Please find below frequently asked questions related to the changes of the 2nd SIOP Europe Annual Meeting. This FAQ will be updated regularly as we receive additional questions.

What are the new dates of the 2nd SIOP Europe Annual Meeting?

The 2nd SIOP Europe Annual Meeting will take place virtually on 28 - 30 April 2021.  

Why was the 2nd SIOP Europe Annual Meeting format changed to a VIRTUAL?

The 2nd SIOP Europe Annual Meeting format changed from physical meeting to VIRTUAL due to the risks associated with the COVID-19 pandemic. The health and safety of all Annual Meeting attendees and the patients/communities they serve are SIOP Europe’s main priorities. This difficult decision to change the format of the Annual Meeting was made following regular updates and information received from the World Health Organisation, local health advisory authorities together with feedback from members of the peadiatric oncology community. 

A Virtual Meeting: What does it mean?

"Virtual” means that all plenary sessions, scientific sessions, operational meetings and the industry exhibition will be featured online.

Delegates will have access to an online platform for the Virtual Meeting and a scheduled programme will be provided.  Most plenary sessions will be streamed ‘live’ but some will be pre-recorded. All sessions will be recorded and available for viewing ‘on demand’ until 25 June 2021. 

The SIOP Europe Virtual Annual Meeting will provide a distinct opportunity for participants to share their knowledge, collaborate on cutting-edge research and debate the outcomes of the high quality clinical and basic research carried out in Europe, as well as provide mentoring and training for young doctors and fellows.

Do I need a special connection, tool, or software to attend a Virtual Congress?
