ALEXANDRIA, Va. – Cancer experts from around the world will gather to share the latest clinical cancer research impacting patient care at the 55th Annual Meeting of the American Society of Clinical Oncology (ASCO). Advances in targeted therapies for pancreatic, prostate, and pediatric cancers, as well as new approaches to overcoming limited access to cancer care are among the topics that will be highlighted in the meeting’s official Press Program.  

The 2019 ASCO Annual Meeting, taking place May 31-June 4 in Chicago, will bring together more than 32,000 oncology professionals from across the globe. The theme of this year’s conference is Caring for Every Patient, Learning From Every Patient. 

More than 2,400 abstracts were accepted for presentation at the Annual Meeting, and more than 3,200 additional abstracts were accepted for online publication. The vast majority of these abstracts will be publicly posted on on Wednesday, May 15, at 5:00 p.m. ET. Late-Breaking Abstracts (LBAs), including Plenary abstracts, will be released on site throughout the Annual Meeting and highlighted in daily press briefings.
