How long one can live with acute leukemia is related to the classification of the disease, the choice of treatment regimen, the age of the patient and other factors, and varies greatly among individuals. Children with acute lymphoblastic leukemia have a higher cure rate and can survive for a long time, with about 70%-80% of children being cured. The prognosis of acute lymphoblastic leukemia in adults is relatively poor, with a cure rate relatively inferior to that of children, relying on chemotherapy + stem cell transplantation, with a long-term survival rate of less than 50%. As for acute myeloid leukemia, it is classified as low-risk, intermediate-risk and high-risk according to different MICM typing (morphological, immunological, chromosomal, genetic), with different curative effects. Usually M3 type is low risk and can be completely cured by applying all-trans retinoic acid, arsenic agents and other drugs; other types of non-M3 patients, such as those under 65 years of age and not combined with serious diseases, have a complete remission rate of more than 70% and long-term disease-free survival rate of about 50% as long as they receive standard treatment. In general, if a patient with acute leukemia is treated regularly, he or she is likely to live beyond 3 years as long as there is no relapse within a year; after 3 years, if there is still no relapse, he or she is likely to live beyond 5 years; and if there is no relapse for 10 years, he or she is basically considered cured.
