Dear Friends and Colleagues,
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.
Amsterdam’s accessibility and central location in Europe make it an ideal setting for a truly global gathering. We are thrilled to welcome experts and practitioners from across the world, and we anticipate robust participation from all regions. This year’s congress will include more biological, translational and clinical research and will feature specific tracks and sessions designed to foster cross-regional collaboration and knowledge-sharing, especially as we continue our commitment to the WHO Global Initiative on Childhood Cancer and the PARC programme.
As part of our dedication to inclusivity and supporting the next generation of paediatric oncology leaders, we are excited to offer scholarships for Young SIOP members from low- and middle-income countries. We encourage all eligible applicants to apply, and we will be sharing further details soon on how you can be part of this enriching congress experience.
The 2025 congress will prioritise meaningful in-person interactions to spark ideas and collaborations, while offering recorded content for those unable to attend.
As the SIOP Congress continues to grow in scope and impact, we are confident that this year’s gathering in Amsterdam will set a new standard for excellence, inclusion, and discovery. Join us in making the 2025 Congress an unforgettable chapter in our shared journey towards a world where every child with cancer has the chance to thrive.
Your presence, insights, and enthusiasm make each congress an event to remember, and together, we will ensure the 2025 Congress in Amsterdam is nothing short of historic.
With warm regards,
 Dr Guillermo Luis Chantada SIOP President |  Dr Rob Pieters Local Organising Committee Chair |  Dr Gertjan Kaspers Local Organising Committee Chair |  Dr Asim Belgaumi Scientific Committee Chair |
