Abstract:
Purpose
Capecitabine is an oral fluoropyrimidine with considerable activity and minimal myelosuppression and alopecia. This phase I study evaluated the addition of capecitabine to epirubicin/docetaxel combination therapy as first-line treatment for advanced breast cancer.
Patients and methods
Twenty-three female patients with advanced breast cancer received capecitabine (7651060 mg/m2 twice daily on days 114 of a 3-week treatment cycle) in combination with epirubicin and docetaxel (75 mg/m2 i.v. on day 1).
Results
The maximum tolerated dose of capecitabine was 985 mg/m2 and the principal dose-limiting toxicity was febrile neutropenia. No grade 3/4 anemia or thrombocytopenia occurred. There were no grade 4 non-hematological events and grade 3 events other than alopecia were rare. Alopecia occurred in all patients and treatment cycles, and asthenia occurred in all patients and in 84% of treatment cycles. Other frequent adverse events included nausea, vomiting, fever, paresthesia and elevated transaminase levels. An objective response to treatment was observed in 91% (95% confidence interval 72% to 99%) of patients.
Conclusions
The addition of capecitabine to docetaxel/epirubicin combination therapy provides a well-tolerated and active first-line chemotherapy regimen in patients with advanced breast cancer, and merits phase II/III evaluation.
