Administration of recombinant human erythropoietin alpha before autologous stem cell transplantation reduces transfusion requirement in multiple myeloma patients.
Recombinant human erythropoietin administered after peripheral blood stem cell transplantation (PBSCT) has been ineffective for the treatment of anemia. We administered recombinant human erythropoietin alpha (rHuEPO) prior to high-dose therapy after peripheral blood stem cell (PBSC) collection to evaluate its efficacy on transfusion requirements and hematological parameters during the post-transplant aplastic phase. Twenty-two multiple myeloma patients (EPO-MM) were included in the trial to receive rHuEPO 10,000 IU subcutaneous daily starting 30 days before PBSCT. Forty hemoglobin (Hb)-matched patients who had not received rHuEPO before transplant were retrospectively selected (Ctr-MM) for comparative data. None of the patients received transfusions at study entry. All but one patient responded to rHuEPO. However, no significant differences in Hb levels were obtained between the two groups at the time of transplantation. At nadir, the EPO-MM cases had a significantly higher Hb level (median 10 g/dl versus 7.6 g/d; p=0.001). Consequently, less than 20% of EPO-MM patients required packed red blood cell (PRBC) transfusions compared to more than half the Ctr-MM patients (p=0.007). Furthermore, the number of PRBC transfusions performed in the EPO-MM group was significantly lower (median 0 versus 1; p=0.008). Independently of Hb levels at PBSCT, rHuEPO therapy was significantly associated with a lower risk of transfusion requirement. In conclusion, rHuEPO is shown to be effective when administered prior to high-dose therapy in MM.
