  • Work closely with secretariat and ensure coordination with LOC



The SIOP Scientific Programme Advisory WG (former Scientific Programme Advisory Committee “SPAC”) has been founded in 2008 and consists of experts in specific fields of paediatric oncology.

The WG plays a vital role in creating the program for our annual congress. WG members suggest topics for Keynotes, Symposia, and Meet the Expert Sessions at the Congress and review and score submitted abstracts to help the Scientific Committee (SC) select abstracts for oral and poster presentation.


A Scientifi Programme Advisory WG member is expected to fulfill the following criteria:

  • WG members are expected to be internationally recognized experts in their field with appropriate clinical, translational and basic research accomplishments and publications
  • Show commitment and be in a position to sustain reliable communication (especially e-mail) with the SIOP Office and congress teams especially during the abstract review period which takes place early April of the congress year
  • Be an active member of the society


Benefits of being a WG member:

  • WG members are eligible to register for the annual meeting with the Early-Bird-Rate after the deadline
  • All WG members are invited to a networking reception during the annual meeting to hear feedback and enjoy a good company
