Acute leukemia is a malignant proliferative disease caused by abnormal proliferation and differentiation of hematopoietic stem cells. Depending on the type of proliferating leukocytes, it is divided into acute lymphoblastic leukemia and acute non-lymphoblastic leukemia. The cure of acute leukemia in children needs to be analyzed according to the type of acute leukemia, most of which can be cured.1. Acute lymphoblastic leukemia: more than 80% of clinical cases are acute lymphoblastic leukemia. The treatment of this type of leukemia is mainly a combination of chemotherapy-based therapy, with a relatively good prognosis. Acute children can basically remit after induction consolidation therapy. After formal treatment, such as strengthening supportive therapy, preventing and controlling infections, and component blood transfusion, etc., and continued treatment for 2-3 years, 70%-80% of children can be cured and achieve a 5-year survival rate. In a very small number of children, complications during chemotherapy or poor genetic type can lead to incomplete cure; 2. Acute non-lymphoblastic leukemia: such as acute myeloid leukemia, which is relatively difficult to treat. For this disease, stem cell transplantation is generally recommended, which can lead to a significantly improved prognosis for children. After regular treatment lasting 2-3.5 years, complete remission rates can reach 80%, 5-year survival rates of 40%-60%, and long-term survival rates of 50%. With early diagnosis, early treatment and active cooperation, most children with acute leukemia can be cured.
