Abstract

Different histopathologic classifications have been used in the study of malignant lymphomas. The clinical relevance (reproducibility, prognostic value) has not been precisely studied. The "non-Hodgkin's lymphoma classification project" has been organized to study a cohort of 1,403 cases in 9 sites around the world consisting of consecutive patients seen between 1988 and 1990 in order to have a good follow-up. The reproducibility of the up-dated Kiel and the ILSG (REAL) classifications between the 5 visiting expert hematopathologists was pretty good, at least 85% for the majority of the entities. According to survival curves, the lymphomas can be stratified in 4 different groups. Comparison with the international prognostic index demonstrate that for therapeutic strategy both histopathology and index should be used. The results bring a good support to the project of the WHO to propose the first international classification of lymphomas based on both forme classifications.
