Vinorelbine (navelbine) as a salvage treatment for advanced breast cancer
Abstract
Background: Vinorelbine (Navelbine), a new vinca alkaloid, is an effective drug in breast cancer. Our study was undertaken to assess the efficacy and tolerance of Navelbine in refractory advanced and/or metastatic breast cancer (AMBC).
Patients and methods: One hundred heavily pretreated patients with AMBC entered the study and were scheduled to receive 30 mg/m2 of Navelbine weekly by a 20 min i.v. infusion with dose adjustments according to tolerance. All patients had previously received at least one chemotherapy regimen including an anthracycline for advanced disease.
Results: Sixteen of the 100 assessable patients responded (1 complete response and 15 partial responses), for an overall response rate of 16% (IC 95: 8%-23%). The median duration of response was 5 months (3-18). Responses were seen in lymph nodes (13/27), breast (11/34), soft tissue and skin (13/36), lung (3/14) and liver (2/25), but not in bone metastases. The main toxicities (WHO grade > or = 3) were granulocytopenia and anemia in, respectively, 51% and 9% of all 100 eligible patients. Thrombocytopenia and other non-haematological toxicities consisting of peripheral neuropathy, constipation, nausea/vomiting, alopecia and phlebitis were rare and mild.
Conclusion: Vinorelbine is an active drug in AMBC, particularly in breast, lymph nodes and skin/soft tissue sites, with an excellent tolerance. Since the mean dose intensity was 19.7 mg/m2/week, a dose of 20 mg/m2/week is recommended for heavily pretreated patients (radiotherapy and chemotherapy).
