54th Annual SIOP Congress that will take place in Barcelona, Spain from Sep 28 - Oct 1, 2022 will be the place to hear the latest research findings in our field and to catalyse new ideas, generated by the multi-disciplinary attendance for which we are renowned. Furthermore, the pre-Congress Educational Day, with parallel sessions organised by the Local Organising Committee, the Young SIOP Network, Nursing Network, Paediatric Psycho-oncology Network and the Global Health Network provides an excellent forum to meet with your peers and hear about opportunities for networking and collaboration. All sessions will be live-streamed from Barcelona via a special virtual platform. The sessions will be available to watch for the next 3 months after the end of the Congress for all registered participants. CME Credits are provided to the participants,
