Short and long-term outcome of treatment with high-dose melphalan and stem cell transplantation for multiple myeloma-associated AL amyloidosis.
High-dose melphalan chemotherapy and autologous peripheral blood stem cell transplantation (HDM/SCT) has been shown to result in a durable hematologic response and prolonged overall survival in systemic amyloid light-chain (AL) amyloidosis as well as multiple myeloma. However, little is known about the myeloma associated with AL amyloidosis (MM/AL). In this retrospective study, we evaluated 87 patients with MM/AL from 1994 to 2007. Sixteen of these patients underwent HDM/SCT at Boston University Medical Center. Three patients (19%) died from treatment-related mortality. The overall median survival for all 87 patients was 22 months by Kaplan-Meier estimates. However, this was improved to 54.5 months for those who received HDM/SCT compared to 21 months for those who did not receive HDM/SCT. A hematologic complete response was achieved by 25% (4/16) of patients at 6 months after HDM/SCT. Hematologic relapses occurred in 60% of patients at a median of 1 year after HDM/SCT. In conclusion, HDM/SCT can prolong overall survival in patients with MM/AL who are eligible to receive it.
