Abstracts selected for presentation during the meeting (poster or oral) will be posted on the virtual meeting platform at 6 p.m. ET on January 7, 2022. Every effort will be made to reproduce the content of the abstracts as submitted, except in certain circumstances where changes may be made to comply with AACR style. Abstract titles and authors (no data) will be posted on the AACR website before the meeting begins.  

Poster presenters will be encouraged to participate in-person at the meeting but will not be required to do so if unable to travel to Lake Buena Vista.  Poster presenters participating in-person will be required to present both a physical poster and a short video for the virtual meeting platform.  Poster presenters unable to travel to Lake Buena Vista will be required to submit the short video for the virtual meeting platform. The short videos and associated abstracts will be released at the start of the in-person meeting on the virtual platform. See a sample poster layout

For programs that include proffered talks selected from the abstract submissions, instructions will be sent to the ABSTRACT PRESENTERS with the date, time, and format for those presentations. All short talk presenters from the U.S. will be required to participate in-person. Those from outside the U.S. who are selected to present short talks will be encouraged to participate in-person, but may present remotely if unable to travel to Lake Buena Vista.
