A cancer registration network based on computerised coded diagnoses has been tested in the Veneto region, north-east Italy, with the goal of estimating cancer incidence during 1987-89. The results of the pilot study based on a population of 1,449,513 (33.1% of the total population of the region) indicate that the computer-assisted system successfully ascertained 61.3% of the cases. The quality indices appear to be close to those from other cancer registries in Europe. The increasing availability of computerised coded information from hospitals, pathology departments and death certificates can provide an important contribution to cancer registration, thus reducing the amount of manual work and consequently allowing cancer registration on larger populations at reduced costs.
