The development of artificial intelligence in cancer research relies on access to extensive, high-quality imaging datasets. However, data fragmentation, heterogeneity and privacy concerns present significant challenges. The EUropean Federation for CAncer IMages (EUCAIM) initiative aims to overcome these obstacles by establishing a federated European infrastructure for cancer imaging. This effort, aligned with Europe's Beating Cancer Plan, seeks to enhance AI-driven diagnostics, facilitate collaboration among researchers and ensure compliance with ethical and legal standards. The initiative builds upon established European research infrastructures and AI networks to create a structured and unified approach to cancer imaging. By addressing issues of data accessibility and interoperability, EUCAIM enables researchers and clinicians to leverage a vast repository of imaging data while ensuring adherence to FAIR (Findability, Accessibility, Interoperability and Reusability) principles.
A Federated Approach to Cancer Imaging
EUCAIM integrates diverse cancer image repositories across Europe, establishing a structured and standardised infrastructure known as Cancer Image Europe. This initiative builds upon existing research infrastructures and AI networks to create a cohesive system for data sharing. By implementing a hybrid model that combines centralised and federated components, EUCAIM ensures that data holders retain sovereignty while contributing to a unified platform. The system allows researchers to access metadata, perform federated searches and utilise AI tools for analysis within a secure processing environment. The federated model improves interoperability, ensuring that diverse datasets from hospitals, biobanks and research institutions can be harmonised for AI training and validation.
The infrastructure also supports multidisciplinary engagement, involving key stakeholders such as public authorities, screening programmes, hospitals and innovators. Through this collaborative framework, EUCAIM facilitates the development of clinical decision-support systems that enhance precision medicine. To achieve this, the initiative employs common data models, standardisation protocols and quality control measures, ensuring that imaging data remains consistent, well-annotated and usable across different research settings. Additionally, EUCAIM integrates genomics, pathology and molecular data, enabling researchers to explore multi-dimensional correlations in cancer imaging. The FAIR-compliant approach ensures that all data is accessible while preserving security, traceability and adherence to legal standards.
Ethical and Legal Considerations in Data Sharing
Ensuring compliance with ethical and legal frameworks is central to EUCAIM’s mission. The initiative operates under strict data governance principles, integrating anonymisation techniques, authentication and authorisation mechanisms and risk-based privacy safeguards. Data access is managed through an approval process overseen by an Access Committee, ensuring transparency and accountability in the use of sensitive patient information. These measures support the integrity of research while fostering trust among data providers and end users.

EUCAIM aligns closely with the European Health Data Space (EHDS), reinforcing its role in establishing secure and responsible data-sharing practices. The infrastructure includes privacy-preserving federated learning services, enabling AI training without compromising patient confidentiality. Furthermore, data holders have the flexibility to contribute either by transferring data to EUCAIM’s secure repositories or maintaining local control within a federated network. This approach ensures that data remains traceable and ethically managed while supporting diverse research needs.
Beyond data privacy, EUCAIM incorporates risk-based compliance mechanisms, ensuring that AI development adheres to ethical principles and General Data Protection Regulation (GDPR) requirements. Through its Authentication and Authorisation Infrastructure (AAI), the initiative enables controlled access to imaging data, maintaining oversight of data usage while preventing unauthorised access. These legal and ethical safeguards are instrumental in promoting responsible innovation, enabling researchers to develop AI-driven cancer diagnostics without breaching patient rights.
Sustaining and Expanding the EUCAIM Initiative
The long-term viability of EUCAIM depends on its ability to engage stakeholders, expand data access and maintain operational sustainability. The initiative encourages participation through a structured engagement framework, offering training and support to data providers. A multi-tiered interoperability model enables different levels of data integration, allowing repositories to gradually align with EUCAIM’s standards. Additionally, the initiative fosters collaborations with patient associations, hospitals and policymakers, ensuring that cancer imaging research remains patient-centric and aligned with real-world healthcare needs.
A comprehensive sustainability plan has been established to secure funding, define business models and ensure continued integration with evolving digital infrastructures. The initiative explores various revenue models, including subscription-based access and pay-per-use frameworks, ensuring financial sustainability while maintaining accessibility for researchers. Beyond its initial phase, EUCAIM aims to evolve into a long-term European Digital Infrastructure Consortium (EDIC), ensuring its continued role in advancing AI-driven cancer diagnostics.
By promoting interoperability and standardisation, EUCAIM facilitates the adoption of AI-driven solutions, ensuring that its impact extends beyond the project’s initial scope. The initiative’s centralised governance hub oversees compliance, data quality and participation guidelines, ensuring that all stakeholders operate within a well-defined legal and ethical framework. Furthermore, EUCAIM continues to integrate new datasets and AI tools, expanding its utility for researchers, clinicians and innovators across Europe.
EUCAIM represents a transformative step in European cancer research, addressing the challenges of data fragmentation, privacy concerns and interoperability. By establishing a federated imaging infrastructure, the initiative enhances AI-driven diagnostics, fosters collaboration and upholds ethical and legal standards. With a clear roadmap for sustainability and expansion, EUCAIM is set to shape the future of precision medicine, accelerating innovation in cancer detection and treatment. Through its federated model, multidisciplinary engagement and commitment to ethical AI, the initiative serves as a foundation for next-generation cancer imaging research, ensuring that clinicians and researchers have the resources they need to advance patient care and scientific discovery.
