Abstract

PURPOSE: Of the cancers in childhood, leukemia is the most frequent one. For the desirable control of childhood leukemia, the basic data for the incidence has a great importance. The authors made a report about the incidence of leukemia in childhood, which analyzed the data from 126 cases in Kyongnam province, Korea, during 1991~1995. METHODS: The data were obtained from 126 new cases of childhood leukemia who had been living in the Kyongnam province and were diagnosed at the 26 university hospitals or general hospitals in the Kyongnam area and other cities from 1991 to 1995. RESULTS: The age-and-sex adjusted annual incidence rate per 100,000 population during 1991~1995 varied from 1.82 to 2.86, and cumulative annual incidence rate was 2.41 (male 2.26 and female 2.57 respectively). Male to female sex ratio was 1:1 in total cases. By the major types of childhood leukemia, the cases were composed of acute lymphocytic leukemia 70.6%, acute myelocytic leukemia 26.9% and chronic myelocytic leukemia 2.5%. The cumulative annual incidence rate per 100,000 population (crude rate) during 1991~1995 were 2.77 in Ulsan city, 2.62 in Chinju city and 2.34 in the whole area of Kyongnam province. CONCLUSION: It was concluded that the age-and-sex adjusted annual incidence rate per 100,000 of childhood in Kyongnam province was 2.41, which was lower than that in Pusan city in the same period. And, there was no significant difference of the cumulative annual incidence rate between Ulsan area and Chinju area in the same period.
