The AACR Annual Meeting is the touchstone of the cancer research community, each year bringing together thousands of cancer scientists, clinicians, other health care professionals, survivors, and patient advocates from around the world to discuss the latest research advances, connect with one another, and forge new collaborations. It was an immense privilege to witness so many scientific breakthroughs being shared at this year’s meeting.

We are truly grateful to Immediate Past President Patricia M. LoRusso, DO, PhD (hc), FAACR, and Program Committee Chairs Matthew G. Vander Heiden, MD, PhD, and AACR President Lillian L. Siu, MD, PhD, FAACR, for leading the development of such an incredible scientific program that showcased the amazing leaps being made across the continuum of cancer research. In addition, we thank the members of the program committees, the invited speakers, proffered abstract presenters, attendees, and dedicated AACR staff—all of whom made the AACR Annual Meeting 2025 a resounding success. Our shared commitment to driving progress against cancer helped make this meeting very productive and meaningful.
