PRESIDENT’S LETTER DEAR READERS Dana-Farber Cancer Institute was founded by a man at odds with the medical orthodoxy of his time, which held that there were limitations on what cancer medicine could accomplish. Seventy-five years later, that dissatisfaction with the status quo remains part of the organization’s genome. In Dr. Sidney Farber’s era, the prevailing wisdom was that drugs capable of killing cancer cells would be too toxic – too harmful – to be useful. Farber’s success in using chemotherapy to produce the first remissions of leukemia in children showed those concerns to be unfounded (although it took the medical establishment several years to fully embrace this approach). Farber summarized his philosophy this way: “I have never accepted the incurability of cancer. And I have remained hopeful, not because of wishful thinking – that’s not progress – but because of the factual evidence of progress.” It’s hard to overstate how radical that statement was for its era, a time when pediatric leukemia was nearly always fatal, when survival periods for most cancers were a fraction of what they are today, when many hospi- “As we mark the Institute’s tals didn’t have cancer wards because there was so little that could 75th anniversary this year, we be done for patients. are the heirs not only of decades As we mark the Institute’s 75th anniversary this year, we are the heirs not only of decades of advances against cancer but also of a of advances against cancer but way of thinking about cancer – not as a disease to be endured but also of a way of thinking about one to be defied and eventually defeated.

We hope this gift will inspire others to also support the tremendous work happening every day in Dana-Farber’s labs and clinics.” The $40 million grant builds upon ongoing work and will deepen and expand approaches for addressing the most complex challenges in myeloma research and improving patient care. Specifically, the grant will: • Renew support for preclinical experiments to identify novel targets and develop new medicines and immune-based therapies for patients; • Fund clinical research designed to test novel myeloma therapies, alone and in combination with standard and experimental treatments, to improve Annamaria Gulla, MD (right), and Megan Johnstone in the patient outcomes; and, Multiple Myeloma lab. • Support the co-location of myeloma labs at In early 2022, Paula and Rodger Riney of St. Louis, Dana-Farber to facilitate greater cohesion Mo, through the Paula and Rodger Riney Foundation, and collaboration among members of the announced a $40 million grant to support multiple research team. myeloma research at Dana-Farber, representing the largest single award supporting multiple myeloma The Paula and Rodger Riney Foundation has been research in the Institute’s history. a strong supporter of Dana-Farber and with this grant “The Riney Family are generous and stalwart sup- has cumulatively donated nearly $60 million to the porters, and through this grant and their previous Institute.

AROUND THE INSTITUTE 75 Years of Advancing Cancer Care and Treatment Dana-Farber's story begins in 1947 with the first successful treatment of blood cancers by Sidney Farber, MD, earning him the reputation as the “father of modern chemotherapy.” Now, 75 years later, the combination of clinical treatment, bench-to-bedside research, and high-quality holistic patient care has made the Institute a leader in life-changing breakthroughs.
