SIOP is the only global multidisciplinary society entirely devoted to paediatric and adolescent cancer.
The society has over 1800 members worldwide including doctors, nurses, other health-care professionals, scientists and researchers. Our members are dedicated to increasing knowledge about all aspects of childhood cancer.

SIOP’s vision is that no child should die of cancer and that cure can be achieved with no or minimal late effects.


  • By advocating globally on behalf of patients and families to ensure that every child and adolescent with cancer has access to state of the art diagnosis, treatment and care
  • By providing training opportunities for all childhood and adolescent cancer care providers worldwide on the latest clinical and scientific advances through meetings, networking, and educational outreach for continuing professional development
  • By promoting and advancing basic, clinical, and other research, and by supporting collaborative opportunities and translating scientific discovery to improve the outcomes for children and adolescents with cancer
  • By supporting those caring for children and adolescents with cancer and to provide them with the best curative and palliative therapies
  • By advocating appropriate long-term follow-up for survivors

SIOP Strategy 2021-2015

Over the past 12 months, the SIOP Board and the SIOP membership have been working hard on the development of the new SIOP Strategy for the next 5 years. Initial brainstorming took place in June 2019, followed by more discussions at the Lyon 2019 Congress and small group work by the Board members during the Spring & Summer of 2020. The final stage of the strategic plan development is a review of the draft Strategy by the membership, which is taking place in September 2020. The new Strategy is scheduled to be announced during the Annual Business Meeting of the society on October 16, 220. The Strategy enters in effect on January 1, 2021.
