[Malignant tumors of the lung and bronchi in children and adolescents. 2. Analysis of 66 cases of the East German National Cancer Registry (1961-1985)].

In the National Cancer Registry of the GDR from 1961 to 1985 only 66 cases malignant (and semimalignant) tumors of the bronchi and lung in patients under 20 years of age were collected. These amounted to 0,037 per cent of all tumor cases of this localization. These tumors affected 37 boys and 29 girls. Tumors of mesenchymal origin prevailed (32 cases = 48.4 per cent) in comparison to those of epithelial (37.8 per cent) and embryonal origin (10.7 per cent). Among these cases were 10 bronchial carcinomas and 10 bronchial adenomas. 51.5 per cent of all patients died in the clinic. Less than half of the patients were due to adequate therapy discharged free of any tumor. Data about the late prognosis of these patients were not available.
