Abstract
Background: To compare survival between patients with advanced breast cancer (ABC) treated with epirubicin/paclitaxel (Taxol) or paclitaxel/carboplatin (Cp) chemotherapy. Patients and methods: From January 1999 to April 2002, 327 eligible patients with ABC were randomized to receive either paclitaxel 175 mg/m2 in a 3-h infusion followed by epirubicin (EPI) 80 mg/m2 (group A) or paclitaxel, as in group A, followed by Cp at an AUC of 6 mg × min/ml (group B) every 3 weeks for six cycles. Results: After a median follow-up of 23.5 months, median survival was not significantly different between the two groups (22.4 months versus 27.8 months, P=0.25), whereas median time to treatment failure was significantly longer in patients treated with paclitaxel/Cp (8.1 months in group A versus 10.8 months in group B, P=0.04). Both regimens were well tolerated. In total, 39 patients (24%) in group A and 46 (29%) in group B suffered at least one severe side-effect. Quality-of-life assessment and cost analysis did not reveal any significant differences between the two groups. Conclusion: Our study suggests that the paclitaxel/Cp combination is an effective therapeutic alternative for patients with ABC in which anthracycline administration has the potential of being harmful.
