It is with great pleasure and anticipation that we invite you to join us for the 57th Annual SIOP Congress in Amsterdam, the Netherlands, from 20-23 October 2025. As we gather in this vibrant and historic city, we look forward to an enriching congress experience that celebrates our shared mission to advance childhood cancer care globally.

The Local Organising Committee, under the guidance of Dr Rob Pieters and Dr Gertjan Kaspers has worked tirelessly to prepare a congress that showcases the best of Amsterdam’s charm alongside an inspiring programme that will challenge and stimulate our thinking. From our opening to our closing session, the 2025 Congress will present exceptional opportunities for networking, collaboration, and professional growth.

The Scientific Committee has once again curated an outstanding programme, featuring internationally renowned speakers and a diverse array of symposia addressing the most pressing issues in paediatric oncology today. Whether you are new to our congress or a returning delegate, you will find the programme to be both intellectually rewarding and practically valuable, reflecting the latest advances and global trends in childhood cancer research and care.
