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.
