Purpose: The trial was undertaken to study the effect of administering granulocyte-macrophage colony-stimulating factor (GM-CSF) with and without peripheral-blood progenitor cells (PBPC) on the hematologic and nonhematologic toxicity observed with multiple cycles of high-dose carboplatin chemotherapy. Patients and Methods: Eighteen patients with a variety of solid tumors received a total of 40 cycles of carboplatin, 1,200 mg/m2 per cycle, administered by continuous infusion over 96 hours. All 40 courses were administered with a daily 4-hour intravenous (IV) infusion of either 5 or 10 μg/kg/d of recombinant human Escherichia coli-derived GM-CSF. The first 20 courses were administered without PBPC support (treatment A). Because of severe neutropenia and thrombocytopenia, the next 20 courses of therapy were administered with GM-CSF, PBPC, and oral antibiotic prophylaxis (treatment B). Results: The addition of PBPC support led to a significant reduction in the duration of neutropenia (10.5 v 7.5 days; P = .027) and thrombocytopenia (12.4 v 5.2 days; P = .001), number of RBC transfusions (six v three; P = .01) and platelet transfusions (10.3 v 3.7; P = .013), number of hospital days (12.6 v 2.9; P = .01), and days of IV antibiotics (11.8 v 2.4; P = .007) per cycle. Significant increases in the weekly dose intensity (206 v 285 mg/m2/ wk; P = .014) and total dose (2,287 v 3,600 mg/m2; P = .018) of carboplatin delivered were also observed with treatment B. The overall response rate in this study was 70%, with 11 of 16 assessable patients achieving either a complete (three patients) or partial (eight patients) remission. Conclusion: This combination of GM-CSF and PBPC infusion represents an effective method for delivering multiple cycles of high-dose carboplatin chemotherapy and may serve as a model for the administration of high-dose chemotherapy in future trials.
