Specific Features of Interactions between Megakaryocytic and Granulocytic Hematopoiesis Lineages and Myelofibrosis during the Acute Phase of Chronic Myeloid Leukemia, Chronic Lymphocytic Leukemia, and Multiple Myeloma

The specific features of interactions between megakaryocytic and granulocytic hematopoiesis lineages and myelofibrosis were studied in patients with active phase (before treatment) of chronic myeloid leukemia, chronic lymphocytic leukemia, and multiple myeloma. In patients with chronic myeloid leukemia, a direct correlation was found between the severity of both early and advanced myelofibrosis and the number of megakaryocytes in the bone marrow irrespectively of the type of the bone marrow tumor. The parameters of granulocytic hematopoiesis lineage were higher in myelofibrosis. In patients with chronic lymphocytic leukemia and multiple myeloma, negative correlations between the severity of early and advanced myelofibrosis and the number of megakaryocytes in the bone marrow and platelets in the peripheral blood were found. In chronic lymphocytic leukemia, negative correlations between the severity of early and advanced myelofibrosis and the number of neutrophils in the bone marrow and peripheral blood were detected. In patients with multiple myeloma, negative correlations between the severity of advanced myelofibrosis and number of neutrophils in the bone marrow and peripheral blood were detected.
