The NCI Community Cancer Centers Pilot Program (NCCCP), http://ncccp.cancer.gov, is a three-year pilot program to test the concept of a national network of community cancer centers to expand cancer research and deliver the latest, most advanced cancer care to a greater number of Americans in the communities in which they live.The pilot program is designed to encourage the collaboration of private-practice medical, surgical, and radiation oncologists, with close links to NCI research and to the network of 63 NCI-designated cancer Centers principally based at large research universities. NCI contracted with RTI International (ww.rti.org) to conduct a comprehensive evaluation of the NCCCP pilot program using multiple methodologies, including a survey of cancer patients receiving care at the pilot sites.
