Welcome to the 58th Annual SIOP Congress, taking place in San Antonio, USA, from 15–18 September 2026! We look forward to four lively days of cutting-edge science, clear-sighted discussion, and productive work with colleagues from across the globe.
San Antonio, with its strong clinical and research community, provides an excellent environment for a congress that is forward-looking and impactful. Our Scientific Committee, working closely with the Local Organizing Committee, is putting together a programme built on scientific excellence, practical relevance and global reach.
Being a global multidisciplinary society, SIOP wants to connect researchers (fundamental as well as clinical) and clinicians, to connect the different professional disciplines and to connect the different parts of the world. You can expect rigorous sessions led by world-class experts, data-driven insights, and debates that challenge us to raise standards in every region. Our goal is simple and ambitious: to accelerate change and deliver tangible improvements for children everywhere.
