A Phase I study was conducted to determine whether the addition of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) to a combined 5-fluorouracil (5-FU) and folinic acid (FA) regimen would allow an escalated starting dose of 5-FU. FA (500 mg/m2) was administered as a 2-hour infusion on days 1 through 5, with 5-FU administered as a bolus injection 1 hour after the initiation of FA. Fifteen patients were enrolled in the trial; six were entered at a dose level of 375 mg/m2 of 5-FU, six at 450 mg/m2, and three at 540 mg/m2. rhGM-CSF was administered subcutaneously on days 6 through 15. A course of therapy was repeated every 28 days. Serious toxicity was observed at 450 mg/m2, with two patients developing grade 3 mucositis and one, grade 4 mucositis. Dose-limiting toxicity occurred at 540 mg/m2, at which point three patients developed grade 4 mucositis. One patient with metastatic colon cancer who received 5-FU at 540 mg/m2 achieved a partial response. Because of this persistent mucositis, the addition of rhGM-CSF used in this schedule would not allow an increased starting dose of 5-FU.

We evaluated the effect of oral ciprofloxacin on neutrophil recovery in 20 consecutive patients undergoing autologous bone marrow transplantation (BMT) for malignant lymphoma and compared the results with a control group of 20 patients receiving co-trimoxazole and folinic acid. Both groups started the prophylactic antibiotic as well as granulocyte-macrophage colony-stimulating factor (GM-CSF) the day after marrow infusion and continued the former until the onset of febrile neutropenia (median duration of treatment 6 days for co-trimoxazole and 7 days for ciprofloxacin). The time of attain an absolute neutrophil count > or = 0.5 x 10(9)/L was significantly shorter in patients receiving ciprofloxacin (16 days vs 22 days; P = 0.006). There was no difference in time to attain a platelet count > or = 20 x 10(9)/L independent of transfusion or in time to the first febrile episode or incidence of bacteremia. We conclude that antibiotic prophylaxis with ciprofloxacin results in more rapid neutrophil recovery than prophylaxis with co-trimoxazole. This may result from a myelosuppressive effect of co-trimoxazole or an enhancement of neutrophil recovery by ciprofloxacin, or both.
