Cytomorphological and molecular biological characteristics of the secondary erythroid dysplasia in non-hodgkin’s malignant lymphoma

Abstract

The cytomorphological pattern of bone marrow of 115 patients with non-Hodgkin’s lymphoma beyond the leukemic phase has been investigated. It has been shown that cytomorphological signs of dyserythropoiesis were revealed at the majority of patients before the treatment regardless of the tumor variant. Secondary myelodysplasia is the dominant factor of the patients’ anemia development. Erythroid hematopoiesis disorders are accompanied with the decrease in the expression of CD71-positive cells to erythropoietin receptor. The results testify to the molecular-biological nature of dyserythropoiesis at lymphoid tumors and the presence of pathogenic interconnection between secondary myelodysplasia in the bone marrow and the lymphomagenesis mechanisms.
