摘要
Background There are no data on more tolerable capecitabine doses in elderly patients in Chinese population. The aim of this study was to evaluate the activity and safety of capecitabine combined with weekly docetaxel for the treatment of anthracycline-resistant metastatic breast cancer （MBC） in older Chinese patients. Methods MBC patients aged 〉65 years pretreated with 1-5 prior chemotherapy regimens, including an anthracycline, received oral capecitabine 825 mg/m^2 twice daily, days 1-14, plus docetaxel 30 mg/m^2 on days 1 and 8 every 21 days. All 41 enrolled patients received at least 1 dose of treatment and were evaluable for safety; 38 received at least 2 cycles （median 4, range 2-8） and were evaluable for efficacy. Results The overall objective response rate was 47%, including complete responses in 8% of patients. Median time to progression was 8.9 months. Median overall survival was 17.6 months. The most common side effects were haematological and gastrointestinal toxicities and hand-foot syndrome. The only grade 3/4 adverse events were neutropenia （12%）, alopecia （7%）, grade 3 nausea and vomiting （2%） and grade 3 nail toxicity （2%）. Conclusions Capecitabine 825 mg/m^2 twice daily plus weekly docetaxel is active with an acceptable safety profile in Chinese women 〉65 years with anthracycline-resistant MBC. Efficacy and tolerability compare favourably with previously reported trials evaluating higher capecitabine doses in combination with 3-weekly or weekly docetaxel.
