Despite the virtual format due to the coronavirus pandemic, UCSF once again had an impressive presence at this year's annual meeting of the AACR. The program has been separated into two parts, Week 1: April 10-15; Week 2: May 17-21, with the theme, “Discovery Science Driving Clinical Breakthroughs.” 

Dozens of the HDFCCC’s 400+ members were represented in abstracts accepted for presentation, and AACR provided investigators of all levels a chance to present and review research, confer with colleagues, and return with new ideas. The highlights from Week 1 are noted below in a list of abstracts, poster presentations, and activity on social media.
