Abstract

In order to shorten the pancytopenic period following high-dose melphalan 140 mg/m2 (HDM) treatment of multiple myeloma patients, we studied the effects of re-infusing granulocyte colony stimulating factor (G-CSF) [Filgrastim, Neupogen]-primed unprocessed whole blood. 30 patients with multiple myeloma were treated with HDM. One litre of blood after 5 or 6 days stimulation with G-CSF (10 micrograms/kg) was drawn, kept unprocessed for 1 day and re-infused 24 h after chemotherapy. Time to granulocyte recovery (> 0.5 x 10(9)/1) and platelet recovery (> 20 x 10(9)/1) were assessed as well as length of hospital stay, number of transfusions and antibiotic use. These 30 patients were compared with 20 historical control patients who were similarly treated but without stem cell support. The response rate was 75% (21/28) including a complete remission (CR) rate of 29% (8/28). Two early deaths due to Aspergillus pneumonia were observed. The median overall survival after HDM has not been reached after a median follow-up of 14 months. 10 patients showed progression at a median of 7 months. Currently, 23 patients are alive with a median follow-up time of 14 months. Haematological recovery was significantly faster in the study group as compared to the historical control group. The neutrophil count reached 0.5 x 10(9)/1 at a median of 14 days after infusion of 1 litre of unprocessed whole blood compared with 38 days in the historical control group. A platelet count of 20 x 10(9)/1 was reached at a median of 26 days compared with 36 days in the historical control group. Length of hospital stay decreased from a median of 43 to 18.5 days. The number of days with antibiotics was reduced from a median of 21 to 6 days. HDM is effective therapy for multiple myeloma. Toxicity of the regimen is considerably reduced by the use of G-CSF-stimulated unprocessed whole blood, an easy to perform and cheap technique to mobilise and collect stem cells.
