title: [Nucleolar organizer as a marker of malignancy grade and prognosis of non-Hodgkin's malignant lymphoma].
abstract: There were 51 cases of non-Hodgkin's malignant lymphoma (NHL) and 9 cases of reactive follicular hyperplasia among 60 cases of lymphoproliferative conditions. According to the Kiel classification, lymphomas of a low grade of malignancy (17 cases) and lymphomas of a high grade of malignancy (34 cases) were distinguished among NML. Significantly higher activity of the nucleolar organizers (NO) was observed in lymphomas of a high malignancy grade, particularly in lymphomas formed of cells of early differentiation stages, and enhancement of NO activity with development of lymphoma aggression. "Anomalies" of NO activity expression reflecting clinical lymphoma presentation were noted among NML of various malignancy grade. NML with a high NO activity are described as having less favourable prognosis compared to lymphomas with low NO activity. No significant difference in NO activity was found between reactive follicular hyperplasia and follicular centroblast-centrocytic lymphoma. Thus, NO activity can be considered as an additional diagnostic marker of NML grade of malignancy and prognosis.
