[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)]. / Maligne Tumoren von Lunge und Bronchien bei Kindern und Jugendlichen. 2. Mitteilung: Analyse von 66 Fällen aus dem Nationalen Krebsregister der DDR (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.

[Malignant tumors of lungs and bronchi in children and youths. 1. Compilation of 175 cases from the literature]. / Maligne Tumoren von Lunge und Bronchien bei Kindern und Jugendlichen. 1. Mitteilung: Zusammenstellung von 175 Fällen aus der Literatur.

The authors collected data of 175 malignant and semimalignant tumors in children and adolescents. 74.3 per cent of all reported cases were epithelial tumors (44.0 per cent bronchial adenomas and 30.3 per cent carcinomas), 15.4 per cent of embryonal and 10.3 per cent of mesenchymal origin. All age groups were affected. In children under one year of age embryonal tumors prevailed, in preschool age carcinomas and embryonal tumors dominated while in schoolchildren more often bronchial adenomas and carcinomas were found. All these tumors are very unusual in the pediatric age group. Therefore the right diagnosis is often missed for a longer time.
