Weekly intravenous recombinant humanized anti-P185HER2 monoclonal antibody (herceptin) plus docetaxel in patients with metastatic breast cancer: a pilot study.
Keywords
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.
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.
