MSH: The initial phase of chronic myeloid leukemia consisting of an relatively indolent period lasting from 4 to 7 years. Patients range from asymptomatic to those exhibiting ANEMIA; SPLENOMEGALY; and increased cell turnover. There are 5% or fewer blast cells in the blood and bone marrow in this phase.,NCI: A phase of chronic myelogenous leukemia in which fewer than 10% of the cells in the blood and bone marrow are blast cells (immature blood cells). This phase may last from several months to several years, and there may be no symptoms of leukemia.,NCI: A phase of chronic myelogenous leukemia in which the peripheral blood smear shows leukocytosis due mainly to neutrophils in different stages of maturation. Blasts usually account for less than 2% of the white blood cells counts. The platelet count is normal or increased. Thrombocytopenia is very uncommon during the chronic phase. Most patients have mild anemia. The bone marrow biopsy is hypercellular due to increased numbers of neutrophils and their precursors
