RESUMEN

Objective To compare the clinical effect of ifosfamide in combination with liposomal doxorubicin and dexamethasone (CDD) in the treatment of relapsed/refractory multiple myeloma (MM) with or without extramedullary plasmacytoma (EMP). Methods The clinical data of 71 relapsed/refractory MM patients treated with CDD regimen from January 2011 to December 2016 were retrospectively analyzed, including 48 patients with EMP(group A)and 23 patients without EMP (group B).One cycle of the CDD treatment was 21 d or 28 d and efficacy analysis was performed after every two cycles.Results The overall response rate in group A was 43.8%(21/48)and the complete remission and near complete remission rate was 8.3%(4/48);the overall response rate in group B was 65.2%(15/23)and the complete remission and near complete remission rate was 13.0% (3/23). There were no statistically significant differences between the two groups(χ2=1.203,0.659,P>0.05).The progression-free survival (PFS)time in group A was(8.6 ± 3.3)months, while the PFS time in group B was(7.9 ± 2.5)months and there was no significant difference between the two groups(t=1.009,P>0.05).There was no significant difference about incidence rate of adverse effects between the two groups(P>0.05).Conclusions CDD regimen can be used for the treatment of relapsed/refractory MM with or without EMP, the PFS and drug related adverse effects are similar, especially in patients with EMP.
