It's a pilot project sponsored by the National Cancer Institute (NCI) for the support of a national network of physicians to participate in NCI-sponsored Phase III cancer treatment trials. Cooperative Group sites located within the United States and Canada are currently eligible for participation in the CTSU. The CTSU has opened its protocol menu to qualified medical, radiation, and surgical oncologists and hematologists who are not Cooperative Group members. The new policy allows cancer patients anywhere in the USA to participate more easily in advanced (Phase III) treatment trials.
