Gómez-Bernal et al (abstract #341) report the results of a docetaxel (Taxotere)/vinorelbine (Navelbine) combination as second-line therapy for metastatic breast cancer. Both agents were administered on the same day and repeated every 14 days. The 52% objective response rate is impressive, since vinorelbine alone would be expected to produce a 20%–30% response rate in this setting, with docetaxel projected to achieve a 40% complete and partial remission rate. Therefore, the results suggest an additive interaction between the two agents.
