We assessed the efficacy of a regimen consisting of four cycles of cyclophosphamide, Adriamycin (Adria Laboratories, Inc, Columbus, Ohio), cisplatin (CAP) followed by maintenance with cyclophosphamide, 5-fluorouracil, prednisone (CFP) compared with CFP alone in a randomized trial of 86 patients with advanced breast cancer. The objective regression rates were 46% (CFP) and 49% (CAP with CFP) which included complete regression rates of 7% (CFP) and 4% (CAP with CFP). The median time to progression was nine months for CFP and six months for CAP with CFP. Median survival in the CFP group was 18 months v 11 months in the CAP recipients. Due to the therapeutic trend in favor of patients receiving CFP, we terminated the study before achieving our initially projected accrual. We observed over a twofold excess of substantial nausea and vomiting among patients receiving the platinum-based regimen. In our view, the CAP followed by the CFP regimen is a more toxic program that offers no clinically meaningful improvement over CFP to patients with advanced breast cancer.
