BACKGROUND: Optimal chemotherapy (CT) for advanced breast treatment should be effective, well tolerated and convenient. In this study the efficacy and safety of the fully oral combination of oral vinorelbine (Navelbine Oral) plus capecitabine (Xeloda) in metastatic breast cancer (MBC) patients pretreated with anthracycline, was evaluated. PATIENTS AND METHODS: In this phase II multicenter study, this combination CT was given as a first- or second-line therapy for MBC. The treatment schedule was: oral vinorelbine 60 mg/m2 day 1 and day 8 plus capecitabine 1,000 mg/m2 twice daily from day 1 to day 14, every 21 days. RESULTS: One hundred and fifteen patients were included in this trial. The median age was 58 years (range: 40-75). All the patients had received prior anthracycline-based chemotherapy. The combination was well tolerated, with, in particular, only 0.8% of patients presenting with febrile neutropenia. In the intention-to-treat (ITT) population, an objective response was achieved in 65 patients (56.5%). A complete response was achieved in 22 patients (19.1%); partial response in 43 patients (37.4%); stable disease in 36 patients (31.3%), and progressive disease was observed in 14 patients (12.2%). After a median follow-up of 10.0 months, the median progression-free survival (PFS) was 10.5 months and the median survival was 17.5 months. CONCLUSION: Oral vinorelbine-capecitabine shows very promising activity and low toxicity in MBC treatment, with high compliance of the patients.

BACKGROUND: This multicentre, international phase II trial evaluated the efficacy and safety profile of a first-line combination of oral vinorelbine plus capecitabine for women with metastatic breast cancer (MBC). METHODS: Patients with measurable, HER2-negative disease received, as a first line in metastatic setting, 3-weekly cycles of oral vinorelbine 80 mg m(-2) (after a first cycle at 60) on day 1 and day 8, plus capecitabine 1000 mg m(-2) (750 if >or=65 years of age) twice daily, on days 1-14. Treatment was continued until progression or unacceptable toxicity. RESULTS: A total of 55 patients were enrolled and 54 were treated (median age: 58.5 years). Most (78%) had visceral involvement and 63% had received earlier (neo)adjuvant chemotherapy. The objective response rate (RECIST) in 49 evaluable patients was 51% (95% confidence interval (CI), 36-66), including complete response in 4%. The clinical benefit rate (response or stable disease for >or=6 months) was 63% (95% CI, 48-77). The median duration of response was 7.2 months (95% CI, 6.4-10.2). After a median follow-up of 41 months, median progression-free survival was 8.4 months (95% CI, 5.8-9.7) and median overall survival was 29.2 months (95% CI, 18.2-40.1). Treatment-related adverse events were manageable, the main grade 3-4 toxicity was neutropaenia (49%); two patients experienced febrile neutropaenia and three patients had a neutropaenic infection (including one septic death). A particularly low rate of alopaecia was observed. CONCLUSION: These results show that the all-oral combination of oral vinorelbine and capecitabine is an effective and well-tolerated first-line regimen for MBC.
