[Value of the Kiel morphological classification in the clinical aspects of non-Hodgkin's lymphoma].

After an estimation of the 3 years treatment results and the survival probability in 99 patients with non-Hodgkin's lymphomas it was found that the use of Kiel classification made possible isolation of two clinical forms differing in their prognosis. The 3 years survival of the low-grade (LG) group involving the lymphocytic, the centrocytic and the centrocytic-centroblastic lymphomas has been obtained in 43%, 40% and 69% of patients, respectively (mean 57%). The high-grade (HG) group involving the centroblastic, the immunoblastic, the lymphoblastic and the nonclassified lymphomas shoved the 3 years survival corresponding to 22%, 20%, 7% and 30%, respectively (mean 19%). In both morphological subgroups (LG and HG) the prognosis was better in patients with the limited extent and extranodal localization of the neoplasm. The only possibility of achieving cure was obtaining of full remission.
