[Retrospective analysis of the clinical relevance of the Kiel classification of malignant non-Hodgkin's lymphomas (author's transl)].

405 cases with non-Hodgkin's lymphomas have been diagnosed according to the Kiel classification and analysed retrospectively. 314 patients with non-Hodgkin's lymphomas of low-grade-malignancy (chronic lymphocytic leukemia, lymphoplasmacytoid, centrocytic, centrocytic, centroblastic-centrocytic lymphoma) manifested significantly higher median survival times than the 91 patients with non-Hodgkin's lymphomas of high-grade malignancy (lymphoblastic and immunoblastic lymphoma). Within the group of patients with low-grade malignant lymphomas distinct prognostic differences were found whereas survival times in patients with lymphoblastic or immunoblastic lymphomas were rather similar. The lymphoblastic lymphoma showed a bimodal curve of age distribution whilst all other lymphomas had a maximum of incidence in the seventh decade of life. Increased frequency of B-symptoms did not necessarily represent an unfavorable prognostic factor for the lymphoma entity concerned. Except for chronic lymphocytic leukemia the highest incidence of initial bone marrow involvement was seen in lymphoplasmacytoid, centrocytic and lymphoblastic lymphomas. Centrocytes have been observed in peripheral blood of patients with centrocytic and centroblastic-centrocytic lymphomas, even though lymphocytosis did not exist. Monoclonal hypergammaglobulinemia was found in only 43% of the sera from patients with lymphoplasmocytoid lymphoma. In this disease, it was possible to differentiate between a lymphonodal, a splenomegalic and an extranodal manifestation.

Multicentre randomized therapeutic trial for advanced centrocytic lymphoma: anthracycline does not improve the prognosis.

Within a multicentre observation study on non-Hodgkin lymphomas (NHL) diagnosed according to the Kiel classification advanced stages III and IV of centrocytic (CC) lymphoma exhibited the worst prognosis among lymphomas of low-grade malignancy with a 5-year survival probability of less than 10 per cent. Treatment had been solely expectative and palliative with treatment results showing a prognostic superiority of patients achieving partial and complete remissions over non-responders. Therefore, a randomized multicentre study was initiated to compare the remission-inducing potential of the COP regimen (Bagley et al., 1972) with that of the more intensive adriamycin-containing CHOP regimen (McKelvey et al., 1976). From 91 newly diagnosed CC lymphomas 63 fulfilled randomization criteria with 37 patients assigned to the COP regimen and 26 patients to the CHOP regimen. Between the COP- and CHOP-treated patients no significant differences could be demonstrated with respect to initial clinical parameters, rate of complete (41 per cent versus 58 per cent) or partial remissions (43 per cent versus 31 per cent), median overall survival probability (32 versus 37 months), relapse-free survival (10 versus 7 months) and rates of relapse (73 per cent versus 67 per cent) and death (57 per cent versus 50 per cent). It can be concluded that CC lymphoma is a typical lymphoma of low-grade malignancy with its inability to reach stable remissions while the demonstration of identical survival probabilities for patients with complete and partial remissions constitutes a unique feature of this lymphoma entity. These observations prove advanced CC lymphoma to represent an incurable neoplastic disease under conventional therapeutic approaches.
