Abstract:Objective To investigate the therapeutic effectiveness and side effects of ABCD regimen for relapsed/refractory multiple myeloma (MM). Methods Clinical data of 5 patients suffered from relapsed/refractory MM from November 2013 to May 2015 were analyzed retrospectively, including age, sex, peripheral blood and bone marrow characteristics and so on. These patients were treated by ABCD regimen (Epirubicin 40 mg/m2 d1, Carmustine 62.5 mg d1, Cyclophosphamide 600 mg/m2 d1, Dexamethasone 20 mg d1-4) for 3 to 6 course. The therapeutic effectiveness and side effects were evaluated. Results Among 5 patients, 1 patient was male and 4 patients were females with the age ranged from 48 years to 74 years. Their median myeloma cell ratio was 7.75%, median blood serum β2 microglobulin and albumin was 3.3 μg/L and 37.9 g/L before salvage therapy, respectively. The median course of treatment received by the series was 5. After treatment by ABCD regimen, 3 patients achieved partial remission, 1 patient achieved minimal response, 1 patient achieved stable disease. The median progression survival time was 4 months. The main side effects of treatment were grade 2 of gastrointestinal symptom (3 cases) and fatigue (3 cases), 1 case of grade 3 bone marrow and lung infection. Conclusion ABCD regimen is promising for the treatment of relapsed/refractory MM patients in terms of overall response rate and manageable adverse effects.
