total 280 patients (37%) had health-insurance at diagnosis. After active enrolment during treatment, total health-insurance registration level reached 579 patients (76%). Treatment outcomes differed by health-insurance status (P < 0.001). The most likely treatment outcome in uninsured patients was death (49%), whereas in those with health-insurance at diagnosis and those who enrolled during treatment it was event-free survival (36% and 41% respectively). Overall survival (P < 0.001) and event-free survival (P < 0.001) were higher for insured versus uninsured patients. The hazard-ratio for treatment failure was 0.30 (95% CI:0.22-0.39; P < 0.001) for patients insured at diagnosis and 0.32 (95% CI:0.24-0.41; P < 0.001) for patients insured during treatment in relation to those without insurance.

INTERPRETATION

Our study highlights the need for Universal Health Coverage in LMIC. Children without health-insurance had significantly lower survival. Childhood cancer treatment outcomes can be ameliorated by strategies that improve health-insurance access.

Cost and Cost-Effectiveness of Treating Childhood Cancer at Jimma Medical Center

Background

More than 70% of childhood cancer patients die in Sub-Saharan African countries due to a lack of access. Additionally establishing a childhood cancer treatment service is perceived as expensive by the decision-makers of LMICs. However, there is a paucity of evidence on the actual cost and cost-effectiveness of this service in LMICs including Ethiopia. This study provides context-relevant evidence to consider childhood cancer treatment in the healthcare priority settings in Ethiopia and other LMICs.

Methods

Newly admitted case files of children for the year 2020/21 were reviewed. The cost was analyzed from the provider's perspective. The effectiveness was calculated using DALY averted based on the 5 years of survival rates, which is estimated from the 1-year survival rate of Kaplan-Meier output. The do-nothing was our comparator, and we assumed no cost (zero cost) will be incurred for the comparator. To account for sensitivity analyses, we varied the discount rate, 5-year survival rate, and life expectancy.

Results

During the study period, 101 children were treated in the unit. The total annual and unit cost to give treatment to childhood cancer patients was estimated at $279,648 and $2769, respectively. The highest per-patient annual unit cost of treatment was Hodgkin's lymphoma ($6252), while Retinoblastoma ($1520) was the least. The cost per DALY averted was $193, which is significantly less than Ethiopia's GDP per capita ($936.3). The results remained very cost-effective in sensitivity analyses.

Conclusion

Childhood cancer treatment is very cost-effective in Ethiopia as per WHO-CHOICE thresholds even in a conservative adjustment of assumptions. Therefore, to enhance and improve children's health, childhood cancer should get a better concern in health priority.

Cost of childhood cancer treatment in Ethiopia

BACKGROUND

Despite the recent interest in expanding pediatric oncology units in Ethiopia, reflected in the National Childhood and Adolescent Cancer Control Plan (NCACCP), little is known about the cost of running a pediatric oncology unit and treating childhood cancers.

METHODS

We collected historical cost data and quantity of services provided for the pediatric oncology unit and all other departments in Tikur Anbessa Specialized Hospital (TASH) from 8 July 2018 to 7 July 2019, using a provider perspective and mixed (top-down and bottom-up) costing approaches. Direct costs (human resources, drugs, supplies, medical equipment) of the pediatric oncology unit, costs at other relevant clinical departments, and overhead cost share are summed up to estimate the total annual cost of running the unit. Further, unit costs were estimated at specific childhood cancer levels.

RESULTS

The estimated annual total cost of running a pediatric oncology unit was USD 776,060 (equivalent to USD 577 per treated child). The cost of running a pediatric oncology unit per treated child ranged from USD 469 to USD 1,085, on the scenario-based sensitivity analysis. Drugs and supplies, and human resources accounted for 33% and 27% of the total cost, respectively. Outpatient department and inpatient department shared 37% and 63% of the cost, respectively. For the pediatric oncology unit, the cost per OPD visit, cost per bed day, and cost per episode of hospital admission were USD 36.9, 39.9, and 373.3, respectively. The annual cost per treated child ranged from USD 322 to USD 1,313 for the specific childhood cancers.

CONCLUSION

Running a pediatric oncology unit in Ethiopia is likely to be affordable. Further analysis of cost effectiveness, equity, and financial risk protection impacts of investing in childhood cancer programs could better inform the prioritization of childhood cancer control interventions in the Ethiopia Essential Health Service Package.

Current status of African pediatric oncology education efforts aligned with the Global Initiative for Childhood Cancer

Education of the pediatric oncology workforce is an important pillar of the World Health Organization CureAll technical package. This is not only limited to healthcare workers, but all stakeholders in the childhood cancer management process. It includes governmental structures, academic institutions, parents and communities. This review evaluated the current educational and advocacy training resources available to the childhood cancer community, the contribution of SIOP Africa in the continental educational needs and evaluated future needs to improve the management of pediatric malignancies in reaching the Global Initiative for Childhood Cancer goals. Childhood cancer, unlike adult cancers, has not been prioritized in African cancer control plans nor the teaching and advocacy surrounding pediatric oncology. The availability of formal training programs for pediatric oncologists, pediatric surgeons and radiotherapy specialists are limited to particular countries. In pharmacy and nutritional services, the exposure to pediatric oncology is limited while training in advocacy doesn't exist. Many nonacademic stakeholders are creating the opportunities in Africa to gain experience and train in these various fields, but formal training programs should still be advocated for. LEARNING POINTSThe African continent has various resources to increase the capacity of childhood cancer care stakeholders to increase their knowledge.African pediatric oncology teams rely on a multitude of international sources for training while developing their own.There is a greater need for formal, standardized cancer training especially for pediatric surgeons, radio-oncologists and nurses.Greater inclusion of pathologists, pediatric oncology pharmacists and dieticians into multidisciplinary care and childhood cancer training should be facilitated and resourced.Successful advocacy programs and tool kits exist in parts of Africa, but the training in advocacy is still underdeveloped.

Cost-effectiveness of running a paediatric oncology unit in Ethiopia

OBJECTIVE

To estimate the cost-effectiveness of running a paediatric oncology unit in Ethiopia to inform the revision of the Ethiopia Essential Health Service Package (EEHSP), which ranks the treatment of childhood cancers at a low and medium priority.

METHODS

We built a decision analytical model-a decision tree-to estimate the cost-effectiveness of running a paediatric oncology unit compared with a do-nothing scenario (no paediatric oncology care) from a healthcare provider perspective. We used the recently (2018-2019) conducted costing estimate for running the paediatric oncology unit at Tikur Anbessa Specialized Hospital (TASH) and employed a mixed costing approach (top-down and bottom-up). We used data on health outcomes from other studies in similar settings to estimate the disability-adjusted life years (DALYs) averted of running a paediatric oncology unit compared with a do-nothing scenario over a lifetime horizon. Both costs and effects were discounted (3%) to the present value. The primary outcome was incremental cost in US dollars (USDs) per DALY averted, and we used a willingness-to-pay (WTP) threshold of 50% of the Ethiopian gross domestic product per capita (USD 477 in 2019). Uncertainty was tested using one-way and probabilistic sensitivity analyses.

RESULTS

The incremental cost and DALYs averted per child treated in the paediatric oncology unit at TASH were USD 876 and 2.4, respectively, compared with no paediatric oncology care. The incremental cost-effectiveness ratio of running a paediatric oncology unit was USD 361 per DALY averted, and it was cost-effective in 90% of 100 000 Monte Carlo iterations at a USD 477 WTP threshold.

CONCLUSIONS

The provision of paediatric cancer services using a specialised oncology unit is most likely cost-effective in Ethiopia, at least for easily treatable cancer types in centres with minimal to moderate capability. We recommend reassessing the priority-level decision of childhood cancer treatment in the current EEHSP.

The Health Care Utilization and Medical Costs in Long-Term Follow-Up of Children Diagnosed With Leukemia, Solid Tumor, or Brain Tumor: Population-Based Study Using the National Health Insurance Claims Data

BACKGROUND

Childhood cancer survivors are at a high risk of medical consequences of their disease and treatment. There is growing information about the long-term health issues of childhood cancer survivors; however, there are very few studies describing the health care utilization and costs for this unique population. Understanding their utilization of health care services and costs will provide the basis for developing strategies to better serve these individuals and potentially reduce the cost.

OBJECTIVE

This study aims to determine the utilization of health services and costs for long-term survivors of childhood cancer in Taiwan.

METHODS

This is a nationwide, population-based, retrospective case-control study. We analyzed the claims data of the National Health Insurance that covers 99% of the Taiwanese population of 25.68 million. A total of 33,105 children had survived for at least 5 years after the first appearance of a diagnostic code of cancer or a benign brain tumor before the age of 18 years from 2000 to 2010 with follow-up to 2015. An age- and gender-matched control group of 64,754 individuals with no cancer was randomly selected for comparison. Utilization was compared between the cancer and no cancer groups by χ2 test. The annual medical expense was compared by the Mann-Whitney U test and Kruskal-Wallis rank-sum test.

RESULTS

At a median follow-up of 7 years, childhood cancer survivors utilized a significantly higher proportion of medical center, regional hospital, inpatient, and emergency services in contrast to no cancer individuals: 57.92% (19,174/33,105) versus 44.51% (28,825/64,754), 90.66% (30,014/33,105) versus 85.70% (55,493/64,754), 27.19% (9000/33,105) versus 20.31% (13,152/64,754), and 65.26% (21,604/33,105) versus 59.36% (38,441/64,754), respectively (all P<.001). The annual total expense (median, interquartile range) of childhood cancer survivors was significantly higher than that of the comparison group (US $285.56, US $161.78-US $535.80 per year vs US $203.90, US $118.98-US $347.55 per year; P<.001). Survivors with female gender, diagnosis before the age of 3 years, and diagnosis of brain cancer or a benign brain tumor had significantly higher annual outpatient expenses (all P<.001). Moreover, the analysis of outpatient medication costs showed that hormonal and neurological medications comprised the 2 largest costs in brain cancer and benign brain tumor survivors.

CONCLUSIONS

Survivors of childhood cancer and a benign brain tumor had higher utilization of advanced health resources and higher costs of care. The design of the initial treatment plan minimizing long-term consequences, early intervention strategies, and survivorship programs have the potential to mitigate costs of late effects due to childhood cancer and its treatment.

Cost-Effectiveness of Pediatric Hand International Medical Missions

PURPOSE

Limited access and resources in low- and middle-income countries leave many individuals deprived of medical care. Surgical mission trips offer a solution to provide sound surgical care to underserved areas but require a sizable financial support. Previous analyses of such trips have not included values of donated supplies and costs borne by the host country. We hypothesized that the orthopedic mission trips, utilizing the World Pediatric Project (WPP) model, can be executed in a cost-effective manner according to the World Health Organization thresholds even when considering cost to the organizations and host country.

METHODS

World Pediatric Project records for the most recent pediatric upper extremity orthopedic mission trips of 2016, 2018, and 2019 were obtained. Cost estimates were based on documentation from each of the mission trips. Total costs included the costs borne by the WPP, estimates of the value of donated supplies, and costs borne by the host country. The cost-effectiveness of the surgical mission trips was determined by the total cost and potential benefit of performing the orthopedic surgeries using disability-adjusted life years averted.

RESULTS

Three separate mission trips to St. Vincent and the Grenadines were analyzed. Forty-five pediatric patients had received surgical care. The cost was calculated to be $431.50 per disability-adjusted life years averted when only the WPP costs are considered; including donated supplies and cost borne by the host country in the total cost, the cost was $6898.10 per disability-adjusted life years averted. After comparing the cost values to the per capita gross domestic product of St. Vincent and the Grenadines, $7,463.54, the WPP mission trips were determined to be cost-effective according to the WHO-CHOICE thresholds in all 5 categories.

CONCLUSIONS

Orthopedic medical mission trips can provide cost-effective surgical treatments for the upper extremity even when the costs to the organization and host country and trip donations are considered.

Comparative treatment costs of risk-stratified therapy for childhood acute lymphoblastic leukemia in India

BACKGROUND

To evaluate the treatment cost and cost effectiveness of a risk-stratified therapy to treat pediatric acute lymphoblastic leukemia (ALL) in India.

METHODS

The cost of total treatment duration was calculated for a retrospective cohort of ALL children treated at a tertiary care facility. Children were risk stratified into standard (SR), intermediate (IR) and high (HR) for B-cell precursor ALL, and T-ALL. Cost of therapy was obtained from the hospital electronic billing systems and details of outpatient (OP) and inpatient (IP) from electronic medical records. Cost effectiveness was calculated in disability-adjusted life years.

RESULTS

One hundred and forty five patients, SR (50), IR (36), HR (39), and T-ALL (20) were analyzed. Median cost of the entire treatment for SR, IR, HR, and T-ALL was found to be $3900, $5500, $7400, and $8700, respectively, with chemotherapy contributing to 25%-35% of total cost. Out-patient costs were significantly lower for SR (p < 0.0001). OP costs were higher than in-patient costs for SR and IR, while in-patient costs were higher in T-ALL. Costs for non-therapy admissions were significantly higher in HR and T-ALL (p < 0.0001), representing over 50% of costs of in-patient therapy. HR and T-ALL also had longer durations of non-therapy admissions. Based on WHO-CHOICE guidelines, the risk-stratified approach was very cost effective for all categories of patients.

CONCLUSIONS

Risk-stratified approach to treat childhood ALL is very cost-effective for all categories in our setting. The cost for SR and IR patients is significantly reduced through decreased IP admissions for both, chemotherapy and non-chemotherapy reasons.

Cost-effectiveness of childhood cancer treatment in Egypt: Lessons to promote high-value care in a resource-limited setting based on real-world evidence

BACKGROUND

Childhood cancer in low-and middle-income countries is a global health priority, however, the perception that treatment is unaffordable has potentially led to scarce investment in resources, contributing to inferior survival. In this study, we analysed real-world data about the cost-effectiveness of treating 8886 children with cancer at a large resource-limited paediatric oncology setting in Egypt, between 2013 and 2017, stratified by cancer type, stage/risk, and disease status.

METHODS

Childhood cancer costs (USD 2019) were calculated from a health-system perspective, and 5-year overall survival was used to represent clinical effectiveness. We estimated cost-effectiveness as the cost per disability-adjusted life-year (cost/DALY) averted, adjusted for utility decrement for late-effect morbidity and mortality.

FINDINGS

For all cancers combined, cost/DALY averted was $1384 (0.5 × GDP/capita), which is very cost-effective according to WHO-CHOICE thresholds. Ratio of cost/DALY averted to GDP/capita varied by cancer type/sub-type and disease severity (range: 0.1-1.6), where it was lowest for Hodgkin lymphoma, and retinoblastoma, and highest for high-risk acute leukaemia, and high-risk neuroblastoma. Treatment was cost-effective (ratio <3 × GDP/capita) for all cancer types/subtypes and risk/stage groups, except for relapsed/refractory acute leukaemia, and relapsed/progressive patients with brain tumours, hepatoblastoma, Ewing sarcoma, and neuroblastoma. Treatment cost-effectiveness was affected by the high costs and inferior survival of advanced-stage/high-risk and relapsed/progressive cancers.

INTERPRETATION

Childhood cancer treatment is cost-effective in a resource-limited setting in Egypt, except for some relapsed/progressive cancer groups. We present evidence-based recommendations and lessons to promote high-value in care delivery, with implications on practice and policy.

Assessing the cost and economic impact of tertiary-level pediatric cancer care in Tanzania

Background

Worldwide, an estimated 400,000 children develop cancer each year. The bulk of the mortalities from these cases occur in low-and-middle-income countries (LMICs). In Sub-Saharan Africa, there is a tremendous need to strengthen the capacity of health systems to provide high-quality cancer care for children. However, a lack of data on the economic impact of cancer treatment in low-resource settings hinders its consideration as a healthcare priority. To address this gap, this study models the clinical and financial impact of pediatric cancer care in Tanzania, a lower-middle income country in East Africa.

Methods

We conducted a retrospective review of patients with cancer under the age of 19 years treated at Bugando Medical Centre from January 2010 to August 2014. Information was collected from a total of 161 children, including demographics, type of cancer, care received, and five-year survival outcomes. This data was used to calculate the number of averted disability-adjusted life-years (DALYs) with treatment. Charges for all direct medical costs, fixed provider costs, and variable provider costs were used to calculate total cost of care. The societal economic impact of cancer treatment was modeled using the value of statistical life (VSL) and human capital methods.

Findings

The total health impact for these 161 children was 819 averted DALYs at a total cost of $846,743. The median cost per patient was $5,064 ($4,746–5,501 interquartile range). The societal economic impact of cancer treatment ranged from $590,534 to $3,647,158 using VSL method and $1,776,296 using a human capital approach.

Interpretation

Despite the limitations of existing treatment capacity, economic modeling demonstrates a positive economic impact from providing pediatric cancer care in Tanzania. As many countries like Tanzania progress towards achieving Universal Health Coverage, these key economic indicators may encourage future investment in comprehensive pediatric cancer care programs in low-resource settings to achieve clinically and economically beneficial results not only for the individual patients, but for the country as a whole.

Economic Perspective of Cancer Care and Its Consequences for Vulnerable Groups

Simple Summary

For cancer patients, many different reasons can cause financial burdens and economic threads. Sociodemographic factors, rural/remote location and income are known determinants for these vulnerable groups. This economic vulnerability is related to the reduced utilization of cancer care and the impact on outcome. Financial burden has been reported in many countries throughout the world and needs to be addressed as part of the sufficient quality of cancer care.

Abstract

Within healthcare systems in all countries, vulnerable groups of patients can be identified and are characterized by the reduced utilization of available healthcare. Many different reasons can be attributed to this observation, summarized as implementation barriers involving acceptance, accessibility, affordability, acceptability and quality of care. For many patients, cancer care is specifically associated with the occurrence of vulnerability due to the complex disease, very different target groups and delivery situations (from prevention to palliative care) as well as cost-intensive care. Sociodemographic factors, such as educational level, rural/remote location and income, are known determinants for these vulnerable groups. However, different forms of financial burdens likely influence this vulnerability in cancer care delivery in a distinct manner. In a narrative review, these socioeconomic challenges are summarized regarding their occurrence and consequences to current cancer care. Overall, besides direct costs such as for treatment, many facets of indirect costs including survivorship costs for the cancer patients and their social environment need to be considered regarding the impact on vulnerability, treatment compliance and abundance. In addition, individual cancer-related financial burden might also affect the society due to the loss of productivity and workforce availability. Healthcare providers are requested to address this vulnerability during the treatment of cancer patients.

What can work and how? An overview of evidence-based interventions and delivery strategies to support health and human development from before conception to 20 years

Progress has been made globally in improving the coverage of key maternal, newborn, and early childhood interventions in low-income and middle-income countries, which has contributed to a decrease in child mortality and morbidity. However, inequities remain, and many children and adolescents are still not covered by life-saving and nurturing care interventions, despite their relatively low costs and high cost-effectiveness. This Series paper builds on a large body of work from the past two decades on evidence-based interventions and packages of care for survival, strategies for delivery, and platforms to reach the most vulnerable. We review the current evidence base on the effectiveness of a variety of essential and emerging interventions that can be delivered from before conception until age 20 years to help children and adolescents not only survive into adulthood, but also to grow and develop optimally, support their wellbeing, and help them reach their full developmental potential. Although scaling up evidence-based interventions in children younger than 5 years might have the greatest effect on reducing child mortality rates, we highlight interventions and evidence gaps for school-age children (5-9 years) and the transition from childhood to adolescence (10-19 years), including interventions to support mental health and positive development, and address unintentional injuries, neglected tropical diseases, and non-communicable diseases.

Systematic review of costs and cost-effectiveness of treatment for relapsed/refractory acute leukaemia in children and young adults

INTRODUCTION

Survival outcomes of children with relapsed/refractory (r/r) acute leukaemia remain poor. Novel expensive treatments have been developed to improve their outcomes, yet, limited evidence exists about cost-effectiveness of alternative treatment strategies.

AREAS COVERED

A systematic review was conducted to summarize the health-economic evidence about costs/cost-effectiveness of treating r/r acute leukaemia in children/young adults. We searched Medline, Embase, and Cochrane databases until August 13^th, 2021. Eligible articles included peer-reviewed original studies addressing r/r paediatric/young-adult acute lymphoblastic leukaemia (ALL), and acute myeloid leukaemia (AML). Quality assessment was conducted using Consolidated Health Economics Evaluation Reporting Standards (CHEERS) checklist.

EXPERT OPINION

The majority of papers focused on CAR-T cell therapy, which is still a novel treatment for r/r ALL, and was found to be cost-effective, yet, there remain concerns over its long-term effectiveness, affordability, and equity in access. The next best treatment option is Blinatumomab, followed by Clofarabine therapy, whereas FLA-IDA salvage chemotherapy provides least value for money. The quality of evidence is moderate to high, with limited generalizability of findings due to high variability in outcomes obtained from modelling studies. Limited studies evaluated r/r AML. We provide recommendations to deliver cost-effective treatments in real-world contexts, with implications for healthcare policy and practice.

Childhood Cancers Misdiagnosed as Tuberculosis in a High Tuberculosis Burden Setting

BACKGROUND

Tuberculosis (TB) and childhood cancers have overlapping presentations and malignancies may be misdiagnosed as TB in high TB-burden settings.

METHODS

This retrospective study investigated the diagnosis of TB in children with cancer registered in the Tygerberg Hospital Childhood Tumor Registry from 2008 to 2018. We studied children on anti-tuberculosis treatment (ATT) at cancer diagnosis or diagnosed with TB within 1 month of cancer diagnosis. We describe the circumstances and extent of this misdiagnosis, quantify the delay in therapy and document the outcomes of these children.

RESULTS

Twenty-seven of 539 (5%) children in the registry started ATT before cancer diagnosis. Both pulmonary and extrapulmonary TB complicated the cancer diagnosis. Of the 27 patients on ATT at cancer diagnosis, 22 (81%) had contact with a TB case and in 6 of 12 children (50%) a tuberculin skin test was positive. At cancer diagnosis, 16/27 (59%) children had chest radiograph changes interpreted as TB with 11/27 (41%) regarded as suggestive of TB on expert review. The median diagnostic delay between TB and cancer diagnoses was 25 days (interquartile range 3.5-58). Of 539 children with cancer, 204 (38%) died of cancer, including 18/30 (60%) children on ATT at cancer diagnosis or diagnosed with TB within 1 month of cancer diagnosis (odds ratio 2.6; 95% confidence interval: 1.2-5.4; P = 0.012).

CONCLUSIONS

The clinical and radiologic overlap of TB and cancer causes diagnostic confusion in a significant number of children with cancer and may contribute to increased mortality.

Childhood cancer hospital resource utilization and costs in Egypt, 2013-2017; patterns, trends, and associated factors for 8886 patients from Children's Cancer Hospital, Egypt

INTRODUCTION

There is a lack ofevidence about resource use and costs of childhood cancer care in Egypt. Knowledge about resource use/costs can help in better resource planning to improve care and outcomes efficiently. In this study, we estimated patterns and trends of hospital resource use and costs for children with cancer (n = 8886, aged 0-18 years) treated at Children's Cancer Hospital, Egypt (CCHE), between 2013 and 2017, by ICCC-3 groups, at one and three years post-diagnosis.

METHODS

We estimated costs from the healthcare provider perspective, expressed in USD 2019. We also studied resource use/cost trends, and factors associated with inpatient days and costs.

RESULTS

For all cancers combined, median costs were $14,774 (IQR: $6,559-$23,738) at one year and $19,799 (IQR: $8,921-$34,204) at three years post-diagnosis. Median inpatient days were 38 days (IQR: 17-60) at one year, and 43 days (IQR: 20-74) at three years post-diagnosis. Patients with acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), and neuroblastoma imposed the greatest financial burden on CCHE, representing 53.1% of total costs. AML patients had the highest costs/resource use of all childhood cancers. Cost trends decreased by 2.9% (P < 0.001) for all cancers combined, due to economic instability in Egypt between 2013 and 2017. The use of IV supportive drugs increased by 24.3% (P < 0.001) over time for children with solid tumors.

CONCLUSION

These findings will inform hospital resource planning and budgeting to promote value in care delivery, with implications for pediatric oncology practice and policy in Egypt/CCHE. Estimated costs provide the foundation for cost-effectiveness analysis.

Treatment of childhood acute lymphoblastic leukemia in Iraq: a 17-year experience from a single center

We performed a retrospective analysis of 1415 acute lymphoblastic leukemia children diagnosed between January 2000 and December 2016 at Children Welfare Teaching Hospital, Baghdad, Iraq. Patients were divided into three cohorts according to treatment period (2000-2005; 2006-2011; 2012-2016). Treatments were based on modified-UKALL protocols; a steroid-pre-phase was introduced from September 2008. The overall complete remission was 86%, increased from 80% to 91% in the last period. Early deaths occurred in 10%, decreasing to 6%, overtime. Relapses were 23%; toxic deaths and abandonment 8% and 13%, respectively. At a median follow-up of 65.3 months, with abandonment considered as an event, the 5-year overall survival (OS) and event-free survival were 62.2% and 46.3%, statistically influenced by treatment period (5-year OS 62.6%, 59.1%, 66.3%; p=.057, respectively). Though pediatric ALL survival in Iraq is still below that observed in high income countries, survival rates progressively improved. Toxic deaths remain an important cause of failure.

Health system determinants of access to essential medicines for children with cancer in Ghana

Background

Evidence of the context-specific challenges related to childhood cancer drug (CCD) access is vital to improving outcomes for children with cancer in low- and middle-income countries, such as Ghana. We sought to determine the availability and cost of essential CCD in Ghana and identify the underlying determinants of access.

Methods

Our study integrated quantitative data on drug prices and availability with qualitative insights into health system and sociopolitical determinants of CCD access in Ghana. We analysed retrospective monthly price and stock data for 41 cancer and supportive care drugs on the WHO Essential Medicines List (EML) from private retail and public institutional pharmacies. Non-parametric analyses evaluated relationships between drug price and availability, and impacts of drug class and formulation on availability and procurement efficiency. We assessed the determinants of drug access through thematic analysis of policy documents and semi-structured interviews (n=21) with key health system stakeholders.

Results

Ghana lists only 47% of essential CCD on its National EML, revealing gaps in domestic formulary inclusion. Stock-outs occurred for 88% of essential CCD, with a 70-day median stock-out duration; 32% had median price ratios above internationally-accepted efficiency thresholds. Drugs procured inefficiently were more susceptible to stock-outs (p=0.0003). Principal determinants of drug access included: (1) lack of sociopolitical priority afforded childhood cancer and (2) the impact of policy and regulatory environments on drug affordability, availability and quality. Establishment of a population-based cancer registry, a nationally-coordinated procurement strategy for CCD, public financing for childhood cancer care and policies to control drug costs emerged as priority interventions to improve drug access in Ghana.

Conclusion

Our study provides context-specific evidence to enable responsive policy development for efficient drug procurement and supply management in Ghana and establishes a rigorous approach to the analysis of childhood cancer drug access in similar health system settings.

Economic Evaluations of Breast Cancer Care in Low- and Middle-Income Countries: A Scoping Review

BACKGROUND

Understanding the cost of delivering breast cancer (BC) care in low- and middle-income countries (LMICs) is critical to guide effective care delivery strategies. This scoping review summarizes the scope of literature on the costs of BC care in LMICs and characterizes the methodological approaches of these economic evaluations.

MATERIALS AND METHODS

A systematic literature search was performed in five databases and gray literature up to March 2020. Studies were screened to identify original articles that included a cost outcome for BC diagnosis or treatment in an LMIC. Two independent reviewers assessed articles for eligibility. Data related to study characteristics and methodology were extracted. Study quality was assessed using the Drummond et al. checklist.

RESULTS

Ninety-one articles across 38 countries were included. The majority (73%) of studies were published between 2013 and 2020. Low-income countries (2%) and countries in Sub-Saharan Africa (9%) were grossly underrepresented. The majority of studies (60%) used a health care system perspective. Time horizon was not reported in 30 studies (33%). Of the 33 studies that estimated the cost of multiple steps in the BC care pathway, the majority (73%) were of high quality, but studies varied in their inclusion of nonmedical direct and indirect costs.

CONCLUSION

There has been substantial growth in the number of BC economic evaluations in LMICs in the past decade, but there remain limited data from low-income countries, especially those in Sub-Saharan Africa. BC economic evaluations should be prioritized in these countries. Use of existing frameworks for economic evaluations may help achieve comparable, transparent costing analyses.

IMPLICATIONS FOR PRACTICE

There has been substantial growth in the number of breast cancer economic evaluations in low- and middle-income countries (LMICs) in the past decade, but there remain limited data from low-income countries. Breast cancer economic evaluations should be prioritized in low-income countries and in Sub-Saharan Africa. Researchers should strive to use and report a costing perspective and time horizon that captures all costs relevant to the study objective, including those such as direct nonmedical and indirect costs. Use of existing frameworks for economic evaluations in LMICs may help achieve comparable, transparent costing analyses in order to guide breast cancer control strategies.

Training pediatric hematologist/oncologists for capacity building in Ethiopia

PURPOSE

A considerable barrier to global pediatric oncology efforts has been the scarcity and even absence of trained professionals in many low- and middle-income countries, where the majority of children with cancer reside. In 2013, no dedicated pediatric hematology-oncology (PHO) programs existed in Ethiopia despite the estimated annual incidence of 6000-12000 cases. The Aslan Project initiative was established to fill this gap in order to improve pediatric cancer care in Ethiopia. A major objective was to increase subspecialty PHO-trained physicians who were committed to practicing locally and empowered to lead programmatic development.

METHODS

We designed and implemented a PHO training curriculum to provide a robust educational and clinical experience within the existing resource-constrained environment in Ethiopia. Education relied on visiting PHO faculty, a training attachment abroad, and extraordinary initiative from trainees.

RESULTS

Four physicians have completed comprehensive PHO subspecialty training based primarily in Ethiopia, and all have remained local. Former fellows are now leading two PHO centers in Ethiopia with a combined capacity of 64 inpatient beds and over 800 new diagnoses per year; an additional former fellow is developing a pediatric cancer program in Nairobi, Kenya. Two fellows currently are in training. Program leadership, teaching, and advocacy are being transitioned to these physicians.

CONCLUSIONS

Despite myriad challenges, a subspecialty PHO training program was successfully implemented in a low-income country. PHO training in Ethiopia is approaching sustainability through human resource development, and is accelerating the growth of dedicated PHO services where none existed 7 years ago.

Shortages and price variability of essential cytotoxic medicines for treating children with cancers

Introduction

Low-income and middle-income countries (LMICs) face the largest burden of mortality from childhood cancers with limited access to curative therapies. Few comparative analyses across all income groups and world regions have examined the availability and acquisition costs of essential medicines for treating cancers in children.

Methods

A cross-sectional survey involved countries in five income groups—low-income (LIC), lower-middle-income (LMC), upper-middle-income (UMC), two high-income country groups (HIC1, HIC2). Physicians and pharmacists reported institutional use, availability, stock outs and prices (brand and generic products) of 34 essential medicines. Price comparisons used US$, applying foreign exchange rates (XR) and purchasing power parity (PPP) adjustments. Medicine costs for treating acute lymphoblastic leukaemia (ALL), Burkitt lymphoma (BL) and Wilms tumour (WT) were calculated (child 29 kg, body surface area 1 m²). Comparisons were conducted using non-parametric Kruskal-Wallis tests.

Results

Fifty-eight respondents (50 countries) provided information on medicine use, availability and stock outs, with usable price data from 42 facilities (37 countries). The extent of use of International Society of Paediatric Oncology core and ancillary medicines varied across income groups (p<0.0001 and p=0.0002 respectively). LMC and LIC facilities used fewer medicines than UMC and HIC facilities. UMC and LMC facilities were more likely to report medicines not available or stockouts.

Medicine prices varied widely within and between income bands; generic products were not always cheaper than brand equivalents. PPP adjustment showed relatively higher prices in UMC and LMC facilities for some medicines. Medicine costs were highest in HICs for ALL (p=0.0075 XR; p=0.0178 PPP-adjusted analyses) and WT (p =<0.0001 XR; p=0.0007 PPP-adjusted). Medicine costs for BL were not significantly different.

Conclusion

Problems with the availability of essential medicines, dependable supply chains, confidential medicine prices and wide variability in treatment costs contribute to persistent challenges in the care of children with treatable cancers, especially in LMICs.

The cost-effectiveness of treating childhood cancer in 4 centers across sub-Saharan Africa

BACKGROUND

The treatment of childhood cancer often is assumed to be costly in African settings, thereby limiting advocacy and policy efforts. The authors determined the cost and cost-effectiveness of maintaining childhood cancer centers across 4 hospitals throughout sub-Saharan Africa.

METHODS

Within hospitals representing 4 countries (Kenya, Nigeria, Tanzania, and Zimbabwe), cost was determined either retrospectively or prospectively for all inputs related to operating a pediatric cancer unit (eg, laboratory costs, medications, and salaries). Cost-effectiveness was calculated based on the annual number of newly diagnosed patients, survival rates, and life expectancy.

RESULTS

Cost per new diagnosis ranged from $2400 to $31,000, attributable to variances with regard to center size, case mix, drug prices, admission practices, and the treatment abandonment rate, which also affected survival. The most expensive cost input was found to be associated with medication in Kenya, and medical personnel in the other 3 centers. The cost per disability-adjusted life-year averted ranged from 0.3 to 3.6 times the per capita gross national income. Childhood cancer treatment therefore was considered to be very cost-effective by World Health Organization standards in 2 countries and cost-effective in 1 additional country. In all centers, abandonment of treatment was common; modeling exercises suggested that public funding of treatment, additional psychosocial personnel, and modifications of inpatient policies would increase survival rates while maintaining or even improving cost-effectiveness.

CONCLUSIONS

Across various African countries, childhood cancer treatment units represent cost-effective interventions. Cost-effectiveness can be increased through the control of drug prices, appropriate policy environments, and decreasing the rate of treatment abandonment. These results will inform national childhood cancer strategies across Africa.

Quality of Life in Orthodontic Cancer Survivor Patients-A Prospective Case-Control Study

Background: The aim of the study was to compare the quality of life (QoL) of cancer survivors with a control group of healthy subjects before, during, and after the orthodontic treatment. Methods: Consecutive cancer survivors (40 people) who were looking for orthodontic treatment between 2008 and 2015 were enrolled into the study. Healthy orthodontic patients matched for age (±4 years), sex, and malocclusion served as controls. The 14-item version of the Oral Health Impact Profile was used to assess the effect of orthodontic treatment on QoL before, during, and after the orthodontic treatment. Results: There were no significant differences between both groups regarding the cast model, cephalometric analysis, and photographic documentation analysis. There was a significant worsening of QoL after the onset of the orthodontic treatment with a significant improvement after the treatment. Male cancer survivor patients reported significantly lower QoL during the treatment time, which was not observed in the male control group. Conclusions: The outcome of orthodontic treatment in cancer survivors did not differ from the healthy orthodontic patients. The orthodontic treatment had an impact on the oral health quality of life both in the cancer and the control groups with a significantly higher impact in male cancer survivor patients.
