[Non-Hodgkin lymphomas. New histological, cytological and prognostic correlations (author's transl)]

In a homogenous series of 58 patients with non-Hodgkin lymphoma, clinical, histological, cytological and prognostic correlations were investigated by the same pathologists and clinicians, using Kiel's classification. The survival rate at 3 years was 78% for stage I and II lymphomas and 37% for stage III and IV lymphomas. Nodular forms had a better prognosis. There was good correlation between prognosis and Kiel's classification of cytological forms. The survival rate was 81% in low grade malignancy lymphomas and 28% in high grade malignancy lymphomas with immunoblasts, pure centroblasts and lymphoblasts. The poor survival rate of patients with immunoblastic sarcoma was due to a variety of the disease with totally undifferentiated, highly proliferative cells.
