[Prognostic factors in non-Hodgkin's malignant lymphoma].

: A group of 271 patients with non-Hodgkin's malignant lymphomas from years 1975-1989 was tested using multivariant statistical analysis, from the point of view of the prognostic value their basic clinical and laboratory data. In the group of low grade malignancy lymphomas, the following factors showed a prognostic validity: clinical stage, general status, centrocytic histological subtype, and anaemia. In the group of high grade malignant lymphomas following one were set as prognostically important: general status, clinical stage and age. In particular histological subtypes of low grade malignancy statistically valid difference of survival was not proved, the centrocytic type excluded. However, the difference was found between these types and particular subtypes of high malignancy grade. Based on these results, the Cox's risk model was made, enabling us to define 4 risk groups according to the histological subtype and clinical stage: group A (risk less than 0.5), group B (risk = 0.5-1.0), group C (risk = 1.0-2.0), group D (risk greater than 2.0).
