Cancer Cooperative Groups design and conduct clinical trials exploring new cancer treatments,
methods of cancer prevention and early detection, and quality-of-life and rehabilitation issues.
The National Cancer Institute-sponsored Clinical Trials Cooperative Group Program, created in 1955,
includes several research networks, called cooperative groups, that conduct cancer clinical research
primarily under the sponsorship of the NCI. Cooperative groups have a strong track record of designing and
completing trials that have diminished the impact of cancer in many ways.
The list below includes all cancer cooperative groups in the NCI-sponsored program. Several
of the cooperative groups are in the midst of mergers and consolidations. The
News and Information section contains more information about the
changes ongoing in the cooperative groups which serve adults with cancer or at
risk of developing the disease. In the list below, merging groups are presented
together under their proposed or chosen new names. Please visit individual websites
to learn more about the accomplishments and ongoing clinical research of each of
the cooperative groups.
