Abstract Policies and Procedures

Trials in Progress Policy

The Trials in Progress Category provides a unique opportunity for researchers to present ongoing trials at the SIO Annual Scientific Meeting.

Any phase (I, II, or III) trial that is ongoing, started enrolling patients or has completely enrolled, and has not yet reached prespecified endpoints for analysis may be considered for inclusion in the Trials in Progress submission category. Inclusion of results would be at the discretion of investigators. Presentation of preliminary results is not required for submission or acceptance.

All submissions will be reviewed for appropriateness by the SIO Annual Scientific Meeting Planning Committee. Accepted submissions will be notified of their presentation type.

Abstract Submissions for Trials in Progress should include Background, Methods, and Preliminary Results (optional, not required for acceptance):

Background:

Scientific background/rationale for the trial
Correlative studies of particular interest

Methods:

Trial design and statistical methods
Treatment or intervention planned
Major eligibility criteria
Clinical trial registration number (required)
Enrollment status

Preliminary Results (not required for acceptance):

Demographic, safety, and preliminary efficacy data (if appropriate for presentation).

What is not permissible in a Trials in Progress Abstract Submission:

Proprietary drug name
Information about pricing, fees, or reimbursement related to trial participation

Prior Presentation/Publication Abstract Submission Policy

SIO does not restrict the submission of abstracts that have been presented at prior meetings, or published prior to the 2025 Annual Scientific Meeting. If your submission has been presented prior to the 2025 Annual Scientific Meeting, please ensure you are adhering to the policies and procedures of the respective organization. SIO reserves the right to assign priority scoring to debut abstract presentations.

Embargo Policy and Information

All 2025 Annual Scientific Meeting Abstracts will be made public at the start of the conference, Thursday, 29 January 2025 at 7:00 am PST. 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.

Late-Breaking Abstracts

The SIO late-breaking abstract policy allows for the submission of late-breaking data and research which must contain information with results that were not yet discovered or available on the regular abstract submission deadline of 1 October 2024. Submissions for late-breaking abstracts will be announced following the regular abstract submission deadline on 14 January 2025.

Notification regarding late-breaking abstract’s acceptance or rejection will be sent to the submitter by 17 January 2025. Late-breaking abstracts should contain new information, which may include either:

Results which were not fully known or available on the regular submission deadline
Work that has been submitted for publication

Withdrawals and No-Show Policy

Acceptance of an abstract for any oral presentation obligates the author to attend the 2025 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, 7 January 2025 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.
