Accepted Abstracts

My abstract was accepted, do I have to register for the meeting? 

Yes, the presenting author must register for the Annual Meeting to present an abstract. Submitting an abstract does not register you for the meeting.

Is registration free because my abstract was accepted? 

Unfortunately, SITC does not offer free registration to abstract presenters.

My abstract has been accepted, how do I confirm my participation? 

SITC is monitoring the COVID-19 situation and plans to announce any decisions in mid-summer. More information about requirements for accepted abstract presentations is forthcoming.

After regular and late-breaking abstracts are reviewed and selected, abstract submitters are sent an email notification stating whether the abstract was accepted, and, if so, what type of abstract presentation it was accepted as. Within the notification, the abstract submitter will also be asked to accept or decline participation in SITC 2021. If SITC does not receive a response by the stated deadline, SITC will assume you agree to present and will include your abstract.

When will I find out when I am presenting? 

SITC is monitoring the COVID-19 situation and plans to announce any decisions in mid-summer. More information about requirements for accepted abstract presentations is forthcoming.

Both oral and poster abstract presenters will be informed of their presentation details in their notification email.

I was accepted for an oral abstract presentation, can I present my abstract as a poster as well? 

In addition to oral abstract presentations, oral presenters are invited to present their abstract as an ePoster as well. ePosters can be uploaded by the presenting author in the Speaker Management System. 

What is my abstract number? Is this different than the abstract ID number? 

The abstract number refers to the number assigned to the abstract by SITC. The abstract number is the number that is made public for your abstract. The abstract ID is the number assigned by the submission site when you submit your abstract. This number is used for administrative purposes and is not made public.

What does the abstract number mean? 

The abstract number determines where your abstract will be listed in all publications including the Journal for ImmunoTherapy of Cancer (JITC) Supplement, and on the SITC 2021 website and meeting app. For abstracts selected for poster presentation, it also determines where your poster will be located in the Poster Hall.

How is the abstract number assigned? 

The abstract number is determined by the category selected when the abstract is submitted and the last name of the submitter.

Can I change my abstract number? 

Once assigned, abstract numbers cannot be changed.

How can I view my submitted abstract? 

You may view your submitted abstract by logging into the abstract submission system and clicking on 'My Abstracts'.

When is the deadline to withdraw my abstract? 

The deadline for regular abstract withdrawal is Sept. 2, 2021. The deadline for late-breaking abstract withdrawal is Sept. 24, 2021. If you would like to withdraw your abstract between the submission deadline and this date, you must submit your request in writing to education@sitcancer.org.
