[Epidemiology of primary tumors of the central nervous system in children and adolescents. A population-based study].

The incidence of primary CNS tumours in children and adolescents (0-20 years of age) was investigated for the time period 1970-1989 using the records of the East German National Cancer Registry. 2906 such tumors were registered. 93.

Epidemiologic data on meningiomas in East Germany 1961-1986: incidence, localization, age and sex distribution.

From 1961 to 1986, 8119 new cases of meningioma were reported to the National Cancer Register of East Germany (former German Democratic Republic) with an average population of 16.9 million. The crude annual incidence was 1.

On the background of differences in survival of female breast cancer patients in the German Democratic Republic and the Estonian SSR.

The aim of this study was to describe the age-specific survival patterns and to analyse the differences between the survival rates of female breast cancer patients in the German Democratic Republic in 1976-1977 and the Estonian SSR in 1968-1981. The estimated 5-year relative survival rate (RSR) was 64.1% in the GDR and 55.

A mortality study of a cohort of slate quarry workers in the German Democratic Republic.

Following reports from other countries indicating an excess risk of lung cancer among silicotics, a historical cohort of workers employed for at least one year at a company in charge of slate extraction and processing during the period 1953-1985 in the German Democratic Republic has been constructed and followed up for mortality from 1970 to 1985. The results of the study show a mortality excess for infectious and respiratory diseases. The overall lung cancer mortality is not in excess but shows a tendency to increase with time since first exposure.

[Lung cancer in the DDR with special reference to histological types and cigarette consumption].

By an analysis in detail of incidences of lung cancer of the years 1971 to 1984 and of the data of consumption of cigarettes per head in GDR during the years 1960 to 1984 we discussed the further trends of morbidity and mortality in lung cancer in our country. We pointed out: 1. From 1972 to 1985 the mortality of lung cancer in males dropped from 6,023 per year to 5,213, while that of females increased from 698 to 959.
