About the programme

The SIOP Europe Annual Meeting 2025 is a joint meeting of different European Clinical Trials Groups, SIOPE Working Groups, Young Oncologists and Parent & Survivor representatives.

The meeting format is unique: it includes novel session formats, interactive workshops and forums empowering the working groups to debate and disseminate the outcomes of the high quality clinical and basic research carried out in Europe. 

18 European Clinical Trial Groups, each specialising in one or more tumour type or disease, will hold their open and joint sessions during the upcoming SIOPE Annual Meeting to facilitate good research practice exchange amongst European and international co-operative groups.

The meeting is structured to allow the liquid tumour groups and solid tumour groups to meet within their groups. However, the aim of the Annual Meeting is to create ample opportunities for networking and learning through the organisation of joint sessions. On Wednesday, the middle day of the Annual Meeting, we plan an exciting programme of plenary sessions on cross-tumour topics. 

The scientific session topics will include recent outcomes from clinical trials and advances in diagnosis and therapy for different paediatric cancers, presentations of guidelines, debates on the use of artificial intelligence, epidemiology of childhood cancer, drug safety, radiation oncology and data protection but also many sessions co-organized by our long-term partner CCI Europe on communication, patient involvement, breaking taboos, informed consent and other essential topics.
