Abstract Purpose: We performed a phase II trial to evaluate the efficacy and the safety of gemcitabine monotherapy, a pyrimidine antimetabolite, in patients, who had previously failed anthracycline and taxane-based chemotherapy for the treatment of metastatic breast cancer.

Materials and Methods: Twenty-one patients with metastatic breast cancer, which was unresponsive to previous chemotherapy, were entered into this study. Gemcitabine was administered at 850 mg/m2, as a 60- minute intravenous infusion on days 1, 8 and 15. This regimen was repeated every 28 days with G-CSF support, but without dose reduction.

Results: Objective responses were seen in 6 of the 20 patients who were able to be evaluated (1 complete response and 5 partial responses), with an objective response rate of 30%. The median time to progression

was 5 (1¡­20) months, and the median overall survival duration was 11 (2¡­21) months. The actual dose intensity was 566.7 mg/m2/wk (range; 340¡­637.5 mg/m2/wk) and the relative dose intensity was 0.89 (range; 0.40¡­1.00). Toxicity was mainly hematological. Toxicities included: grade 3 neutropenia in 20% and anemia in 5%. Grades 3 and 4 thrombocytopenia occurred in 15% of the patients.

Conclusion: Gemcitabine monotherapy is an effective and safe treatment for refractory breast cancer patients heavily treated with the anthracycline and taxane- based regimen. Cancer Research and Treatment 2002;34:274⁣279)
