Eastern Cooperative Oncology Group
（重定向自ECOG）
The Eastern Cooperative Oncology Group (ECOG) began in 1955 as one of the first publicly funded cooperative groups to perform multi-center clinical trials for cancer research. A cooperative group in oncology constitutes a large network of private and public medical institutions that work toward developing various protocols for effective cancer treatments. Institutional members include universities, medical centers, governments, and other cooperative groups. These institutions share the common goal of ultimately curing cancer. Research results are often provided to the worldwide medical community through scientific publications, but ECOG also works closely with the pharmaceutical industry to test potential cancer drugs.
