Abstract

SCT is important in the management of multiple myeloma. In the United States, the standard of care is administration of growth factors to accelerate neutrophil recovery after SCT. The need for growth factors after transplant has not been investigated recently. We analyzed a cohort of 166 patients at our institution who underwent autologous transplant for multiple myeloma without receiving growth factors after transplant and compared them with 498 patients who received standard filgrastim beginning on posttransplant day 5. A neutrophil count of 500/L was achieved in a median of 12.5 days in patients receiving growth factor, compared with 13.5 days in those not receiving growth factor (P = 0.001). Platelet engraftment was identical (median, 14.5 days; P <0.12) in both groups, despite a lower median number of CD34 cells infused in patients who did not receive growth factors. Incidence of nonstaphylococcal bacteremia was identical in both groups. The median hospital stay was 3.5 days shorter in the group not receiving growth factor. It is feasible and reasonable to perform autologous SCT for multiple myeloma without administering growth factors.
