Treatment of metastatic breast cancer with vinorelbine and docetaxel.
OBJECTIVE
A phase II study was performed to evaluate efficacy and safety of the combination vinorelbine and docetaxel in patients with metastatic breast cancer previously treated with anthracycline-based regimens. Overall 41 patients were included in the study.


METHODS
Treatment consisted of vinorelbine 25 mg/m2 and docetaxel 75 mg/m2, both administered on day 1 every 3 weeks for a maximum of 9 cycles. Most patients (92%) were postmenopausal with a median age of 57 years, and median ECOG performance of 1. Sites of disease were viscera in 42% of patients, bones in 30%, soft-tissues in 32%. Sixty-five percent of patients had >2 metastatic sites. Previous treatments included neo-adjuvant chemotherapy in 7.3% of cases, adjuvant chemotherapy in 71%, and front-line chemotherapy for advanced disease in 50% of cases.


RESULTS
A total of 273 cycles of chemotherapy were delivered (mean 6 cycles/patient). All patients were assessable for toxicity: alopecia was recorded in all patients, grade 2-3 neutropenia in 34% and grade 4 in 9.7%; grade 2-3 nausea/vomiting in 29%, grade 2-3 mucositis in 24.3%. Out of 39 patients evaluable for response, 7 (18%) complete responses and 13 (33%) partial responses have been recorded with an overall response rate of 51%. Six patients (15%) experienced stable disease and 13 patients (33%) progressed. Mean duration of responses was 15.2 months. Median time to progression and median overall survival were 6.2 and 14 months, respectively.


CONCLUSIONS
In patients with metastatic breast cancer previously treated with anthracyclines the combination vinorelbine-docetaxel is very active and well tolerated representing a valid therapeutic option for the management of this patient population.
