title: [Epidemiological survey of childhood leukemia].
abstract: This paper reports epidemiological data of childhood leukemia in the 14 years 1973-1986 in Qidong county, Jiangsu province. Mortality of childhood leukemia was 1.74 per 10 million, taking first place among various malignant tumors of children. The annual mortality distribution of this disease and the age and season at death showed no significant difference, But finer age grouping of death rates revealed remarkable difference. Thus, in 0-4 age-group the mortality was 2.95 per 10 million higher than the remainder. Childhood leukemia mortality by space-Time Clusters analysis showed the significance of difference lobe P greater than 0.05, suggesting that childhood leukemia mortality in space and time clusters were random.
