title: Acute non-lymphocytic leukemia is not a major type of childhood leukemia in Japan.
abstract: The distribution of acute leukemia according to type was examined in Japanese children by three surveys: (1) a review of bone marrow slides of 81 cases diagnosed as acute myelogenous leukemia between 1964 and 1976; (2) a prospective study of 97 cases observed since 1977, and (3) a study of 8108 cases registered with the Children's Cancer Registry of Japan from 1969 to 1984. The results indicate that the ratio of acute lymphocytic leukemia to non-lymphocytic leukemia in Japan is not different from that in other countries.
