The treatment for acute leukemia is chemotherapy. Chemotherapy can be administered orally or intravenously, and the choice between oral or intravenous chemotherapy depends on the type of acute leukemia. For patients with acute leukemia, if chemotherapy alone can effectively control the disease or achieve a cure, then there is no need for allogeneic hematopoietic stem cell transplantation. However, if chemotherapy alone cannot control the disease, and the patient is considered at high risk and of suitable age, then allogeneic hematopoietic stem cell transplantation should be considered.
