Welcome to the ECOG-ACRIN Cancer Research Group website, the source of information about the cooperative group that was formed by the merger of the Eastern Cooperative Oncology Group (ECOG) and the American College of Radiology Imaging Network (ACRIN). We are excited to share news of our collaborative effort to design and conduct ground-breaking translational and clinical research.

The merger brought together the strengths and capabilities of two highly respected organizations. Since 1955, ECOG has performed practice-changing multicenter cancer clinical trials, working with more than 6000 physicians, nurses, pharmacists, statisticians, clinical research associates, and cancer research advocates from the United States and around the world. ACRIN, the premier imaging science program in the nation, complements ECOG’s research efforts with its expertise in early detection, imaging diagnosis, comparative-effectiveness research, and cost-effectiveness analysis. Now, as a single entity, we aim to achieve earlier cancer detection, more successful therapeutic intervention, higher rates of prevention, and better patient outcomes.

We look forward to sharing our research and partnering with you, as we reshape the future of patient care.
