How long leukemia patients can live is related to the treatment efficacy, severity of complications, and the presence of high-risk factors, etc. Some patients can only survive for 2~3 months, while some patients’ survival period can be up to a few years or dozens of years, and even some patients can survive for a long time. 1. After the diagnosis of leukemia is clear, patients need to be treated with induction chemotherapy immediately, the drugs include Zoerythromycin, cytarabine, etc. If the patients can not achieve remission by induction chemotherapy, the condition is serious, and most of the patients can only survive for 2~3 months. 2. If patients achieve remission after induction chemotherapy, further intensive consolidation and maintenance chemotherapy, bone marrow transplantation and other treatments can be carried out, so that the patients can achieve a long period of sustained remission, and their survival period can be from several years to several decades. 3. In the course of combination chemotherapy or bone marrow transplantation, patients may experience serious infections, intracranial hemorrhage and other complications, which may be life-threatening when the condition is serious, so the survival of patients is also affected by the severity of the complications. 4. If the patient is accompanied by more high-risk factors, such as chromosome mutations like t(8;21), the prognosis of the disease is poorer, and the survival period of these patients is relatively shorter. Therefore, the survival period of leukemia patients varies from person to person, and is affected by a combination of the above factors, and should be actively treated under the guidance of physicians.
