Abstract
Purpose To evaluate the safety and efficacy of capecitabine in older women with advanced breast cancer. Patients and Methods Seventy-three eligible patients (median age, 73 years; range, 65 to 89 years) were enrolled. The first 30 patients received oral capecitabine 1,250 mg/m2 twice daily on days 1 to 14 every 21 days. Due to the occurrence of two toxic deaths, capecitabine 1,000 mg/m2 twice daily was given to the subsequent 43 patients. Results All patients were assessable for safety and efficacy. A total of 351 treatment cycles were administered (median, six per patient; range, one to eight cycles). Dose reductions due to toxicities were required in 30% of patients in the standard-dose group, but capecitabine was given without a dose reduction to 95% of patients in the low-dose group. Capecitabine demonstrated a favorable safety profile. The overall incidence of grade 3/4 toxicities was low: the most common events reported in ≤ 10% of the patients were fatigue, diarrhea, dyspnea, and nausea. In the sta...
