Leukemia Leukemia may be may be acute, acute, with a sudden onset and short duration, or with a sudden onset and short duration, or chronic, chronic, with a slow onset and persistent symptoms over a period of with a slow onset and persistent symptoms over a period of yearsyears

Leukemias are categorized by the specific maturational pathway from Leukemias are categorized by the specific maturational pathway from which the abnormal cells arise. which the abnormal cells arise.

Leukemias in which the abnormal cells arise from within the Leukemias in which the abnormal cells arise from within the committed lymphoid maturational pathways are committed lymphoid maturational pathways are lymphocytic lymphocytic or or lymphoblastic. lymphoblastic.

Leukemias in which the abnormal cells arise within the committed Leukemias in which the abnormal cells arise within the committed myeloid maturational pathways are myeloid maturational pathways are myelocytic myelocytic or or myelogenous. myelogenous.

Several subtypes exist for each of these diseases, which are classified Several subtypes exist for each of these diseases, which are classified according to the degree of maturity of the abnormal cell and the according to the degree of maturity of the abnormal cell and the specific cell type involvedspecific cell type involved

This situation leads to anemia, thrombocytopenia, and leukopenia This situation leads to anemia, thrombocytopenia, and leukopenia of the unaffected WBC types, even though the number of of the unaffected WBC types, even though the number of immature, abnormal WBCs in the circulation is greatly elevated. immature, abnormal WBCs in the circulation is greatly elevated.

Without treatment, the client usually dies of infection or Without treatment, the client usually dies of infection or hemorrhage. For clients with acute leukemias, these pathologic hemorrhage. For clients with acute leukemias, these pathologic changes occur rapidly and, without intervention, progress quickly changes occur rapidly and, without intervention, progress quickly to death. Chronic leukemia may be present for many years before to death. Chronic leukemia may be present for many years before overt pathologic changes occurovert pathologic changes occur

Induction therapy. Induction therapy. Induction therapy is intensive and consists of Induction therapy is intensive and consists of combination chemotherapy initiated at the time of diagnosis. This combination chemotherapy initiated at the time of diagnosis. This therapy is aimed at achieving a rapid, complete remission of all therapy is aimed at achieving a rapid, complete remission of all manifestations of disease. A typical course of aggressive manifestations of disease.
