VAD with or without subsequent high-dose melphalan followed by autologous stem cell support in AL amyloidosis: Japanese experience and criteria for patient selection.
|
| Abstract |
Patients with AL amyloidosis were treated with VAD (vincristine, doxorubicin and dexamethasone) with or without high-dose melphalan followed by auto-PBSCT according to eligibility criteria based on disease severity, and prospectively investigated the therapeutic benefits and complications. Thirty-one patients were enrolled in this study. VAD and subsequent high-dose melphalan with auto-PBSCT were performed only in patients who met all of the eligibility criteria. Among patients ineligible for this treatment, VAD alone was performed in those with satisfactory general status. Eleven patients met the eligibility criteria, and of these, 7 were treated with VAD and subsequent high-dose melphalan with auto-PBSCT. Seven patients received VAD alone, and the remaining 17 were treated with the supportive therapy. Among the 14 patients treated with chemotherapy, 9 (5 of the 7 treated with VAD and high-dose melphalan, and 4 of the 7 treated with VAD alone) showed complete hematological response with apparent improvement of amyloidosis-related clinical symptoms. Serious complications of chemotherapy were cytomegalovirus infection and pneumocystis carinii pneumonia seen in 1 and 2 patients, respectively. These chemotherapies may be effective for reduction of M-protein and are also useful in improving of amyloidosis-induced organ dysfunction. In patients who cannot tolerate high-dose melphalan, VAD alone is a potent therapeutic option, although there are possible harmful effects on the heart and peripheral nerve.
