Phase-I?II study of high-dose melphalan and autologous marrow transplantation in adult patients with poor-risk non-Hodgkin's lymphomas

Abstract

Eleven adult patients with poor-risk non-Hodgkin's lymphoma were treated with high-dose melphalan (140 mg/m²) or high-dose combination chemotherapy (BCNU, Ara-C, vindesine and melphalan) followed by autologous bone marrow transplantation. Six of the eight patients evaluable for response achieved complete remission and one achieved partial remission. Response duration ranged from 1.5 to 12 months (median 2 months). Prompt hematological recovery occurred in all patients. The duration of aplasia and the extrahematological toxicity were similar in both groups. High-dose melphalan alone or associated with other drugs followed by marrow infusion appears to produce a high response rate and demonstrates the potential for salvaging patients with refractory lymphoma.
