Oncology Information Systems (OIS) enable data capture, management, and utilisation to support service delivery, quality assurance, and research. International initiatives, largely in high- income settings, have demonstrated the value of data harmonisation. However, half of global cancer cases are diagnosed in the Asia-Pacific (APAC) region1, where OIS maturity varies widely. Many low- and middle-income countries (LMICs) remain in earlier stages of implementation, often using legacy or limited-functionality systems. This poses challenges

sophisticated technology, and skilled personnel. During crises—such as pandemics, cyberattacks, energy shortages, or armed conflict—these dependencies render radiotherapy services particularly vulnerable. Germany’s technologically advanced but decentralised health system faces specific challenges in coordinating an effective response. Material/Methods: This narrative review synthesises peer-reviewed evidence, WHO and IAEA reports, and European policy documents on radiotherapy system performance under crisis conditions. It analyses governance, technological, workforce, and ethical dimensions of resilience within Germany’s federal structure, integrating lessons from recent global emergencies. Results: Germany possesses one of Europe’s densest radiotherapy networks and a robust workforce base. However, fragmented governance, regional variation in licensure, and inconsistent digital interoperability impede coordinated crisis response. Core vulnerabilities include dependence on international supply chains, cybersecurity risks, and limited mechanisms for workforce mobility across Länder. Experiences from pandemics, wars, and natural disasters demonstrate that resilience depends on cross-sectoral planning, ethical preparedness, and digital integration. Conclusion: Establishing a Central Coordination Office for Radiation Oncology, unified emergency licensing procedures, and interoperable data systems would strengthen continuity of care during crises. Embedding radiotherapy into national critical-infrastructure policy and civil-protection planning would ensure priority access to energy, logistics, and digital resources. Germany’s framework can serve as a model for resilient radiotherapy governance across Europe.
