The number of years a child can live with acute lymphoblastic leukemia should depend on the severity of the disease. In general, if the disease is well controlled and the disease is completely cured, the maximum life expectancy is normal. Children with acute lymphoblastic leukemia have a good prognosis and a high cure rate. Therefore, children with the disease generally have a high survival rate and long survival time. However, childhood acute lymphoblastic leukemia requires further risk stratification. 1. In general, with low-risk acute lymphoblastic leukemia, a complete cure is possible with chemotherapy alone (cyclophosphamide, vincristine), and such patients usually live to a normal life expectancy. 2. However, in high-risk acute lymphoblastic leukemia, even if remission is achieved through chemotherapy, there is a possibility of relapse, and once relapse occurs, the effect of chemotherapy is often less satisfactory, and the survival time will become shorter, so it is necessary to use allogeneic hematopoietic stem cell transplantation to achieve a cure for the disease and to prolong the life expectancy. The survival time of children with acute lymphoblastic leukemia is also related to other factors, such as their own physical condition, etc. It is recommended to maintain a good mood, take medication on time, have regular checkups, and follow the doctor’s instructions, so that the condition can be well controlled and the disease can be cured completely. The medication should be administered under the guidance of a physician.
