Vinorelbine as palliative therapy in advanced breast cancer

Thirty advanced breast cancer patients received Vinorelbine (VNB) according to two different schedules: a weekly i.v. bolus of 30 mg/m (14 patients) or a continuous infusion (CI) schedule comprising 8 mg i.v. bolus on day 1 followed by 8 mg/m2/die CI day 1 to 4, q 21 days (16 patients). 36% of patients had received at least two prior chemotherapy regimens for advanced disease and 57% had been treated with anthracycline-based palliative therapy. The overall response rate (CR + PR) was 33% (soft tissue 57%, bone 17%, viscera 29%). The main toxicities were neutropenia and abdominal pain. Vinorelbine is effective in pretreated advanced breast cancer patients.
