Grid-enabled sentinel network for cancer surveillance

Recent developments of grid services for secured distributed data management open new perspectives for disease surveillance. In this paper, we report on our initiative to develop a surveillance network for breast cancer in the Auvergne region. The network gathers cytopathology laboratories, structures in charge of cancer screening and institutes in charge of cancer epidemiology. Data stored in cytopathology laboratories are queried through the grid for the purpose of second diagnosis and to produce statistical indicators. The paper describes the network goal and design and discusses specific issues related to patient identification and security.
