[Clinical aspects and prognosis of highly malignant non-Hodgkin's lymphomas]

Clinical data and courses of the disease of 56 patients with non-Hodgkin-lymphomas of high malignancy were demonstrated. The age-depending summit of the frequency was between the 51st and 60th year of age, the age median was about 48 years. The initial remission rate three months after the beginning of the therapy was 66%. Out of the responders in 44% relapsed, in which cases 70% of the relapses developed in the first year after the beginning of treatment. After twelve months the survival rate was 0.52 and after 48 months 0.32. Patients with initial remission, with localized stages I and II (Ann Arbor) as well as with primarily extranodal manifestation and with histology of centroblastoma had a clear prognostic advantage. Initial B-symptomas, an advanced stage of the disease and a histology of immunoblastoma and lymphoblastoma as well were negatively correlated to the prognosis.
