Late breaking abstracts

General information

Abstract submission is open from 12-19 October 2026.

Late-breaking abstracts describe the latest advances that will change our daily clinical practice. They should highlight novel and practice-changing studies. Focus is placed on capturing abstracts with ground-breaking and unique data that would not otherwise have been presented at the Symposium.

Examples of suitable late-breaking abstracts might include the results of a practice-changing prospective Phase III clinical trial; a Phase II study showing anti-tumor activity in a novel context; an early clinical trial with novel proof-of-principle data, or the demonstration of novel cancer biology with therapeutic implications – in each case the results should not have been fully available by the regular abstract submission deadline.
