Methods

Currently, reliable data on the incidence of new cancer cases and survival rates are not yet available for all German states. Therefore, the German Centre for Cancer Registry Data (ZfKD) estimates national cancer incidence, prevalence and survival rates after assessing the completeness of the data recorded in the individual registries.

The methods employed at the ZfKD are described under the individual menu items. The basic principle is that the data are first checked for completeness of incidence and of vital status. Then, data from registries that meet certain predefined criteria are used to calculate the corresponding statistics for Germany.
