[The therapeutic and prognostic meaning of the histological subtype of non-Hodgkin-lymphomas (author's transl)].

The clinical staging has much lesser importance in non-Hodgkin-lymphomas than in Hodgkin-lymphomas. Much more important for prognosis and treatment is there the histopathological subtype. For this reason there are many international activities directed to new ways of the histological classification of non-Hodgkin-lymphomas. Without any doubt Rappaport's proposal is the clinically most used non-Hodgkin-classification but more and more also the proposal of Lennert becomes accepted by clinicians. The immunological approach seemed to be the most promising way to qualify the Non-Hodgkin-lymphoma classification and finally to individualize the management of this type of neoplasia.
