Acute promyelocytic leukemia can be treated by induction therapy, chemotherapy, and supportive therapy. Acute promyelocytic leukemia belongs to acute myeloid leukemia, which is characterized by the abnormal proliferation of a large number of leukemia cells in the bone marrow and other hematopoietic tissues and their entry into the peripheral blood, whereas the normal hematopoietic function is significantly inhibited. 1. Induction therapy: It is a commonly used treatment method, which induces the differentiation of promyelocytic leukemia cells to normal cells through all-trans retinoic acid and arsenite. 2. Chemotherapy: chemotherapeutic drugs such as cytarabine and methotrexate are also effective in acute promyelocytic leukemia. 3. Supportive therapy: red blood cell and platelet transfusion can be used to support the treatment of patients with obvious anemia and bleeding. There may be other treatments for acute promyelocytic leukemia, such as hematopoietic stem cell transplantation. It is recommended to standardize the treatment under the guidance of the doctor, and the above drugs should be used reasonably under the guidance of the doctor to avoid self-medication.
