Abstract
BACKGROUND: In patients with HER2-positive metastatic breast cancer (MBC), combined treatment of herceptin (H) and chemotherapy (CT) improves time to progression, response rates and survival compared with CT alone. MATERIALS AND METHODS: We evaluated the safety and efficacy of weekly Docetaxel combined with weekly H as treatment in HER2 overexpressing MBC. RESULTS: Preliminary toxicity data from 12 patients and 76 cycles of D and 80 cycles of H were analysed. No G3/4 toxicity was observed. The most frequent non-hematologic toxicities were fatigue (2 patients G2, 2 patients G1), dyspepsia (1 patients G2, 3 patients G1), diarrhea (1 patient G2, 3 patients G1), and nausea (1 patient G2, 3 patients G1). Six partial responses have been observed in 12 patients (ORR 50%). CONCLUSIONS: The combination of weekly Docetaxel and Herceptin is well tolerated with significant anti-tumor activity.
