[Chronic myelomonocytic leukemia].

Retrospective analysis of 23 cases of chronic myelomonocytic leukemia (CMML) was presented. Clinical findings, peripheral blood and bone marrow indices, ultrastructural, cytochemical, biochemical (the level of serum and urine lysozyme), cytogenetic investigations as well as the type of leukemic cell growth in culture (monolayer) were considered. Proceeding from the above analysis, the authors found it appropriate to attribute CMML to myelodysplasia.

[Familial myeloproliferative syndrome (study of 4 families and review of the literature)].

The authors describe 4 families whose members showed myeloproliferative diseases. In one of the families, polycythemia vera (PV) was seen in twin brother and sister, in the other one, chronic myeloleukemia (CML) afflicted both daughter and mother, and in the two remaining families PV and CML afflicted two brothers and mother and daughter, respectively. It was established that neutrophil phosphatase activity was lowered not only in the afflicted brother but also in healthy members of the third family.

[Therapeutic results in malignant lymphomas treated by the COPP and POPP drug administration schedules].

The paper deals with a comparison of the results of treatment of 19 patients with malignant lymphomas, mostly diffuse ones, stage 3, by POPP schedule (paphencyl, vincristine (oncovine), procarbosin (natulan) and prednisolone) and 37 similar patients who received a modified standard COPP treatment. Following six courses of POPP treatment, the frequency of complete remission was significantly higher (83 and 51% respectively). Therefore, this schedule of therapy may be recommended for a large-scale application.
