[Tumor frequency in autopsy cases. I: frequency, age and sex distribution, primary localization (author's transl)].

The analysis is based on the catalogue of neoplasms notifiable in the German Democratic Republic (ICD-Code Nrs. 140-209, 210.2, 211.3, 211.9, 225, 226.2, 226.3, 253.0, 253.2, 702, 757.2). At the Medical Academy of Erfurt 22,155 autopsies (12,212 males, 9,943 females) of adults (15 years and upwards) were registrated in the period from 1950 to 1966. 7,533 malignant tumours (34.2%) were observed. 99 cases were eliminated because of an unknown localization of the primary tumour. The remaining 7,442 cases (33.6%) are distributed among 3,987 males (326% of males) and 3,455 females (34,7% of females). The frequency difference based on the autopsy frequency of males or females, is distinct. Malignant epithelial tumours were observed in 5,559 cases (253% of autopsies; 752% of malignant tumours); 2,945 males and 2,654 females. The frequency difference also is distinct. Malignant nonepithelial tumours were observed in 1,843 cases (83% of autopsies, 24.8% of malignant tumours); 1,042 males and 801 females. There is no difference in frequency. Age and sex distribution as well as the relative curve of age distribution (Dormanns 1933) are presented for all the tumours, epithelial and nonepithelial neoplasms. The frequency of primary tumour-localization is reported for males and females, too. In males the frequency is in the following order: lung, stomach, hemopoetic-lymphatic system, colon and central nervous system; in females: sex organs (without mamma), stomach, colon, hemopoetic-lymphatic system and central nervous system.
