title: [Progress in the treatment of multiple myeloma].
abstract: Melphalan and prednisolone (MP) have been the standard therapy for multiple myeloma for more than 25 years. Although they produce an objective response in 50-60% of patients, complete remission (CR) is rare and the median survival period is generally 24 to 30 months. Many combination chemotherapeutic agents have been used and resulted in approximately 70% objective response, but the median duration of survival has not significantly been improved. VAD regimen is effective for many patients with myeloma resistant to MP therapy. Furthermore, VAD-cyclosporin combination induces responses in approximately 40% of patients with VAD-resistant myeloma, with increased expression of the multi-drug resistant gene (MDR). Intravenous administration of high dose-melphalan also produces responses in approximately 30% of patients with myeloma resistant to VAD. Interferon-alpha therapy with an alkylating agent-glucocorticoid regimen, shows a higher response rate but similar survival time, compared with those obtained with the MP therapy alone. High-dose therapy with transplantation is promising. High-dose therapy combined with autologous bone marrow transplantation improves the response rate, event-free survival (EFS), and overall survival (OS) in patients with myeloma, demonstrated in the prospective, randomized trial by Attal et al. Total therapy by Barlogie et al. consisted of non-cross-resistant induction regimens, followed by a double autotransplantation (AT) procedure. Compared with the outcome of patients receiving standard therapy, dose intensification with double AT produces not only higher CR rates but also significantly extends EFS and OS in previously untreated patients with myeloma. The reduced mortality rate associated with transplantation, and development of new chemotherapeutic agents will lead to future improvements of the therapy for multiple myeloma.
