The year 2020 brought many changes to SIOP.  Some were anticipated developments for our Society, others were forced upon us as the COVID-19 pandemic erupted across the world.  The SIOP Board of Directors and the SIOP members have been very active in responding to these challenges. The 2020 Annual Report summarises the huge efforts undertaken by our Committees, Working Groups and the wider membership to advance the cause of children and adolescents with cancer worldwide.
