Combination chemotherapy with docetaxel plus vinorelbine in metastatic breast cancer patients with prior exposure to anthracyclines.
OBJECTIVE
To evaluate the anti-tumor activity and tolerance of docetaxel plus vinorelbine in metastatic breast cancer (MBC) patients previously treated with anthracyclines.


METHODS
Fifty patients with MBC were treated with docetaxel 75 mg/m2 (subsequently reduced to 60 mg/m2) plus vinorelbine 30 mg/m2 (subsequently reduced to 24 mg/m2). both on day 1, every 3 weeks, for a maximum of six cycles. All patients had previously received anthracyclines as adjuvant treatment (< 12 months disease-free interval) or first-line therapy for MBC. Thirty-seven patients had received at least one prior regimen for MBC. Twenty-five patients had prior high-dose chemotherapy with stem-cell rescue. Thirty patients had multiple metastatic sites. Liver and lung disease were the predominant metastatic site in 31 patients.


RESULTS
Forty-nine patients were assessable for response. Nineteen patients achieved a partial response and four a complete response (overall response rate, 46%; 95% confidence interval (95% CI): 32%-60%). Fourteen patients (28%) had stable disease on treatment. Median Kaplan-Meier estimated progression-free and duration of response times are 21 and 29 weeks. Median survival time is 47 weeks. Hematological dose-limiting toxicity, prompted a 20% dose reduction for both drugs after the first thirteen patients were treated. Neutropenia > or = grade 3 occurred in nineteen (34%) patients, neutropenic fever in 15 (7) courses, and mucositis > or = grade 3 in 6 (3%) courses.


CONCLUSIONS
The combination of docetaxel plus vinorelbine on day 1 every 3 weeks is feasible and active in MBC patients with prior anthracycline exposure. This regimen is safe, well-tolerated and convenient for the patients.
