SIOP Europe (European Society for Paediatric Oncology)
The European paediatric oncology society and the umbrella for the European clinical trial groups that treat most children with cancer on shared protocols.
Also called: SIOPESIOPInternational Society of Paediatric Oncology
Overview
SIOP Europe is the European branch of the International Society of Paediatric Oncology (SIOP, founded 1969) and the only pan-European organisation representing children's cancer professionals. It coordinates the European Clinical Trial Groups for leukaemia, neuroblastoma (SIOPEN, whose HR-NBL1 trial defined high-risk neuroblastoma therapy), brain tumours, renal tumours, sarcomas and lymphomas, and runs the Strategic Plan for children's cancer with the European Parliament. SIOPE advocates on the EU Paediatric Regulation, ACCELERATE platform for paediatric drug development, and cross-border access to trials, and organises the annual SIOP Europe congress. SIOP itself is a global society with its annual congress and PODC programme for low- and middle-income countries.
