Development of an Information System for Multicenter Epidemiologic Studies on Cancer

Cancer is caused by a variety of factors whose study requires a large amount of data. Compiling these data is an expensive and time-consuming task which can be carried out in a better way with the support of Information and Communication Technologies (ICT). However, most epidemiologic studies take place without this support of informatics or with basic tools that are developed by unqualified professionals. As a consequence, the integrity of the compiled data cannot be guaranteed, and the reliability of the studies is affected. This work presents an Information System (IS) for the development of multicenter epidemiologic studies on cancer which has been successfully applied to the execution of an epidemiologic study of colorectal cancer in Galicia, Spain.
