[The Lukes-Collins classification and the Kiel classification of non-Hodgkin's lymphomas]

280 cases of non-Hodgkin lymphoma were studied histologically according to the criteria of Lukes-Collins as well as Lennert's classifications. Nodularity was predominantly related to the SC and LC types according to the Lukes-Collins classification. Nodularity is indicative of better survival. The Burkitt and convoluted types were found to be predominantly related to childhood or to younger patients and the non-Burkitt type most frequently to the older groups. The Lukes-Collins classification separates well two clear prognostic groups--the favorable and the unfavorable one with overall median survivals of 44 and 11 months, respectively. Within the Kiel classification, nodularity was found mainly in the CB-CC type, but also in 27% of the CC cases. The relationship of the subtypes according to the Kiel classification and age resembles the same relation found with the Lukes-Collins classification, where according to the Kiel classification the Burkitt, convoluted and lymphoblastic types were related to children and adults. Three prognostic groups were identified with overall median survivals of 80, 38 and 13 months, respectively.
