Background: We retrospectively determined whether a 3-day short course of palifermin could reduce the toxicity of high-dose therapy (HDT) and autologous blood stem-cell transplantation (ASCT) in patients with multiple myeloma (MM).
Patients and methods: Sixty-seven consecutive patients received 60 mug/kg palifermin for 3 days before HDT with melphalan 200 or 140 mg/m(2) for patients with renal failure (group A). Granulocyte colony-stimulating factor (G-CSF) was applied after ASCT. Data on haematopoietic reconstitution and toxicity were compared with two previously published patient groups from our institution who had received pegfilgrastim but not palifermin (group B, n = 21) and patients who had received neither palifermin nor G-CSF (group C, n = 21).
Results: In group A, patients with renal failure had a significantly higher risk for severe mucositis (64% versus 16%, P < 0.002). Patients with normal renal function who received palifermin experienced significantly less days of hospitalisation (P < 0.05) and less need for narcotic analgesia (P < 0.05), parenteral nutrition (P < 0.05) and erythrocyte transfusions (P < 0.05) in comparison with groups B and C. Time to haematopoietic reconstitution was not compromised by the use of palifermin.
Conclusions: In conclusion, a short 3-day course of palifermin may be able to reduce the toxicity of HDT and ASCT in patients with MM. Patients with impaired renal function at the time of HDT need additional strategies to further reduce the incidence of severe mucositis.
