Use Case 2 Validation & Evaluation Workshop on Prostate Cancer (Phase 2), 6 March 2026

KU Leuven and University of Turku hosted the Use Case 2 Validation & Evaluation Workshop for Phase 2 focused on prostate cancer. It brought together researchers, clinicians, and technology partners to review progress and gather feedback on its latest innovations. 

The workshop demonstrated an integrated pipeline combining synthetic data generation, data harmonization, and federated learning, aimed at improving clinical decision in prostate cancer, particularly in predicting lymph node invasion and reducing unnecessary biopsies. Participants were introduced to new AI-assisted tools for mapping heterogeneous hospital data into a common standard, as well as distributed machine learning approaches that enable model training across institutions without sharing sensitive patient data. A key focus of the workshop was to evaluate the synthetic data with novel methods presented to assess not only model performance but also data fidelity and robustness. 

In parallel, new techniques for generating and evaluating longitudinal patient data highlighted the importance of preserving temporal patterns in clinical datasets.

The workshop also featured the Health Data Hub, a secure, federated ecosystem aligned with emerging European regulations, designed to enable trusted data sharing, service deployment, and collaboration across stakeholders.
