The scientific impact and value of large, NCI-sponsored randomized phase III cancer chemoprevention trials

ConclusionBased on these criteria, the scientific impact of large phase III cancer chemoprevention trials was very high in absolute terms, and as good as or better than that of treatment trials after accounting for expenditure. For appropriate scientific questions, large chemoprevention trials provide a good scientific return on investment for federal funding agencies.Graphical abstract
