A Total 655 cases of malignant tumors in childhood under 15 years of age who admitted to general
hospitals in Chonnam area during the 10-year period from January 1976 to December 1985 were
analysed.
The frequency of malignant tumors among total pediatric inpatients was 2.64% (1.48〜4.52%) with
tendency to increse year after year. In 1980, the number of population under 15 years of age was 1,
431,683, but decreased gradually to 1,268,039 in 1984. However, children’s cancer patients actually
increased annually.
In general male are affected more often than female with sex ratio (M/F) of 1.48:1.
The most common malignancy was leukemia (43.05%). Out of 282 cases of leukemia, 174 cases (61.
70%) were acute lymphocytic, 78 cases (27.66%) were acute myelogenous, 12 cases (4.26%) were
chronic myelogenous, and 18 cases (6.38%) were unclassified leukemia. The next common malignancy
in childhood was brain tumor (16.03%), followed by lymphoma (9.16%), Wilms' tumor (6.11%),
neuroblastoma and gonadal and germ cell tumor (4.43%), bone tumor (4.12%), retinoblastoma (3.66%),
liver tumor (3.51%), and soft tissue tumor (3.36%) in order. Retinoblastoma and liver tumor were
relatively prevalent compared to U.S.A. and European countries.
About 38.32% of malignant tumors were found under 5 years of age. Wilms’ tumor, neuroblastoma,
gonadal and germ cell tumor, retinoblastoma, and liver tumor were seen mostly before the age of 5
to 6 years, while brain tumor, lymphoma, and bone tumor have the tendency to increase the incidence
over the age of 6 years.
There were significant geographical differences in the incidence of malignancy per 100 thousand
population under 15 years of age according to area to area. Overall incidence rate of childhood cancer
was 5.17/105 population. Geographically, in Yeochon, Yeosu, Kwangju, Hwasun, Muan, and Gogseong
were 8.85, 7.00, 6.95, 6.34, 5.98, and 5.58 per 100 thousand population respectively. Such high frequency
rates in Yeochon and Yeosu were statistically significant (p<0.01).
It appears that above results may offer some useful informations on the frequency rates of
childhood malignancies in Chonnam area. |
