ASCO Annual Meeting

The Annual Meeting brings together more than 30,000 oncology professionals from around the world to discuss state-of-the-art treatment modalities, new therapies, and ongoing controversies in the field.

ASCO’s primary concern is the health and safety of the global oncology community and the patients we serve. As public health safety measures related to COVID-19 extend, the ASCO Board has concluded that the Annual Meeting, scheduled for May 29-June 2 in Chicago, cannot occur in person as planned.  

Our mission is as important as ever. That is why we still intend to deliver the latest cancer science to the global community during the Annual Meeting timeframe using a virtual format that respects the contributions of the authors and the work of the Scientific Program Committee. In addition, abstracts will be published online and in the Journal of Clinical Oncology on our usual schedule. ASCO’s educational program will not take place during this timeframe, and we are exploring opportunities for the future. 

We understand that many members and Annual Meeting participants are wondering about our specific plans and hope you understand that we are currently working to resolve the large number of operational details this change in plans creates. 

Information on the format, dates, specific content, registration, refunds, and many other details will be available in the coming weeks and posted on

While we recognize that our face to face meeting in Chicago is ideal for sharing the best science and optimal approaches to patient care, we will unite as a global community to meet these unprecedented challenges and address the acute clinical care issues. 

May 29 ‐ June 2, 2020
