The Eastern Cooperative Oncology Group (ECOG) was established in 1955 as one of the first cooperative groups launched to perform multi-center cancer clinical trials. A cooperative group is a large network of researchers, physicians, and health care professionals at public and private institutions across the country who are members of the group. Funded primarily by the National Cancer Institute (NCI), ECOG has evolved from a five member consortium of institutions on the East Coast to one of the largest clinical cancer research organizations in the U.S. with almost 6000 physicians, nurses, pharmacists, statisticians, and clinical research associates (CRAs) from the U.S., Canada, and South Africa. Institutional members include universities, medical centers, Community Clinical Oncology Programs (CCOPs), and Cooperative Group Outreach Programs (CGOPs). These institutions work toward the common goal of controlling, effectively treating, and ultimately curing cancer. Research results are provided to the world-wide medical community through scientific publications and professional meetings.
Currently, ECOG has more than 90 active clinical trials in all types of adult malignancies. Annual accrual is 6,000 patients, with more than 20,000 patients in follow-up.
