Intensive treatment of multiple myeloma and criteria for complete remission

Abstract

50 previously untreated patients with multiple myeloma received two-phase treatment: repeated cycles of 4 day infusion with vincristine, doxorubicin, and methylprednisolone (VAMP) followed by high-dose melphalan (HDM), with autologous bone marrow transplantation where possible. The overall response rate was 74% (37/50), with 25 patients (50%) achieving complete haematological and biochemical remission. These remissions were associated with a good quality of life as measured by performance status, pain grade, and the reversal of humoral immunosuppression. 6 patients died during the VAMP phase and there was 1 death related to HDM. The achievement of complete remission, as defined here, in such a high proportion of patients is exceptional and may represent a useful advance in the management of myeloma.
