We have adapted a visual information display system to our head and neck cancer database containing over 150,000 datapoints on 5000 deindentified patients. This data visualization tool facilitates real time interactive database exploration with the intent of detecting subtle relationships, which may generate new hypotheses for further investigation. The interactive characteristics of the system allow dynamic access to individual records and concurrently selected cohorts, for in-depth study of patient characteristics, treatment strategies, and outcomes.
