Please follow the instructions listed on this website step-by-step:

  • Abstracts submitted via fax will not be accepted.
  • Submission of an abstract acknowledges your acceptance for the abstract to be published in the official meeting publications.
  • Presenting authors of abstracts must be registered participants. Registration must be received by the Secretariat by the Early Registration Deadline: July 21, 2014 to ensure inclusion of the abstract in the meeting publications and in order to be scheduled for presentation.
  • The content of the abstract should not have been previously published or presented at national or international meetings prior to 2014.
  • Abstracts must be submitted and presented in clear English with correct grammar and spelling of a quality suitable for publication. If you need help, you are welcome to contact your Continental President of SIOP listed below, who will be able to assist you with the English of your abstract. For assistance, abstract must be sent at least one week prior the deadline.  ​Please note that abstracts submitted with a low level of English will not be considered for presentation.
  • Abstract text should be 300 words or less. The word count excludes the abstract title, author names and affiliations.
  • Abstracts must be received by the announced deadline. Abstracts received after the deadline will not be considered.
  • Abstracts stating "data will be discussed in the presentation" will NOT be accepted.
  • Case reports and small institutional series of limited added scientific value are not encouraged.  Prospective multicentric studies as well as presentation of large translational projects are considered as major quality criteria

The Scientific Committee will determine whether the abstract will be accepted and, if yes, will determine whether it will be selected as an oral presentation, a poster presentation, or a journal publication, with consideration given to the author's preference.​

The presenting author is required to ensure that all co-authors are aware of the content of the abstract before submission to the Secretariat.

SIOP will publish all accepted abstracts online (open access) for a period of at least 5 years. The abstract published online will include the e-mail address of the presenting author. As a condition of submission, SIOP requires you to agree to such publication and to surrender any copyright over the abstract as submitted to SIOP.
