[Cancer control (author's transl)]

Evaluation of Success Figures and Incidence Data: The survival rates of patients with esophageal, bronchail and mammary carcinoma were determined at fixed intervals as specific mean values, including the dependence of the standard deviation on the size of the treatment collectives (n = 50, 100, 1000). In addition to the statistical margin of error, the percentage frequency of bronchial and mammary carcinomas and also of leukemia in childhood was calculated in numerical and age groups. The application is demonstrated with examples.
