A retrospective clinico-pathologic study of non-Hodgkin's lymphomas classified according to the nomenclatures of Lennert and of Rappaport.

The survival of 88 patients treated for non-Hodgkin's lymphoma 1972-73 have been reviewed. In 49 patients it was possible to do a re-classification of the lymphomas according to Rappaport's and Lennert's classifications. The main obstacle to the classification according to Lennert was inadequacy of the cyto-pathological material. The correlation between survival and pathology was studied and a comparison between the two classifications was made. Lennert's classification was found to have a good reproducibility and to be more accurate than Rappaport's in separating lymphomas with favourable prognosis from those with unfavourable.
