Czech oncologists have a unique opportunity to study population-based cancer data in National Cancer Registry (NCR) with more than 1.3 million records reported since 1977. The quality of collected data as well as data management of the registry are becoming of growing importance. Many actual problems are intensively discussed, namely paper data sheets gathered without any support of hospital information systems and too universal data model ignoring some diagnostically specific items. User-oriented attributes are discussed as well, because the system appears to be rigid without adequate information feedback for final users. Thus, the system must be technologically updated and equipped by on-line tools with hospital-based information background. The physicians, oncologists, must reach the position of experts approving the final records in automated system with subsequent opportunity to view the database and to analyze the content on their own. Assumptions and rules for the development of such system are summarized here in the context of current operation of NCR. To enhance the communication, the electronic on-line version of NCR record was developed and implemented in server of Masaryk University: www.svod.cz/nor. Through this educational template, the experts can study the structure and data management rules of NCR.
