Recombinant human granulocyte-macrophage colony-stimulating factor (rHuGM-CSF) has been reported to increase the leukocyte count in subhuman primates subjected to total-body irradiation and in patients with the acquired immunodeficiency syndrome. We administered this substance to 19 patients with breast cancer or melanoma treated with high-dose combination chemotherapy and autologous bone marrow support. Groups of three or four patients were treated with 2.0, 4.0, 8.0, 16.0, or 32.0 micrograms per kilogram of body weight per day of glycosylated rHuGM-CSF by continuous intravenous infusion for 14 days, beginning three hours after bone marrow infusion. Total leukocyte and granulocyte recovery was accelerated in these patients as compared with 24 historical controls matched for age, diagnosis, and treatment. Leukocyte counts (mean +/- SD) obtained 14 days after transplantation were 1511 +/- 1003 per microliter in patients given 2 to 8 micrograms per kilogram per day, 2575 +/- 2304 in those given 16 micrograms, and 3120 +/- 1744 in those given 32 micrograms, as compared with 863 +/- 645 per microliter in the controls. No consistent effect on platelet counts was noted. Toxic effects were generally mild and not clearly dose-related in patients given 2 to 16 micrograms per kilogram per day. Edema, weight gain, or myalgias occurred in all patients given 32 micrograms per kilogram; marked weight gain, generalized edema, pleural effusions, and hypotension developed in two patients, one of whom also had acute renal failure. Our results indicate that rHuGM-CSF can accelerate myeloid recovery after high-dose chemotherapy and autologous bone marrow transplantation, over a range of doses that can be tolerated. In this setting the ability to increase the dose is limited by the development of myalgias and fluid retention.

We treated 115 patients in a phase I/II dose-escalation study of ifosfamide/carboplatin/etoposide (ICE) followed by autologous stem cell rescue. Patients treated had a variety of diagnoses, including breast cancer (high-risk stage II disease with eight or more positive nodes, stage III disease, and responsive metastatic disease), non-Hodgkin's lymphoma, Hodgkin's disease, acute leukemia in first remission, and various solid tumors that were responsive to induction therapy. Patients received autologous bone marrow stem cells or peripheral blood stem cells primed by one of several methods. The maximum tolerated dose of ICE was determined to be ifosfamide 20,100 mg/m2, carboplatin 1,800 mg/m2, and etoposide 3,000 mg/m2 when administered as a 6-day regimen. The dose-limiting toxicities included acute renal failure, severe central nervous system toxicity, and "leaky capillary syndrome" with hypoalbuminemia, profound fluid overload, and pulmonary insufficiency. Analysis of hematologic recovery based on stem cell source and influence of hematopoietic growth factor administration was undertaken. Hematopoietic growth factor use significantly reduced neutrophil engraftment time for patients receiving bone marrow stem cells, with evidence of earlier recovery times for patients receiving granulocyte colony-stimulating factor compared with granulocyte-macrophage colony-stimulating factor. Neutrophil recovery times varied based on the source of stem cells used, with the earliest engraftment times seen for patients receiving peripheral blood stem cells primed with cyclophosphamide and granulocyte colony-stimulating factor. Platelet recovery times were not statistically different for any of the subsets. In conclusion, the maximum tolerated dose of ICE has been defined, and the source of stem cells and the use of hematopoietic growth factors influence hematopoietic recovery.

Ischemic acute renal failure involves not only the kidney but also extrarenal organs such as the bone marrow that produces inflammatory cells. By ELISA and RNase protection assays, we now show that renal ischemia-reperfusion increases serum concentrations of granulocyte macrophage colony-stimulating factor (G-CSF) protein and increases both G-CSF mRNA and protein in the ischemic kidney. In situ hybridization localized the increased G-CSF mRNA to tubule cells, including medullary thick ascending limb cells (mTAL), in the outer medulla. We also show that mTAL produce G-CSF protein and increase G-CSF mRNA after stimulation by reactive oxygen species in vitro. The production of G-CSF by the kidney after ischemia-reperfusion provides a means of communication from the injured kidney to the bone marrow. This supports the known inflammatory response to ischemia.
