Background: Future-proofing national policies/programmes to consider emergent needs and evidence via systems and policy science can prevent critical implementation failures, and avoid misallocations of scarce resources, particularly in complex policy arenas such as childhood cancer control.    
 
Objectives: With the approaching global target to save one million more children and adolescents by 2030, exemplars of efforts engaging multi-sectoral stakeholders for adaptive cancer control as part of the global NexPoS (Nexus of Policies and Systems) network are analyzed.
 
Methods: A programmatic and strategic synthesis and analysis of national childhood cancer policy/programme strengthening initiatives has been conducted.  Enablers and accelerators to future-proof policies/programmes to address evolving needs across initiatives are identified. 
 
Results:  Evidence-informed national policy and programme strengthening efforts for childhood cancer control have engaged policymakers, implementers, researchers, multi-sectoral stakeholders and advocates from 86 countries across all WHO regions and World Bank economies.  Global goods and bespoke tools, including SJCARES Policies and Systems, have been co-designed with the St. Jude Global Alliance and NexPoS global network to bridge evidence-to-policy and policy-to-action gaps.  SJCARES Policies and Systems websites, including the Policy Monitor, which visualizes a curated set of over 1,000 national cancer-related policy documents in 46 languages totaling 61,000 pages from 197 countries/territories, have been accessed by users from 84 countries/territories. Collaborative outputs in 2025 include 10 global consensus statements on the unique and pathfinding aspects of childhood cancer control in systems strengthening, and an applied referral pathways framework examining levers and flows for children with cancer considering systems-wide needs, involving over 150 experts from 42 countries.  Selected from over 700 applicants from 75 countries, 70 Ministry-designated teams from 39 countries across all regions and economies have participated in cohort-based training since 2022 via a 7-month virtual knowledge exchange program on National Cancer Control Planning integrating Children, Adolescents and Young Adults (NCCP iCAYA), with participants from 80 countries engaged in open learning sessions in 2025.
 
Foundational enablers to future-proof policies/programmes for childhood cancer control across these efforts include investing in current and next-generation leaders and local champions, and fostering applications of participatory policy and systems science including anticipatory governance and attentiveness to mindsets and financing mechanisms. Global initiatives including the Global Initiative for Childhood Cancer, ChildGICR, and Rays of Hope for Childhood Cancer provide shared language, frameworks, and entry points for multi-sectoral collaboration and learning systems for sustainable impact.  Accelerators to future-proof policies/programmes include extending applications of data science and artificial intelligence (AI) for policy synthesis, analysis, application, and innovation, and facilitating country-level priority-setting across 12+ areas of policy intersection/integration identified via NCCP iCAYA. Together, AI?enabled policy intelligence, analytic systems, and intentionally designed learning communities can form continuous evidence?to?policy?to?practice feedback loops essential to future?proof systems. Priority intersections include needs across catastrophic conditions, and readiness to gauge and respond to shifting epidemiology, innovation, and community needs. 
 
Conclusions/Implications: Future-proofing evidence-informed policies/programmes is critical to effectively anticipate and address the dynamic needs of children and adolescents with cancer.  Enablers and accelerators identified to date across global collaboratives offer keys to achieve sustainable, multigenerational impact.
