Acute lymphoblastic leukemia has a different cure time depending on the risk stratification of the condition and treatment options. It is not possible to determine a specific cure time. 1. Chemotherapy can only be terminated when the condition of the leukemia patient is in complete remission and the results of the micro-residual leukemia test are negative after active intensive consolidation treatment or after receiving allogeneic (or autologous) stem cell transplantation. For patients with different risk stratification, there are some differences in the treatment time and treatment method, and the time of cure also varies. 2. For leukemia patients whose condition is not yet in remission, if life-threatening serious infection or bleeding occurs during the treatment period, the treatment can be suspended and the cure time will be extended accordingly. If the patient’s condition is not in remission after multiple cycles of chemotherapy, the cure time will be extended accordingly. The treatment of acute lymphoblastic leukemia is complicated and lasts for a long time, and the toxic side effects produced by chemotherapy (cyclophosphamide, vinblastine) are a great test for the patients. In daily life, patients should keep a good mindset, actively cooperate with the doctor’s treatment, and undergo regular checkups to strive for a speedy recovery. The medication should be administered under the guidance of a physician.
