Standard Versus Continuous Capecitabine in Advanced Breast Cancer

Summary

Capecitabine is active in metastatic breast cancer but the conventional schedule (1250 mg/m2/12 hr 2 weeks on, one week off) produces grade 2 or greater hand and foot syndrome in up to 50% of patients leading to those reductions. There are theoretical reasons to administer S-phase specific agents in continuous, protracted rather than intermittent schedules. The investigators study compares the standard schedule (1250 mg/m2/12 hr 2 weeks on, one week off) with a continuous administration schedule (800 mg/m2/12hr). The latter administer approximately the same cumulative dose of capecitabine as the standard schedule. The study hypothesis is that grade 2 or greater hand and foot syndrome will be reduced from 50% (standard arm) to 20% (experimental arm). The investigators assume similar antitumor activity in both arms.
