Abstract

Primary treatment goals in less aggressive metastatic breast cancer (MBC) are prolonged survival, good quality of life and control of the disease and its symptoms. High activity, oral administration and no alopecia make capecitabine monotherapy attractive in slowly evolving disease. We retrospectively analysed 226 patients who had received single-agent capecitabine as 1st-line chemotherapy at our institution. The median interval between breast cancer diagnosis and MBC was 52 months (range 0-479); 76% had received endocrine therapy for MBC, 58% had visceral involvement and 30% had 3 or more metastatic sites. The median starting dose was 1,000 mg/m(2) twice daily. Disease was improved in 56% of the patients (median duration: 13.2 months) and stabilised in 20%. Median time to treatment failure was 8.8 months (95% CI: 7.1-10.5); median overall survival from initiating capecitabine was 23.6 months (95% CI: 19.7-27.4). Prior adjuvant chemotherapy, endocrine therapy for MBC, visceral disease, hormone receptor status and initial capecitabine dose did not influence time to treatment failure. Among 161 patients <75 years, 90% received further chemotherapy. Based on these findings, 1st-line capecitabine should be considered in slowly prog...Continue Reading
