Taxanes in breast cancer: an update.

Over the past decade the taxanes have proved to be fundamental in the treatment of breast cancer. Initially found to have efficacy in metastatic breast cancer, the taxanes are now vital components in the treatment of early-stage disease, in which their addition to adjuvant treatment of early breast cancer has been shown to improve overall survival. In addition, the taxanes have demonstrated a role in first-line therapy for metastatic disease, with some of the highest efficacy of any class of chemotherapy. Targeted therapies in combination with the taxanes have further improved survival for both early and metastatic disease. New formulations of taxanes may both improve antitumor activity and reduce toxicity.
