With the continuous development of medical diagnosis and treatment technology, the saying that leukemia is an “incurable disease” is already a thing of the past, and many patients can be cured or in long-term remission by adopting adequate, combined, individualized and other joint treatments at the early stage of the disease. If patients are diagnosed with leukemia and receive active treatment, they can effectively kill leukemia cells, relieve various clinical symptoms caused by low immunity due to the infiltration of leukemia cells, and achieve complete remission of leukemia symptoms to save their lives. As the clinical typing and prognostic factors of leukemia are very complicated, it is necessary for clinicians to comprehensively analyze the patients according to their leukemia typing and prognostic factors, and the patients need to undergo active treatment. Specific treatment methods vary according to the type of leukemia, such as chronic lymphocytic leukemia to be imatinib and other oral treatment, acute myeloid leukemia to be cytarabine, Zoerythromycin and other drugs chemotherapy. Specific disease diagnosis and treatment should be carried out under the guidance of physicians.
