白血病分类(Leukemia classification) The medical profession is now generally divided into three major types of leukemia, namely acute leukemia, chronic leukemia and special types of leukemia. Each type of leukemia cells according to the change of different separation of different subtypes, the doctor can make a detailed classification of leukemia therapy for the patients. The (I) criteria for the classification of leukemia Cell differentiation is blocked at an earlier stage, and most of the differentiated white blood cells are in the primitive or early stage, and the disease is short, rapid onset, rapid development, serious disease, acute leukemia. Acute leukemia includes acute myeloid leukemia and acute lymphoblastic leukemia. The The cell differentiation has mature ability greatly, most of its cells into mature cells, a few block in the intermediate or late stage of immature cells, and slow onset, mild illness, longer duration of chronic leukemia. Chronic leukemia includes chronic myelogenous leukemia and chronic lymphocytic leukemia. The In addition, there are some rare or rare type of leukemia, such as eosinophilic leukemia, basophilic cell leukemia, hairy cell leukemia, prolymphocytic leukemia, megakaryocytic leukemia, adult T cell leukemia, plasma cell leukemia. The (two) the type of acute leukemia 1. acute myeloid leukemia (AML) is divided into Acute myeloid leukemia with minimal differentiation (MO): the degree of hyperplasia of bone marrow nucleated cells is relatively small, and the original cells are more than 30%, which can reach more than 90%. The (II) acute myeloid leukemia undifferentiated (M1): bone marrow hyperplasia is extremely active or obviously active, a few cases can proliferate and decrease. The type I + II type granulocyte in the bone marrow is more than 90% (NEC). The The original acute myelocytic leukemia with maturation (M2) bone marrow hyperplasia hyperactive or significantly active, the Central Plains type I type I bone marrow particles great
