“Considering the uncertainties about the COVID situation worldwide later in the year and the anticipated travel restrictions affecting those working in hospitals and universities, the SIOP Board has made the decision to hold SIOP 2021 in a completely on-line format.

We will build on the success of this format from the 2020 congress.

The Scientific Committee is working hard to offer a rich programme with many live sessions. We look forward to seeing your research and progress in outcomes and care.”

Kathy Pritchard-Jones, SIOP President
