BACKGROUND: We evaluated previously established regimens of capecitabine plus vinorelbine in older patients with advanced breast cancer stratified for presence versus absence of bone metastases. PATIENTS AND METHODS: Patients > or =65 years who had received no prior chemotherapy for advanced breast cancer received up to six 21-day cycles of vinorelbine 20 mg/m(2) i.v. on days 1 + 8 with oral capecitabine on days 1-14 (1,000 vs. 1,250 mg/m(2) daily in patients with vs. without bone involvement). RESULTS: Median age was 72 years in patients with bone metastases (n = 47) and 75 years in patients without bone metastases (n = 23). Response rates were 43% (95% confidence interval, CI, 28.3-58.8) and 57% (95% CI = 34.5-76.8), respectively. Median time to progression was 4.3 (95% CI = 3.5-6.0 months) and 7.0 months (CI = 4.1-8.3), respectively. Neutropenia was the most common toxicity, with grade 3/4 occurring in 43 and 39%, respectively. Pulmonary embolism was seen in 5 and grade 3 thrombosis in 3 patients. Other toxicities were mild to moderate. CONCLUSIONS: These regimens of capecitabine and vinorelbine are active and well tolerated in patients with advanced breast cancer > or =65 years. Response rates were comparable to published results. The lower capecitabine doses appeared appropriate given the advanced age, bone involvement and prior radiotherapy.
