Meeting report: NCI think tanks in cancer biology.

Over the past year and a half, the Division of Cancer Biology of NCI has been assessing the state of cancer biology, with the goal of developing a research agenda for the near future that would accelerate progress in cancer research. Our goal was to identify emerging concepts and promising opportunities for investigation across nine scientific areas with unusual promise for rapid progress. A series of meetings called Think Tanks was convened, each involving a panel of 15-25 experts. In all, over 160 leaders in cancer research and related fields discussed the current state of science in their disciplines, projected its trajectory and recommended what NCI could or should do to facilitate progress. In addition to emphasizing the importance of continued support for investigator-initiated research, the Think Tanks permitted identification of a number of overarching themes. Critical among them was the need to support the development of integrative cancer biology and to encourage studies of the tumor microenvironment by establishing an infrastructure for interactive research. There was also consensus about the importance of comparative studies of normal and tumor states, and development of mechanisms for supporting collaborative, interdisciplinary research and training.
