Abstract
BACKGROUND Approximately 90% of children with cancer live in low-income and middle-income countries (LMICs), where 5-year survival is lower than 20%. Treatment-related mortality in high-income countries is approximately 3-5%; however, in LMICs, treatment-related mortality has been reported in up to 45% of children with cancer. This study aimed to systematically explore the burden of treatment-related mortality in children with cancer in LMICs and to explore the association between country income level and treatment-related mortality. METHODS For this systematic review and meta-analysis we identified articles published between Jan 1, 2010, and June 22, 2021, describing treatment-related mortality in paediatric patients (aged 0-21 years) with cancer in LMICs. We searched PubMed, Trip, Web of Science, Embase, and the WHO Global Metric Index databases. The search was limited to full-text articles and excluded case reports (<10 patients) and haematopoietic stem-cell transplantation recipients. Two reviewers independently screened studies for eligibility, extracted data from included publications, and evaluated data quality. Random and mixed-effects models were used to estimate treatment-related mortality burden and trends. The Cochran-Q statistic was used to assess heterogeneity between studies. This study is registered on PROSPERO (CRD42021264849). FINDINGS Of 13 269 identified abstracts, 501 studies representing 68 351 paediatric patients with cancer were included. The treatment-related mortality estimate was 6·82% (95% CI 5·99-7·64), accounting for 30·9% of overall mortality (4437 of 14 358 deaths). Treatment-related mortality was inversely related to country income. Treatment-related mortality was 14·19% (95% CI 9·65-18·73) in low-income countries, 9·21% (7·93-10·49) in lower-middle-income countries, and 4·47% (3·42-5·53) in upper-middle-income countries (Cochran-Q 42·39, p<0·0001). In upper-middle-income countries, the incidence of treatment-related mortality decreased over time (slope -0·002, p=0·0028); however, outcomes remained unchanged in low-income (p=0·21) and lower-middle-income countries (p=0·16). INTERPRETATION Approximately one in 15 children receiving cancer treatment in LMICs die from treatment-related complications. Although treatment-related mortality has decreased in upper-middle-income countries over time, it remains unchanged in LMICs. There is an urgent need for targeted supportive care interventions to reduce global disparities in childhood cancer survival.

Abstract
Background The recent implementation of novel therapies has accelerated progress in pediatric cancer care. Despite the significantly poorer survival of patients in low- and middle-income countries (LMICs), administation complexities and other significant resource barriers have limited the translation of these novel therapies in these regions. This study aims to develop a model that can be used to support the implementation of novel therapies, such as blinatumomab (bispecific antibody therapy for B-cell acute lymphoblastic leukemia [B-ALL]) in LMIC centers, with the long-term goal of developing an implementation framework for similar future efforts. Methods In this study, mixed methods will be applied to understand the key contextual considerations that can be accounted for through a training program and prospectively designed implementation activities. The Consolidated Framework for Implementation Research will guide the activities related to implementation evaluation in parallel with a drug donation program. A multidisciplinary research team comprising high- and low-middle income healthcare professionals, industry, and implementation scientists has been assembled with the common goal of improving safe access to blinatumomab. To assess the factors affecting blinatumomab administration, semi-structured interviews with diverse collaborators and quantitative assessments of organizational characteristics will be conducted, together with quantitative and qualitative assessments of feasibility, acceptability, appropriateness, and cost of blinatumomab implementation. A quantitative assessment of stakeholder perceptions of different implementation strategies used as part of the multifaceted approach will also be performed. Finally, we will examine the key domains and processes used and construct the implementation roadmap for translation of novel therapies. Discussion This study will rigorously develop an implementation roadmap for translation of novel therapies in low-resource settings. The knowledge gained in the formative assessment will reveal the priority areas and key implementation strategies. Thereby, the resultant roadmap will facilitate future scale-out strategies for novel therapies in LMICs, thus increasing access, building capacity for management, and ultimately improving the care for children in LMICs.
