Monthly Plenary Series

Today's Science Can't Wait

The ASCO Plenary Series is your chance to present breaking and relevant science year-round—this is the research that can't wait for the next meeting! The Scientific Review Committee is seeking abstracts that highlight high-impact research with practice-changing implications. 

Within two months of submission, accepted abstracts are presented in an online session that includes an invited discussant and live Question-and-Answer.
