Late-Breaking Abstract Guidelines

Placeholder Deadline: Monday, February 22, 2027, at 11:59pm ET

Final Deadline: Friday, April 9, 2027, at 5:00pm ET



SNO recognizes that some rapidly advancing investigations may include results that will not be available at the time of February 22, 2027, abstract submission deadline. For this reason, SNO will allow authors to submit their late-breaking clinical trial research for consideration for the 2027 EANO-SNO Joint Meeting on Pediatric Neuro-Oncology.


Late-breaking submissions must adhere to guidelines below and a placeholder abstract must be submitted by the initial February 22 submission deadline. Late-breaking abstracts will not be accepted if a placeholder abstract is not submitted by February 22, 2027.


Abstracts that are not clinical trials following interim or final analysis may not be submitted as Late Breaking abstracts and may be rejected.


Please note that only a limited number of abstracts from this late-breaking category will be selected for oral presentation at the meeting. Authors should note the following important information before submitting a late-breaking abstract:

  • Late-breaking abstracts accepted for presentation will not be included in the regular abstract supplement to Neuro-Oncology Pediatrics and will be published electronically on the day of presentation.
  • This category is not intended to offer a second deadline for regular abstract submissions.
  • Late breaking


For an abstract to be considered for Late-Breaking Abstract status, the submitting author must:

  • Submit the abstract using the late breaking abstract link in the submission site.
  • Submit a clinical trial abstract, including the objectives and methods but excluding the results and conclusions of the research, by the submission deadline of Monday, February 22, 2027. Include any information that supports the potential for late-breaking impact, and the date of planned analysis for the abstract.
  • Submit a final late-breaking abstract with updated data by Friday, April 9, 2027. If an updated abstract is not submitted by that date, the abstract will be automatically rejected.
