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/m(2) twice daily on days 1 to 14
every 21 days. Due to the occurrence of two toxic deaths, capecitabine 1,000
mg/m(2) 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 standard-dose group, the response rate was 36.7%
(95% CI, 19.9% to 56.1%). An additional seven patients had disease stabilization
at >/= 24 weeks. In the low-dose group, the response rate was 34.9% (95% CI, 21%
to 50.9%). An additional 15 patients had prolonged stabilization. The median
time to disease progression was 4 months in either group.
CONCLUSION: This study shows that capecitabine is safe and effective in the
elderly breast cancer patient. Based on the overall results, the capecitabine
dose of 1,000 mg/m(2) twice daily merits consideration as "standard" for older
patients who do not have severely impaired renal function.
