80%~90% of children with acute lymphoblastic leukemia can live more than 5 years or even long-term survival after chemotherapy, and about 40% of adults with acute lymphoblastic leukemia can live 3~5 years after chemotherapy. Acute lymphoblastic leukemia is a kind of acute leukemia, which is more common in children and less common in adults, and can often be treated with chemotherapy, radiotherapy and bone marrow transplantation. The overall treatment of acute lymphoblastic leukemia in children is more favorable, with a complete remission rate of >90% and a long-term overall survival rate that can reach 85%. The treatment effect of adult acute lymphoblastic leukemia is a bit worse than that of children, and the complete remission rate of patients can reach 85% to 90%, and the long-term overall survival rate is about 40%. Specific therapeutic drugs include cyclophosphamide, vincristine and so on. Aggressive and standardized treatment can improve the survival rate of leukemia, so once diagnosed, early treatment under the guidance of a physician is recommended.
