This project is distinct in that it includes both an extensive effort to evaluate the current state of the art as well as the development of new methods and software tools to fill any identified gaps. The proposal brings together a team of researchers with an established track record, proven collaborative efforts and strong links to the Pennsylvania Cancer Registry, the Appalachia Cancer Network and Pennsylvania State public health agencies. This is one of two related applications being proposed to a PEP. While each application is independent and has sufficient merit to stand upon its own, the two proposals share the same link to the Pennsylvania State public health agencies, developed as part of an ongoing NCI-funded research project on the visualization and spatial analysis of cancer data. The current proposed project thus leverages the ongoing research, but does not duplicate it in the sense that it is focused on the specific needs of Comprehensive Cancer Control programs, concerns itself solely with prostate cancer (data and research questions), and addresses a much more comprehensive set of spatial data analysis methodologies.
