Abstract
|
|
|
1,095 cases of leukemia and allied conditions of Koreans were analysed. The cases
were diagnosed by the authors by means of peripheral blood and bone marrow
examinations at the Department of Laboratory Medicine, Seoul National University
Hospital during the last 22 years from 1957 to 1978.
The results of the study are summarized as follows:
1. The number of leukemia patients has markedly increased from 51 cased in 1957∼
1959 to 221 cases in 1975∼1977. and it was mainly due to an increase of the acute
forms and childhood leukemias. The relative frequency of chronic leukemias are
remarkably decreased in recent years.
2. Male to female sex ratio is 1.9 : 1 in over-all leukemia cases, however it is 2.2 : 1
in the age group of 15∼29 years and 1.2 : 1 in the age group of 60 years and over.
The male to female ratio in acute lymphocytic leukemia and acute monocytic leukemia is
2.1 : 1, while it is 1.9 : 1 in acute myeloblastic leukemia and 1.3 : 1 in chronic
granulocytic leukemia.
3. The age incidence of leukemia is highest at the age group of 0∼14 years being
35.3% and decreases with the increase of age, i.e., 28.4% at 15∼29, 20.5% at 30∼44,
12.0% at 45∼59 and 3.9% in the age group of 60 years and over.
4. The frequency of the most prevalent types of leukemias are as follows: Acute
myeloblastic leukemia: 375 cases(34.2%) Acute lymphocytic leukemia: 320 cases(29.2%)
Chronic granulocytic leukemia: 163 cases (14.9%) Myelo-monocytic leukemia: 55
cases(5.0%).
5. The frequencies of relatively rare leukemic conditions in the total of 1,095 cases are
as follows: Lymphoma with leukemic manifestation in peripheral blood: 38 cases(3.5%)
multiple myeloma: 36 cases(3.3%) Erythremic myelosis and erythroleukemia: 29
cases(2.6%) monocytic leukemia: 25 cases(2.3%) Acute promyelocytic leukemia: 18
cases(1.6%) stem cell leukemia: 10 cases(0.9%) Chronic lymphocytic leukemia: 5
cases(0.5%).
6. Analyzing the seasonal distribution of initial case defections, the frequency of acute
leukemias are highest in the spring: the acute lymphocytic leukemia being most
prevalent in the spring, and the acute myeloblastic leukemia being most prevalent in
both the spring and summer.
