ABSTRACT
The effects of a synthetic prostaglandin E1 (PGE1) analog on colony-forming activity in agar cultures of peripheral blood and bone marrow was studied in 28 patients with chronic myeloid leukemia and 9 hematologically healthy subjects. Addition of PGE1 to normal bone marrow culture was followed by a significant drop in the number of colonies per dish in 8 out of the 9 subjects. In leukemic patients, the effect was bizarre. It proved to be in correlation with survival thus suggesting that the effect of PGE1 on colony-forming activity of granulocyte-macrophage precursors be used in predicting survival in patients with chronic myeloid leukemia.

The authors report the results of the clinical, cytochemical, cytogenetic and kinetic studies (3H-thymidine autoradiography and scanning integrating cytospectrophotometry of DNA) in a male patient with chronic myeloleukemia with blast infiltration of the lymph nodes. Analysis of the karyotype and kinetic aspects of leukemic cells obtained from the blood, bone marrow, spleen and hyperplastic lymph nodes was performed over time at different disease periods. Based on the data obtained the authors suggest that aneuploid blasts may maturate before segmented granulocytes. The probability of the medullary origin of aneuploid clones is discussed.
