Paclitaxel (Taxol) is a diterpene originally obtained from the bark of the Pacific Yew Tree, Taxus Brevifolia. Its mechanism of action is unique. It stabilizes microtubule polymerization, thus blocking cells in the G2/M phase of the cell cycle. In breast cancer, initial studies using paclitaxel demonstrated high activity. The first study was reported in 1991 by Holmes et al who gave paclitaxel as a 24-hour infusion at 250 mg/m2 to 25 patients with metastatic breast cancer following only one prior chemotherapy regimen--they achieved a 56% response rate. Since then, numerous studies have confirmed the effectiveness of paclitaxel in patients with metastatic disease. A second taxane, docetaxel (Taxotere), has also demonstrated excellent activity. Clinical research is now focused on integrating the taxanes into combination drug regimens and into neoadjuvant and adjuvant schedules for patients with early stage breast cancer, as well as looking at the biologic determinants of response and resistance to taxanes. This article will review developments in the use of taxanes in the adjuvant and neoadjuvant settings and it will review the information on possible molecular markers that may be useful in predicting tumor responsiveness to taxanes. |
