Use of recombinant human hematopoietic growth factors and autologous bone marrow transplantation to attenuate the neutropenic trough of high-dose therapy.
This manuscript summarizes our experience with recombinant human granulocyte colony-stimulating factor (rhG-CSF) with high-dose Cytoxan, carmustine and etoposide (CBV in Hodgkin's disease). rhG-CSF regularly shortened the neutropenic phase following autologous bone marrow transplantation. However, this effect was more marked on the latter part of neutrophil recovery than the early part of granulocyte recovery to 100 granulocytes/microliters. The frequency of afebrile episodes was not reduced by rhG-CSF administration, but there was a tendency for the duration of fever to be shortened. Increasing doses and continuous infusion did not hasten the early part of neutrophil recovery needed to prevent the onset of infection, but was more effective than bolus infusion in increasing the rate of late neutrophil recovery. If fevers are to be prevented in this patient population, the duration of an absolute granulocyte count of less than 100/microliters will have to last only a few days. Recombinant hematopoietic growth factors alone do not hasten recovery fast enough to prevent the onset of afebrile episodes. Studies are described using both recombinant growth factor and peripheral blood and bone marrow cells to see if the neutropenic trough can be further shortened over that achievable with growth factor and autologous transplant alone.
