    Abstract:
    Clinical experiences with recombinant granulocyte colony-stimulating factor (rhG-CSF) in 13 acute (AML) and four chronic (CML) myelogenous leukemia patients are reported. Sixteen patients received rhG-CSF in support of treatment for life threatening infections and one CML patient in support of induction chemotherapy. After their first induction chemotherapy, six out of eight AML patients showed a rapid increase of neutrophils, recovered from infections and achieved complete remission (CR). One patient, in whom both neutrophils and blasts had increased during rhG-CSF administration, achieved CR through the next administration of chemotherapy (CR rate 87.5%). The last of the eight AML patients showed no increase of neutrophils, and died of interstitial pneumonitis. Two of five AML patients who received rhG-CSF after reinduction chemotherapy for relapsed or refractory leukemia achieved CR, a rate of 40%. In one of the two, the administration of rhG-CSF prior to induction chemotherapy seemed advantageous in achieving CR. During rhG-CSF administration, an increase of blastic cells in peripheral blood was observed in four out of all 13 AML patients. One of three CML patients, with a lymphoid crisis, showed an increase only of neutrophils, and recovered from infection. The other two showed increases of both neutrophils and blasts. One patient with CML in blastic crisis, undergoing induction chemotherapy with rhG-CSF administration, returned to the chronic phase. These clinical experiences suggest rhG-CSF to be effective in supporting infection therapy and in possibly enhancing the sensitivity of myelogenous leukemic blasts to antileukemic agents.
