Abstract

Background and objectives: High-dose chemotherapy (HDT) with autologous peripheral blood progenitor cell (PBPC) transplant has been increasingly used for newly diagnosed multiple myeloma (MM) in recent years. Presently available results suggest an improvement in the complete remission rate and survival as compared to conventional chemotherapy. However, there is no plateau in the survival curves, and experiments with new treatment schedules and conditioning regimens are warranted. Design and methods: In a non-randomised controlled trial, 20 patients underwent three-step HDT following conventional vineristine/doxo ulicin/dexamethasone (VAD)-based induction. In the intensification phase patients received high-dose cyclophosphamide (HD-CY), high-dose etoposide (HD-VP), and mitoxantrone (NOV) plus melphalan (L-PAM) with haemopoietic rescue. Maintenance treatment with interferon was given until relapse. Actuarial overall survival (OS) and event-free survival (EFS) curves were plotted according to the method of Kaplan and Meier. In five of the eight patients achieving complete remission (CR), the molecular disease was monitored by polymerase chain reaction technique (PCR). Results: Overall 18/20 (90%) patients responded, with a CR rate of 40%. After an average follow-up of 40 months, median EFS and OS are 25.5 and 44.6 months, respectively. Monoclonal cells were detectable in the post-treatment bone marrow and in the aphereses of the five CR patients monitored by PCR. Conclusion: The present three-step HDT regimen, including conditioning with mitoxantrone and melphalan, proved to be feasible and safe. Our results are in agreement with the hypothesis that HDT results in an increased remission rate and in prolonged survival in newly diagnosed MM, but a cure is unlikely.
