On March 4, 2022, AACR President David A. Tuveson, MD, PhD, FAACR, and AACR Chief Executive Officer Margaret Foti, PhD, MD (hc), issued the following statement: “As the world’s first and largest organization dedicated to accelerating advances against cancer, the AACR (American Association for Cancer Research) and its more than 50,000 members from around the world stand in solidarity with the citizens of Ukraine during the Russian attack on their country. Ukrainian cancer patients of all ages are vulnerable, especially at this time while their care is interrupted by acts of war, criminal attacks on medical facilities, and dwindling food and supplies. As a global cancer research organization, the AACR is committed to supporting its members in Ukraine and the entire Ukrainian cancer community. We call for the immediate protection and safe passage to other countries of all cancer patients and of the cancer researchers and medical providers who are needed to maintain the momentum of cancer discovery and care."
