Welcome to our community of over 3,000 paediatric haematology/oncology professionals

The International Society of Paediatric Oncology (SIOP) was established on November 6, 1969, by a small group of specialists at the Institut Gustave-Roussy in Paris, with the mission to advance the study and care of children with cancer. This goal was expanded to include the advancement of basic research as well as clinical studies, the inclusion of nurses, other health professionals and parents, and the organization of teaching and outreach programs to improve childhood cancer care in underdeveloped communities.

Today, SIOP is a truly global, multifaceted organization and is the only global multidisciplinary society entirely devoted to paediatric and adolescent cancer. The Society has over 3,000 members worldwide including doctors, nurses, allied healthcare professionals, scientists and researchers etc. Our members are dedicated to increasing knowledge about all aspects of childhood cancer.

This is a Catalan Human Tower Human, or “Castell”, where the smallest child gets to stand at the very top of the pyramid and continues to feel safe and supported. This a beautiful reminder of how much effort goes in childhood cancer care and how our successes are the results of a big team effort! We are all working together to achieve that magnificent endpoint in the foreseeable future were no child should die of cancer: cure for more, care for all.
