Dear friends and colleagues,

Following the latest COVID-19 developments, we would like to address any concerns regarding the upcoming SIOP Congress in October.

At this stage, the Coronavirus epidemic doesn’t stop the preparations for SIOP 2020.

However, we are taking the current COVID-19 situation very seriously and we will continue to closely monitor the situation and issue regular updates. The safety of all participants, staff and partners are very important to us.

We are actively taking all the recommended measures for the SIOP Annual Congress in accordance to the COVID-19 guidance provided by the World Health Organization (WHO).

Our members and Annual Meeting attendees are encouraged to regularly check the information made available by WHO and review your own government travel advice.


Please find below answers to most frequently asked questions regarding the COVID-19 developments:

Yes. There are currently no plans to postpone or cancel the Annual Congress (14- 17 October 2020, Ottawa, Canada).

However, we are paying close attention to new developments and guidance from the World Health Organization (WHO) and the European Centre for Disease Prevention and Control (ECDC).

We will keep you updated if any new information is available.

In recognition of the increasing pressures on clinical services due to the COVID-19 pandemic, we have decided to extend the SIOP 2020 abstract submission deadline until April 16 (12:00 midnight PST). Abstract acceptance notification will be in late June.

As challenging as the current situation may be, the COVID-19 outbreak emphasises the importance of advancing science, for which international collaboration is key!

Your findings and analysis directly impact the research and treatment of all our patients, no matter where they are in the world.

Note: Abstract submission is free of charge and does not require registration to the congress or any other binding commitments. 

Registration is now open and the early bird deadline is July 29.

Since the situation can be changing within hours at the moment, we cannot advise you what will happen until the summer months. As mentioned before, we continue to closely monitor the situation and issue regular updates to our members and community.

Congress Registration

SIOP is not planning to change the meeting dates or cancel the congress at this point in time. Depending on the global situation closer to the actual congress date, a final decision on hosting the meeting and respectively the registration policy will be taken and communicated to all registrants in due time.

Travel & Accommodation

Please keep flexibility and cancellation policies in mind when booking flights, accommodation or making any other travel arrangements for the annual congress.

Since cancellation terms depend on individual circumstances, please refer directly to your contractual partner.

As a general rule, the standard cancellation policy of your place of your travel provider and accommodation will apply. For detailed information, please contact your provider and, if required, your travel insurance company.

If you have any questions, please use the contact form here.

Please select the most relevant subject for your query and a member of our team will get back to you as soon as possible.

In addition, our president Prof Kathy Pritchard-Jones was so kind to share the
Children’s Cancer and Leukaemia Group (CCLG) Coronavirus advise for children and young people on active cancer treatment

Despite being UK specific, we believe this is a great resource and are hoping that other countries are doing something similar in other languages.


Our thoughts and wishes go out to affected patients and healthcare staff at this difficult time!

We will continue to closely monitor the situation and issue regular updates.

Take care of yourself, your loved ones and patients of course!
