Overview of U.S. National Cancer Institute (USNCI) Chemoprevention Research

Abstract

The National Cancer Institute's (NCI) chemoprevention plan employs a strategy of basic and epidemiologic studies, followed by a structured preclinical process to bring chemopreventive agents into clinical testing. The field of chemoprevention is progressing rapidly and has reached the point where a coordinated international approach for large-scale trials would be useful. At present, NCI is sponsoring nine large trials (over $1 million per year per trial); in addition, nine agents are in phase I or II clinical testing. A number of these agents should be ready soon for phase III testing. Resources required for large-scale trials compel greater attention to efficient trial designs, concept development and review, priority setting, management, budgeting, and collaboration.
