[Cancer register problems--modified reporting law model for the improvement of data protection].

The author suggests creating a "Reporting Law Model with Peripheral Part Anonymisation" that preserves the advantages of the reporting law model which are internationally recognised in respect of reliability of registration, on the one hand, while on the other hand the general and individual requirements of sufficient protection of sensitive data are also taken care of. This is achieved by separating the personal data from the factual data at the reporting office level. These data are transmitted separately to the registration offices and their confidential files. It is nevertheless possible to detect any double or multiple reporting and to perform fault finding in respect of personal data. It is also possible to add further data to any patient's case history. This cancer registration model can always cope with the required descriptive and analytical epidemiological tasks that are expected of it. It can be arranged to cover a wide area in a continuous manner without loss of time and without considerable expenditure. Documentation work to be performed by the reporting offices is minimised.
