RESUMEN
PURPOSE: Acute lymphoblastic leukemia (ALL) accounts for approximately 75% of all cases of childhood leukemia. We investigated epidemiology, clinical and laboratory features and treatment outcome of the children with ALL in Korea during recent 5 years. METHODS: One thousand forty nine patients were enrolled between January 1994 and December 1998 from 37 major hospitals in Korea. The data regarding the clinical and laboratory features including age, WBC counts at diagnosis, immunophenotype, morphology, cytogenetics and treatment outcome of patients were analyzed retrospectively by review of patient's medical records. Kaplan-Meier survival curves were constructed. The differences between groups analyzed by log-rank test. RESULTS: There were 597 males and 452 females. The distribution between the age 2 and 5 years is most common in 46.1%. The annual incidence rate per 100,000 population varied from 1.6 to 2.2. The 5 year event free survival (EFS) rates according to good prognostic factors were as follows: 67% bet ween 1-9 year of age at diagnosis, 69% in under 10,000/mm3of initial WBC count, 74% in early pre-B cell CALLA ( ) immunophenotype, 65% in L3 morphology, 68% in no CNS invasion. Most of patients were treated by CCG treatment protocol. The 5 year EFS was 63%. Main complications were sepsis (21.8%) and hemorrhage (12.5%). The relapse rate was 15.6%. The common causes of death were sepsis, DIC, pneumonia, relapse. CONCLUSION: Our results could provide the most recent and important information about acute lymphoblastic leukemia of children in Korea.

Secretory carcinoma is one of the least common forms of breast cancer and demonstrates distinctive clinical and pathological characteristics. We herein report a case of secretory carcinoma of the breast in 3 year and 1 month-old girl. At presentation, the patient had a 2.5cm sized mass on her left breast which was firmly attached to the overlying nipple. The aspiration cytologic findings of the tumor were consistent with a secretory carcinoma. After confirming malignancy by frozen section diagnosis, a modified radical mastectomy was performed and secretory carcinoma was finally diagnosed. To our knowledge, secretory breast carcinoma in children has not been reported previously in Korea and this seems to be the youngest case of secretory carcinoma of the breast which had been reported in English literature.
