In several countries cancer is now the second most common causes of death in children over the age of one year. And it has recently become apparent that there is as much variation from country to country and within different communities in childhood as there is in adult cancer. In this connection, a statistical survey- was performed on the primary solid malignant tumors of Korean infants and childhood based on biopay mnter ials. In this study total 700 cases of primary malignant tumors(male 447, female 252 and unknown sex 1) diagnosed during the period of ten years, 1956 to 1967 were colleeted from the major general hospitals thrughout the country. All malignant tumors were classified acearding to the WHO code number. Among solid malignant tumors in both sexes, the .incidence is highest for lymphoma(24. 6%), and thereafter in order of frequency ratios, for retinoblastoma(15.0%), malignant tumors of soft tissue(13. 7%) Wilms' tumor(11. 3%), malignant tumor of gonadal and germ cell (6. 7%), malignant tumor of bone(5. 6%), and neurohlastoma(3.4%), The frequency ratio of malignant tumors among the Korean infants and children show some different points as compared to those of Western European and Amerian populations in that retineblastoma and hepato- cellular earcinoma are more frequent, and among the lymphomas, lympho- sareoma is by far the most frequent type, whereas in the Western countries Hodgkins disease and lymphosareoma oecur about equally.
