Abstract

BACKGROUND. This Phase II multicenter study evaluated the efficacy and toxicity of paclitaxel (200 mg/m2 by 3-hour infusion) with carboplatin (area under the curve 6 mg/mL per minute) administered every 3 weeks as first-line therapy for women with metastatic breast carcinoma. METHODS. Eligible patients had measurable metastatic disease and an Eastern Cooperative Oncology Group performance status of 0-2. Prior adjuvant chemotherapy, including anthracycline-based therapy, was allowed, as was prior hormonal therapy as part of either adjuvant treatment or treatment for metastasis. Prior therapy with taxanes or platinum was not allowed. RESULTS. A total of 53 patients were enrolled in this study, with 50 patients evaluable for response and toxicity. The overall response rate was 62% (95% confidence interval [CI], 48-75%); 16% of patients had complete responses and 46% had partial responses. The median time to progression was 7.3 months (95% CI, 5.9-12.9), and the 12-month survival estimate was 72% (95% CI, 61-86%). Therapy was generally well tolerated. Grade 3-4 neutropenia was the predominant toxicity, observed in 82% of patients, but there were no episodes of febrile neutropenia or sepsis. Hematopoietic growth factors were not routinely necessary. Grade 3 peripheral neuropathy occurred in 16% of patients. CONCLUSIONS. Paclitaxel (200 mg/m2) with carboplatin (area under the curve 6 mg/mL per minute) demonstrated substantial efficacy in patients with metastatic breast carcinoma, and the 12-month survival rate of 72% was encouraging. This therapy represents a viable option for patients with metastatic disease.
