PURPOSE A potential application of hematopoietic growth factors is to obtain an increased dose-intensity. This can be achieved by either higher doses of chemotherapy with standard intervals, or by standard doses with shorter intervals. The potential of these approaches has not been investigated systematically. PATIENTS AND METHODS In a randomized, multicenter study, 49 advanced breast cancer patients were treated with granulocyte colony-stimulating factor (G-CSF) and either increasing doses of epirubicin and cyclophosphamide with fixed intervals (arm one) or progressively shorter intervals with fixed doses of epirubicin and cyclophosphamide (arm two). A cohort of at least six patients was studied at each interval/dose. A more intensified interval/dose was given if less than 50% of patients encountered a dose-intensity limiting criterium (DILC) in the first three courses. RESULTS In arm one, epirubicin 140 mg/m2 and cyclophosphamide 800 mg/m2 every 21 days was too toxic. Subsequently, epirubicin 120 mg/m2 and cyclophosphamide 700 mg/m2 was tested with two of 10 patients encountering a DILC. All initial DILCs consisted of febrile neutropenia. In arm two, epirubicin 75 mg/m2 and cyclophosphamide 500 mg/m2 could be administered safely with 14- and 12-day intervals. In the 10-day interval, eight of 12 patients completed the first three cycles without a DILC. In the 8-day interval, seven of eight patients encountered a DILC. Incomplete neutrophil recovery, and to a lesser extent stomatitis, were dose-limiting. CONCLUSION In combination with G-CSF, epirubicin 120 mg/m2 and cyclophosphamide 700 mg/m2 every 21 days was feasible (projected dose-intensity, 40 mg/m2/wk and 233 mg/m2/wk, respectively). Epirubicin 75 mg/m2 and cyclophosphamide 500 mg/m2 could be administered safely every 10 days, allowing a projected dose-intensity of 52.5 mg/m2/wk and 350 mg/m2/wk, respectively.

PURPOSE: A multicenter phase II trial was performed to investigate the efficacy and tolerance of docetaxel, vinorelbine with or without recombinant human granulocyte colony-stimulating factor (G-CSF) in patients with metastatic breast cancer. PATIENTS AND METHODS: Between February 1998 and March 1999, 57 patients participated in this trial. Forty-two patients received this combination as first-line and 15 patients as second-line chemotherapy, including 10 patients who had failed anthracyclines. Therapy consisted of vinorelbine 30 mg/m2 on days 1 and 15 and docetaxel 30 mg/m2 on days 1, 8, and 15 every 4 weeks. Depending on the absolute neutrophil counts on the day of scheduled chemotherapeutic drug administration, a 5-day course of G-CSF 5 μg/kg/d was given. RESULTS: The overall response rate was 64.3% (95% confidence interval, 48.1% to 78.4%) in patients receiving docetaxel plus vinorelbine as first-line chemotherapy, including eight complete (19%) and 19 partial remissions (45.3%); 11 patients (26.2%) had disease stabilization, and only four (9.5%) progressed. Second-line treatment with this regimen resulted in eight (53.3%) of 15 objective responses, four had stable disease, and three had progressive disease. The median time to progression was 12 months in the first-line and 9.8 months in the second-line setting, respectively. After a median follow-up time of 18 months, 38 patients (65%) were still alive with metastatic disease. Myelosuppression was commonly observed; World Health Organization grade 3 or 4 neutropenia both occurred in 18 patients (32%) and was complicated by septicemia in four cases; grade 3 or 4 thrombocytopenia was seen in two patients (4%), and grade 3 anemia was seen in only one patient (2%). Severe (grade 3) nonhematologic toxicity, except for alopecia, was rarely observed and included nausea/vomiting in two patients (4%), and stomatitis, peripheral neuropathy, and skin toxicity each in one patient. CONCLUSION: Our data suggest that docetaxel and vinorelbine with or without G-CSF is an effective and fairly well tolerated regimen for the treatment of advanced breast cancer. It might be particularly useful in patients previously exposed to adjuvant or palliative anthracyclines and/or alkylating agents.
