Acute myeloid leukemia M4 is acute granulomonocytic leukemia, a malignant disease originating from abnormal proliferation of hematopoietic stem cells. It is a malignant disease that originates from the abnormal proliferation of hematopoietic stem cells. It is explained below in terms of causes, symptoms and treatment. 1. Acute myeloid leukemia M4 is a malignant disease in which hematopoietic stem cells and progenitor cells lose their ability to further differentiate and mature, so that the cancer cells proliferate unrestrictedly, thus gradually replacing the normal bone marrow cells and infiltrating the tissues and organs of the whole body through the bloodstream. At the same time, there will be anemia, infection, bleeding, swollen gums and other symptoms. 2. AML M4 can be cured by chemotherapy drugs such as cytarabine and demethylation drugs such as decitabine, which can directly kill tumor cells. Targeted drugs such as Vinaclat and Gitolizumab can also be used to cure AML M4, which can be standardized in the process of using drugs and should not be stopped without authorization. Hematopoietic stem cell transplantation has the best curative effect, but the cost is high and a suitable donor has to be found. Patients with acute myeloid leukemia M4 need to go to the hospital in time and receive treatment under the guidance of a physician, and follow the doctor’s instructions for treatment and medication.
