BACKGROUND: Treating patients with anthracycline- and taxane-pretreated metastatic breast cancer is challenging. This study evaluated the activity and safety of a combination of cisplatin and capecitabine in this setting. PATIENTS AND METHODS: Thirty-nine consecutive patients entered the study. All had experienced failures or relapse after previous treatment with anthracyclines and taxanes plus/minus other chemotherapeutic regimens. The present treatment consisted of intravenous cisplatin 20 mg/m(2) every week for 6 weeks, followed by 1 week of rest, and oral capecitabine 1,000 mg/m(2) twice daily for 14 days, followed by a 7-day rest period. RESULTS: Objective response was obtained in 14 patients (35.9%), with complete remission in 3 (7.7%). Median time to progression was 5.2 months and survival was 10.9 months in the entire population and 8.7 and 16.5 months in the responding patients, respectively. The dose-limiting toxicity for the regimen was leucopenia, while gastrointestinal discomfort was the most frequent cause of capecitabine reduction or delay. CONCLUSIONS: The cisplatin and capecitabine combination regimen is active and manageable. It seems to be non-cross resistant to anthracyclines and taxanes.

Abstract
BACKGROUND: Treating patients with anthracycline- and taxane-pretreated metastatic breast cancer is challenging. This study evaluated the activity and safety of a combination of cisplatin and capecitabine in this setting. PATIENTS AND METHODS: Thirty-nine consecutive patients entered the study. All had experienced failures or relapse after previous treatment with anthracyclines and taxanes plus/minus other chemotherapeutic regimens. The present treatment consisted of intravenous cisplatin 20 mg/m(2) every week for 6 weeks, followed by 1 week of rest, and oral capecitabine 1,000 mg/m(2) twice daily for 14 days, followed by a 7-day rest period. RESULTS: Objective response was obtained in 14 patients (35.9%), with complete remission in 3 (7.7%). Median time to progression was 5.2 months and survival was 10.9 months in the entire population and 8.7 and 16.5 months in the responding patients, respectively. The dose-limiting toxicity for the regimen was leucopenia, while gastrointestinal discomfort was the most frequent cause of capecitabine reduction or delay.
