Description:This report contains data obtained through a program of leukemia surveillance established by the Center for Disease Control in 1966, in collaboration with certain state and local health departments. The program’s goals are 1) to maintain a registry of current data regarding leukemia incidence in participating areas and, 2) to support studies of oncogenesis by identifying individual cases or groups of cases in which special epidemiologic or laboratory studies may be desirable.
Data in this report are for the most part preliminary and are primarily intended for the information of persons concerned with studies of leukemia and related disorders.
Data are presented concerning 561 cases of leukemia diagnosed during 1970 in eight states and metropolitan areas participating in leukemia case surveillance.
The number of cases closely approximates expected incidence for these populations.
The 1970 data are compared with similar surveillance information for the preceding 4 years, 1966-1969. Case distributions by cell type, age, sex, and race followed expected patterns, and no marked trends by year or season of occurrence were seen in any area.
Occasional cases or case groups were reported with unusual epidemiologic or genetic features which may perhaps be related to etiology. Four such case groups are described in detail: 1) childhood leukemia in Middletown, Connecticut,
associated with a particular Roman Catholic parish and elementary school in the community, 2) acute leukemia in three teenagers attending one high school in Wantagh, New York, and diagnosed over a period of two school years, 3) four cases of chronic lymphocytic leukemia in members of a Georgia family including a man, his wife, and their son, and 4) eight cases of acute leukemia in Pleasant Grove, Utah, primarily affecting children and appearing largely in two clusters, one in 1967 and one in 1969.
