Approximately 75% of cases occur in children under six years of age. This is a good prognosis leukemia. In the pediatric age group the complete remission rate is approximately 95% and the disease free survival rate is 70%. Approximately 80% of children appear to be cured. In the adult age group the complete remission rate is 60-85%.
