PURPOSE: It is known that the prognosis of childhood cancer is relatively good, however actual representative nationwide data on childhood cancer, particularly of survival rate, are rare. In this study we attempted to establish the overall survival rate of major childhood cancer.
MATERIALS AND METHODS: The primary source of data of childhood cancer under 15 years of age were the registry files of the Central Cancer Registry Report (Ministry of Health & Welfare) from 1993 to 1997. The above data was compared to death case data files of the same period obtained from the Korea National Statistical Office using the personal identification code. We calculated the 1, 3, and 5 year survival rates using the life table of SPSS and Kaplan-Meier method and compared the survival rate of disease according to prognostic factors.
RESULTS: A total of 6,720 cases of pediatric cancer from the Central Cancer Registry files were computerized and sorted by personal identification (ID) code to extract duplicated cases as well as cases with incomplete data. The final number of cases entered in this study was 4,983. 1) The number of confirmed death cases was 1,448 (29.1%). 2) The disease distribution showed that the most common pediatric cancer was leukemia (1,468/4,983, 29%), followed by brain tumors (503/4,983, 10%), lymphoma (315/4,983, 6%), Wilms tumor (165/4,983, 3%), etc. in order by number of patients. 3) The 5 year survival rate of disease was as follows: overall 62%, acute lymphocytic leukemia 61%, acute non-lymphocytic leukemia 32%, malignant lymphoma 72%, neuroblastoma 47%, medulloblastoma 51%, Astrocytoma 66%, Wilms tumor 83%, etc.
CONCLUSION: We analyzed and report the 5 year survival rate of overall childhood cancer and of each of the twelve major childhood cancers from in Korea 1993 to 1997 to provide basic data on childhood cancer statistics.
