Hemopoiesis and functional activity of monocytes were assessed in 30 patients with chronic myelomonocytic leukemia (CMML). Changes in haemogram in CMML are characterized by anemia, thrombocytopenia, normal or increased count of leukocytes with absolute monocytosis and increased count of young granulocytes. Bone marrow hemopoiesis is characterized by enhanced proliferation of cellular elements of granulocytopoiesis and monocytes, suppressed erythropoiesis and megakaryocytopoiesis. Dysplastic changes are most expressed in the erythrocytic stem cells. Studies of lysosomal enzymes showed their increased activity in monocytes of CMML patients.

Basing on computer processing of 126 primary clinical and laboratory parameters obtained from 92 patients with myelodysplasia and using multifactorial regression analysis, the authors have developed prognostic models of life span and probability of transformation into acute leukemia. The model of life span enabled recognition of 3 prognostic groups of myelodysplasia patients: of high (median 10 months), moderate (median 22 months) and low (median 35 months) risk. This makes it possible to prognosticate the disease and assume optimal therapeutic policy.
