Abstract
A population-based cancer registry for childhood leukemia was started in Hungary in 1971. Data processing and analysis have been done at the Second Department of Pediatrics, Semmelweis University Medical School in Budapest, which is the main center for the treatment of childhood malignancies in Hungary. In 1992 a new computerized database structure was created in collaboration with Kansas University Medical Center, Kansas City, Kansas, United States. This work presents childhood leukemia frequency distribution and treatment results between 1988 and 1992 in Hungary. The number of patients diagnosed with leukemia under 18 years of age fluctuates between 69 and 82 cases per year. We present the main causes of death and outline our future objectives to improve the survival rate and quality of life.
