    Abstract:
    The author evaluated the effectiveness of a combination of G-CSF with high-dose Ara-C (HD Ara-C) or high-dose etoposide based on the collection of peripheral blood stem cells (PBSC) during the recovery phase from myelosuppression in 17 patients with various types of hematopoietic malignancies. Following therapy with HD Ara-C or HD etoposide, G-CSF (250 micrograms/body) was administered from the nadir state and blood mononuclear cells were collected using a CS-3000 by processing 15 litres of blood at each apheresis. Stem cell-enriched fractions obtained from discontinuous Percoll gradients were collected and stored in liquid nitrogen. The mean numbers of granulocyte-macrophage colony-forming units (CFU-GM) obtained by the first apheresis were 10.9 x 10(5)/kg after chemotherapy with HD Ara-C and 13.4 x 10(5)/kg after HD etoposide therapy, respectively. In 14 out of the 17 first apheresis, more than 2 x 10(5) CFU-GM/kg were collected. Serial apheresis was performed in seven patients, at intervals ranging from 21-79 days, and the progenitor yield in the second apheresis decreased in five patients. These results suggest that the use of either HD Ara-C or HD etoposide induces an effective mobilization of PBSC and enables large scale collection of PBSC for autotransplantation.
