Once an abstract has been made public, you may distribute a press release. SIO reserves the right to distribute press releases in advance of the release date above regarding submitted and accepted notable research.

Resubmission Policy for SIO Abstracts to Other Meetings

The process by which SIO Abstracts are submitted to other meetings is governed by the other meeting organizer. SIO does not prohibit the submission of previously accepted abstracts to other meetings however, it is strongly encouraged that submitting authors notify meeting organizers of their previous acceptance/presentation to SIO meetings.

Withdrawals and No-Show Policy

Acceptance of an abstract for the following: Scientific Oral Abstract Presentations or Discovery Theater Presentations obligates the author to attend the 2024 Annual Scientific Meeting to present in person. If circumstances prevent the presenting author’s attendance, the author must arrange for the work to be presented by a substitute, preferably a co-author. If you wish to withdraw your abstract, you must submit your request in writing by Tuesday, 2 January 2024 to education@sio-central.org and include the abstract title and presenting author’s name.

On rare occasions, selected presenters fail to show up without notifying the Society of Interventional Oncology. When presenters do not attend as planned, the efforts of the Scientific Chair and Program Committee to provide a quality program are diminished, significant costs are imposed, and the audience is unnecessarily disappointed. SIO staff will audit abstracts for no-shows. Failure to comply with these policies may result in ineligibility for participation in future SIO meetings.
