Abstract

Purpose: We conducted a phase II study evaluating safety and efficacy of combination gemcitabine and capecitabine therapy for metastatic breast cancer patients following anthracycline and taxane treatment in Korea. Methods: This was a single-arm, non-randomized phase II study. Patients received 1,000 mg/m2 gemcitabine intravenously over 30 min on days 1 and 8, and 1,250 mg/m2 capecitabine orally twice daily on days 1-14 until disease progression or intolerable toxicity occurred. This regimen was repeated every 3 weeks. The primary outcome assessed was overall response rate [ORR, complete response (CR) + partial response (PR) as the best response], and secondary outcomes were progression-free survival (PFS), overall survival (OS), disease control rate (DCR) [maintenance of CR + PR + stable disease (SD) for at least 3 months], drug toxicity, and predictive factors for response to this regimen. Results: Of 41 patients, the ORR was 39.0 % (CR 0 %; PR 39.0 %), and DCR was 78.0 % using this chemotherapy. DCR for 6 and 12 months was 68.3 and 26.8 %, respectively. Median PFS was 10.0 months [95 % confidence interval (CI) 7.8-12.1], and median OS was 25.1 months (95 % CI 18.2-32.1). Prominent toxicities were neutropenia and hand-foot syndrome. Most adverse events were well known, relatively moderate, and reversible. Taxane sensitivity [odds ratio (OR) 0.169; 95 % CI 0.034-0.826; P = 0.028] and hepatic metastasis (OR 0.097; 95 % CI 0.017-0.559; P = 0.009) were significantly predictive of response to gemcitabine and capecitabine combination. Conclusions: This study showed reproducible anticancer activity and tolerable toxicity of gemcitabine and capecitabine combination therapy in recurrent or metastatic Korean breast cancer patients previously treated with anthracycline and taxane.
