[A model for the valuation of mass attendance and attendance duration of patients with malignant neoplasms (author's transpl)].

By means of a combination of two methods known in demography - life table and estimates for intercensal years - probabilities of prevalence of cancer patients and duration of disease from onset to death are calculated. Starting-points are the incidence know by cancerregistration and death certificates. The results of the model are compared with the results of a special point prevalence counting. Both methods gave about the same results.
