Late-Breaking Abstract Information and Eligibility Late-breaking abstract submission is solely for abstracts with late-breaking data and not for abstracts submitted “late.” The late-breaking abstract deadline is not intended to be an extension of the general submission deadline. Late-breaking abstracts highlight novel and practice-changing studies, and only apply to data that would have not otherwise have been presented as an abstract at the 35th Anniversary Annual Meeting. Examples of acceptable late-breaking abstracts include the following (in each case, results were not available or significant by the regular abstract submission deadline): ? Results of a practice-changing prospective Phase III clinical trial ? Phase II study showing anti-tumor activity in a novel context ? An early clinical trial with novel proof-of-principle data ? Demonstration of novel cancer biology with therapeutic implications
