Abstract submission to the SIOP Congress are open until 5th April 2016. Presentations of large translational works are considered as major quality criteria, abstracts should cover aspects related to either a specific disease or transversal themes (e.g. palliative care or epidemiology), and target, pathway and immunology oriented inter-diseases sessions will be planned. The 48th Annual Congress of SIOP, the International Society of Paediatric Oncology, this year will take place in Europe: from 19 to 22 October 2019 in Dublin, Ireland. During four days of plenary sessions, guest lectures, committee/group sessions, “meet the expert”, paper sessions, and Young Investigators’ sessions almost all aspects of paediatric oncology, from basic science to clinical studies, will be discussed.
