A 54-year-old woman underwent mastectomy and axillary lymph node dissection for infiltrating ductal carcinoma with multiple lymph node involvement. The patient received adriamycin 60 mg/m(2) and cyclophosphamide 600 mg/m(2) (AC) followed by weekly paclitaxel 80 mg/m(2) and external irradiation to the local lymph node regions as adjuvant treatment. After 1 year and 5 months, the patient suffered her first recurrence, developing multiple brain and meningeal metastases. CNS involvement was well controlled by oral capecitabine (2400 mg twice daily, on days 1-21 of a 28-day cycle) and external whole brain irradiation of 50 Gy with minimal toxicity. We suggest that capecitabine contributed to the favorable clinical course in this patient and believe that, as an oral agent, this drug may benefit patients with CNS metastases of breast cancer by allowing home-based therapy.
