[Tumour frequency in autopsy cases. IV. The malignant tumours of the kidney (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 performed in the period from 1950 to 1966. Among them 186 malignant tumours of the kidney (177 carcinomas, 9 sarcomas) were observed. The cases are distributed among 126 males (1% of males) and 60 females (0.6% of females). The frequency difference is not distinct. Age and sex distribution, frequency and localization of metastases as well as the histologic classification are presented.
